The driest and coldest air has already passed you in Norfolk. At 1900Z my
dewpoint sensor showed -9C with the air temperature just above freezing. I
didn't believe this and looked on XC weather to confirm. An area from about
Oxford south west to Bournemouth and south-east to Brighton was reporting
similar conditions.

Something seems to be generating these pulses of unusually low dewpoint air
over Central Southern England as this is not the first time this winter I
have seen similar pools on the XC weather charts. As Dave says, these
conditions are really unusual compared with recent late Winters / Springs
and the onset of spring flowers / opening of buds is being seriously delayed
compared with what we have been accustomed to.
