Early morning commuters warned of potential icy delays as Met Office issues overnight weather warning.

Overnight snow and rain mixed with a cool northernly breeze are expected to cause problems for early morning travellers tomorrow (November 19).

The Met Office has now issued a yellow weather warning for ice across much of the West Yorkshire and Greater Manchester area, spreading all the way across Wales as temperatures continue to drop.

The national forecast agency has said that the temperatures will dip to 1 °C in Sheffield overnight (November 18) following increasingly strong northernly winds.

This brisk winterly breeze is expected to bring rain and snow in hilly areas, though skies will clear by tomorrow morning (November 19).

However, while there’s only a 10 per cent chance of rain on Wednesday, the overnight downpour and dropping temperatures have increased the risk of ice, particularly across the west of Sheffield.

Temperatures will continue to drop, reaching -1 °C in the early hours of Thursday (November 20) morning.

In a statement, the Met Office explains: “Outbreaks of rain will spread southwards on Tuesday night into Wednesday morning, potentially falling as snow on hills for a time, before clearing to the south.

“As skies clear later, allowing temperatures to fall close to or below freezing, this will bring the risk of icy patches on untreated surfaces.

“Some temporary slushy snow deposits will be possible where snow persists for long enough, especially on grassy surfaces, but any significant accumulations will be largely restricted to communities and transport routes above about 300 m elevation.”

It means that those travelling across hillier areas, especially spreading into the Peak District, should prepare for potential delays in their early commutes.
