The wind on Wednesday backed a few degrees into the southwest, also less strong, that with 6.3 hours of sunshine allowed the thermometer to rise to 21.3C. This was still 1.4C below average, in fact we have only enjoyed one day this month when the maximum was above average due to the changeable weather.
Wednesday saw lines of heavy, thundery showers moving southwest to northeast across the west country and up into the Midlands. These were to the west of this area, bar one, that grazed Marlborough and brought us a very brief, heavy shower amounting to 0.6mm. I noted late afternoon a continuous line of heavy showers stretching from South Devon to Gloucestershire.
The overnight minimum of 12.5C was 0.7C above average due once again to the thick cloud cover.
Thursday arrived sunless due to the continuing total cloud cover. The wind at 0800 had dropped out completely as the high pressure began to exert its presence with a pressure of 1019.4mb, the highest this month.
