Thursday saw the thermometer climb above the average again with a peak of 25.0C (+2.3C) probably being the last day of real summer this year as the high pressure has now moved away and low pressure is again in charge for the foreseeable future. The wind was again light with the UV level again High.

It has been a cool night under clear skies with a low of 8.1C being 3.7C below the 39-year average.

Friday initially brought us a gloriously sunny start to the day but just before 08.00 cloud began to drift across and shortly afterwards the sun became totally obscured. The wind is forecast to back a few degrees coming from the westsouthwest and later southwest, still light in strength.

The many hours of strong sunshine on Wednesday lifted the temperature to 26.0C. This was the warmest day since 7th July (27.9C) and 3.3C above the average. It was a dry day making it the longest dry period, even so only five consecutive days, since the end of June.

Thin cloud began to drift across the sky late afternoon that thickened overnight and gave us another mild night with low of 14.0C, which was 2.2C above the average.

Thursday dawned dull with total cloud cover and no sunshine thanks to low pressure systems to the south and north of the UK. The barometric pressure at 08.00 read 1013.9mb, a drop of 8mb since Wednesday. There has been total lack of breeze since midnight but when it does resume, it will be light and will have veered from the southwest into the west and later today the northwest, therefore cooler weather in the forecast.

Tuesday gave us a sunny day, especially in the afternoon, when it was almost continuous lifting the thermometer to 23.3C (+0.6C). The UV level was 6.6, which is at the top end of High. The past not was the coolest in a week with a low of 10.C being 1.1C below the average.

Wednesday arrived with fog that intensified up to 07.00, limiting visibility to 200m. However as the clock turned 07.00 the sun began to rise above the fog bank and disperse the thinning fog. The barometric pressure (1021.6mb at 08.00) resulting from the High over the Continent will shortly being leaving us as further depressions gang up on us from the Atlantic, so probably this will be the last of the very sunny days for a while.

Monday brought us variable sunshine that was strong at times with the UV level up to the Very High category again. Anther day, rare this month, when both the maximum of 23.0C (+0.3C) and the minimum of 14.3C (+2.5C) were above average.

Tuesday revealed a cloudy start to the day with the high pressure beginning to ebb away, down 3mb since Monday. However, once the cloud begins to thin it should be another warm and dry day. The light southwesterly of recent days is forecast to veer into the west.

The sun was strong on Sunday, if intermittent, that pushed the thermometer to 23.9C being 1.3C above the average. Cloud cover overnight produced another mild night with a low of 13.8C, which was 2.0C above the average. The UV level of 7.5 was back into the Very High category, not reached for over a week.

Monday revealed a mainly cloudy sky with the occasional bursts of sunshine. The ridge of high pressure has been building further with a reading of 1024.5mb at 08.00, the highest pressure since 24th June.The southwesterly air movement continues, a mild, moist airstream.

Whilst our Storm Betty has now dissipated, in mid-atlantic three tropical storms are forming, namely Emily, Franklin and Gert, in addition to that currently attacking California.
