    Quite a complex situation today, however, I'll try and get my head around what may likely occur over the next 24hrs.

    Currently sfc and upper low to SW of Ireland is moving East into the Bay of Biscay, ahead of it a warm moist SWerly flow is advecting airmass of high theta-w values NE across Wern france, ais of theta-w plume which has become destabilised by a short-wave trough approaching from the West and is currently producing an MCS with sferics over Wern France. This unstable plume is likely to affect Sern England later. Wind convergence again will likely trigger heavy showers over England and Wales today. Also stalling Cold front over Nern England with much cooler stable air to the North will be the focus of some heavy showery rain too today:

    Warm moist plume is expected to advect across Sern and central England and Wales through the day and increase sfc moisture, intially airmass over Sern England will be capped (as per 00z Brest, Cambourne soundings), however wind convergence is likely to spark off scattered heavy showers across much of England and Wales, also upper trough and surface cold front plus wind convergence over Nern England will likely to trigger heavy showers here too. CAPE charts suggest Midlands and East Anglia are likely to see best chance of isolated thunderstorms today.

    post-1052-1181719890_thumb.pngpost-1052-1181719734_thumb.png

    Later, GFS is modelling the MCS over NW France this afternoon to drift NE across the channel, as mid-level lapse rates steepen with upper trough arriving from the SW during the evening and overnight, this is likely to bring heavy rain with possible thunder overnight across Sern and SE England.

    Estofex have a level 1 warming (very slight risk of severe weather) for parts of southerm england for later on into the evening.

    Estofex Forecast

    Forecast SkewT for London during the evening shows some low level wind veer with a moderate jet at 850hPa which are wind parameters which could be condusive to tornado formation. The profile however is fairly moist all the way up and stable so any imports probably will not be boundary based and so the tornado risk is almost non existant.

    Although the troughs and frontal boundary to the south west will be moving north east individual storms along these areas will follow steerage winds and have a north wards movement.Late afternoon severe storms over France are likely to move north across the south eastern part of the UK.Whether they remain severe is in doubt.

    Looking a little early towards this afternoon then GFS deviates slightly from UKMO fax charts on the positioning of the frontal boundary moving up from the south. Satellite loops show it moving quickly and perhaps more enhanced to the south west of the UK than forecasts suggest. GFS does sugegst a moderately strong loop of upper level vorticity moving in later.

    Very warm moist air is being advected (moved) from the south across the UK which is being squashed by the cold front to the north and the boundary moving up from the south.

    High Cape levels seem driven by temperatures and this I think may be what limits thunderstorm activity over the UK with cloud limiting temperatures.

    Satellite pictures show current developments.

    I think we can expect some sharp showers moving up from the south west during today. Forecast skewT's suggest some low level veering of winds which could make things interesting although winds at 850hPa look a little light for a serious tornado risk.

    Chance of a few thunderstorms today with perhaps South Wales and the south west being prime spots. The main feature of today is an occulded slow moving frontal system moving north which looks set to bring a fair amount of rain to most areas. There is some suggestion that as temperatures rise the band of rain will turn convective but forecast air profile suggest deep moisture which will keep things messy and prevent any strong updraughts from forming. There is perhaps some suggestion of low level veering as the band passes over but 850hPa winds are weak suggesting little in the way of a horizontal vorticity source.

    Behind the rain band with cooler drier air aloft then we are into pretty unstable air with only a trigger required to set things off. Perhaps some sea breezes in the south west or across wales might provide the trigger.

    With steeper lapse rates tomorrow we potentially have fairly instable air with lots of Cape available.

    Forecast SkewT's show fairly light winds which would suggest some slow moving pulse type storms forming along convergence zones.

    With light winds some low level veering and some reasonable strong initial updraughts then none mesocyclonic funnels or spouts could form where convergence takes place. These are usually weak and rarely reach the ground.

    It is still a little early to be clear about tomorrow though and convergence features along with amounts of Cape and positioning of cloud are likely to be subtly different.

