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.
