The UK faces a fresh 26C mini-heatwave with a string of counties in England set to feel the burn. According to WX Charts, which uses Met Desk data, the next mini-heatwave could send temperatures skyrocketing across England next week.

Highs of 26C will hit Norfolk, Greater Manchester, Lancashire, Greater London, Surrey, Hampshire, Cambridgeshire, Essex, Suffolk, Bedfordshire and Northants on Monday, May 19.

The warm blast will begin on the evening of Sunday, May 18. Netweather TV explained: “This week will probably start off dry and settled especially in the south, with sunshine especially for southern and eastern parts of Britain, but cloudier conditions and westerly and north-westerly winds often affecting the north of Britain.

“As the week progresses, the general tendency is likely to be for the weather to turn more unsettled, with low pressure systems coming further south and bringing bands of rain in from the west interspersed with brighter, showery weather, when some of the showers have potentially to be thundery.

“Temperatures overall are likely to be near to slightly above normal, but substantially above-average temperatures are possible for a time early to midweek, as we may see some warm southerlies or south-westerlies before the Atlantic lows start to move in.

“Overall, temperatures are most likely to be about 1C above normal for most, possibly nearer 2C above in places, most likely East Anglia and the south-east. There is uncertainty around the rainfall totals as confidence is relatively low on the extent to which low pressure will dominate late in the week, but overall rainfall is likely to be near or a little below normal for most of us.

“Sunshine will most likely be above normal in most parts of eastern Scotland and the majority of England, but may be near or rather below normal in some western areas.”

The BBC Weather and Met Office forecast from May 9 to May 18 explains: “Dry across the UK at the start of this period with clear or sunny spells for the majority of places. Cloud will likely thicken across the far north and northwest during the weekend with some outbreaks of rain for a time. There is also a small risk of some heavy showers in the far south or southwest.

“Through the following week, high pressure will be dominant across the UK. This will bring predominantly fine and dry weather for the majority of places. A few light showers are possible at times, but heavy rainfall is not expected.

“Temperatures are likely to be slightly above normal for the time of year, although there is a chance of some cold nights.”
