After some warmth in the south and east at first, a cold front will slip south across the UK introducing cooler conditions.
From mid-week onwards a cyclonic west or north-westerly airflow will bring a scattering of showers. Rainfall amounts are expected to be above average for the time of year in the north and west, where it will also be very windy at first.
Sheltered eastern parts of the UK will see normal amounts of rain for the time of year and the best of any brightness. Elsewhere can expect more cloud than sunshine but there will be some sunny spells in between the showers.
Temperatures may get as high as 25C in the southeast at first but by the end of the week this will drop to a a slightly below average 20C for the time of year.
Confidence in the forecast is high for the generally unsettled theme, not so for the detail on cloud amounts and rainfall.
