UK long range weather forecast

The start of this period is likely to be unsettled and showery, especially in the south where a spell of persistent rain and strong winds is possible, though temperatures should return to near-average. Through the week, there is some uncertainty, but high pressure may build to the east, bringing drier and more settled conditions (with some spring sunshine) for a time, especially in eastern areas, with western parts always more at risk of seeing further spells of rain and strong winds. Towards the middle of March, a typical mixture of conditions looks most likely with spells of rain interspersed with brighter, drier intervals. Temperatures are likely to be around, or a little above average, but some cold nights are certainly still possible.

Updated:

During the rest of the month, there no especially strong signals on top of climatology at this range, though there is perhaps a slightly increased chance of spells of high pressure developing, probably centred to the north or west of the UK. Days of occasional warmth are more likely towards the end of the month as the sun continues to strengthen, and rainfall amounts would typically decrease a little in this period anyway, even though some wet and windy days are still likely. Winter hazards such as snow, and overnight frost and ice could occur anywhere, as often happens in March, but are most likely towards the north of the country.
