M56: National Highways warns of disruption as arctic air brings snow

National Highways has issued an amber severe weather alert for snow across parts of the North West, including the M56 in Manchester, from 7 pm on Monday, November 18, to 10 am on Tuesday.

Forecasters predict up to 5 cm of snow, with disruptions likely on the Strategic Road Network (SRN).

The alert, distinct from Met Office warnings, highlights specific risks to drivers.

Darren Clark, Severe Weather Resilience Manager at National Highways, urged motorists to exercise caution:

“Gritters will be out treating our roads around the clock when ice or snow is forecast, but it is still important to drive to the conditions.

“Keep your distance and reduce your speed, because even in conditions that seem normal, and where the snow is not settling, it can be slippery if ice patches have formed, or where fresh grit has not been worked into the carriageway. Drivers should plan their journeys, monitor weather reports and pack a snow kit of blankets, food, water and a shovel.”

Snow and ice warnings remain in place for northern England, Scotland, North Wales—including Flintshire—and the north Midlands. Higher areas may see up to 20 cm of snow, while icy patches on untreated roads are expected as rain and sleet clear on Tuesday.

Dan Suri, Chief Meteorologist at the Met Office, warned of potential rush-hour disruption:

“An area of low pressure will bring disruptive snow to some areas between Monday night and Tuesday morning, likely coinciding with rush hour.”

Wintry Conditions to Persist Through the Week

As the weather front moves south on Tuesday, cold northerly winds will spread across the UK, leaving daytime temperatures in the low single figures for most regions. Sub-zero wind chills are expected, although the south may experience slightly milder conditions.

Despite the cold, many areas away from coastal regions will see sunshine during the week.

A shift to milder, wetter, and possibly windier conditions is forecast for the weekend as temperatures begin to rise, bringing relief from the Arctic airmass dominating the early part of the week.

Motorists and residents are advised to stay updated on weather alerts and prepare for wintry conditions, particularly in higher regions.
