All mountain areas of Britain from Wednesday 4th March 2015
Remaining cold on Wednesday with further snow and hail showers, although conditions easing. By Thursday, rain and snow on higher areas, particularly western Scotland. A rise in freezing level will result in a steady thaw of lying snow, most substantial lower slopes. Toward the weekend, high pressure building across southern Britain brings widespread milder air. However upland gales are expected across Scotland, and substantial precipitation (mostly rain) particularly the West Highlands; resulting in significant snow melt.
