UK long range weather forecast
Initially dry for many places on Tuesday before cloud and rain arrive later. Into the middle of next week, it is set to return to unsettled conditions with generally windy weather coupled with showers and occasional longer spells of rain at times. The heaviest rain is most likely in the west and northwest, which may also see gales, with a low likelihood of them turning severe, at times. In the east and southeast, there may still be brief interludes of drier and sunnier weather. Temperatures will generally be rather cool, potentially cooler in more persistent rainfall, and overnight frost may be seen in prone parts of the north during any brief interludes of calmer weather.
Updated:
Further into October, conditions are likely to remain unsettled for most. The most unsettled conditions being in southern areas. Generally windy with a chance of gales, however the risk of gales reduces later in the period. Feeling cool throughout with a risk of overnight frost. Lighter winds means that morning fog patches may also become more prevalent towards mid-month.
