Precipitation now breaking out in SW England and still very light snow here
in Haytor. More wintry precipitation in Scotland in places and some light
snow expected in eastern England spreading southwesterwards tonight. Could
be a few surprises later as it possibly turns moderate due to
de-stabilisation as colder air aloft comes across.

Anyway main emphasis for England and Wales looks like being high pressure
this week with yet more quiet frosty weather. With time a strong inversion
is likely to develop as very cold surface air advects north from France and
mild air at 850hPa (which is a long way up due to high pressure) sinks
south. Fog/low cloud is possible due to low-level moist feed in the north
but in the south the drier air from France may ensure fine sunny conditions.
Scotland and Northern Ireland, however, will see increasingly milder and
drizzly, cloudy conditions but the high may yet hang on further north if
anything.
