The start of the week will be fine and dry with sunny spells for many in England and Wales.

However, a series of weak fronts will push into Scotland and Northern Ireland bringing cloudier weather here with a chance of some light rain, especially across the northwest.

From Wednesday onwards while cloud, rain and breezy conditions continue across the northwest, it will become increasingly warm in the south as high pressure builds.

This will bring settled conditions allowing temperatures to build day-on-day and for it to become warm, or even hot, for a time by Friday.

Met Office Deputy Chief Meteorologist, Dan Rudman, said; “Temperatures will continue to rise as we go through the week, becoming well above-average by Friday when many parts of the southern half of the UK are likely to exceed 30C and may even reach 34C in some places.”

“This is the first spell of hot weather this year and it is unusual for temperature to exceed these values in June. Many areas will also see some warm nights with minimum temperatures expected to be in the high teens or even low 20Cs for some overnight.”

“The heat is a result of a mix of home-grown warming in the day due to high pressure, as well as a southerly airflow introducing some of the warm air from the continent to UK shores.”

A Level 2 Heat-Health Alert has been issued for the much of southern and central England, with a Level 1 Alert in place for northern England.

Agostinho Sousa, Head of Extreme Events and Health Protection at the UK Health Security Agency, said: “Temperatures are forecast to reach 30C in some parts of the south on Friday and we want everyone to enjoy the hot weather safely when it arrives and be aware of good health advice for coping with warmer conditions.

“During periods of hot weather it is especially important to keep checking on those who are most vulnerable, such as older people and those with heart or lung conditions. Make sure to look out for signs of heat exhaustion and follow our simple health advice to beat the heat.”
