New weather maps from WXCHARTS, using MetDek data, show lows of 3C hitting parts of Scotland within hours. On Friday July 31, temperatures will plunge from the mid-20sC currently being enjoyed to highs of 14C along England's east coast.
Five Scottish counties below 5C
A total of five counties will drop below 5C by 6am on Friday, all in Scotland: Perthshire, Inverness-shire, Moray, Banffshire, and Aberdeenshire. England is expected to be milder, with many areas in the East, South East, and South West reaching double digits.
Met Office forecast
The Met Office forecast for Friday reads: "Mostly dry in the south and southeast on Friday with some warm spells of sunshine. Cooler, with a breeze towards the north and northwest, and a scattering of showers." The agency added that temperatures are expected to be much closer to average across most of the UK, and slightly below average for northern Scotland.
Deputy chief forecaster Mark Sidaway said: "The forecast is showing potential for more rain than much of the UK has experienced over the last few weeks. However, it looks as though amounts of rain for many will be fairly modest, and won't balance out the shortfall that we have recorded this summer. It’s still possible that some areas of the south will miss out and see little or no rainfall."
