Wednesday was the coolest day this month with a maximum of 21.2C just 1.3C above average. Overnight, although just above average (+0.2C), the thermometer fell away to 11.7C at 05.50 making it the second coldest night in August.
There was a heavy dew overnight because of the recent rainfall and low temperature so the ground and surfaces were covered with much moisture.
A short lived ridge of high pressure will give a better day today before the rain and wind arrive from the deep depression slowly closing in on the UK from the Atlantic. The current barometric pressure at the centre of this unseasonably deep depression over the eastern Atlantic is 979mb and still falling, a pressure usually associated with autumn or winter storms.
Rainfall for July currently stands at 7.7mm and evaporation totals 18mm.
