Colder air is blowing in on a brisk westerly wind which is touching gale or severe gale-force across North/Northwest Scotland. But reinforcing cold air with origins stemming back to the Davis Straits arrives this evening.
This morning’s infrared satellite view shows that the cold air has made it to Scotland but coldest air remains well out over the Atlantic with convective snow showers popping over the relatively warm ocean below. This air shall be over us by tomorrow…
Remember in yesterday’s video how I showed you the bitterly cold air blowing off the Davis Straits and how this would be over us Tuesday. That air arrives in ocean modified fashion tonight.
With frequent, intense convective showers pushing in tonight, the column shall cool, likely supporting snowfall even to lowland Scotland tonight. Some could waken to a covering Tuesday AM.
850mb temps considerably cooler tomorrow at 11.00 compared to this morning at 11.00.
YELLOW WARNING for snow and ice issued by the MO.
