Windrush Weather

Saturday was second wettest day this month.

The drizzle and light rain, the first spots of rain triggered the automatic rain gauge at 08.45, continued intermittently throughout the daylight hours on Saturday with a total precipitation of 3.3mm that took the monthly total to 25.5mm when the long-term average is 68.0mm, so a relatively dry first half for February. The continuous low cloud meant little rise in temperature all day just 1.7C, with a maximum of 5.8C occurring at 15.04, being 3.5C below average. The temperature fell away very slowly overnight with a slight increase after 01.00 as the cloud began to thin dropping to a minimum of 0.7C at 07.35 easy Sunday, which was 1.2C below average. The dull and gloomy conditions triggered the UV light sensor, briefly, with a reading of 0.6 just after 14.00.

Sunday revealed a brighter start to a new day with the cloud much higher and thinner allowing some brightness after sunrise but no sunshine. The wind has backed a few degrees and is now coming from the east or east-southeast so another mainly cool and cloudy day ahead.

The first half of February has, as we know, been cool. Looking at the statistics I find that only three days have produced a maximum above average, namely the 3rd to the 5th. The fifteen overnight minima produced just four nights that were above the long-term average, the early hours of the 2nd also the 5th and most recently the 13th and 14th, but only just.

The barometric pressure chart for the past twenty-four hours has shown a bit of a roller coaster as it has risen then fallen twice and then ended up today at 08.00 exactly as it was on Saturday at that time with a reading of 1019.0mb. The battle between the anticyclone and depression continued. The very large area of low pressure mid-Atlantic threw the cloud and rain over the UK yesterday and is not making much movement against the high pressure that dominated all last week.
