Met Office June Heatwave Verdict: 25 to 27C weekend forecast
Temperatures in parts of the UK are set to rise by the weekend, according to the met office june heatwave verdict. After a cool and wet start to June, the forecast points to a turn toward drier, sunnier weather, with the warmest conditions likely in England and Wales.
High pressure is expected to build from the south over the weekend. If it spreads across the UK, southerly breezes could lift temperatures to 25 to 27C in parts of England and Wales, with Scotland and Northern Ireland rising into the low-twenties.
Wednesday rain and showers
The run-up to that warmer spell stays unsettled. Heavy showers are expected across the UK on Wednesday, and some of them have a high chance of being thundery in eastern Scotland and eastern England.
Temperatures on Wednesday are expected to be 3 to 6C below average. Lower temperatures are then expected to continue into Thursday as a large area of rain moves in from the west across many parts of the UK.
Weekend pressure pattern
Friday is expected to be drier, brighter and slightly warmer before the weekend build-up begins. The forecast then depends on where the high pressure settles, because that will determine whether the country gets the warmer southerly flow or a cooler north or north-westerly wind.
If high pressure moves right across the UK, the warmer pattern could bring 25 to 27C in parts of England and Wales. If it stays to the west or south-west, temperatures would be held to the low-twenties in the south and the teens further north.
Heatwave threshold
Even with the rise in temperatures, it is too early to say whether conditions will stay warm enough for long enough for an official heatwave to be declared. Some computer models point a little warmer than the current forecast, but others keep the country on the cooler side.
For readers planning the weekend, the practical point is simple: the warmest spell is possible, but the final outcome still hangs on how far the high pressure reaches before the end of the week.
