Tuesday saw the thermometer rise to a maximum of 22.2C at 14.20, which was 3.6C above the 34-year September average.
However, early afternoon the wind began to veer from the southwest into the west that saw the temperature begin to fall steadily for 18 hours. This was compounded by the wind backing again, then into the north, after midnight.
There was light rain and drizzle for much of the evening and another burst just before 4am, amounting to 3.5mm, the wettest day since 26th August.
By 06.56 the thermometer had reached it’s lowest point with a reading of 10.5C, which was 1.2C above average.
Wednesday arrived with the back edge of the first weather front easing away to the east with skies beginning to brighten, before second front traverses the area mid-morning.
Wednesday update at 16.20: maximum temperature of 14.6C at 14.25 down significant 8C on the Tuesday peak due to cloud from dual weather fronts and northerly breeze.
