The outlook for the next four weeks is showing the UK will be mainly under low pressure with no sign of summer like weather.
The JMA is issued from the Japanese Met Agency, I believe the JMA to be a good signal to a general outlook for the next four week period.
Looking at the JMA images you can see I have pasted them together and rotated them and add a red line so you can see the UK.
It shows the UK will be under mainly low pressure with a trough over the UK. This will bring mainly mixed conditions with plenty of showers around and temperatures just below average during the next four week. Yes we will have some dry day with some sunshine but overall mixed to unsettled condition prevail
