UK long range weather forecast
Through Thursday and Friday it will most probably be cloudy and fairly windy with an area of rain pushing northeast across the UK. Looking further ahead, a north/ south split across the UK seems most likely. Northern and northwestern areas are expected to see further spells of rain, accompanied by strong winds, with the possibility of these spreading to some other areas at times. Further south however, there should be more in the way of dry weather, though even here, there is still the possibility of some showers, or longer spells of rain. Temperatures are likely to be either around or on the warmer side of average, with the warmest conditions likely in the southeast.
Updated:
Although confidence remains low throughout this period, the preferred scenario favours a more settled regime. There should be plenty of dry, fine weather around, though there is still the risk of occasional bouts of rain and strong winds. Such spells are mostly likely across the north and west, but they could spread to other areas at times. Temperatures generally around average, with any periods of particularly warm weather most likely being short-lived.
