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.

I'm starting to fantasise about a repeat of the Christmas snowstorm of
1927, where in SE England rain turned to snow around dusk on Christmas
Day which continued overnight and into Boxing Day, with the snow being
whipped into deep drifts by gale-force north-easterly winds. OK, very
unlikely to be repeated, but not beyond the bounds of possibility, the
way the models look this morning.
Blimey John . sounds like you were there when it happened.
You're the second person to say that.
