Tropical Storm Debby bringing unexpected weather to UK - see the forecast

Tropical Storm Debby is having a major impact on the UK's weather this weekend.

A hot summer's day will be stopped by thunderstorms over the course of the weekend, as Tropical Storm Debby in North America helps to strengthen the jet stream. Cloud and patchy rain will affect parts of England and Wales on Saturday (August 10), but it will remain dry with some warm sunny spells in the far southeast. It will be brighter further north with scattered showers continuing.

Heat and humidity will take over from Sunday, when the Met Office expects to see temperatures increasing, particularly in the south and east. But a bright, hot spell on Sunday will be put to an end by thunderstorms, warns the Met Office.

Met Office Deputy Chief Meteorologist, Dan Holley, said: “We expect to see a relatively brief hotter and more humid spell of weather for Sunday and Monday, before these hotter conditions recede on Tuesday, allowing more unsettled conditions to return.

“This change to hotter conditions is caused, in part, by the effects of Tropical Storm Debby in North America. Debby is helping to strengthen the jet stream, causing it to meander over the Atlantic. This will allow hot air over France to move into the UK later this weekend, and early next week.”

The highest temperatures are expected in parts of central, east and southeast England, peaking on Monday over 30°C widely and possibly 33-34°C in some places. This will be accompanied by some high night-time temperatures and humidity, especially on Sunday night in southern and western areas.

Elsewhere, while Sunday will be a fine day for much of Scotland and Northern Ireland, here temperatures
