Noticed a few stations with -8C dew points, e.g.

Glasgow EGPF 081350Z 34009KT 9999 SCT045 04/M08 Q1025=

which equates to 41% relative humidity.

Should keep the dreaded fog away for a few days.

Hi, Jon,

I was just about to post, you took the words right out of my mouse!

Copley 1430Z T 01/ DPt M10 which gives 46% relative humidity. Lowest
dew point for some time. The light snow cover is frozen hard in spite of
full sun as wet bulb is -2C
