Windrush Weather

Author: Eric Gilbert

  • Ground frost again as on Tuesday morning

    Tuesday produced a little sunshine, just 2.8 hours but again the strong westerly wind, gusting to 26mph, pegged back the temperature to a peak of 7.8C, being 2.3C below average.

    A brief shower during the morning produced 0.3mm of precipitation.

    With the air temperature dropping away to 2.5C early Wednesday a ground frost occurred, briefly.

    The barometric pressure continues to yo-yo as depressions cross the country followed by very brief ridges of higher pressure.

  • Below average temperatures continue

    With 4.6 hours on Monday it was a much improved day with just a light shower amounting to 0.2mm.

    Temperatures by day and night were depressed with a maximum of 9.1C, which was 1C below average. This was the sixth consecutive below average daytime temperature. The minimum was also 1C below average with a recording of 2.8C early Tuesday morning.

    The wind is frequently changing direction as the depressions arrive and traverse our country, often moving 180* during the course of one day. Yesterday brought a brisk westerly breeze gusting to 21mph.

    Tuesday arrived with a mostly clear sky and much sunshine.

  • A brief respite on Sunday before overnight rain again

    After the clearance of overnight cloud on Sunday morning the sun came out and the wind abated when we enjoyed 3.6 hours of sunshine.

    During the late afternoon the thermometer fell to its lowest point, usually the highest during daylight hours, with a reading of 3.0C at 18.02 before beginning to rise again as more cloud drifted in from yet another rain band.

    During the early hours the temperature rose again to around 7C with strong winds and a squall at 04.14 Monday morning when the wind gusted to 26mph as the barometric pressure reached a minimum and thence began to climb again.

    The overnight rain amounted to 4.2mm bringing the monthly total to 58.5mm. This followed the wettest day in November on Saturday with 21.8mm. Currently this is the fifth wettest Autumn I have recorded since the station was set up in 1984, but there are still 20 days to go in November!

  • Coldest day in seven months on Saturday

    After a dry start to Saturday the next rain band arrived with the first spots of rain falling at 10.55. This extensive rain band, extending from the Outer Hebrides to Northern France was over 120 miles wide. Thereafter the rain fell steadily and continuously for almost seven hours with occasional showers overnight. The rainfall total for the past twenty-four hours amounted to 21.8mm, which brought the November total to 57.3mm.

    Saturday was a cold day due to the brisk wind that started from the southeast in the morning and in the late afternoon backed 180* into the northwest. The maximum temperature was just 5.7C, which was 4.4C below the 35-year average and the coldest day since 4th April.

    Overnight the temperature was stable around 5C. As the low pressure system, having been reluctant to leave our shores, migrated into the English Channel on Sunday morning the wind veered back into the Northeast and freshened giving a wind chill so that at dawn it felt more like 3C than 5C. Thankfully the rain had stopped.

  • Rain, sun and frost – all in one day!

    The hang back of cloud from the depression that was emigrating to the North Sea meant rain for a couple of hours on Friday morning producing 1.9mm. By mid-morning it had brightened but the north westerly breeze meant a cool day with the thermometer not rising above 7.4C, which was 2.7C below average.

    The barometric pressure was rising throughout Friday reaching ts highest this month with a reading of 1-12.8mb at 01.06 Saturday morning. This resulted in a clear sky overnight that allowed an air frost to form dipping to -1.9C, which was 5.7C below average, at 05.24 Saturday.

    Cloud from yet another depression and approaching weather front then began to filter across the sky blocking out the initial brightness.
