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, 8th 7th May to 13th.
The UK looks to between low pressures and high pressure areas. It looks like rainfall will be around average, feeling cool with below average temperatures.
Week 2, 14th May to 20th.
Low pressure system over the Atlantic and Western and central parts of the UK. This would bring above average rainfall so showers and longer spells of rain. The temperature looks to be around average.
Week 3, 21st May to 3rd June.
Slack air pressure over the UK will bring around average rainfall with temperatures around average.
