Windrush Weather

Author: Eric Gilbert

  • All change from sun and blue skies yesterday to cloud and rain today

    Monday provided us with 7.27 hours of strong sunshine making it the sunniest day for almost a fortnight. As a result of the sunshine and the wind coming from the southwest rather then the west, the temperature recovered a little to a maximum of 10.9C. being 0.9C above the November average.

    The leading cloud from the approaching weather front meant that although the thermometer dropped to a low of 5.7C around 5.30pm, after that it recovered and rose 4C in the evening.

    By 08.00 this morning the thermometer read 9.8C as the cloud was thick and low just ahead of the forecast rain.

  • Temperatures plummet

    Sunday:

    Maximum of 9.4C, which was the lowest since 1st March and 0.6C below average
    Minimum of -2.1C, which was the coldest night since 27th April and 5.8C below the 33-year average
    UV level at 1.1, which was the lowest since 22nd February
    Soil temperature at a depth of 5cm read 2.1C at 08.00, which was the lowest since 28th February
    Temperature at 08.00 this morning was -1.7C, which was the coldest morning since 6th February
    Barometric Pressure at 08.00 this morning reading 1026.1mb, which was the highest pressure since 31st October

    However, we did have 5.67 hours of strong sunshine, making it the sunniest day since 30th October.

    Due to the ridge of high pressure, that has been building for the past 36 hours, we enjoyed clear skies at dawn with continuous sunshine.

  • Sunshine down, temperature down but wind strength up

    Saturday brought just 0.55 hours of strong sunshine. The limited sunshine and wind, gusting to 18mph, from a cooler westerly direction, meant a cooler day with a maximum of 12.0C, still 2C above the 33-year average.

    Overnight, the clear skies meant a cold night with a minimum of 1.9C, almost 2C below average producing a ground frost.

    This morning dawned bright with strong sunshine shortly after the sun rose above the horizon.

  • Wettest day for three months

    Friday was a dry day with limited sunshine, a total of 2.1 hours of strong sunshine was recorded. The daytime temperature fell away again for the third day with a maximum of 12.8C, still 2.8C above the November average.

    The temperature dropped away to a low of 9.9C during the afternoon and early evening but just after 9pm the thermometer started to rise again as the cloud, associated with the approaching weather front, arrived so that that at 08.00 this morning the thermometer read 11.9C, the mildest start to a day for a week.

    There was little wind during the daytime yesterday, maximum gust of just 7mph. However, after midnight as the weather front started to pass over the area, for a few hours there was more wind activity with a maximum gust of 14mph.

    The rainfall over the past twenty-four hours, to 08.00 this morning, totalled 12.7mm, the wettest day since 2nd August. It is still raining this morning with low cloud draping the Marlborough Downs giving very misty conditions.

  • More sun and more thick fog in very still conditions.

    The sun eventually got to work on the fog on Thursday morning and gave us 4.3 hours of strong sunshine that pushed the thermometer, again, above the average with a maximum 13.5C (+3.5C).

    The high barometric pressure had reduced 5mb, as the centre of pressure drifted southwards, but still gave exceptionally still conditions with one maximum gust of just 6mph. I had to go back through the records to find a day with even less wind and that was on the 18th January 2017 when the strongest movement of air was 5mph.

    Last night was a repeat of the previous night as the clear skies and still conditions caused fog to form again with visibility even further reduced and down to 90m at dawn.

    The thermometer fell away as expected in clear skies overnight to a minimum 4.9C, recovering as the fog formed to 6.9C at 08.00.
