JANUARY 2020

The mild, mainly settled overcast conditions at the end of 2019 continued into 2020 and, apart from a brief period of rain overnight 2nd/3rd, lasted until 7th. Daytime temperatures reached around 10°C and nights fell between 5.3°C and 7.4°C.

From 8th a series of low-pressure frontal systems passed through, depositing some rain on most days until 16th. The most significant amounts were 16mm on 14th, 8.9mm on 16th and 9mm on 13th. The temperatures during this period were generally in double figures, with a maximum of 13.0°C on 14th, and nights only falling to around 5°C or 6°C, apart from 6th when it only fell to 9.1°C the mildest night of the month.

An anticyclone moved in on 18th and brought record high pressures with a peak on 19th. Clear nights and light winds brought night temperatures down to below the previous 5°C-6°C with three air frosts and one ground frost including a minimum for the month of -1.7°C on 21st. The few sunny days were cooler than of late, around 6.0°C. With the very light winds early fog, overcast conditions and drizzle developed.

By 25th the anticyclone had moved away and bands of light rain totalling 9.6mm over three days passed through. The barometer had fallen rapidly and by 27th was at a minimum for the month, a drop of 1.5" (50mb). A couple of calm, clear days were followed on 30th - 31st by more showery weather and daytime temperatures of 11.5°C & 12.5°C.
