The variable sunshine on Saturday boosted the temperature to 20.8C being 1.9C above average even though the very light breeze was from the north. The peak gust of 11mph was the lowest maximum gust since 26th July.
As the temperature dropped steadily overnight to a low of 8.9C, radiation fog formed. The minimum of 8.7C was logged at 05.41 being 0.6C below the average and the coolest night since 6th August (5.8C).
Af first light it was obvious that the fog was thick with visibility limited to less than 200m. However, the sun began to get to work shortly after dawn and by 07.45 there were visible signs of it beginning to thin. By 08.00 the temperature had recovered to 11.7C. The barometric pressure has eased a little higher again with a reading of 1019.5mb at 08.00 so a fine, dry and warm day should be ahead.
