There’s potential and good model agreement on a late season arctic blast as we end the work week with a high just west and low just east squeezing a stiff, cold northerly air flow down over the British Isles. The models are suggesting a significant hill snow event over the Scottish mountains and possibly Southern Uplands and Pennines with supressed daytime highs for the time of year and a sub zero wind chill.

GFS and ECMWF show a strong northerly flow driving arctic air down over the UK Friday into Saturday.

Looks like a cold high builds down over Scotland following the potential band of rain, sleet and snow. Cold in place along with clear sky and light wind could set the stage for unusually cold mid April nights over fresh Highland snow cover this weekend.

See this morning’s video.
