Windrush Weather

High pressure in charge this coming week

Sunday 1st November
The fog, then mist, was slow to clear on Saturday that in the afternoon allowed some brightness to come through, however, the high of 13.6C logged at 14.29, was 1.3C below the average for late October. The temperature dropped away significantly during the evening with a low of 2.7C at 22.46, much lower than forecast, which was 4.8C below average. The low temperature encouraged fog to form very early, observed at 22.45, before more thick cloud drifted in that saw the temperature edge upwards to around 6.5C for the rest of the night.

Sunday arrived under foggy conditions again that initially limited visibility to 200m. There is just a whisper of a breeze from the northeast. The mist and murk is due to a very weak, cold weather front that has snuck in from the north and will probably mean very little sunshine today. In fact as I finish this report I notice that the visibility has reduced as the fog has intensified, now limiting visibility to a round 100m. The barometric pressure has edged upwards as the new intense high edges closer.

The new high pressure will become almost resident over Scotland then the North Sea as the coming week progresses. This will feed an air stream around its northern and eastern boundary to come from a northeasterly quadrant all week. The barometric pressure at the centre of the anticyclone is forecast to be very high, around 1044mb, that will keep any further weather fronts at bay with little or no rainfall all week. By the end of the week maximum temperatures are forecast to drop just below the November average.

The total rainfall for October amounted to 129.9mm, which was 143% of my 43-year record, or plus 39.1mm, using the Met Office standard 5″ copper rain gage. It has been the wettest October since 2021 but still much lower than the record amount in 2020 when 191mm were recorded.
