RMK: A claggy morning with a very slow thaw in progress.
There's still lots of deep snow on the ground but the cover is
now less than 50%. It's an anomaly in the system whereby today
won't count as a 'snow lying' day, even though there are
still roads blocked by deep drifts, but a day with a uniform
slight dusting would count. The rules appear to assume that
snowfall always produces an even cover and do not address the
situation in which dry powdery snow falls with a strong wind
blowing.

Quite agree Norman, there were several days last month when the
ground was clear at 0830Z but by 0900Z we had a full cover of 1cm.
snow, only for it to be all gone by 1100Z still constituting a 'snow
lying' day. Doesn't count today when we still have 45cm. lying snow
but the road out of the village has been cleared and we can finally
escape!

Even down here on the tip of Cornwall, there are still drifts along the hedgerows, 3' deep in places, from the blizzard of 28th of February.

This despite no snow since 1st March & the last 4 days seeing plenty of rain and temperatures generally in the 5-10C range (over 11C at one point)

Because it drifted a lot, and it rain overnight 1st/2nd, only 1 day with snow lying.
