Planning Outlook

All mountain areas of Britain from Tuesday 3rd March 2015

Continued cold and windy conditions during midweek: frequent upland gales and showers of snow and hail, falling to lower slopes Tuesday & Wednesday. Whiteout; risk lightning. Showers begin to ease through Wednesday. From Thursday on, less cold overall, with cycles of freeze and thaw. Whilst high pressure tries to build across southern Britain, most of the mountain regions may remain in a strong west to south-westerly flow, with frequent precipitation and periods of upland gales into the weekend and perhaps beyond.
