UK long range weather forecast

High pressure is likely to remain close to the UK into this period, and likely centred to the west or northwest of the country. This means plenty more dry weather for most if not all parts, though with the source region of the air being the North Atlantic, somewhat cooler, or at least less hot, conditions are expected, compared to many recent days. Towards the latter part of July, the influence of high pressure may wane somewhat, allowing a greater chance of rain, showers or thunderstorms compared to earlier in the month. Overall, temperatures are expected to remain above average during this period.
