Some great pics attached of thunder clouds recently taken in the Caribbean zone, posted on UKweatherworld - BTW I frequently visit this site, without being enrolled - it's a great place to hang out, a sort of all-in weather site for experts and amateurs to exchange ideas and experiences.

Hi all Im just back from another 11 week trip over the better months of the year for weather out in the Caribbean. It was a good trip all round though somewhat frustrating in terms of photography as we were on a steady run back and forth between Trinidad and Guyana and whilst this kept us relativ...
Incidentally the reason thunder clouds within the tropics always appear more impressive than the ones we get back home is because they really are! The atmosphere bulges around the tropical belt, the base of the troposphere being higher than at our latitude, and this allows the cumulonimbus storm-producing clouds in that region to grow to heights as high as 60,000 above sea level - at which point they come up against the tropospheric inversion, or "cap", spreading out into the characteristic "anvil cloud" shape so well exhibited on these shots - whereas over the UK thunder clouds rarely exceed 40,000 feet in height, even in summer.

A nondescript day according to the forecast, grey with rain later, so the washing will need to go out now to take advantage of the air movement before the wet cancels it out.
Yesterday was a bit short on full sunshine, but a gentle breeze and lack of rain were particularly welcome for the event at work as most of it was outside, and it became quite mild from midday on as well.

The early low cloud with drizzle has broken to some extent here, with temperature up to 19 C, but a fresh to gusting strong breeze, as expected with a tightening pressure gradient. The latter will be face-on as I return from a shopping spree this afternoon, which will not be much fun - but winds from the subtropical source have to be strong enough by this stage in the season to carry such high surface temperatures this far north.
Tonight the ever-inevitable cold front swings right through, to be followed by successive shortwave convergence troughs, each one bringing strong winds and heavy rain tomorrow, especially south of the Midlands, where a broad yellow warning of thunderstorms has been out out for the morning, followed by much cooler brisk west-north-westerlies, but gradually drying conditions lasting up to the weekend, though the outlook continues to look changeable and fast-moving.
