Windrush Weather

Low pressure now becoming dominant

Sunday 9th November
Saturday was a glorious day with much warm sunshine and periods of calm or an occasional light breeze. The mild conditions continued with the thermometer reaching a high of 14.4C at 13.21 being 4.1C above average. Every day this month has brought an above average high temperature. Under a clear sky the temperature began to fall steadily as the evening approached reaching a minimum 2.8C at 01.30 before the temperature began to recover and slowly rise with a temperature of 8.0C at 08.00. This minimum made it the coldest night for a month.

Sunday arrived with just thin cloud cover that gave a bright start to the new day. However, the cloud will build during the morning as a weather front crosses the country after mid-day with rain likely arriving mid-afternoon and becoming heavy during the evening. After dawn fog could be seen to the northeast, over the tops of the trees on the high ground, and for a brief time radiation fog formed in the River Og valley.

The barometric pressure at 08.00 read 1015.6mb, the highest pressure all month, but already showing signs of falling. The situation will change as low pressure systems will be the dominating weather this coming week with sunshine and showers, with the latter predominant. The unsettled weather will come in from the Atlantic on a southerly changing to a westerly breeze by mid-week that will maintain the moist, warm air. However, a change is likely to arrive by the weekend to less warm conditions and a possible change in wind direction to come from a cool northeast.
