Author: Eric Gilbert

  • Cool but still above average

    The sunny morning on Thursday lifted the temperature to 11.4C, which was 1.3C above the average. Every day this month has brought an above average maximum. It was a dry day with the UV level rated Low, as expected at this time of year, with a value of 1.0.

    The past night has been cool but the minimum of 5.7C at 07.51 on Friday was also above average (+2.0C).

    Friday brought us a bright start with weak sunshine breaking through just after 08.00. The barometric pressure is rising rapidly as the deep depression eases away, currently centred off the Northumberland coast. As a result of the change in position the wind is forecast to continue from the west until around midday then veer into the west-northwest or northwest.

  • Visitation by very deep low pressure overnight

    A very deep depression moved in from the Atlantic on Wednesday and during the past evening and overnight the centre of the low passed over our area. The barometric pressure at its lowest measured 977.2mb, which was the lowest pressure reading since 20th January 2021 (973.1mb). It was not a record as on 8th November 2010 a pressure of 967.3mb was recorded.

    The passage of the depression meant that during the past evening the wind began to change direction from southeast that was held during the daytime to east at 18.00 then Northeast and Northwest by 23.00. This morning it has settled to come from the west where it will be for most of the day as the depression leaves the east coast and travels into the North Sea.

    The maximum temperature of 10.3C was almost average for November and the lowest since 3rd April, so Autumn has really arrived. The minimum of 7.5C was recorded at 00.22 being 3.8C above the long-term average

    Showers of rain passed over our area during the daytime with a band of rain that started just after midnight to around 03.00 producing 11.0mm of precipitation. That addition brought the monthly total to 86.4mm, which is 3mm below the 38-year average.

    Thursday arrived with a predominantly cloudy sky as the hang back of cloud from the depression slowly moved away.

  • Autumn weather arrives!

    After the numerous days with warm dry day weather, we now are experiencing the weather that we normally associate with autumn. The rain that was heavy all morning on Tuesday ceased just before midday but a further rain band arrived just after 04.30 on Wednesday and ceased just after 06.00 producing 18.7mm of precipitation.The monthly rainfall total is now 75.4mm, which is still 24mm below the 38-year average.

    The cooler air meant that the thermometer only rose to 12.5C, almost the coolest day this month 12.2C on the 3rd, but still 2.4C above the average. The minimum overnight occurred at 03.05 on Wednesday when a low of 6.3C was recorded being 2.6C above the average.

    First light saw the thick, dark cloud of the weather front easing away to the eastern horizon with brightness breaking through just after 07.45.

    The deep depression in the Atlantic,, off the Irish coast, has a very low pressure of just 957mb at midnight. It closeness to the UK has seen the barometric pressure dropping over the past four days with the local pressure at 08.00 reading 991.5mb, the minimum was 990.9mb yesterday.

  • Unsettled weather returns

    The rain returned on Monday afternoon and with a vengeance overnight as a wide and slow moving rain band produced 11.4mm of rain. The monthly total is now 56.7mm but still 32mm below the 38-year average.

    The last of the warm air from the south meant another above average maximum with a peak of 14.9C (+4.8C). Overnight, before the rain band and advance cloud arrived, the thermometer dropped away to 7.8C (+4.2C) at 21.58.

    Rain began shortly after 03.00 early on Tuesday that by daylight had produced the bulk of the rain. By 08.00 the rain had become lighter but still continuous, the temperature having recovered to 11.6C.

    The wind still comes from a southerly quarter with the barometric pressure very low with a reading of 994.0mb at 08.00, a drop of 34mb since the high on Saturday.

  • Cooling down!

    Although we enjoyed many hours of sunshine on Sunday the thermometer fell back from the record warmth on Saturday, with a maximum of 16.2C, still well above average (+6.1C). It was the sixth successive dry day.

    Overnight was also mild with a minimum no lower than 10.1C being 6.4C above the average.

    Monday dawned grey and dull with fog that at first light limited visibility to 400m under calm conditions. The high pressure that gave us settled days recently has been slowly edging away. The barometric pressure today read 1009.8mb at 08.00, down 18mb on the Friday high.
