Radiation fog after very cool day and night

Friday produced a couple of showers midday and then early evening amounting to 1.9mm being the ninth consecutive day with measurable rainfall.

The wind having veered into the northwest pegged back the temperature, that combined with reduced sunshine of 4.31 hours meant a cooler day again, 2C down on thursday. The thermometer peaked at 13.51 with a maximum of just 14.3C, which was 4.4C below the 33-year average. This was the coolest day since 9th May

With predominantly clear skies the temperature dropped consistency overnight producing a minimum of 5.4C, some 4C below the September average. As a result of the moisture and very low temperatures radiation fog formed again in the River Og valley.

There was intermittent sun after dawn that by 07.45 had dispersed the fogged slowly beginning to raise the temperature so that at 08.00 the thermometer read 6.7C, the coolest morning since 29th April.
