This is the latest outlook for the next four weeks from the Japanese Met Agency the JMA. It is not meant to be a forecast but a general outlook. I have added the 3 images together and rotated them and added a red line so you can see the UK. Blue colours are low pressure area’s and oranges high pressure area’s.
Week 1, 14th -20th.
Low pressure is firmly in control with a deep trough over the UK. This will bring unsettled spell of weather with above average rainfall with the temperature around 2-4 degrees below average so it will be very chilly.
Week 2, 21st – 27th.
Low pressure will be in control of our weather. This period will see above average rainfall. There will be a south westerly airflow off the Atlantic so the temperature will be 2-3 degrees above average.
Week 3-4, 28th November to 11th December.
Low pressure is to the North West of the UK and High pressure to the South UK. This setup will bring a westerly airflow off the Atlantic bringing slightly above average rainfall so very showery and the temperature will be 1-2 degrees above average.
