I shall be pin-pointing Sunday in my weekly forecast as a potential day
for disruptive snow. Not just on hills but eventually for low-lying
populated areas too.

A major trough disruption is about to take place, all models are keen on
it. Initially the air will be too warm for lowland snow and there will
be quite a bit of rain. But as the disruption gets underway, winds will
fall light as the trough stretches and precip. will persist. The warmer
air will occlude out and in the light winds latent heat processes with
melting snowflakes will hasten a cooling process and the wet-bulb
freezing level will come down rapidly. This process most likely Sunday
afternoon and evening. Sunset also obviously aiding the temperature
fall. So a period of moderate or heavy snow in bands then slowly
petering out. One to watch and one where tangerine warnings will be
issued in due course by UKMO. Who gets what and when will have to wait
of course.

Do you think there will be much chance of any lying snow in the Surrey
hills?
