Default West Cornwall - Reverse snow line - sort of

Well, sort of.

Just as the N wind set in the sleet turned to heavy snow. To warm toreally settle, but visibility 800m at times.

Anyway, Morrison's was put on hold as I headed up to the moors. Immediately behind Penzance at 150' or so the fields were sort of white. Then as I headed higher, the snow turned to sleet. By the time I reached 500' it was rain. It was a case of being nearer the north onshore coast more than offsetting the affect of altitude. I've known that happen a few times in a northerly, rain on the highest points (800'ish) which are just a mile from the north coast, but a snow cover just behind Penzance at 200' or so. Looking east along the peninsula, you could pick out the line where the rain/sleet off the sea turned to proper snow, 2 or 3 miles inland.

The only area in west Cornwall where it's properly settled for more than a few minutes, is the Redruth to Helston cold zone. Well away from the north coast and fairly high. E.g. just to the south of Carn Brea.

GFS are now forecasting rain showers here by day, and frequent quite heavy snow showers this evening & night. It would be good if that's right.

Anyway, all interesting stuff

Graham
Penzance 1st air frost last night, -0.7C, despite it being cloudy.
