Temp here in Nantymoel (230m) is 3.4ºC, Dew point 2.2ºC. Air temp is dropping very slowly, dew point has been constant for a good few hours now though. Light rain here. Drove over the Bwlch mountain (440m) about 15 mins ago and it's rain up there at the moment, no sleet yet. Car thermometer indicated 2ºC up there but as someone else said, not sure how accurate these are.