    A classic day of storms likely to develop along a wind convergence line, GFS models the line from S Wales ENE to the Wash - current wind map suggests this convergence line maybe slightly further North on it's Western extent to be more from Mid-Wales Eastwards:

    post-1052-1181891074_thumb.pngpost-1052-1181891082_thumb.png

    00z Cambourne ascent suggests an unstable airmass advecting North - rather moist profile upto around 500mb combined with steep mid-level lapse rates producing moderate CAPE values, surface heating likely to increase CAPE through the day in this airmass:

    post-1052-1181891302_thumb.pngpost-1052-1181891310_thumb.png

    A jet streak up the Eastern side of the UK this afternoon would suggest possible divergence of upper winds which will aid lift of air too, 0-6km deep layer wind shear is also likely to increase towards the Eastern side of England - 30-40kts would suggest multicellular storms are possible, dry air intrusion associated with the jet streak will also aid convection and increase threat of hail:

    post-1052-1181891546_thumb.pngpost-1052-1181891531_thumb.png

    So Southern/Mid Wales, the Midlands and over to Lincolnshire/Cambridgeshire area look favoured for thunderstorm development this afternoon along the wind convergence boundary, other storms may develop from the outflow boundaries of these storms as well. With the unstable airmass, other scattered storms away from the wind convergence line are possible due to surface heating and increasing lift from aloft, areas towards South Coast most likely to escape with a dry sunny afternoon.

    A decent possibility of funnel clouds this afternoon due to wind convergence causing low-level vorticity and stretching of updrafts. With a very moist profile to the atmosphere, torrential downpours with flooding is a real possibility. Hail looks less likely unless drier air aloft arrives - which seems possible by the evening in the East.

    Yes I largely agree with Nick and the Estofex forecast.

    Estofex Forecast

    Forecast SkewT shows plenty of Cape available and as Nick says moisture all the way up which might limit the hail threat till later.

    Low level wind forecast give a convergence zone across southern central england which should be a focus for storms to develop.

    Low wind shear increasing eastwards ,light low level winds veering near the convergence zone suggest there is a chance of non mesocylonic funnels (weak short lived generally not reaching the ground) and perhaps further east late on drier air aloft and higher wind shear could give a conditions favourable for a slightly longer lived tornado.

    There is plenty that can change for instance there is a possible new frontal boundary swinging north and overriding any convergence zone. A very moist profile all the way up could give plenty of cloud without any focus inhibiting convection.

    So it is going to be a case of watching the Satellite and radar pictures to see how things develop.

    My tip would be that some storms are likely over the south west where sea breeze convergence takes place also expect storms to reach further north than 00Z GFS suggests and finally watch any storms in the East late afternoon.

    Rather moist SW'erly flow in the lower troposphere covers the UK today, 00z Cambourne ascent suggests a very moist profile upto 700mb with steep mid-level lapse rates:

    post-1052-1182151687_thumb.png

    ... surface heating of this airmass is likely to increase CAPE values.

    The airmass over England and Wales is likely to become unstable through uplift of an upper trough moving in from the SW, lapse rates are likely to increase with arrival of upper trough and scattered heavy showers with thunder are likely. GFS indicates that SW and Central Southern England, West Country, Midlands, Wales and later parts of Nern England and SW Scotland are likely to see the greatest chance of heavy showers and thunderstorms, lighter showers towards the East and SE. Becoming drier over Sern areas by evening.

    post-1052-1182151958_thumb.pngpost-1052-1182151967_thumb.png

    Not much directional wind shear today with SW winds through much of the troposphere, perhaps some speed shear aloft towards the S/SW near a jet streak - so organisation into bowing multicells is possible, otherwise generally well scattered non-severe storms, with no apparent wind convergence and strong low-level or deep layer wind shear generally -funnels or tornadoes don't look too likely atm.

    Mid-level Dry air intrusion suggested to arrive across SW later may enhance convection and increase threat of hail in any showers over Wales and the Midlands:

    Area of vorticity can be seen on current satellite pictures to the south of Wales and southern Ireland which conincides quite nicely with the GFS 300hPa vorticity charts for now.

    Forecast suggests the area of vorticity extends eastwards during the day to form a trough moving northwards.

    Little break in cloud cover is likely to limit storm intensity as temperatures are held back. Forecast skewT's suggest moisture all the way up with very little wind shear and moderate instabilty. 850-500hPA lapse rates do not look that high

    Low level wind speeds are low and cloud bases should be low which might suggest conditions favourable for non mesocyclonic tornadoes. However there is no area of convergent low level winds forecast to provide a source of vorticity so these are unlikely. Outflow boundaries are only likely to cause convergence at the back edge of storms and without back building storms are equally unlikely to play much part today.

    So we wait and see how things develop for today.

    Slight differences in the models for tomorrow on where the trough will cross the UK. UKMO suggesting it will cross the south east corner of the UK while GFS suggest more of a blooming north and eastwards from central southern areas.

