Planning Outlook
Low pressure dominates across Britain into midweek, bringing showery conditions widely, some more organised bands of rain at times. Some heavy and thundery downpours forming, mostly into the afternoons, becoming focused further south with time. Fresh westerly winds turning northerly and temperature lowering later this week, dropping close to freezing on high Scottish tops by Friday and frost may occur in Highland glens over a couple of nights. More often dry with rare lighter showers over the weekend as higher pressure builds. Strengthening south-southwesterly winds into early next week with a risk of rain returning from the west, but warmer temperatures are likely.
