The GEFS thinks there will be a cooling off in temperatures and it will become wetter next week.
A quick look at the graph shows some spikes at the bottom of the graph on Saturday 27th, I think these will be some showers possible thundery during the daytime. Sunday 28th looks dry. Then some rain Bank holiday Monday 29th.
From early next week the temperate declines and it becomes unsettled with rain and showers every day.
Please note this is a general outlook and is not meant to be a forecast.
