[ I'll be doing a full analysis sometime late February and posting it

Today's issue has the following minimum & maximum values for Heathrow
for the 9th to 12th February inclusive:-

MIN(18-06Z): -4, -5, -5, -6

MAX(06-18Z): 0, 0, -1, -1

For Hurn, same period

MIN: -6, -6, -7, -6

MAX: 0, 0, -1, 0.

For such low daytime maxima, the model must think there is a bit of
snow on the ground!

The thickness being below 510 over most of Britain on the 12th might help
also help a bit. ;-)
