UK long range weather forecast

Cloudy and breezy across Northern Ireland and Scotland with outbreaks of rain through Monday, later spreading briefly to Wales, the South West and Northern England. Further southeast it will likely remain drier and brighter with a cold night. Outbreaks of rain in the north and west will then likely ease as high pressure becomes more widely established again. This will bring plenty of dry and bright weather with sunny spells and daytime temperatures around average, but cold by night with the risk of overnight frosts and the chance of fog patches. There is the potential for rain and strong winds to occur at times towards the northwest of the UK with the possibility of these unsettled conditions briefly spreading southeast.


Confidence remains low during this period, however, mixed and slowly evolving weather patterns, typical of spring, are most likely through the end of April and into May. Fine and dry weather is expected to be more prevalent on the whole, with fair-weather cloud and plenty of sunny spells, although all areas are likely to see some showers or longer spells of rain at times. Temperatures are likely to be close to average for the time of year, with warmer spells possible at times.
