Weather charts produced by NetWeather.TV shows a band of wintery showers circulating in the North Atlantic as temperatures across the UK plummet. The weather model shows a deep blue area of low pressure building in the Nordic Island of Iceland just north of the UK.
The cold weather system, bringing wintry weather to Iceland, is set to bring a spell of heavy rain across large parts of Britain from tomorrow evening and has already triggered a weather warning for parts of Scotland.
In a post on Twitter, NetWeather.TV said: “A waving front out west will eventually move inland as an active cold front in the evening. Heavy and persistent rain #Highlands.
“Disruption to travel and localised flooding possible. Freshening southerly winds, coastal gales. #Floodaware.
“Lots of rain for the rest of this week. 1. Out west today, bringing wintry weather to Iceland tonight. 2. Weds warned low and 3. Thurs/Fri – more rain for NI, Scotland later Wales, northwest and southwest England.”
NetWeather.TV forecaster Nick Finnis added a “strong jet stream moves in off the Atlantic” from Wednesday bringing a spell of wet weather and strong winds.
Overnight temperatures will fall during the early hours of Wednesday morning with lows of 6C in Scotland, 5C north and 7C in London.
By Wednesday morning, Scotland, northwestern parts of England and Northern Ireland are set to see the worst of the wet weather before strong gales push the weather front eastwards.
Mr Finnis said: “After recent fairly calm weather, a change on Wednesday, as strong southerly or southwesterly winds develop ahead of a deepening low pressure system moving northeast towards western Scotland and associated squally active cold front moving east.
“The low and its cold front will bring wet and windy conditions eastwards across Scotland, northwest England, Northern Ireland through the morning and lingering into the afternoon.
“Outbreaks of heavy squally rain then pushing in across Wales, southwest England and the Midlands during the afternoon.”
The threat of heavy showers on Wednesday has triggered a yellow weather warning for the west of Scotland.
The Met Office has put a warning in place from 2am on Wednesday until midnight on Thursday.

“The weekend continuing the unsettled theme, with low pressure in charge, bringing windy conditions, spells of rain or showers.
