Weather in December 2019

December was mild and wet but much wetter in the SE and NW of the UK. The CET was 5.80C  which was 0.74c above the long term average. We also had a record-breaking temperature of 18.7c at the end of the month in Scotland. Which means that every season in 2019 had some sort of record broken. Read more on this on the round-up of the year in another blog coming soon.

UK Stats

It was a low pressure dominated month, the Atlantic systems close to the NW of the UK. The jet stream was energised by the extreme cold over the north pole especially high up in the atmosphere.

Looking ahead to January

The continuation of the mild weather during January shows up remarkably in the long term computer models. It could even be another record-breaking month. It is extraordinary to see blossom out already here in Watford. There doesn’t look to be any cold weather with snow in the next 3 weeks. We might have frosts if the high pressure settles above the UK.