    This is likely to be a confusing picture tomorrow with the occluded frontal boundary and trough likely to be close together. There might be some instability and wind shear values look capable of giving low topped mesocyclones. The most likely outcome is that cloud tops will be too low for thunderstorms and instability in the boundary layer will not be enough for any risk of tornadoes. Steerage winds would tend to sugegst any storms firing over norther France are likely to head north and with supercells possibly forming there then some severe weather is possible. The highest risk tomorrow seems to be for high rainfall amounts as storms become outflow dominant over the UK. More tomorrow when the picture becoems a little clearer.

    Low level convergence forecast across the central UK late afternoon tomorrow which may provide some extra focus for storm development.

    Forecast SkewT for Stoke suggests some low level directional shear just north of the convergence zone. Some good lower atmosphere speed shear as well. However surface temperatures are held back and instability is elevated.

    Looking at a number of forecast SkewT's suggests there may be a chance of some surface based storms but we will not know untill tomorrow how accurate they are.

    Plume of high theta-W (wet-bulb potential temp) values advects NNE out of France this afternoon/evening across Sern England,

    post-1052-1182237775_thumb.png

    00z Bordeaux sounding suggested an elevated warm moist plume around 700-800mb was overspread by steep mid/upper level laspe rates, storms broke out here over night.

    post-1052-1182238089_thumb.png

    This airmass representing the plume with instability aloft is likely to move NNE towards the UK and be subject to surface heating over Nern France with storms reactivating and heading towards Sern England this evening ... lift from an occlusion and also upper/mid level troughing arriving from the SW this afternoon will also likely destabilise the axis of the warm moist plume, PVA at the exit of jet streak moving North out of France will also help lift.

    Troughs at 500 and 300mb arriving from SW this evening will promote strong synoptic lift:

    post-1052-1182238060_thumb.pngpost-1052-1182238049_thumb.png

    00z GFS suggest a band of heavy rain with thunderstorms crossing England and Wales this evening, possible MCS for Kent/E Sussex moving up from France later this evening:

    post-1052-1182238204_thumb.pngpost-1052-1182238212_thumb.png

    Severe potential exists over central-S and SE England if storms can root into the boundary layer (become surface based), 0-6km deep layer shear of 40-50knts is indicated with a strong jet streak moving North out of France this evening - so bowing multicells and perhaps mesocyclones/supercells are possible with any surface-based storms, also 0-1km low level veering of winds with strong helicity is indicated - so potential exists for tornadoes in surface based storms:

    Winds this evening - 300mb shows strong jet arriving from France:

    post-1052-1182238576_thumb.png

    Lightning wizard shows strong 0-6km and 0-1km shear, also STPs (significant tornado paramters) and strong storm relative helicity for Sern England this evening:

    post-1052-1182238651_thumb.pngpost-1052-1182238660_thumb.png

    It is uncertain whether storms may become sfc based however, if storm remain elevated, there is still the chance of strong straight-line winds and the threat of hail and heavy downpours.

    Three seperate areas to be interested in.

    1) Wales and Northern Ireland with heavy rain and embedded storms and possibly super cells.

    2) MCS with possibly super cells forming over northern France and moving north across the south east late in the day probably slightly elevated.

    3) Possible surface based storms central southern England late afternoon.

    Main risk would be heavy rain ,gusting winds and some hail.

    Tornado risk is quite high with Estofex suggesting moderate risk of severe weather for parts of the southern UK.

    Estofex forecast

    Forecast SkewT for Oxford looks to have a moderate Tornado risk, but this does look reliant on surface heating ahead of any storms.

    Some good potential in the South East for something pretty severe between this evening, with the possibility of imported MCS storms from France. An area of warm, humid, unstable area with a pronounced area of vorticity is moving North from France.

    A convergence zone in France getting close to SE.

    An eddy forming too.

    A very are of vertical velocity also over the SE.

    Here is the rain flirting over Kent.

    Across the rest of the country, a band of heavy thundery rain will move NE across the UK later this afternoon and evening. It should mainly be rain but there should be some thunderstorms mixed in as well. The best areas for storms could, shockingly, be South and mid Wales.

    Here is my storm risk map for today.

