Next week is looking pretty good for many areas with high pressure being the dominant feature and whilst it won’t be scorching UK wide some areas may see temperatures creeping into the low-mid twenties. The charts below show 850hpa temperatures and sea level pressure for Monday of next week. As can be clearly seen high pressure is in play and as a result winds will be light with temperatures responding nicely. The yellows and oranges on the 850hpa temperatures and sea level pressure chart represent milder upper air which has an affect on temperatures at the surface.

Some of the weather models are indicating a slow change from the west/northwest with cooler air moving into the UK, however it has very little support from other weather models and any cooler air that moves in would only be temporary. The GFS weather model and the ECMWF model suggests high pressure with warmer temperatures even by midweek of next. The below charts are from the ECMWF model showing next Wednesday and Thursday’s 850hpa temperatures with sea level pressure and they both suggest high pressure with warmer temperatures remain in charge.

The maximum temperature chart from the GFS weather model for Thursday 24th May suggests the high teens-low twenties across many areas. For some areas these temperatures would be higher due to the low resolution of the GFS weather model.

Looking further ahead into the long bank holiday weekend we may just see temperatures creep up even more with a cracking weekend expected at the moment, however the weather models are suggesting it cooling off/going downhill on bank holiday Monday (typical) but in forecasting terms it is some time away. Below are charts from the GFS weather model showing maximum temperatures and 850hpa temperatures for next Friday. Below these charts you will also find a couple of charts showing 850hpa temperatures from our CFSv2 long range forecasting model covering later in the period and as can be seen the start of June is looking good at the moment!

To conclude next week and the bank holiday weekend is looking fairly decent at the moment! I hope you enjoyed this article.
