Sunday was the warmest day in five days, however, it was still 0.9C below my 40-year average. It was dry day thanks to the almost wall to wall sunshine but the light north-westerly breeze , maximum movement of just 10mph, that set in before midday depressed the temperature. Clear skies overnight saw the thermometer drop below freezing (-0.1C) at 21.05 Sunday evening and reach a minimum of -1.7C at 01.59 early Monday morning. Thereafter the temperate gradually rose.
Monday after dawn revealed a hard frost but also that fog had formed limiting visibility to 200m. By 08.00 some brightness was evident that resulted in the thermometer reading 1.8C having risen above freezing at 07.05.
There are five depressions currently surrounding the UK with the next one bringing cloud later on Monday on a southeasterly breeze, light in the morning, with possible rainfall late afternoon. A low is forming between Ireland and the southwest approaches that will also bring stronger winds late afternoon.
