Overview of hot weather over the next 5 days
Although still warm or very warm for parts of southern and western England at the start of the week, the more widespread hot conditions from last week have eased over the past weekend. Temperatures are likely to peak around 26-27C in localised spots, mainly in the east of Southwest region, west of Southeast region and south of West Midlands regions on Monday and perhaps Tuesday, before gradually reducing through the working week. Overnight temperatures at the start of the week are likely to be mostly in the range 13-16C, also just below the Low impact threshold. Settled conditions are likely to dominate for the most part, although there is the chance of a few showers across some southwesterrn areas through Monday and Tuesday, with a low chance of thunder. The chance of significantly breaching the Low impact Heat Health temperature alert threshold is now considered unlikely, and the previous Alert should be considered for cancellation.
Overview of hot weather over the next 6 to 15 days
There is an increasing chance that more changeable conditions from the Atlantic will extend east across the country in this period, bringing spells of rain and showers at times. Temperatures likely to be closer to average than recently, although still above avergae at times.
Overview of hot weather over the next 16 to 30 days
The weather may become more changeable during this period, with spells of rain and showers followed by transient settled periods. Temperatures are likely to be closer to average on the whole, although occasionally above average. However, the chance of further hot spells is reduced compared to the first half of August.
