UK long range weather forecast

Starting off with something of a northwest to southeast split; higher pressure located towards the southeast should bring fine and increasingly warm conditions across at least southern UK, whilst there is a greater chance of periods of cloud, rain and stronger winds affecting the north. There will be fine weather here at times as well too however. There's a small chance that fine and very warm weather could extend right across the country early next week, but it's more likely that cloud/rain in the northwest will sink southeast introducing more changeable and cooler conditions for a time mid-week. It then becomes roughly equal chances that we see a resumption of mainly fine and dry conditions versus a continuation of more changeable weather with a mixture of rain and drier interludes.

Updated: 15:00 (UTC+1) on Tue 22 Apr 2025

Forecast confidence is lower than average for this range, although fairly typical for late Spring. A typical mixture of drier and settled periods, and periods of wetter and more unsettled conditions, is on balance slightly more likely than predominantly unsettled or predominantly settled. Temperatures are likely to be around average overall, with a slightly increased chance of warm or hot spells. Any such spells could be accompanied by locally heavy showers and thunderstorms.
