A wall of rain is set to strike Britain this week in the aftermath of Storm Debby which triggered flash flooding across mid-Atlantic and northeastern US states.
Forecasters say temperatures could soar to 34C on Monday with "rising humidity" ahead of the heavy downpour on Thursday.
Britons are set to bask in the short-lived sunshine with highs predicted to reach 34C in London, 26C in Manchester, 22C in Glasgow and 21C in Belfast.
According to weather experts, the spike in warmth is partly due to Storm Debby - which saw parts of the US inundated with rain.