    Moist SWerly flow over much of the UK today will be over spread by increasingly colder air aloft from the West due to the presence of an upper low/cold pool to the West - which will swing upper troughs NE/E across the UK today, this is likely to steepen lapse rates sufficiently for convection to be triggered by surface heating of the moist sfc air, upper troughs will likely aid lift.

    post-1052-1182324436_thumb.pngpost-1052-1182324414_thumb.png

    00z Camborne ascent suggests a moist boundary layer with only weak capping likely to be overcome by surface heating to 18-19C (today's likely maxes in the West) which will steepen lapse rates and create a few hundred j/kg of CAPE, so convection should readily occur in the West this afternoon. Cloud tops suggested to 300mb with a convective temp of 18C, so thunderstorms could develop over Western and Central areas if the airmass is unlikely to alter too much.

    post-1052-1182324728_thumb.png

    GFS indicating highest CAPE values over Nern England and Sern Scotland this afternoon ... though Wales and the Midlands are likely to see heavy showers with thunder too:

    post-1052-1182324721_thumb.png

    Most likely areas to escape with a dry day are SE England and parts of East Anglia:

    post-1052-1182325020_thumb.png

    0-6km deep layer shear looks fairly weak in the West - so showers/storms should be well scattered and pulse type, though GFS suggests some moderate low-level shear - so funnels are a possibility again.

    Prime area for storms today looks to be northern England.

    Expect some subtle changes on the 06Z output though as the upper level trough is slightly off from where it is predicted to be.

    Some moderate low level speed shear will provide a source of horizontal vorticity but unidirectional upper winds suggests mesocylones are unlikely to form. Where we get seperation of updraft and downdraft tornadoes are thoretically possible although

    low level winds look a little strong, so I think there is almost no risk of tornadoes today.

    Keep an eye on the south west and southern wales for the early hours of the morning tomorrow where some heavy rain and strongly gusting codnitions are expected.Trough moving north should also spark of a few storms during the day again some wind speed shear but no directional shear.

    Slack winds on Friday with some high instability could give conditions favourable for some non mesocyclonic short lived funnels.

    Moist Serly flow still covers much of the UK today, upper and collocated sfc low situated over Sern Ireland with rotating upper troughs swing North across the Western side of the UK and occluded front moving Eastwards across the SW are likely to be the focus of shower development this afternoon, orographic lift over the mountains of Nern England and Wales likely to play a role in convective development aswell:

    Surface and upper charts for 1200 today:

    post-1052-1182409565_thumb.jpgpost-1052-1182409576_thumb.png

    Upper trough and occluded front already bringing showery rain across SW England and Wales, upper trough is expected to eject NNE across Wales towards NW England this afternoon steepening lapse rates and creating lift ahead of it, while occluded front moves Eastwards, heavy showers look to develop across the West and North of England, Wales and parts of Scotland where greatest instability is progged, these showers developing further East across Central and perhaps Eastern areas this evening - driest towards the SE of England. Moist forecast skew-t profiles suggest heavy downpours are likely and with slow moving showers likely - some localised flooding is possible.

    post-1052-1182410419_thumb.pngpost-1052-1182410427_thumb.png

    Little 0-6km speed or directional shear available aloft with the jet stream way South over France today - so poorly organised non-severe and short-lived pulse-type cells are most likely. Some surface convergence of winds over SW England and S Wales is possible which may create enough LL vorticity to stretch stronger updrafts into short-lived funnels.

    Tonight into tomorrow morning, occluded front moving East across Sern England may see heavy thundery rain pulsing NE out of France along its axis across SEern England, though atm it doesn't look to be particularly electrically active - but one to monitor.

    Tomorrow, sfc low sat over Sern England overlayed by cold pool aloft at 500mb, and with light variable winds converging warm moist surface heated air towards the low likely to lead to some slow moving heavy downpours with thunder over much of England and Wales - with risk of localised flooding, some uncertainty to the positioning of the low though, GFS has it over Central England while UKMO has it over Sern counties:

    post-1052-1182410879_thumb.pngpost-1052-1182410890_thumb.png

    Highest CAPE and LI towards South-central England:

    post-1052-1182411045_thumb.png

    Very little 0-6 km speed or directional wind shear again with absence of the jet stream aloft, however, light winds and wind convergence may create funnels with any strong updrafts.

    This what I think will happen. There doesn't seem to be much in place for widespread severe storms, nothing like the day before anyway. Not much cape about apart from some in SW and across Scotland and N. England .Mostly heavy showers with some thunderstorms mixed in I think. Tomorrow looks a lot more interesting however.

    GFS 18z progs a very interesting setup for much of England, Wales (and for a time) N.Ireland. Slack low centred over the UK with variable mid-level circulations across the country...with a SE-NE veering flow for central and south-east England with the 500mb flow more N-NW for northern England and Ireland. The variable circulation will mean the lack of a consistent steering flow for convective showers that do develop over much of the favoured areas...with the flow governed primarily by the vorticity from an amplified jet-streak arcing around a Greenland ridge and a small feature over southern England associated with the upper flow across northern France which intensifies in the evening, before gradually filling and merging with the upper trough to the east.

