Quick Summary

A Met Office warning has been issued for Northern Ireland due to thunderstorms expected to bring up to 30mm of rain in an hour or two, along with strong winds and hail. The UK's heatwave is set to end midweek as a cold front moves southwards across England, but it will likely be short-lived and not deliver significant rainfall to the far south-east, including London and surrounding areas. This marks the 47th consecutive dry day in Wisley, Surrey, with many other parts of the UK experiencing below-average rainfall in June and July. Forecast models suggest August may bring more hot weather and low rainfall, prolonging drought conditions across England and Wales.

Story summary

A heatwave continues across parts of the UK, including England and Northern Ireland, with temperatures expected to reach over 30C in some areas. However, a cold front is forecasted to move southwards from midweek, bringing an end to the hot weather. The heatwave has already seen Pershore in Worcestershire and Cavendish in Suffolk hit three consecutive days of heatwave threshold temperatures on Monday, with more parts of southern and eastern England expected to reach heatwave criteria on Tuesday. An area of low pressure has tracked north of the UK, consistently failing to deliver meaningful rainfall to affected areas. Some regions, including London, Essex, and Kent, may not receive any rain at all. The dry spell continues a trend seen in recent weeks, with July marking the driest and sunniest on record for the UK.

Narrative

Wisley in Surrey remains the driest location in the UK, having recorded 47 consecutive days without measurable rainfall, while many other parts of the UK have had a fraction of their normal rainfall in June and July. Further spikes of heat are likely, however as August wears on and the sun gradually loses some of its intensity, the likelihood of extreme temperatures in the high 30s lessens. But it is not uncommon to have spells of intense heat reaching 30C or higher even into September.
