Windrush Weather

Colder still by night. Freezing fog.

The migration to a more appropriate platform should see the website quicker to respond since the change Tuesday with the hoped for updates on the graphs and associated data being installed by my IT technician soon, beyond my scope.

The many hours of glorious sunshine on Tuesday lifted the maximum temperature above the 39-year average (+1.4C) with a peak of 9.4C at 14.48. As on previous nights, under clear skies, the temperature began to fall late afternoon to reach a minimum of -5.8C in the early hours of Wednesday at 03.42. The low of -5.8C was a significant 7.4C below the average and was the coldest night since 25th January (-7.7C).

It was the twelfth consecutive dry day and a UV value of 1.4, classed as ‘Low’ not surprising in early February but the highest since 30th October, so the sun is gaining in strength!

After 00.35 the thermometer began to edge upwards to reach -4.3C at 08.00 on Wednesday due to fog forming that at dawn limited the downward temperature trend and visibility to 150m at that time.

The dry, sunny days with minimal air movement are due to the influence of the intense high pressure system, still reaching from mid-Atlantic to Russia, but the signs are that it is beginning to retreat with a small drop in pressure, a reading of 1-37.1mb at 08.00, down 10mb since its peak on Sunday.

The air movement over the last two days, not strong enough to call a breeze or a wind, with peak movement of 9mph and 7mph respectively, have been from the south or southeast.

The soil temperature at a depth of 5cm has dropped to 0.2C at 0800, the lowest since 26th January.
