temp back up to 21C but RH is 73% with a dew point of 16C so feeling quite humid which is good news in fact it feels more humid after it has rained so fingers crossed its a good omen for later on!

Yeah ive been thinking it  would feel more humid after any rain as the water from the wet ground evaporates so then the air above the surface has more moisture.

Day 1 Convective Outlook

VALID 06:00 UTC Sat 21 Apr 2018 - 05:59 UTC Sun 22 Apr 2018

ISSUED 13:55 UTC Sat 21 Apr 2018

ISSUED BY: Dan

UPDATE 13:55 UTC MDT shrunk in size over N England, while MDT added to English Channel and adjacent counties of southern England / Channel Islands.
Mid-level cloud and showery bursts of rain continue to drift north across the Midlands this afternoon. While an elevated thunderstorm is possible from this area of mid-level instability, coverage is not anticipated to be widespread enough for a MDT for now.

Surface observations suggest low-level wind convergence is beginning to develop over N Wales, and should continue to strengthen this afternoon, while expanding into NW England. This combined with increased forcing aloft should allow a few surface-based thunderstorms to initiate from about 17-18z onwards, initial focus over N Wales and then gradually shifting NE-wards across northern England during the evening hours. Particular focus is given to the western half of this MDT area.

An increase in coverage of elevated thunderstorms seems possible late afternoon and into the evening over the English Channel, drifting NE into portions of southern England. Some uncertainty as to how widespread this activity will be, with some suggestions it may begin to decay as it approaches the M4 corridor, hence limiting the northern extent of the MDT for now. Other elevated thunderstorms may develop elsewhere over the Midlands and East Anglia this evening/overnight in a rather sporadic fashion, perhaps even as far north as E Scotland

This is brilliant for NW England.

steering flow is moving cloud/showers etc on an increasingly NE trajectory as opposed to a more northerly movement earlier today......not great for the west country it has to be said

and as if by magic and just to prove that the numpty known as 'ajpoolshark' needs to learn more, sferics detected over the brest peninsular heading for....yes, you've guessed it....the west country.....lololol

Some very rapid intensification in North France as lightning maps are showing new sferics, east of the main bunch but only still a light shower on the radar

 22.6°C. The sun is beating down relentlessly. Hard to believe it’s only April.

A lot of storms now erupting over Northern France and the Channel. A wedge of moderate convective rainfall heading for me and some intensification of the showers moving through Wiltshire. No precipitation at all yet across Wales or NW England, but still plenty of time.

If things edge too Far East tonight, I might have to make my first storm chasing trip ever! Very promising

Getting ultra humid here but little sun getting through the cloud so elevated storms probably won’t root in our parts.

either way I must say I’m excited about our prospects now the channel’s got going :):bomb:
