Outlook for the next four weeks from the JMA.

Outlook for the next four weeks from the JMA.


This is the outlook for the next four weeks using the JMA issued by the Japanese Met Agency. This is just one model the JMA but followers will know that I normally publish it every Thursday or Friday. I have added the three images together and I have rotated them and added a red line so you can see the UK. Blue colours are low pressure areas and orange’s colours are high pressure areas.

Week 1 4th October to 10th.

High pressure is over central Europe with a deep low pressure trough over the Atlantic and close to the West coast of the UK.  This will bring above average rainfall and temperatures slightly below average.

Week 2 11th October to 17th.

High pressure is in control stretching from the Azores over the UK and onto Scandinavia. This will bring a warm feel with temperatures 1 or 2 degrees above average. But with the high pressure bringing a South westerly airflow we will see rainfall slightly above average.

Week 3, 4  18th October to 31st.

Low pressure from the midlands northwards with a small high pressure system to the South of the UK. This looks like being a cold period with temperatures around 2 or 3 degrees below average. Rainfall will be around average except for Northern England and Scotland bringing a wet period with above average rainfall.
