Still no air frost this winter, and it now looks unlikely during this
spell.

January 2010 saw 14 air frosts and 5 days with a snow cover at 09:00, even
down in Penzance.

Have we forgotten what a cold spell can be like?

No air frost here, either, though the min Friday morning was 0.0°C and
the max's Thursday and Friday were 4.0 and 4.8. This area usually does well
in a NW'ly and today (Friday) has been almost entirely cloudless.
I wouldn't call it a cold spell. For that there would have to be a few
max's below 0°C here and there haven't been any and I see no prospect of
any. There may be some cold nights but I think there'll be too much cloud.
================

I always thought the definition of cold was 3-4 deg C below normal? So for
you Tudor maxes of 3-4C would be cold. Sub zero max. would be very cold. My
max. yesterday was 5C (technically only rather cold) but it was snowing with
snow on the ground, so was that cold? All a bit subjective really.
