After a dry and warm day on Wednesday, with a peak temperature of 19.8C being 2.3C above average, the disturbed weather from France crossed the Channel in the evening. The first rain was observed at 21.15 and became very intense at 22.00 as violent storms with numerous claps of thunder and flashes of lightning continued until just before 22.30.
The lighting radar showed a number of storm locations just to the north and east of Marlborough trailing back across southern England and across the Channel where they were numerous.
For the second consecutive day the UV level rose to 7.0, which was just in the ‘Very High’ category.
The rainfall amounted to 10.9mm that brought the monthly total 42.0mm being 18mm below the 38-year average.
The thick cloud overnight meant another mild night with the thermometer not dropping below 10.1C, which was 3.7C above the average.
Thursday morning began with total cloud cover but just after 08.20 bright periods were beginning to appear.
