The warm, moist Atlantic air persisted for much of the daylight hours on Tuesday with the thermometer rising to a peak of 12.8C at 13.26 some 4.7C above my 40-year average. The temperature then slowly drifted downwards to around 10C until late evening when the cold front arrived. By 22.30 the temperature had dropped to 8C and at 23.00 6C. The minimum of 3.8C was logged at 02.01 early Wednesday before lifting title and dropping back to 3.8C just before sunrise.
The wind direction, having been mainly from the southwest all day, suddenly veered into the north and northeast just after 23.00 as the cold front passed our way.
Intermittent rain was observed at 14.40 and then from 17.35. However, the main rain band arrived just before 21.00 and continued for several hours amounting to 19.5mm making it the wettest day since 4th January (29.3mm).
Wednesday dawned cloudy and cool under the influence of the light northeasterly air stream. We are now under the influence of two low pressure systems to the west of the UK. As a result the barometric pressure has dropped further with a reading of 1006.1mb at 08.00, the lowest pressure since 17th January.
The recent warm days have now been replaced by a much cooler air stream.
