Outlook for Tuesday to Thursday:

Tuesday will be cloudier, perhaps with the odd shower. Dry with some sunshine on Wednesday and Thursday, though a brisk wind developing, making it feel rather cool.

High pressure is likely to be centred close to or across the UK through much of this period. So many places will be largely dry with clear or sunny periods. Colder air will try to push into the country from the north toward next weekend, but will probably only make limited progress into the northeast for a brief time, where it could bring a short lived showery interlude, some of these wintry. Winds will be mostly light, but briefly stronger in the northeast as that colder air tries to come south. Temperatures will probably be near normal or slightly above for many, but with a risk of colder conditions affecting the north next weekend.

Slowly evolving weather patterns are likely through the first half of May. Within this, high pressure is likely to be located somewhere to the north or northwest and low pressure closer to southern areas. The orientation of and proximity to the UK of each of these features will be key to regional weather on a day-to-day basis. However, on balance, northern and some western areas are likely be drier, with southern and possibly some eastern parts seeing more in the way of rain or showers. Overall, temperatures probably close to or a little above average, though scope for some cold nights with late season frost, especially in the north.
