Planning Outlook
Quite warm by Tuesday, but strong to gale force southerly winds widely, very gusty in places, not just over the highest tops; dry for many, rain encroaching into western Scotland, thawing of recent snow. Staying warm on Wednesday for England & Wales at least, becoming cooler over western Scotland, then more widely cooler Thursday; milder by Friday, then likely chilly again by weekend - cooler spells will drop sub-zero on Scottish tops. A changeable mix of weather with some rain and showers with snow or hail on the hills, and often windy late week into the weekend in Scotland, whilst England & Wales will be generally drier and less windy in the outlook.
