Changeable weather to come after hot spell

7 Sep 2021 01:45 PM

Much of the UK is currently in the midst of warm conditions for the time of year, with temperatures in excess of 30°C expected in some southern areas.

Only six Septembers in the last 50 years have experienced temperatures above 30°C, with three of those occurring in the last decade (2020, 2016, 2013). That warmth is no longer confined to the south as it was earlier in the week, with Scotland having a chance of hitting 28°C on Wednesday.  

However, the conditions are expected to change for most over the next few days, as the southwest of the UK sees the first of a front moving in from the west.

A yellow thunderstorm warning has been issued for a large part of the southwest on Wednesday, lasting from 11:00 to 21:00. Although many areas will avoid the worst of the showers, thundery downpours are possible in the area and between 30mm and 50mm of rain could fall in less than three hours, although only a few spots are likely to see those totals. Elsewhere in the UK, and especially in the north and east, Wednesday will remain a fine, dry day with heatwave thresholds likely to be reached in some eastern parts of England.
