First air frost for a fortnight

Although we did not have any strong sunshine yesterday it was mild with the thermometer rising to a maximum of 9.8C, which is 2C above the mean for December. With clearing skies the temperature dropped from early afternoon to a minimum of -1.0C at 07.37. We have now had seven consecutive days without any measurable UV light.
This morning is dawning with patchy cloud and still wind conditions. A little fog formed in the River Og valley in the early hours as the temperature dropped.
