Convective / Storm Chat And Discussion

[Coast]

Please continue the convective storm discussion here

Nothing in the coastal areas of Sussex all day except strong winds. Ah well, the charts didn't really point to us getting it, but I am getting storm starved!!!

[snow raven]

Just heard a couple of very distant rumbles of thunder here - still trying to work out from which direction it's coming from.

[lewisosd]

Got some nice pics of the front of that cell from Cambridge way.Few rumbles but no lightning. Rain was coming down in buckets!

Well I have to say given the promising forecasts earlier, things down here on this part of the south coast ( Hastings ) have been a huge dissapointment.. Im not one of those people who expect a storm right on my doorstep, so I drove a fair bit today, and all I saw was........erm....a few clouds.

[Stormyking]

At about 8am this moring there was a thundery shower that passed to the south of us, didnt hit us but could hear the thunder even though i was half asleep could still hear it easily

[TornadoJo]

Thunder - Again.

[Mike Storm]

yeah I heard that too, been missing out all day by a mile or two as the cells have passed to my north

[Buckster76]

not a great day convective wise

no lightning here

no photogenic tops:(

felt too fresh and cool to me - I reckon the early rain kept the temps lower than they could have been

roll on proper summer

[Wet'n'Dry]

That's my 2nd storm today, just passed through with 1 CG and heavy rain. Still pouring with what looks like more to come

[Flash Elvis]

I can hear thunder but cannot see lightening grrrr

Could this be my 1st Storm of the year???

[Neilsouth]

Thunderstorm seems to be moving up the estuary!, looks very good from here and also another well built anvil to my south

[Mesoscale]

had a very very long rumble of thunder this morning. and there was to more rumbles of thunder at about half 4 this afternoon. its like a tap that keeps turning on.

[Typhoon Turner]

cracking short sharp downpour and three close C to G strikes nr Chislehurst, Kent this afternoon.. impressive cloud structures and a serious gust front too... shame no camera handy

[Evening thunder]

Not much here today really, Most of the showers either missed me or developed just to the east of here. Not especially good convective skies either with it being mainly cloudy and breezy.

[Stuart]

Areas Affected:

Southern Scotland, Northern Ireland, North and Eastern England

Discussion:

Cold air aloft, 500mb temperatures of around -22C, will allow for unstable air and the potential for a few thunderstorms. An old occluded frontal boundary will help to provide moisture and and a little extra lift to help generate showers during the morning, some of which may become thundery. A small amount of CAPE (values of 200-300j/kg) and very little wind shear should mean these storms will likely only produce a small amount of thunder and perhaps some small (less than 1cm) hail.

Any thoughts regarding Monday? Looks like some potential for the Midlands with some Cape, Good DLS etc however looking at the precip charts it seems more like a frontal band of rain rather than showers hence me thinking more that thundery weather is perhaps unlikely as to me embedded Thunderstorms in frontal precip rarely seems to occur.

saturday - one intense downpour from the London storm around 1-2pm then some incredible anvils and bubbles through the day with one especially amazing towards the northwest horizon around 4-5pm anvil on that was just one of the best ive seen!!

[NO LONGER POSTING]

What is that massive area of rain of the coast of Cornwall?? Looks very intense and there is a mass of cloud out there too...

[knocker]

The 0600z chart probably answers your question. Currently here we have 8/8 Ac, As with some Sc and small Cu below. The Camborne Midnight is very stable as expected.

[Nick F]

The rain SW of Cornwall appears to be falling along upper warm front shown on 0600hrs fax this morning:

... this is part of the frontal system ahead of next low pressure system queuing up to the SW of Ireland - which will spread rain north and east across England and Wales tomorrow.

On to today, might see a few storms across S and E Scotland, NE England and perhaps as far south as E Anglia today, see the storm forecast for today: http://www.netweather.tv/index.cgi?action=convective;sess=d74bf3d682b8427b5208094566c2e79e

Maybe later in the week?

Mind you, the way this year is going, we may get a brief shower and nought else!

ESTOFEX showing a similar area in their update:

[Dom W]

Raining heavily in Shotton some rather large drops too

[Neilsouth]

Bloody rain , we weren't even under drought conditions in this part of kent

[Staffordshire]

Looks like most of central England and Wales could be in the firing line for some good thundery activity, what are you're views?

[Costa Del Fal]

NMM keen on a small area of thundery potential for the Midlands and perhaps Wales tomorrow with very decent Deep Layer Shear too. GFS also shows some instability. Been quite quiet around here recently so any interest would be good however i feel tomorrow will not produce anything more than a band of rain.
