A warm front passed over the area after midday on Tuesday bringing warm, moist air. There was light drizzle at 21.30 and just before midnight and again between 01.00 and 02.00 therefore very brief light showers that in total amounted to 0.4mm.
The temperature extremes were a maximum of 21.4C (+1.2C) and a very warm night with a minimum of 16.4C` that was a significant 6.3C above the 39-year average and the warmest night since 3rd August 2022 with 18.1C. The diurnal range of temperatures, the difference between day and night was thus just 5C.
Wednesday dawned dull and gloomy as the cloud was thick and with a low cloud base that meant it draped over the Marlborough Downs and Savernake Forest producing misty conditions. Later tonight the conditions will change again as another weather front will cross the area, this time a cold front, so a cooler fresher air mass will arrive.
