Monday 24th November
There was quite a contrast on Sunday between the very wet Saturday and the drier and brighter day yesterday, that saw the thermometer rise close to the average (-0.2C) with a peak of 10.1C at 13.27. There was a light passing shower at 22.10 then more persistent rain starting at 23.00 that in amounted to a daily total of 3.8mm. There was another shower into the early hours that triggered the automatic rain gauge just before 05.00.
The wind had backed into the northwest overnight, a cooler direction, although the minimum of 3.9C at 03.10 was due to the thick cloud cover, being just 0.1C below average.
Monday revealed the cloud cover from the back edge of the recent weather fronts. There are a couple of minor shower clouds nearby that will maintain the cloud cover but not much precipitation, if any. The closeness of the depression has resulted in the lowest barometric pressure this month with a reading of 989.3mb at 08.00 although there are signs that the pressure has begun to edge upwards as the low-pressure system eases away. At 08.00 the barometric pressure had risen slightly to 989.5mb.
The recent depression, that yesterday was over the west of Scotland, has eased across the country and is currently leaving the east coast heading towards the North Sea. This relocation produced the change in wind direction to come from the northwest today. As the low-pressure eases away a ridge of high pressure will edge in on Tuesday to give us a sunny day although the daytime temperatures will be depressed thanks to the cool northwesterly continuing. Due to the cool air and clear skies the temperature will sink away overnight Tuesday to produce an air frost.
There is a strong possibility of a very deep depression arriving to the northwest of Scotland on Wednesday that will herald a change from the dry and sunny to cloudy conditions, however, the air stream will see temperatures rise significantly, close to or above the average for late November.
