UK long range weather forecast
Patchy cloud and sunny spells on Monday with the south staying largely dry. Showers are possible elsewhere however, especially in the north and northwest where there will be a cool breeze also. Most areas will be mostly dry into the middle of next week, beyond which it is likely that the settled conditions will continue for many central and southern areas, bringing dry weather and sunny spells here. Northern and northwestern parts will probably turn increasingly unsettled with spells of rain accompanied by stronger winds at times. Later in the period there is a chance that the unsettled conditions across the north may spread more widely across the rest of the UK. Temperatures near or slightly above average but perhaps warm or at times very warm in the south.
Updated:
Through the end of July and into August many parts of UK are likely to see periods of drier and settled weather, most especially in the south. These settled periods however will be interspersed with spells of wet weather with winds becoming stronger at times. These spells of wind and rain will largely be across the north and west of the UK but will often spread to other areas. Temperatures sticking around normal with any warmer weather being short-lived and most likely in the south.
