Precipitation now breaking out in SW England and still very light snow here

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.

I think had there been just some precipitation around this past week
peoples' perception of this "cold spell" would be far different to
what it is currently ie "what's the big deal" seems to be the majority
consensus in East London

It's raining now, (only a shower - but a sharpish one) and there were
some rain showers a couple of nights ago. (5mm at Culdrose, 1.5mm
here).

No air frost here this Winter, no ground frost here that I've seen. In
fact, looking back through my records, I can't find an easterly/
anticyclonic spell this long without an air frost at some point. The
low temperatures (so far) have been home grown under still conditions
rather than imported. In fact the Baltic is still warmer than normal

hardly a normal blocked situation.
