Planning Outlook
Exceptionally warm and humid most mountain areas until later Friday; valley temperatures approaching the low-to-middle 30s in England and Wales, with hill temperatures approaching the high 20s at least. Scotland will be slightly cooler, though temperatures will still reach the low 20s on many slopes. Scattered thunderstorms on Thursday and Friday, with a risk of extended torrential thunderstorms on Friday afternoon in northern areas. Over the weekend, progressively less warm as fronts begin to come in off the Atlantic, bringing a strengthening wind and bands of rain and low cloud, particularly affecting western mountains. Into the following week, Atlantic westerlies will dominate, with an indication of high pressure to the south producing dry and bright windows.
