Planning Outlook
Staying broadly fine likely through the weekend into early next week at least - dry with pleasantly warm temperatures and often plenty of sunshine. Some coastal fog rolling inland overnight for misty dawns in places this week. Valley temperatures rising to 25C or above, typically warmer in Wales and Peak District. Gusty easterly winds for England and Wales. An ongoing very high risk of fire with extremely dry ground conditions. Into the weekend, northerly breezes develop more widely, a cooling trend for a time, particularly Scotland where summit temperatures likely dip back below 10C; some cloud may be drawn onto northern mountains at times, small chance of isolated showers.
