Planning Outlook

High pressure weakens into midweek. Some passing rain/showery bursts into Wales and England on Wednesday will lead to a mostly dry Thursday and Friday. A northerly breeze will lower temperatures; freezing levels will lower to high terrain of north and east Scotland for a time. In the short-term, ground conditions remain extensively dry, water courses are very low and the fire risk is very high. Weather turns very unsettled into the weekend as a strong frontal system arrives from the west on Friday night, bringing heavy rain and strong winds to all areas. Showers and a brisk wind will follow into the weekend.
