Was in the centre of Norwich 15 minutes ago, the skies were darker. Needed to travel to the Northwest side and on the way I thought a water mains had broken. From dry to soaked within metres lol it had already moved away.

Ah yes I remember that frustration well. As if the weather in the southeast wasn't boring enough already, Egham always seemed to pull the short straw when it came to storms.

I had a feeling looking at the charts this morning the potential would take a leap across the sea in an easterly direction. Estofex didn't forecast anything today.

Speaking of this morning we did get some reasonable mammatis on the back end of a shower that passed through.

Can't help but dread thinking I will miss a real decent event. I'll be stuck in wales next week when the likes of Lincolnshire right next to me will get a dosage of supercells! Wouldn't it just be typical!!

Haha yep, although we had a couple surprise thunder events this winter. The ones today lost their electrical activity quite quickly so it wasn't so bad but most of the heavier showers and downpours still missed here.

Yet if you read the summary on BBC News there is no mention of rain in this area!

The weather has been dry and mild across much of the UK, with isolated showers in some parts of the north of England.

There's definately an increasing sign of a possible Spanish plume development on Tuesday. We have an area of low pressure in the Atlantic pumping up warm air and moisture from Southern Europe.

Because of this, the CAPE rises and the air becomes increasingly unstable. The warm 850s also cause the lapse rates to rise, which is the perfect recipe for thunderstorms.

Best example was May 22nd last year. Big batch of shower and storms rattled northwards across the country - my home location recorded a thunderstorm, Heathrow recorded thunder and apparently Thorpe Park got hammered. Not even a fart in Egham haha.

 

At least you'll be in a sweet spot for some proper warmth come early next week.

Dare I say it the central lowlands looks to be in the firing line. Interesting..........................

Wouldn't surprise me to see a bit of electrical activity from that rain moving up, from the south, through tomorrow. Slight instability and clearly a lot of moisture there, too.

There could be something interesting brewing for the late afternoon and evening hours I feel. GFS are showing an area of slight CAPE but strong DLS and some helicity through Wales, N Midlands and N England late afternoon and more especially this evening. This would point to the "potential" of thunderstorms developing across Wales and NW England, pushing NE into the N Midlands and N England then eventually Lincolnshire and East Yorkshire. If a thunderstorm can develop then it could become well organised and could bring the risk of a tornado.

 

A lot of ifs and buts but one to watch.

Estofex is agreeing with you and has issued a level 1 for the chance of isolated tornado events in a small corridor. Nicely spotted.

According to a couple of people I've spoken to this morning, there was a small thunderstorm overnight. It's clear from the radar that something developed south of here around 2am although it doesn't look that active from precipitation rates... No sferics in the archives but there was quite a bit of thunder apparently.

Typical that it began to develop around 1:45am, just after I last checked the radar, before going to sleep, at 1:30am....
