Valleys and some sheltered higher areas will see some frosty and misty dawns but by the afternoons many valleys will warm up toward 20C. Briefly cooler air drifts back into northeastern areas later on Saturday, with a risk of some patchy nuisance rain here and there Sunday into Monday. Strong April sunshine widely across the mountains, beware risk of sunburn. Some uncertainty about the location of the centre of high pressure, with a risk of strong, gusty winds across England and Wales next week.
