Wind chill on Monday morning!

The wind did increase in strength Sunday afternoon and overnight, as forecast, with a peak gust of 33mph at 05.20 Monday morning. The temperature at 08.00 on Monday was 4.2C but due to the strength and direction of the wind, a cool northerly, a wind chill meant it felt more like -0.1C at that time outside.

The maximum of 6.8C on Sunday made it the coolest day since the 7th (5.5C) being 1.3C below my 40-year average. Irrespective of the strong north northeasterly overnight the cloud cover meant a low of 4.1C at 07.30 Monday was 2.4C above my 40-year average. Not only the cloud limited the loss of warmth into the atmosphere, acting as a blanket, but the wind kept the air constantly on the move. The rainfall for the past twenty four hours measured 7.7mm that took the monthly total to 139.3mm, which is 212% of my 40-year average.

The low pressure system that caused the rain and wind over the past twenty-four hours has now moved across to the near Continent. As it continues to move further away the barometric pressure will continue to rise rapidly. This will also be due to an intense high-pressure system mid-Atlantic that is producing a temporary ridge of high pressure over the UK on Monday helping to funnel the strong wind down from the north between the clockwise rotating air mass of the high pressure and anticlockwise low pressure systems. The air is much drier this morning reading 88% at 08.00, the driest air flow this month.
