Saturday 24th July 2021.

You may have noticed a change in the sky during Friday evening showing a possible thundery breakdown and this should occur in the early hours of Saturday morning with some thunderstorms and longer spells of rain and they could be heavy with some localised flooding. There could be a fair amount of lightning.  Rain may be over 25mm in places. The reason is an area of low pressure is going to move close to or over the region this Weekend.

Saturday will be unsettled with some showers and thunderstorms after any early rain and thunder moves away with a short break before others develop. In any sunny intervals the temperature will reach 22C or 23C,down on recent levels. Overnight mild , humid with some further showers, possibly thundery and they will be around on Sunday too. Watch out again for some heavy ones. Max on Sunday 21C to 22C and down to 13C at night.

On This Day- July 6th 1973

A remarkable deluge on the when 118mm (4.65 inches) fell in just 2½ hours in the Hook-Chessington area of Surrey. Some 51mm fell in 45 minutes. 300 homes were badly flooded in what was one of Britain’s heaviest rainstorms. Fire engines were called from all over Surrey –and Kent as well as Greater London. Yet only a few miles down the road it was dry. A slack low pressure system straddling the country.

In 1991 thunderstorms gave Scilly 103mm of rain but Shetland reached 23C and Tiree in the Hebrides 26.3C.
