A vast storm system stretching an estimated seven hundred and sixty-nine miles is forecast to sweep across the United Kingdom in mid-November, bringing a mix of snow, heavy rain and strong winds to large parts of England, Wales and Scotland.

Meteorological maps show cold blue and purple shades over the UK as temperatures fall while a band of precipitation advances from the west.

According to long-range forecasts issued by the national meteorological service, snow is likely in northern regions such as Perth and Kinross, Stirling and the Scottish Highlands, with up to one centimetre of snow per hour in some locations.

Meanwhile, western parts of Wales and the Highlands may receive rain at rates of up to five millimetres per hour and three to four millimetres residual spreading across southwestern England, including Devon and Cornwall.

Temperature profiles will plunge overnight.

In the Scottish Highlands, readings could near zero °C, with Aberdeen and Inverness dropping to just one °C. Northern England may see daytime highs between three and four °C, while Wales may reach around five °C and the South-East, including London and Surrey, could stay milder at seven to nine °C with little rain.

The national meteorological service warns that all areas should expect some heavy rain, though western regions are most likely to be affected.

Strong winds—potentially gales along exposed coastal sections—are also expected.

The forecaster advises that lowest travel-impact delays are likely in eastern and more sheltered zones, but conditions may worsen quickly in the west.

Residents and transport authorities are already being urged to prepare.

The combination of snow, heavy showers and wind may bring disruption to roads, railways and ferry routes—especially in hilly or exposed terrain.

While the forecast is several days out and subject to change, the broad consensus is that the UK will face one of its more significant early-winter weather events of the season.
