The brief ridge of high pressure produced a very warm day on Monday with many hours of sunshine that boosted the temperature to reach a maximum of 20.5C late in the afternoon at 16.26, however, this was 0.5C below the early June long-term average. The overnight cloud cover minimised the loss of warmth into the atmosphere, however, the low of 10.1C was also below average, just, at -0.1C.
Tuesday revealed a very cloudy start to the new day with the first spots of rain from the weather front observed at 06.25 that amounted to 1.0mm by 08.00. The weather front is fragmented so various rainfall amounts will fall during the morning. A narrow band of more heavy rain is just approaching the Devon coast and South Wales that at the moment looks to bring us a short but more substantial rainfall amount later in the morning, but time will tell.
The very low pressure system to the north of Scotland has a centre pressure of 966mb that contrasts with the centre of the high pressure in the Eastern Atlantic with a centre pressure of 1034mb, hence the gusty winds today as a result of the considerable pressure differential.
Review Spring 2025
The mean temperature for the three meteorological months of Spring, that is March to May, was 1.2C above my long-term average, mainly due to the very warm days, being the highest I have recorded.
The total rainfall for the three month period was just 40.9mm. This was only 23% of my 41-year record or -138mm. This low figure contrasts with the very wet Spring of 2024 when 285mm fell. The trend for Spring rainfall shows a gentle upward trend over the 41 years, from around 176mm in the last 1980,s to the recent average of 180mm.
