Planning Outlook
A drop of temperature is expected across Scotland during Wednesday as a band of rain drifts slowly southwards, turning to heavy upland snow. Atlantic weather patterns and west-southwesterly winds follow behind into the start of the Easter period at least, but day-to-day detail is uncertain. Temperature and wind will be variable, periods of gales and 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, though bands of heavy rain will sweep east at times. Some windows of drier and brighter conditions, as well as milder days in England and Wales, occasionally milder Scotland too.
