Planning Outlook
A drop of temperature is expected again across Scotland during Wednesday as a band of rain then upland snow drifts slowly southwards. Atlantic weather patterns and west-southwesterly winds likely continue into the start of the Easter period at least, a risk of further gales over the mountains. Temperature may remain variable, possibly often cold over the mountains with snow and hail showers at times to lower elevations at least in Scotland, sometimes more widely, mixed with some spells of rain - precipitation generally most frequent west and northwest. Some windows of drier and brighter conditions, but day-to-day detail is uncertain.
