UK long range weather forecast

After any fog or mist clears from the south of the UK, it should be another mostly dry and sunny day on Wednesday for many, with patchy rain or drizzle here and there. Temperatures staying warm, especially towards the south. Moving into Thursday and Friday, it is likely that we will see the reappearance of some wet weather but temperatures are still likely to remain warm. Looking further ahead in this period, and there should be a good deal of dry and settled weather with spells of sunshine. The driest conditions and warmest temperatures are mostly likely towards the south, and whilst still warm in the north, there may some windier and wetter periods at times and a risk of overnight frosts.


Although confidence is low during this time period, the most probable scenario is that dry weather should dominate, with some interludes of more changeable weather at times. Towards the end of the period, there appears to be some signals that it may be drier towards the northwest UK, with some wetter and windier weather further south. Temperatures are likely to vary around the average or even slightly above, with some large variations between day and night.
