We enjoyed 6.5 hours of sunshine that made it the sunniest day since 17th November and the UV level rose to 1.1, the highest since 16th November.
The thermometer fell during late afternoon but began to rise several degrees again, from a low of 5.8C at 1915, as the next weather front and rain arrived.
Rainfall amount was 2.2mm bringing the total for January to 77.7mm. With just one day left this month the total for January is 14mm below the 34-year average.
There was a significant drop of over 24mb in barometric pressure as the current weather front approached, dropping from 1030.2mb yesterday to 1005.8 today at 08.00 today
Monday started with some brightness but the approaching narrow weather front produced drizzle and light rain between 10.45 and 13.30, amounting to 1.1mm.
The replacement of the Tropical Maritime air by a cooler air mass began just after 15.00 yesterday as the wind veered from the southwest into the northwest.
The maximum temperature yesterday of 10.7C, being 4C above the average, occurred at 13.57. From that time until 08.00 this morning, the thermometer fell away continuously for 18 hours, producing a minimum of -3.3C at 08.00 this morning, a fall of 14C. This was the first air frost for 10 days.
This was the coldest night since 13th December under clear skies brought about by the high barometric pressure of 1032.1mb, the highest since 23rd December.
This morning has dawned with minimal cloud and a strengthening sun, triggering the sunshine recorder at 08.40.
Sunday was dominated by the warm, moist air mass originating from mid- Atlantic around the Azores. It gave us a cloudy day, dominated by light drizzle from time to time thus precluding any sunshine.
The precipitation yesterday amounted to 0.3mm bringing the January total to 74.4mm being 18mm below the 34-year January average.
As a consequence of this warm air mass the thermometer rose to a maximum of 10.8C just after midday yesterday but only falling a little to 8.8C at 04.18 this morning. The maximum was 4C above the 34-year January average and the minimum a significant 7.5C above average.
The Tropical Maritime air from the Atlantic on Saturday gave us a wet and warm day with 8 hours of continuous rain producing anther 4.4mm of rain bringing the total for January to 74.1mm, still 18mm short of the 34-year January average. It was the tenth day without sunshine.

There was a drop of 2C overnight before in the early hours it rose again to produce a reading of 9.4C at 08.00. The minimum of 8.4C was a significant 7.3C above the January average.
Sunday morning has dawned with thick cloud, misty conditions and a modest breeze.
The short lived ridge of high pressure on Friday gave us 2 hours of sunshine before cloud again spoilt the afternoon. However, the sign that the sun is slowly gaining strength was the UV level at 0.9, still low, but the highest since 23rd November.
Irrespective of the sunshine, the wind from a cooler westerly direction meant that the temperature only reached a peak of 6.8C, the lowest for a week but average for January. It was a dry day.
Overnight the light cloud cover meant that the thermometer dropped to 1.3C at 02.47 this morning, giving a short-lived ground frost, before rising to 4.3C at 08.00 as cloud built up from the next advancing weather front with moisture in the air at that time.
