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, 26th July to 1st August.
Low pressure close to the West coast of the UK and over Ireland and high pressure to the East of the UK over Scandinavia and Northern Europe. The low pressure trough will introduce some rain and risk of thunder. Temperature will remain around 2 to 3 degrees above average for the end of July. Scotland will see above average rainfall. Conditions will start to improve after this weekend.
Week 2, 2nd, August to 8th.
High pressure will be back in control bringing mainly dry conditions with temperature around 3-4 degrees above average for early August.
Week 3-4, 9th August to 22nd.
This is a two week period but it looks like we will start to see a slight change in our weather pattern maybe around the middle of the month. High pressure stretches from the North Atlantic over Northern parts of England and Scotland and onto southern parts of Scandinavia. It will become cooler than we have been use to with the temperatures slipping back to where they should be. Rainfall will be slightly above average from the midlands to the southern parts of the UK with Scotland remaining mostly dry.
