10/12 air frost days
Posted: Fri Jan 06, 2017 5:31 pm
Out of the last 12 days (December 26th-January 6th), I have recorded 10 air frosts. Only Dec 31st and Jan 1st failed to record a temperature below zero.
There were no extremely low temperatures in that period (the lowest in those 12 days was -3.4C on Jan 3rd) nor were the maximum temperatures unusually low. It was more a case of clear skies leading to radiation cooling. The lowest temperature of the winter half year still stands at -5.4C on Nov 30th.
The same period was also very dry with the only rainfall being 6.3mm on Jan 1st.
Looks like a change on the way, though, as there is some rainfall now and cloud means there is unlikely to be a frost tonight.
What has been missing so far this winter is snow - I keep looking at the forecast charts and hoping that we may get at least some of the white stuff!
