UK weather

Headline:

Rain in the north, hot and sunny in the south.

This Evening and Tonight:

A rather breezy night in the north with occasional rain, heaviest in northwest Scotland. Low cloud and hill fog redevelop across southwest Britain and western areas of Wales. Elsewhere, fine and dry with clear spells and rather mild.

Tuesday:

Further rain or showers affect northern areas, though generally less heavy. Cloudy in Northern Ireland and northwest England with patchy drizzle. Elsewhere dry and sunny, feeling very warm to hot.

Outlook for Wednesday to Friday:

Cloudy and patchy rain start clearing western Scotland on Wednesday. Then generally fine and dry with light winds and plenty of sunny spells. Very warm, staying hot in the south.

Southern areas are likely to start this period hot, with heatwave conditions persisting. To the north, an Atlantic frontal zone will introduce somewhat cooler conditions, with the potential for scattered thunderstorms to develop just ahead of this. Into the following week, high pressure is likely to build to the north or northwest of the UK, though its exact orientation is rather more uncertain. This would bring a lot of dry weather for many areas, though perhaps an increased chance, relatively to previous days, of showers or thunderstorms in the south. Temperatures probably moderating a little, though remaining above average for many areas.

High pressure is more likely than low pressure for the rest of July, probably bringing settled and drier conditions. Occasionally this dry and warm weather could be interrupted by outbreaks of rain and stronger winds, which will be more probable in the north or west. As is typical for the time of year, there is a risk of heavy, thundery showers during any warm spells. These conditions are likely to persist through to the start of August, with unsettled interruptions perhaps becoming more common, but confidence at this range is low. In any case, temperatures are likely to be above average overall, with a greater than normal chance of hot conditions developing at times, especially in the south.
