Rain in an Anticyclone

I thought my aneroid barometer was telling very big porky pies this afternoon whilst I was watching the rain and drizzle fall.

A mild, damp, murky, misty day with 2.6 mm of rain and an air pressure of 1036 hPa (and currently rising).

With the hills shrouded in mist and light rain, you could be forgiven for thinking we are in a warm sector of a low pressure system with an air pressure of 992 hPa rather than in a strong anticyclone. The lack of wind is the only thing giving it away at the moment.

The Winter Cold Spell

There were dozens of Met office warnings aimed at this area of Devon for Thursday (12th January); everyone got excited at the prospect of snow. There was an awful lot of staring out of the office windows willing the rain to turn to snow despite a temperature stuck at 7°C with a dew point at 6°C – no chance.

The rain was quite extensive on Thursday with a rainfall total of nearly 20 mm for the whole event. The temperature only really started to drop away in the evening after the rain had stopped. Then the stars and moon shined through the clearest of skies into Friday with a minimum of +1.5°C and a bitter wind ensued. The maximum even with 7 hours of sunshine was 6.9°C, making it one of the coldest day maximums of the winter so far, so yes – a taste of ‘winter’.

Then Saturday arrived with a very sharp frost (for here) of -2.6°C. But it didn’t take long for the wind to soften and the temperature to rise smartly in the sunshine with the maximum eventually reaching a balmy(ish) 10.4°C and the wind mellowed by a dew point of 6°C.

The “cold blast” lasted all of 24 hours and apart from a few hours of a rather unpleasantly bitter wind, no snow/sleet fell.

Today (Sunday), all back to normal…..

15th January (mid-winter’s day?)
Minimum = 5.2°C
Maximum = 10.4°C
Rain = 0.0 mm
Sunshine = 0.1 hours (unfortunately it was a cloudy ol’ day with just brief spells of brightness).
