UK snow forecast may reach major cities including London

The GFS model forecasts snow across much of the UK around January 23–25, with maps showing snow from southern England to northern Scotland and modest accumulations expected; BBC Weather's long-range outlook says there is little sign of a lasting cold regime but uncertainty increases.

The GFS weather model indicates snow falling across large parts of the UK around January 23–25. Maps referenced in the report show snow on the ground from the southern coast of England up to northern Scotland, covering roughly 600 miles and including several major cities. Forecasted accumulations are smaller than in the 2018 "Beast from the East," with the data suggesting up to eight inches in parts of Scotland and lower amounts further south. BBC Weather's longer-range outlook notes only a limited chance of a lasting cold spell while also saying uncertainty increases further ahead. Key details: - The GFS model shows continued snowfall through January 23 and 24, with coverage on maps for January 24 and 25. - Snow on the maps is shown from southern England to the far north of Scotland, spanning roughly 600 miles and including London, Bristol, Cardiff, Birmingham, Nottingham, Norwich, Manchester, Newcastle, Edinburgh, Glasgow, Dundee and Aberdeen. - Modelled accumulations cited in the report are about eight inches in parts of Scotland, around two inches in northern England, and roughly one inch elsewhere. - BBC Weather's January 19–25 forecast describes a low chance of meaningful widespread snowfall but possible wintry showers, mainly in northern regions. - BBC Weather's January 26–February 8 outlook says mild west to south-westerly winds and Atlantic systems are likely to dominate, with chiller interludes short-lived; it also notes uncertainty and a possible but unfavoured scenario of high pressure at higher latitudes bringing colder flows. Summary: Snow is forecast across a broad swathe of the UK in late January, with maps and model runs showing coverage from the south coast to northern Scotland and generally modest accumulations compared with past extreme events. BBC Weather's longer-range guidance suggests limited signs of a sustained cold regime, while also noting increased uncertainty further ahead. Undetermined at this time.
