1 Killed in Manchester as 2 lorries collided on the M6. BBC reporting that the emergency services are now only being dispatched in the Manchester region as a "last resort" due to the demand and severity of the road conditions.

The Derby will depend on a decision by GMP and Manchester City Council. If the Stadium Safety Manager has any concern for the welfare of fans both inside and outside the ground, the game will be called off. Its more than just a fan safety concern but also staff liasoning, and ensuring in the event the bad weather does continue there wont be 70k fans stuck in Central Manchester unable to get home. With more bad weather to come this afternoon I have my doubts this game will be going ahead.

Just been thinking the same myself, what with 70,000 fans travelling from all parts (including the south lol), If Manchester Airport is disrupted due to this Snow with the clearing equipment they have, im sure COMs must be having serious concerns about tomorrows game.

Morning all. Woke up to find some 10cm topping up of what Snowfall we already had here on the Snowfields of Derbyshire. Looks like the LP is beginning its wrap-around as HotCuppa mentioned, the RADAR suggests this is the case which means more snow banding to come aswell as further activity for the NW for the coming hours into the Afternoon. Stockport College is shut im informed aswell as many of the schools locally here in the Peak District.

People were reporting Sleet/Rain before in coastal areas as a tongue of warmer air was mixed in along with the Convective Inhibition which was causing the Streamer to form, this in turn approached towards the NW Coasts and fell as Sleet/Rain (Snow further inland where nocturnal temps are lower.) The Frontal system is already undercutting this Warm sector, as the airmass behind the Front is completely Arctic. No worries about any rogue Warm Sectors coming from that region lol. Once the Front hits it'll be Snow completely.

Definitely a night to remember. 2x Snow events meeting up slap-bang over the centre of the Northwest. With the Streamer now being dissipated from the Irish Sea (the last of the PPN being carries SE along with the Wind Vectors.) This ties in well with the fact the BBC was only giving Showers to Eastern parts of the NW for the main Frontal event today. However now its gathering pace and has ample moisture to pick up over the Irish Sea, anywhere in the NW will be seeing a significant snow event. I was hoping this Streamer could eventually be cut off by the Upper Vectors as this means more CAPE ahead of the main Front.

Sorry just been watching TN video's on Youtube. The South of the region will see Snowfall into the morning as the Front makes its way through, BBC wants to keep the main area of PPN to the East with bands of showers in the Cheshire Plain. Lower Levels I'd hazard a guess (and its only that for now) of around 5-10cm (including drifting) around Northwich, Warrington etc. On the Pennine tops, the Snow-Depth will be topped-up double to what it already is now so another 10-15cm, giving a total depth of 30cm on the higher passes such as Snake Pass and the Cat+Fiddle Road.

Given the METARs it seems the Sleet/snow coastal areas have seen will readily turn to snow as cold pooling from the Northern Front overlaps the warm segment of the Streamer, until the showers are finally embedded within the front itself. Liverpool seem to favour the fact the Streamer will gradually turn more showery, but falling as Snow whereas Manchester are basing the METAR solely on the Frontal system coming in from the N.Pennines now. Its worth keeping a eye out on the Manchester (EGCC) future METAR reports for any possible Polar Low/Sferic activity that may be predicted throughout tomorrow.

Seems John Lennon/Liverpool Airport disagree's with you. latest METAR EGGP 042302Z 0500/0524 28010KT 9999 SCT010 TEMPO 0500/0509 5000 -RASN BKN010 PROB40 TEMPO 0500/0509 2500 SHSN BKN006 TEMPO 0509/0520 5000 -SHSN BKN010 Manchester also reporting Snow.

Anywhere thats more than 3 miles inland from the Irish Sea is currently getting pasted by this streamer setup. With yet more cells building out to the NW of the stream. Im not surprised some places North of Liverpool and Warrington are seeing some of the accumulations they are. And to think the main Frontal Snow-event is due for another few hours for the entire NW yet. Anyone who's not seeing Snow from this Streamer Setup, dont be too disappointed as its only just the first 3 hours of a 48+hour event.

