This is the outlook for the next four weeks using the JMA model. It’s not a forecast but a general outlook from the JMA issued by the Japanese Met Agency
Week 1 29th June to 5th July.
Low pressure with a trough sitting over the UK is in control. This will bring mainly mixed to unsettled weather with plenty of rainfall.
Week 2 6th to 12th July.
High pressure to the south of the UK and low pressure to the North of the UK. This will bring drier weather with some showers at times.
Week 3 and 4 13th July to 26th.
High pressure ridge to the South of the UK. I see this period becoming mainly dry with some warm days.
