Warming up through this period, becoming very warm or hot.
Largely dry and settled. Rather cloudy, although occasional breaks in the cloud will allow for some fine spells. A little breezy near the coasts. A warm night for some otherwise. Minimum temperature 14 °C.
A fine day with light winds and almost uninterrupted sunshine, though it may turn hazy at times. Temperatures will become widely warm or very warm. Maximum temperature 30 °C.
Some cloudy periods on Tuesday, turning sunnier on Wednesday and Thursday, remaining mostly dry throughout. Becoming hot in places as temperatures increase.
Updated:
Northern and western parts may be unsettled at first with heavy rain or thundery showers, before high pressure becomes reestablished. This will continue to bring dry and very warm weather across England and Wales, but always with an ongoing chance of thunderstorms moving in from France. High pressure will likely amplify northwards to bring periods of drier and warmer weather to most of Scotland and Northern Ireland too. Winds will be light to moderate for most, but gusty around any thunderstorms. Temperatures by day will be widely very warm, hot or even very hot in parts of the south. There are signs for the heatwave to ease back to more normal summer temperatures through the next week commencing Monday 13 July.
Updated:
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.
