Weather watchers expecting a day of sunshine have been left a bit damp after torrential downpours his Somerset this afternoon... with a severe weather warning in place as heavy rain, hail, thunder and lightning are expected tomorrow and Saturday.

The Met Office yellow warning of rain is in place from 7pm on Friday until noon on Saturday

The experts say: "Isolated heavy, and possibly severe, thunderstorms are expected to develop on Friday evening across parts of England and Wales.

"These are likely to become more frequent later and spread northwards towards southern Scotland. Some torrential downpours are possible leading to localised surface water flooding, with large hail and frequent lightning also possible hazards.

"The public should be aware that there is a chance of some very localised significant disruption

The chief forecaster says that the change in the weather is due to  hot and increasingly humid airmass expected to spread into the south from the continent.

With large amounts of energy again available in this atmosphere storms could be severe, with torrential downpours and large hail. 30 mm of rain is possible in less than an hour, with as much as 50 mm possible in 3 hours very locally.

Large uncertainty remains regarding areas most at risk from storms, and many areas will miss these altogether, staying largely dry. However, where they do develop, disruption is possible.
