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, 19th September to 25th.

Low pressure just to the West of the UK with High pressure over most of the UK and to the East of Europe. To start off with during this period we will see temperatures around 2-3 degrees above what you would expect for mid September. There will be a change taking place that will bring above average rainfall. This change will start to take place over Sunday and into next week. So this would tell you will have a dry period to start off with becoming very wet later.

Week 2, 26th September to 2nd October.

High pressure just to the West of the UK will bring slightly above average rainfall with temperatures around 1-2 degrees above average. This could be due to a southerly airflow.

Week 3-4, 3rd October to 16th.

This is a two week period and it looks like high pressure will be in control of our weather. Temperatures will be about what you would expect for early October, possibly just slightly below average, with some misty, chilly early mornings. The exception to all this is Scotland that will have above average rainfall.
