A light snow shower this afternoon has recorded the 11th consecutive day of
snow here. However, I dont think I can record any with snow lying at 09Z,
with only patchy covering (ie. hard surfaces have generally melted) and
amounts not more than 0.5cm.

Martin - could you remind me what % counts as 'snow lying ' ? If one had 90%
grass covered but 10% drive not - does that count ?

Tomorrow looks as though it will be the 12th. Saturday possible late and
Sunday looks reasonable and may be the last (for a while)

.... same here in Bracknell: the 11th consecutive day with snow, though
only 2 of those produced significant snow cover. For the 'winter-half',
the number of days with snow/sleet recorded so far is: 17, made up as
follows:-
Nov: 01
Dec: 01
Jan: 02
Feb: 10
Mar: 03 (so far)

.... I'll quote from the 'good book' (Observer's Handbook); others may
find it of use ....

" 4.2.4.2 Snow lying: snow lying means, in general, snow covering the
ground either completely or in patches. For the purpose of
climatological returns a day with snow lying is one in which snow covers
one half or more of the ground of an open area representative of the
station at the morning climatological hour of observation (0900 GMT in
the United Kingdom).
The ground of an open area representative of the station should be taken
to include the open, fairly flat ground easily visible from the station
and not differing from it in altitude by more than 30m. In judging
whether half the ground is covered no account should be taken of bare
patches under trees nor of areas occupied by rivers, ponds, etc."

If I interpret your description above, then you would not be recording a
'day with snow lying', as indeed I have not for here.

Martin.

I don't know if the definition has changed, but didn't it use to be 50%
cover of the area representative of the station? So if there's a lot
more grass than drive (as one would expect), then your example would
count as a day with snow lying. At Cranleigh, we had 3 consecutive days
last week which just about qualified at 9am, even though the covering
was very thin in each case and had almost all melted by a couple of
hours later.
