Tideswell, Derbyshire - Thursday 26th January 2017
----------------------------------------------------------------

0630z 14007kt 0400 -SG FZFG 8St001 -02.1/-02.4 1019
RMK: The first genuinely bitter morning of the winter.
Very slight snow grains.

0900z 15004kt 2000 BR 8St004 -02.1/-02.7 1019
RMK: The fog has lifted into low cloud. Not much of a
breeze yet but what there is is very cutting.
09-09z: Tx 5.7 (1345z) Tn -2.2 (0830z) RR trace
15-09z: Tg -2.2 00-24z: Sun 6.6

1700z 16007kt 1500 BR 5St004 8Sc012 -01.9/-02.4 1016
RMK: Very grey and hazy all day with very slight snow from
time to time but this didn't amount to anything. Apart from
very early this morning we didn't see any of the freezing
fog that was forecast for today. With only a relatively
light breeze it turned out to be an OK day for a walk.
Max temp -1.8°. Despite the all-day freeze, any water on
untreated hard surfaces has mostly remained liquid. Also,
the soil surface has only half-heartedly frozen a bit.
Presumably the cloud cover has prevented surfaces from
radiating to space and conduction from below has balanced
the effects of contact with the sub-zero air.

Just had a look at the data for Manchester for today, overcast with the temp an almost constant 0C. Seems pretty grim.
Chance of rain here tomorrow actually, should relieve the monotony of endless virtually cloudless days with a temp around 30C
