Monday was the coolest day this month

With a maximum of just 11.3C on Monday it was the coolest day since 28th March being 2.8C below my 40-year average. It felt up to 2.5C colder outside in the very strong northwesterly wind that produced a wind chill, often gusting in excess of 30 mph with a peak gust of 39mph. There were the occasional brief rain squalls that amounted to 2.6mm of precipitation with small hail falling at 14.40. At that time the air temperature dropped from 10.4C to 8C.

The past night saw an above average minimum if 6.8C at 06.39 early Tuesday being 3.1C above the long-term average.

There was the odd flicker of brightness early Tuesday with longer spells of sunshine just before 08.00 that had lifted the temperature to 9.1C by 08.00.

The recent depression is now heading eastwards over Germany and we are coming under the influence of a high pressure in the Atlantic. The barometric pressure at 08.00 read 1014.1mb, up 8mb since Monday. The anticlockwise circulation of air associated with the depression and the clockwise circulation linked to the anticyclone is still streaming strong winds from a northwesterly direction, but not as strong as on Monday. This will continue into Wednesday.
