  • Storm Callum skirts the area

    Although we have been on the periphery of storm Callum the effects were felt and seen as Thursday gave us much more cloud with little sunshine, just 0.53 hours and a breezy, dry day.

    The warmth was reduced from the peak on Wednesday, a drop of 4.5C, although a maximum of 17.9C was still 3.2C above the average.

    Thick cloud overnight and the southerly warm air flow meant another mild night. Interestingly, the thermometer fell to its lowest point at 00.23 this morning with a minimum of 12.1C, being 4.1C above average. Thereafter the temperature slowly rose again to reach 14.4C at 08.00 when readings were taken.

    Another feature of our closeness to the storm was that since just after midnight the wind strength has been increasing with a maximum gust of 33mph at 06.49 this morning.

    Light rain showers commenced just before 5am with little quantity so that by 08.00 only 0.7mm had fallen.

    Update on Friday at 17.50: Storm Callum felt as winds blow strongly all day with a peak gust of 40mph at 15.41. The air, still coming from mid-Atlantic, raised temperatures to a maximum of 18.1C late in the afternoon at 16.36, which was 3.4C above average.

  • July temperatures in October! Low barometric pressure indicates storm Callum is approaching.

    Wednesday saw the thermometer rise to a maximum of 22.4C at 15.53 under the influence of a very warm air mass brought from the Continent on a south to southeast breeze. This was 7.7C above the 34-year October average, the warmest day since 17th September and the warmest October day since 1st October 2011, which reached 26.7C. The peak was 0.15C above the July average maximum temperature.

    It was another dry day with the UV level firmly in the Low category even though we had 6.8 hours of strong sunshine.

    Cloud cover overnight combined with the warm air mass meant another above average night with the thermometer slowly sinking to reach a minimum 13.9C at 07.20 this morning. This was 6.5C above the average and the warmest night since 20th September.

    Thursday dawned with variable cloud as a cloud bank moved eastwards.

    The barometric pressure is at it lowest this month, a minimum of 1000.1mb, as storm Callum moves in from the Atlantic but tracking towards the north of the UK.

    Update on Thursday at 16.35: first rain began to fall at 16.30 from first weather front crossing the area after another mild day with a maximum of 17.9C, which was down 4.5C from the peak of yesterday but still 3.2C above average. Gusting wind during afternoon with a peak of 26mph.

  • Southerly air boosts temperatures

    With the high pressure easing away to the east on Tuesday it allowed the wind to back further, then from the south. This southerly wind brought dry warm air from the continent and the Mediterranean producing a maximum of 19.7C, which was 5C above average making it the warmest day this month and 4C up on the Monday high.

    It was another dry day with the UV level dropping into the Low category.

    Another mild night followed with the thermometer falling slowly to a minimum of 8.7C being also above average (+1.3C)

    Wednesday arrived with fog limiting visibility initially down to 1,500m but hazy sunshine from dawn soon began to improve the visibility.

    Update on Wednesday at 16.35: continental air pushes temperature to a maximum of 22.4C at 15.53 making it the warmest day since 17th September. This was 5.7C above average and equal to a July average maximum also the warmest October day since 1st October 2011.

  • South westerlies bring back some warmth

    Monday saw the wind back from the north into the south west, a warmer if moister air. As a consequence the thermometer rose above average with a maximum of 15.5C (+0.8C).

    It was breezy day with little sunshine, 0.8 hours, and the UV level just in the Moderate category.

    With variable cloud it was a mild night with the thermometer not dropping below 9.6C, again above average (+2.3C) and some 7C warmer than the previous chi night.

    Tuesday has dawned with a mainly clear sky and weak sunshine.

    Update on Tuesday:warm, continental air raises temperature to a maximum of 19.7C at 14.59, which was 5C above average. Blue skies all day produce almost 11 hours of strong sunshine.

  • Sunshine returns on Sunday

    After the washout day on Saturday the sun returned on Sunday bringing us 7.5 hours. Although there was a very light breeze from the north, maxima gust of 7mph, the temperature recovered from the previous days minimum reaching 12.7C, which was 2C below average.

    Sunday was dry, the sixth this month.

    Overnight cloud meant a mild night with a minimum of 9.7C.

    Monday arrived with a cloudy sky and no sunshine.
