Planning Outlook
A brief colder period with the wind easing on Wednesday and Thursday with bright sun breaking out - some snow showers will affect high terrain in Scotland, some hail mixed in as well. Westerly wind returns as Thursday goes, bringing bands of rain, low cloud and strong upland winds across Britain. Saturday remains blustery and showery but with bright breaks forming, and then Sunday sees a more settled day as a small area of high pressure builds in from the south. The following week looked mixed with bands of rain coming and going, punctuated by regions of high pressure, but typically on the cloudy side. Generally mild temperatures.
