The snowfall decreased during the morning, turning to sleet. More sleet, but predominantly rain fell in the early hours of Monday morning producing 9.2mm of precipitation, which brings the total for December to 31.4mm. The snow was wet in nature, sticking to any surface on which it fell. To obtain the rainfall figure I carefully scooped out the snow from the rain gauge and slowly melted it to add to the rain that had fallen earlier.
Although the maximum recorded was 3.2C, this resulted from a short pulse of slightly warmer air around 10.20 on Sunday that lasted for just over half an hour when by 11.00 the thermometer dropped back to 0.8C and stayed there for most of the day.
The overnight thick cloud was intensified, as was the precipitation, from the effects of another deep low pressure system, this time centred over the continent.
The temperature at 08.00 was 1.1C with strong northeasterly winds gusting to 32mph at 06.53 and moderate rain and some sleet.
A notable feature, meteorologically, was the extreme fall in barometric pressure as the intense low-pressure system crossed this area dropping 33mb in 24 hours, from 1019mb on Saturday to 981mb on Sunday morning. Technically called Cyclogenisis when the barometric pressure fall is in excess of 24mb in 24 hours.
