Planning Outlook
Milder air across all areas by Tuesday, with drizzly rain and low cloud particularly in the west. A drop of temperature returns to Scotland at least during Wednesday, with a belt of rain expected to move slowly southwards, followed by showers turning to snow again on higher areas, possible hail. Uncertain southward extent of rain and colder air beyond midweek - lower confidence in forecast detail toward Easter - high pressure toward the east and south brings some drier weather, but Atlantic weather systems may continue to move near to the northwest of Britain bringing further spells of strong wind and rain, plus fluctuating temperatures in Scotland, whilst further south likely stays milder.
