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, 24th May to 30th.

The JMA is showing high pressure over the southern parts of the UK with the centre towards the Azores and low pressure over northern parts of the UK. For ourselves the temperature and rainfall will be around average. The first few days the first few days of this period will be dry. Rain and showers from the middle to the end of the month. Scotland is looking wet with above average rainfall.

Week 2, 31st May to 6th June.

High pressure is located over Southern parts of the UK stretching northwards over the midlands. I think we will see a south-westerly airflow this will bring some showers, but overall rainfall is around average with temperatures into the high teens.

Week 3-4, 7th June to 20th.

This is showing fairly slack pressures. Rainfall is looking slightly above average so it could be quite showery. Air temperatures may be 1 or 2 degrees above average for early June.
