Sunday was best forgotten as regards weather as it was dark all day with much rain. The light easterly air stream combined with the cloud meant a very cool day when the thermometer struggled to reach a maximum of 17.4C late in the afternoon at 16.46 when the cloud thinned giving a little brightness. This peak was 1.7C below my 40-year average and the coolest day since the 13th, which was even cooler at 13.8C.
The diurnal range of temperatures was minimal at just 3.0C, the difference between day and night extremes. The minimum of 14.4C was logged at 06.25 on Monday, which was a significant 5.7C above my 40-year average, so a very mild night.
The rainfall for the past twenty-four hours amounted to 37.9mm making it the wettest day since 17th September 2023 when 49.7mm was logged. The total rainfall for September at 08.00 was 117.4mm. This total was 186% of my 40-year average or plus 54.4mm.
Monday again struggled to arrive being very dark with very low cloud and continuous rain with little air movement. The humidity read 100% at 08.00, not a common occurrence other than on very foggy days, as the air is saturated after the wet day on Sunday and rain continuing to fall.
The depression has moved very little over the past twenty-four hours with a large area of rain centred over southern England and slowly rotating anticlockwise that will produce steady rain during daylight hours and add substantially to the monthly rainfall total.
