  • Highest barometric pressure this month bodes well

    Wednesday brought another dull with much dampness but little precipitation, just 0.6mm.

    Although it was a cloudy day, with a little brightness late in the afternoon, the peak temperature was average at 18.7C.

    A mild night followed with a minimum of 12.8C being 3.6C above average.

    Initially Thursday arrived with hang back of cloud from the weather front that lingered around on Wednesday but just after 08.00 there were glimpses of weak sunshine.

    The barometric pressure currently is registering 1026.3mb, the highest since 21st August, which indicates drier and brighter weather ahead.

  • Temperatures recover on Tuesday

    With a little sun returning (3.9 hours) on Tuesday the temperature was higher than on Monday with a maximum of 18.1C late in the afternoon, but this was still 0.5C below average.

    It was a dry day with the UV back into the ‘high’ category after being ‘low’ during the rainy Monday.

    A mild night was to follow with the thermometer not sinking below 10.1C, which was 1C above average due to cloud cover.

    Wednesday dawned with continuous cloud cover and, after a still night, the wind beginning to pick up.

  • What a dismal day on Monday!

    With no sunshine and almost continuous drizzle or very light rain, Monday was a depressing day. The total rainfall after hours of minimal precipitation was just 1.6mm that did nothing to replenish my six rainwater buts.

    Not only was Monday a wet day the temperature was depressed with the thermometer struggling to reach a maximum of 14.0C, which was 4.6C below average and the coldest day since 17th May.

    The minimum overnight was also below average with a low of 8.8C (-0.4C).

    Fog formed in the early hours limiting visibility to 400m. By 07.15 the sun was just visible through the cloud and fog but not until 08.30 was there any strength in its rays as the fog evaporated.

    Today will see the wind direction change from a southerly to north westerly as air flows clockwise around the high pressure to the west of the UK.

  • Temperatures recover a little – but still below average

    The maximum on Sunday was up 1C on the Saturday high but at 17.7C was 0.9C below average. The light air flow from the north tempered the warmth from the 8.5 hours of sunshine.

    We had another dry day with rainfall for September minimal at 3.6mm with evaporation now totalling 18mm.

    The past night was just above average at 9.6C but significantly,higher than the very low of 0.9C recorded during the early hours of Sunday

    Monday dawned with thickening cloud from an approaching weather front as the barometric pressure is at its lowest this month with a current reading of 1012.6mb having fallen for the past 30 hours. The first raindrops were noted at 08.10 from the first rain band that weakened and fragmented as it moved in from the west. The more active front will follow later this morning.

  • Ground frost – that is cold for early September

    Another day on Saturday with below average temperatures due to the northerly air flow called Polar Maritime originating around the Iceland area. The thermometer struggled to reach a maximum of 16.7C at 15.49 being almost 2C below average.

    Clear skies overnight saw the thermometer plunge to a minimum of 0.9C at 06.33 Sunday morning giving a ground frost, which was 8.3C below average and unusually cold for early September, thanks again to the northerly air flow.

    At 06.37 the first glimpse of the sun could be seen rising over the horizon and since then has been shining strongly lifting the temperature to 5.3C at 08.00. This made it the coldest start to a day since 5th May (2.6C).

    The barometric pressure is currently the highest this month at 1025.4mb
