... similar sequence here in east Berkshire. At 0115Z, a *very* light
dusting of crunchy snow (actually most of it would have been encoded as
'sleet' really .. between just after midnight to 01Z). Then fine/dry,
then some *rain* with the temperature rising to around 2.7degC at around
04Z, then it's all gone! Not a trace of the stuff left. A tongue of warm
air entrained in the NNW'ly flow lifted the temperatures sufficiently to
allow PPN to reach surface as rain, rather than snow on the main frontal
band - the first lot of sleet/snow was a discrete tongue of
precipitation just ahead of the main band.

Snow started here in Chalfont St Giles about 2330. I don't know when it
stopped but there's a complete cover this morning of about 2 cm.
Untreated roads have a complete cover. Present temperature -1.0c