    GFS progs a low-level convergence zone developing across part of south-east England and over much of western Britain in the afternoon, which will help act as a triggering mechanism - albeit with perhaps aid needed from solar heating if certain areas contain too much mid-level cloud which may act as a bit of a warm-layer CAP preventing pockets to 'punch' through on convergence uplift alone. Solar heating may well benefit parcel buoyancy in areas of sufficient boundary-layer moisture which seems abundant particularly across central and western areas. Here's hoping that cloud isn't too extensive and thus convection can realise its potential.

    Lapse rates generally suggest t-storm spawning potential with many places showing a moist convective profile and lapse rates over 25C. As the day progresses towards the evening...the low-level convergence zone edges slightly eastward...thus perhaps extending the convective risk for areas further east such as Yorkshire, Lincolnshire and North-East England. Too strong a sea-breeze however may blow in low cloud which may act as an inhibitor for coastal areas, but this seems rather a low likelihood factor for areas south of the borders (which are within the low circulation). Prime risk areas are central, northern and western UK...with the risk transferring further south and east through the day. As has already been pointed out...dynamic rainfall in the early hours is likely to delay or limit convection if cloud lingers for too long. The volatility of mid-level steering winds are also a factor likely to influence the organisation and distribution of showers.

    Just want to add that the chances of supercells and tornado's are somewhat low due to a weak upper flow over England and Wales...hence limiting convection-enhancing horizontal shear and tornadogenesis and punctuated mesoscale squall lines. Veering wind profile in the vertical also seems rather lacking.

    Nick F and the likes will likely elaborate on this later today as the latest runs come through.

    A rather moist airmass persists across the UK today. 00z Camborne ascent shows a moist profile in the lower tropsphere, steeping lapse rates aloft with upper cold pool overspreading, however, a weakly sheared environment in which convection will take place:

    post-1052-1182496618_thumb.png

    Low pressure aloft and at the surface and upper cold pooling will freely allow uncapped convection today over many areas of the UK, surface heating maybe an issue over England initially with alot of cloud around thanks to an area of rain moving North across Southern and Central areas early this morning along a wrap around occlusion. However, GFS suggests wind convergence across the South towards the centre of the low expected over Central Southern and later Ern England and also an area of wind convergence running South across the West will likely initiate convection:

    post-1052-1182496700_thumb.pngpost-1052-1182496717_thumb.jpg

    Where breaks finally appear in the cloud over England (already sunny breaks across parts of Sern England), insolation should help increase CAPE of the moist air to several 100 j/kg, 00z Camborne ascent suggests cloud tops reaching between 300-350mb with a convective temp of 18C - so thunderstorms are likely. With such a weakly sheared environment with little strength to upper winds, showers are likely to be slow moving - and with such a moist atmosphere, heavy downpours with excessive rainfall totals in a short space of time over one area will bring the risk of flash flooding to some places.

    With weak wind shear, scattered single cell pulse type storms are most likely with little organisation of convection, hail looks unlikely given the moist profiles up through the troposphere (ideally dry upper air needs to be present fort hail). Howevere, with Low LCLs (Camborne ascent suggested an LCL of only 550m) and low-level wind convegrence creating vorticity, any strong updrafts maybe stretched into funnel clouds today.

    Anywhere really across England, Wales, South and central Scotland in with a chance of a heavy downpour with thunder.

    06z gives less cape for the south. Still good chances in most places of the UK today for a storm. Slack winds from the low pressure means that any storms will be slow moving giving the likely hood of some localised flooding. A small convergence zone over the South could help trigger some severe slow moving cells, so something to look out for.

    Here is my forecast map for today.

    The focus for any storms today seems likely to be a low level convergence forming over Wales and the north west.

    Forecast SkewT's show fairly light winds with some veering at lowere levels.

    Some warmth is forecast above 500hPa although eumetsat satellite pictures show some cool dry stratospheric air being pulled down. This could limit cloud tops with an upper jet stretching out any anvils that form.

    Some slight risk of non mesocyclonic funnels forming (weak short lived) although low level lapse rates are not that impressive so updrafts could be a little too weak.

    Some very heavy rain across central and north parts is expected tomorrow ,so keep any eye on weather warning for tomorrow where some flooding seems possible.
