The GFS seems to have this cold low sticking around for the next few
days with the 522dm line near or south of the south coast so there is
still potential for a decent snowfall anywhere. Having said that the
Met Office seem to be forecasting surface temperatures of 6C by day
which would rule out any snowfall settling - surprised that temps would
be that high with such a low thickness.

At this time of year the sun is getting some real power, so an hour or
two of sun will cause the temperature to pop up. But it's only the air
near the surface that gets substantially warmed, so that if the sun goes
in the temperature can fall quite quickly.
