Thursday brought us a bright, sunny start to the day but by mid-morning in began to cloud over and just before mid-day an extremely heavy and intense shower arrived that caused some flooding on some Marlborough roads for a brief period. The brighter morning saw the temperature climb to a maximum of 17.3C at 11.29 before falling back a little as the cloud and rain arrived. The wind as forecast, backed into the northwest just after midnight, heralding a cooler airstream that saw the thermometer steadily drop away to reach a minimum of 7.5C at 07.53. The maximum was 1.8C below my 40-year average and the minimum was 1.2C below my 40-year average.
Another 14.8mm of precipitation was recorded taking the monthly total to 201.0mm, which is 319% of my 40-year average for September making it the third wettest month in a year, not just September, since my records began in 1984, using the recognised Meteorological Office 5″ copper rain gauge.
Friday revealed another wet start to a day with steady rain driven on by a strong northeasterly breeze. The strong wind from the northwest is producing a wind chill this morning so that outside it feels more like 5C than 7.5C.
The two depressions will join force as the day progresses and migrate into the North Sea, but the cooler airstream on the strong northeasterly wind will continue throughout the day. The barometric pressure is rising strongly, up 12mb since 08.00 yesterday, that will see the rain depart our area, probably soon after midday and bring a brief, drier period over Saturday.
