Planning Outlook

Exceptionally warm and humid most mountain areas until later Friday. The range in temperature in the detailed forecasts for Wednesday and Thursday reflect uncertainty in just how far north the extreme heat will penetrate - with more recent forecasts suggesting the (even) more extreme temperatures. Scattered thunderstorms on Thursday and Friday, whilst over the weekend, progressively less warm as fronts begin to come in off the Atlantic, bringing bands of rain and low cloud, particularly affecting western mountains.
