Moderate snow, heavy at times, has covered everything here in Hemel Hempstead (149m) during the past 90minutes. About 2 or 3 cm on the grass and the wind has picked up, blowing the now much finer snowflakes horizontally at times. Everything below the snow is very wet following 13mm of rainfall over the past 24hours, so it shows how intense the snow has been in order to establish a cover. Current temperature is 0 C so it could be very awkward for travel in the morning if it all freezes and more snow accumulates. Gritter has just gone by! Out of interest it was snowing heavily on top of the Chilterns near Ashridge, by 3.30pm and was starting to settle Potentially there could be quite a cover by now.
