The UK is heading into a warmer spell this weekend, with temperatures potentially reaching 26C in parts of England and Wales on Monday, September 14. However, the warmer conditions are expected to be temporary, with cooler weather returning by the middle of next week. Rain will also remain a feature across several parts of the country, particularly during the weekend.
Will There Be A Heatwave In The UK?
Despite the rise in temperatures, forecasters do not expect a UK heatwave. A heatwave is declared when temperatures remain above a specific regional threshold for at least three consecutive days. The threshold varies across the UK, reaching 28C in London and around 25C in Scotland and Northern Ireland. With temperatures expected to fall again by midweek, the upcoming warm spell is unlikely to meet those criteria.
UK Weather Forecast For The Weekend
Saturday, September 12, is expected to bring a mix of rain and warmer conditions. Rain could become heavy at times across northern England, Wales and the Midlands, with isolated thunderstorms and lightning possible. Southern England is likely to stay warmer and comparatively drier, with sunny spells and humid conditions pushing temperatures into the mid-20s.
On Sunday, rain may affect parts of southern England before clearing later in the day. Much of the country could then see drier conditions. Temperatures could reach 23-25C in Wales, the Midlands and southern England.
Monday To Be The Warmest Day
Monday is currently expected to be the warmest day of the spell, with temperatures of 22-26C across England and Wales. Parts of Scotland and Northern Ireland could see temperatures around 20C. Despite the warmth, the forecast does not currently indicate a prolonged period of extreme heat.
What Is The Long-Range UK Weather Forecast?
The warmer conditions are expected to give way to more unsettled weather later in the week. Weather models indicate that areas of low pressure could continue moving across the UK, bringing further rain and stronger winds. The jet stream is also expected to play a role in maintaining the unsettled pattern.
