I shall be pin-pointing Sunday in my weekly forecast as a potential

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.
