The evidence of the departure of our almost resident anticyclone was noted as the barometric pressure began to fall steadily in the past twenty-four hours with the muted sunshine obscured in the afternoon as cloud drifted from the south.
The thermometer rose to 15.5C in the daytime, 5C above average, but did not drop below 9.1C overnight thanks to the thick cloud that arrived providing a duvet to keep residual warmth. This low was 6.8C above the average giving the warmest start to a day at 08.00 since 22nd February.
Tuesday early saw light drizzle that was not measurable, and thick, low cloud. The barometric pressure has dropped 23mb since its peak with a reading at 08.00 of 1012.9mb.
