A hot spell looks increasingly likely in the UK next weekend & early the following week Here’s the box and whiskers from ECMWF for London High 20s / low 30s Celsius most likely But there’s a lot of spread (large boxes = uncertainty), from low 20s to mid 30s June record temp is 35.6C, set in 1976

The UK’s winter weather still at a crossroads end of the upcoming week. The cold-ish southeasterly either turns into a very mild southwesterly or a very cold easterly. Factors such as the MJO (increase in Pacific tropical rain) and polar vortex likely to influence but to an uncertain extent

January 2025: Whilst the UK's mean temperature was 0.9C below average, Europe was 2.51C warmer than the 1991-2020 average. This partly explains why the upcoming easterly winds aren't as cold as you might expect in February

Storm Bert will bring multiple hazards to the UK this weekend but also significant contrasts from place to place and from hour to hour. Here's a thread of graphics that highlight some of those contrasts. First, a snapshot at 7am on Saturday - wet, windy and mild for some, heavy snow for others:

It turns significantly colder in the north during the next few days but the arrival rain-bearing Atlantic systems delay the arrival of cold air in the south until late Tuesday. As the rain mixes with cold air, the greatest risk of snow is over northern hills - see Met Office warnings.
