Windrush Weather

Author: Eric Gilbert

  • Cold with wind chill

    The last day of November was cold due to the brisk north to northeast wind gusting to 21 mph at its peak. The thermometer only reached 4.6C at its highest being a significant 5.5C below average.

    The high pressures is holding on giving predominately dry weather.

    Sunday arrived with a cloudy, if higher cloud base but again cold. The thermometer fell away to 1.3C at 02.05 early Sunday morning that combined with wind chill meant it felt more like -1.6C.

  • Barometer rises again giving sunny day on Friday

    Friday brought us 5.4 hours of sunken under the influence of high pressure, the highest all month as the depression eased away to the east. Ot was also a dry day, only the sixth this month.

    Regardless of the sunshine the wind was brisk from the northeast that depressed temperatures with a maximum of only 6.9C being 3.2C below average.The clearer skies overnight initially meant an air frost set in with a minimum of 1.0C just after midnight but cloud encroaching from the east meant this gradually lifted so that at 08.00 on Saturday morning the ground frost was still evident but the air temperature had risen to 1.1C.

    However, at first light on Saturday low cloud and mist was evident with a brisk wind veering into the east producing wind chill so that it felt more like -1C.

  • Colder air arrives as barometric pressure rises to highest all month

    For the majority of Thursday the wind came from the west but at 18.25 rain began to fall from the weather front that had slowly been drifting southwards and at the same time the wind abruptly veered into the northeast.

    The daily rainfall total was 7.8mm bringing the monthly total to 116mm being 24.4mm above he 35-year average.

    There were 3.5 hours of welcome sunshine on Thursday that lifted the temperature to a maximum of 10.3C, which was 0.2C above average.

    With the sky clearing overnight the thermometer took a tumble to reach a low of 1.4C at 08.00 on Friday morning that saw the sun shine as soon as it had risen above the horizon.

    A ridge of high pressure promises a drier and brighter day on Friday with the barometric pressure reading 1013.8mb at 08.00, the highest pressure recorded all month.

  • Significant change in wind direction

    Wednesday arrived with ex-storm Sebastien easing eastwards over the country with yet more rain but light winds. The daily rainfall was 4.9mm bringing the monthly total to 108.2mm.

    As the depression traversed the country, initially the wind was from the south but by mid-morning began to back into the east and later in the day was coming from the northwest.

    As a consequence of the cooler air the maximum returned to below average with a peak of 9.6C (-0.5C).

    Overnight cloud meant another mild night but before dawn the cloud cover eased away to the east allowing the thermometer to drop to 6.2C at 08.00 Thursday morning.

  • Fourth successive month with above average rainfall

    Tuesday brought us another 9.2mm of rainfall that brought the monthly total to 103.3mm being almost 12mm above the 35-year average for November. This made it the fourth consecutive above average monthly rainfall and the fourth wettest autumn since records began at this station in 1984.

    Due to the influence of ex-storm Sebastian the mild, tropical air raised the maximum on Tuesday to 12.4C being 2.1C above average. Cloud cover overnight meant another mild night with a minimum of 7.3C at 07.33 Wednesday morning, which was 4C above average.

    Dawn on Wednesday saw the thick cloud easing away to the east leaving thinner cloud and a brighter start to the day that initially produced radiation fog in the River Og valley and some on the tops of the Marlborough Downs.

    The centre of ex-storm Sebastian is currently over central England with a barometric pressure of 981.9mb at 8.00 and beginning to fill.
