“It is possible that there will be more widespread snowfall in the lowlands, but the likelihood of that happening for any given region is low at this point. What we do know is that the entire UK is likely to experience a multi-day period of cold and potentially disruptive weather next week.

“Warnings for winter hazards including snow and ice are possible, so it is important to keep up to date with the latest forecasts. »
