This week coming (19th March onwards) will see a fairly severe cold northerly outbreak over the UK and western Europe with fairly widespread snow to low levels. Looks like about 40-70cm of snow for many places. Following chart is precipitation accumulation up to 144hrs. 850mb (5000ft/1500m) temps for the next week or so. Looks like pretty widespread temperatures of -10C or lower at 1500m which is not bad for late March.
