Warmth & Humidity Increases Along With Thunderstorm Threat Across The UK (Includes Video with new format!)

Over the next few days we’ll see temps and humidity continue rising over the UK and Ireland as a ridge lifts north from an increasingly HOT Spain and Portugal where highs away from the coast should easily top 100, some central and southern interior locales may near 110F.

I’ve been onto this warming idea since the start of last week and since yesterday stated the potential involvement of low and mid level energy working into this northbound warmth,  ‘Cape values’ will greatly increase (a measure of convective potential). and we could see thunderstorms as early as tomorrow afternoon as heat surges north and low pressure slides NE into the UK along the boundary between the north Atlantic trough and advancing ridge.

Rain spreads across the southwest of England tonight working northeastwards tomorrow but we should see clearing over the South late morning into the afternoon and this should allow temps to warm to a pleasant summer level of 25C in London. While it remains cloudier across more northern areas, the air mass will become distinctly more humid and this will help produce some mid and late PM thunderstorms over northern England, Scotland and Northern Ireland.

Wednesday and particularly Thursday could see widespread big thunderstorms as the air really heats and the energy becomes a greater influence. I am concerned about the prospects of powerful thunderstorms developing across a large area and these could bring torrential flooding rains, even renewed flash flooding as well as strong, perhaps damaging winds and hail.
