Load of sferics popping up north of Manchester and quite a few storm reports around the NW of England. Looks like this could be an active day for some storm starved peeps!

I'm hoping the sun will come out later for our BBQ!

Convective / Storm forecast - Issued 06/08/2011 11:00



Valid: 06/08/2011 11:00 - 07/08/2011 06:00
Headline: ...THERE IS A RISK OF THUNDERSTORMS FORECAST...

Synopsis
A large upper low to the W of the UK is driving a deeply cyclonic SW flow across the UK, unstable across Nern and Wern areas. At 12z Sat, an area of low pressure is expected to develop over N England, drifting N to be near SE Scotland by 00z, further south sets of troughs will move east across Ireland, England and Wales.

... N ENGLAND, WALES, MIDLANDS, SW ENGLAND ...

Devloping low over N England this morning, in the left exit of SW'erly jet is producing clusters of thunderstorms already this morning over parts of N England - as moist maritime airmass is forced to rise. Storms may continue across parts of N England this afternoon - 30-40 knts of vertical shear for a time will lead to some organisation of storms bringing a risk of localised flooding, hail and gusty winds. Models also indicate that instability/CAPE will extend further SW across parts of the Midlands, Wales and SW England this afternoon - as lapse rates steepen from the west and brighter skies lead to insolation - so scattered heavy showers and a few thunderstorms are likely here too.

... IRELAND/N IRELAND ...

Upper low with its associated colder air alot will overspread Eire this afternoon - with airmass characterised by steep low-level lapse rates - this will lead to scattered heavy showers and some thunderstorms to develop aided by insolation. Vertical shear will be fairly weak, so no severe weather is anticipated, though storms maybe accompanied by hail, gusty winds and torrential rain.

Im glad to see im in the risk zone for a change today! Though it is cloudy at the moment, I really hope to see something as in the last 2 years I have not had anything more than a few flashes and rumbles! Looking good though for today, good luck everyone

Meto also say this for wales tomorrow:


Sunday:
Showers throughout the day, these heavy and thundery at times. Chance of more persistent rain in west and southwest parts for a time. Remaining windy. Maximum temperature 19 °C.




Also glad to see they have a *Thunderstorm* symbol for my location, which I thought I would never see lol

No heavy rain at all yet in Darlington, we've had rain but it's dry at the moment.

I think those wanting these storms today will be counting their blessings they didn't see any, given the axis this SSL is going to take in the next 12hr, pivoting around Cumbria and stalling practically to near where it is now. Were going to see many households, businesses and the like being flooded (with reports of this already happening) so now is a case of warning those in a floodwatch area to start moving things to a higher level, if only for precautionary reasons. Because this has chaos written all over it.

[Chris K]

Still plenty of the day left, but i don't like it how the showers heading my way from the SW are weakening as they approach Cornwall & Devon. Hopefully things start to kick off later. Skys are clearing here now after a greyish morning and now bubbly cumulus clouds are forming.

Also agree with Snow_Joke though...there is potential for a lot of flooding in some areas which isn't good.
