Good luck all,:good: It certainly looks promising.:) TORRO now have a tornado watch. Keep safe mateys if anything happens your way:)

TORNADO WATCH 2010/005

A TORRO TORNADO WATCH has been issued at 0700GMT on Friday 20th August 2010

Valid from/until: 07:00- 20:00GMT on Friday 20th August 2010 for the following regions

Parts of (see map)

Wales

Much of England

Northern Scotland

THREATS

Tornadoes; wind gusts to 65mph; CG lightning; heavy rain

DISCUSSION

Reference TW004 below for main synoptic overview. Short-wave trough is moving towards SW Wales. Strong ascent ahead of this has allowed thunderstorms to develop from the moisture plume. Although these may be slightly elevated some surface based activity is likely. Tornadoes are possible, perhaps strong, along with severe wind gusts as it moved north-east. Further activity may then develop from the shallow moist zone, if spells of sunshine can develop. Again, severe winds and isolated tornadoes are possible.

TORNADO WATCH 2010/004

A TORRO TORNADO WATCH has been issued at 2315GMT on Thursday 19th August 2010

Valid from/until: 23:15- 08:00GMT on Thursday 19th/Friday 20th August 2010 for the following regions

Parts of (see map)

Eire

N Ireland

S Scotland

Isle of Man

THREATS

Tornadoes; wind gusts to 65mph; CG lightning; heavy rain

DISCUSSION

Strong upper low is moving NE to the west of the British Isles, with an associated short-wave crossing the watch area. A broad, very moist tropical maritime airmass exists at low levels, behind a warm front, which is currently moving through Scotland. A cold front to the west of Eire/N Ireland will start to move eastwards later tonight, and tend to surge eastwards later. Instability exists in the warm sector, partially aided by mid-level cooling associated with the upper trough. Thunderstorms are occurring already across SW Eire, and further showers and a few thunderstorms are likely overnight. Strong deep layer shear (40-50 knots) should promote cell organisation, perhaps supercells. Low-level shear of 25-30 knots suggests low-level mesocyclones are possible. Tornadoes and damaging winds are possible across the area, and the magnitude of the low-level shear coupled with a very moist boundary layer suggests a small chance of a stronger tornado.

The risk will extend into Scotland through tomorrow morning, and a new watch is likely to be needed tomorrow morning.

Oh dear, this is looking rubbish for the SE...never mind, least we can enjoy the moist warm air flow, which is in stark contrast to the chill/very cool air flow of the past fortnight!!

Some heavy rain in NW England heading to the NE, looks like a few sferics in it. Hope the Pennines don't kill it though, already it seems to be losing intensity.

Also no sun here this morning, I would have felt much more confident had it been sunny here.

Still I'll enjoy watching, waiting and hoping :rolleyes:

Sod heavy rain, have you seen how rapidly the two main areas of heavy/torrential rain intensified between 0830 and 0900 this morning? :D:rolleyes:

Morning all. To answer Andys question from the previous thread, no I didnt hear any thunder last night, although the rain here was quite impressive for a time. Was quite gusty too, a tall bush in our garden seems to have been uprooted.

Nice to see a fair amount of electrical activity showing up already, though I better not get my hopes up too much.

Oh joy, the fairly unreliable met tabular forecasts have got the thunder graphic for Saturday night for me.

I see that as well but put little stock in it as they had the light rain graphic last night and the rain was anything but light

anyway that's 36 hours away and the weather forecasts seem to be changing constantly

Well the BBC is usually almost identical to the met, and for some reason they dont seem to want to mention storms very much, and are frequently rather late with warnings about this stuff.

Completely agree that the table-based met forecasts arent exactly the best guide to the unfolding reality, they are slow to change them and Im not sure what their methodology for these forecasts is but its often less accurate than their own 'invent' maps.

South Wales seems to be enjoying some sferics, anybody down there confirm what they are getting? :rolleyes:
