What Would Be Your Rating?
Monday 1st June:
Scattered showers and T-storms will develop through the afternoon and evening, particularly across S England where instability is expected to be greatest.
Storms may become organised for a time bringing frequent lightning, these storms will mostly be sporadic.
Models are suggesting daytime heating combined with colder air aloft will allow showers to develop, with some becoming thundery during the afternoon. Frequent lightning, torrential downpours, localised flooding and small hail may accompany the strongest cells.
Eyes On Tuesday!
Saturday 30th May:
Heavy showers are expected to spread NE through the day, with scattered T-storms possible, particularly across N / NE Ireland. The strongest cells may produce frequent lightning, torrential downpours, small hail and gusty winds.
Update following...
Latest high-resolution guidance show a very unstable airmass developing across parts of central and eastern England this afternoon, with CAPE values exceeding *2000β3000 J/kg*
Any strong T-storm could evolve into a Supercell today... β‘οΈ
However, due to uncertainty surrounding storm initiation, overall thunderstorm coverage is expected to remain local at best. Any storm that does form may strengthen rapidly and become locally severe.
This could be one of the severest storms ive seen in my life, not so much in the way of lightning but rain rates / hail size...
β’ Frequent Sheet Lightning
β’ Explosive Development All Under 30 Minutes
β’ Large Hail

Insane stuff.
UKV 21z is now in a similar scenario for whats currently ongoing across Wales / Midlands.
Still seeing the precipitation being much extensive and stronger, however the UKV has this dieing out slowly as it heads S.
Eyes on whether this dies or continues!
This feature comparing to the models at 2100 looks more extensive and definitely more intenser then previously anticipated from the models.
This has increased the chances of snow for lowland areas of south / se areas.
Being 12 hours out from this feature tracking across England down into S England.
Exactly the intensity / extent & track of this feature is still fairly uncertain. This is becoming a nowcast event, alot of suprises incoming!
A very active rare cold front is going to be tracking from NW Wales down CS/SW England early hours of Friday bringing a mixture of sleet & snow.
Snow will likely accumulate on higher levels with potentially a dusting on lower levels depending on how fast the cold air undercuts.
Merry Christmas to everyone celebrating, enjoy the times with your families! βοΈ
As of a Christmas present to everyone, after a long break we are officially back!
Interesting situation today and tonight across the U.K., especially during the night over England with fast moving storms having a potential to produce severe wind gusts and tornadoes. Once again, the low level stability will be important.
