Author: Eric Gilbert

  • Unstable air mass continues

    Monday brought 4.5 hours of warm sunshine that saw the thermometer rise to 15.8C being 1C above the average and the warmest day for almost a week. It was not a completely dry day as a light shower amounted to just 0.3mm.

    An average minimum of 7.2C was reached in the early hours.

    Tuesday dawned with a mostly cloudy sky although there were minor breaks in the cloud cover that allowed a little brightness from time to time. The flow of southwesterly air from the Atlantic continues being a relatively warm and moist airmass.

  • Low pressure in charge again

    After the sunless day on Saturday, Sunday did bring us 1.4 hours of sunshine that meant a sightly warmer day with a maximum of 13.8C, still 0.7C below average even though the breeze was from the south.

    Light rain fell between 1600 and 1640 amounting to 0.7mm that brought the monthly total to 89.8mm, just 4mm above average.

    The past night has again been mild with a low of 10.0C, which was 2.9C above average. The air mass has been humid due to the previous afternoon’s rain and produced misty conditions on Monday morning. Variable weak sunshine broke through after 0800. The low pressure to the north west is influencing our weather with a current barometric pressure of 1014.7mb.

  • Dry but cool again and sunless on Saturday

    Saturday was the fourth day in October that no sunshine was recorded, as a result the temperature by day was depressed with a maximum of only 12.7C being 1.8C below average.

    Thick cloud overnight meant a mild night with the minimum of 9.7C being 2.6C above average.

    Sunday at dawn saw a large bank of cloud easing away to the east with thin cloud exposing possible clear skies to the west. The wind has backed further from the southwest to south. However, barometric pressure has been falling, 9mb down since Saturday, as a cold weather front approaches from the west with possible precipitation later on Sunday.

  • A quieter day on Friday

    Under the ridge of high pressure on Friday we enjoyed much quieter and warmer weather than Thursday as the thermometer rose to 13.0C, however this was still 1.5C below average during the 3.8 hours of limited sunshine. The wind had backed from northwest to west and less strong with a peak gust of 15mph. It was another dry day.

    The temperature fell away to a minimum of 8.3C overnight being 1.2C above average under cloudy skies.

    Friday arrived with total cloud cover after dawn and very calm conditions with the anemometers stationary for many hours after midnight.

    The ridge of high pressure, resulting from the anticyclone centred over Brittany, gave a reading of 1025.7mb at 0800, the highest pressure since the 14th.

  • Northwesterly air steam was cool on Thursday

    The thermometer only reached 11.6C on Thursday as the cool air, brought on a northwesterly breeze, took hold. The maximum was almost 3C below average making it the coolest day since 21st May. However, we did enjoy 6.6 hours of sunshine that out of the breeze felt very warm. t was the twelfth dry day this month.

    With clear skies initially overnight the thermometer fell away to a minimum of 3.5C being 3.6C below average making it the coolest night since 23rd June.

    Friday after dawn saw a bank of cloud easing away to the east with weak sunshine breaking through just after 0800. The barometric pressure has recovered after storm Aurore left the UK having risen 15mb in the past twenty-four hours with a reading at 0800 of 1020.8mb, the highest for a week as a temporary ridge builds over the UK. The breeze has backed into the west and calmed down so no wind chill today.