Light snow here for the past hour and a half, but its been persistant so that will add problems already to road closures and lack of Road Salt. A nice large shower (possibly due to forcing ahead of the main front) developing over the North Pennines, could just clip the Peak District on its way down, aswell as this possible Polar Low coming SW from the Shetland Isles.

Its now official that the Buxton/Chapel Gritting Depots have run out of Rock Salt to lay onto any of the Surfaces overnight. Traffic will be absolutely horrendous tomorrow morning, for anyone brave enough venturing out.

Minima figures for Buxton overnight are -10'c by Midnight with it still remaining that way even until 9am tomorrow morning. Here in Whaley Bridge were expected -9'c throughout the night with the temps posing a problem for commuters and the school-run up until 9am also with temps barely recovering until Midday tomorrow. Gritting Depots around here are on their last reserves or run out altogether, Footpaths are barely walkable on (even with Mountain Boots) and I dread to think of those using the higher passes in the morning, even the main roads have barely been gritted. And those that have are now literally ice.

I hate to brag, but complete white surfaces here..after the other lot in December melted away, the hills have started to see shades of Green come back on the fields, now everything is covered in a nice white again. Heavy Snow aswell with some big flakes for the past hour.

Some info for those who cant access the .pdf document. Maximum Partial Eclipse due at 7.22pm, just entered the first stage now. http://en.wikipedia.org/wiki/December_2009_lunar_eclipse#Map

Still some patches of Snow here and there on the hills, but melting considerably faster with this milder airmass overhead. Just had a shower of Sleet however as a Occluded front passes the region lowering the Freezing Level. MetO and Beeb seem to think some 5-10cm will fall over the Pennines on Tuesday morning as the Warm Front "bumps" into Cooler Air being fed down from the North, only some 48 hours to find out now.

Funnily enough Ive been sat in just my T-shirt and Woolen Trousers since the Front passed, despite having my window open aswell.

The Low thats out to the SW of Wales is progged to move north up into the Central Irish Sea overnight, giving the bands of Showers coming into the SW Wales to move even further Northwards towards our region in the early hours and into tomorrow afternoon. This Occluded Fronts energy is being dispersed by regioning across the North Sea to Scandinavia from the recent charts, so it was always going to be a clear-cut thing anyway as to how much precip we was going to get. It was just a case of "where", not how much was due to fall. This next event with the Low in the Irish Sea should set up a few good showers and possible Streamers given that Wales has had plenty of low overnight minimas, and little "lake effect" temperatures to scupper any showers turning into rain.

Goes to show how the Cold Pooling is influencing our weather at the moment, even with this warm sector. The South between Portsmouth and Bournemouth, where the Occluded front is Passing by, are seeing Lightning every 90 seconds, with Southampton reporting Hail in places 2cm's deep.

More precip coming into the Welsh SW Coast *could* have our name on it, if it manages to survive the long trek across the Welsh countryside past into Stoke. A long shot but something worth watching for later on after the main Front has cleared.

Looking great for us Northerners as the Front moves ever Further North. Undercutting the Cold air and Evapourative Cooling is bringing temps down underneath this Front, meaning almost anywhere ahead of where the Front currently is now will see Snow.

The good news is the Precip band is turning to Sleet already on its Northern Edge as it begins to hit the Cold air, further south than the Beeb were forecasting it to be. Which means the Cold Pooling will be already underway and places even further south than than Northwest could be seeing some of the Wintry stuff soon.

Charts have the feature 50/50 over the region. With a Cold Front the further West you are and a Warm front the further East. MetO brings the sector into a Occluded front passing into the Pennine region however overnight, levelling out the temperatures. It'll just be a case of hoping the Warm Sector doesnt influence the the region too much.

MetO Surface Pressure Forecast brings a trough over the region at 00z tonight, with another Weds into Thurs (which should have been a Warm Front but now predicted to be a Convective feature moving Northwards instead.) Predicted Snowfall Forecasts estimate another max of 5cms with these features ontop of what we already have, although confined to areas over 250m ASL. Lower areas of Chehire and the Coast who have already seen some slight Snowfall will be missing out on these 2 Convective events.

Sounds like a localised convergence zone, or possible a area of Forced Uplift taking places around the Inflow/Outflow boundary of the cells your Under.
