UK long range weather forecast

The start of this period is most likely to be changeable. Showers or longer spells of rain remain prevalent, with heavy bursts still likely in places on Sunday. Drier and brighter interludes are possible as well, mainly across western regions, however these may be short-lived as further bands of rain are expected to arrive from the west. Eastern coasts may be rather grey and misty at times. The latter part of the period looks likely to become more settled, albeit with some wetter interludes, these most likely in the south and west of the country. Stronger winds at times, but temperatures remaining close to average, feeling pleasant in any sunshine. There is potential for overnight frost where skies are clear in the north and east.

Updated:

Throughout this period there is likely to be a split in conditions between the north and south of the UK. Any unsettled weather is likely to take a southerly track, while higher pressure to the north should provide some generally drier weather here. Overall, it is likely to be somewhat drier than March across the country. Temperatures are uncertain, but there is a potential for cooler conditions at times, especially in the north and east, with a chance of overnight frosts.
