Portrush, Northern Ireland, United Kingdom Severe Weather Alertstar_ratehome

Clear spells on Friday evening and overnight will allow temperatures to quickly fall below freezing, leading to the development of icy stretches, especially on untreated surfaces. A scattering of wintry showers are also expected, these falling as snow over hills above 200 m, where further small accumulations of 1 to 3 cm are possible in a few places.

A band of snow will move across the warning area through Sunday morning. Across northern England this will mostly be confined to ground above 200 metres elevation, but across Scotland this could fall to low levels during the morning, before becoming increasingly confined to higher ground through the afternoon.

Whilst not all areas may see accumulating snow at low levels, 2 to 5cm is likely, perhaps locally 10 cm. Above 200 metres elevation 10 to 20 cm is possible, perhaps locally up to 30 cm on hills exposed to the strong southerly winds, and over the highest parts of Scotland. Strong winds will lead to some drifting of the snow, and widely icy conditions are likely.

Amounts of snow will depend quite heavily on both elevation and the intensity of precipitation, and as the band pushes east through the afternoon, it will begin to transition to an awkward mix of rain, sleet and snow. Therefore there is likely to be a lot of variation, even over relatively short distances.
