13:20 on Friday until 10:00 on Saturday
Wintry showers, continuing during Friday and overnight, will lead to the possibility of ice forming as temperatures fall this evening and overnight. This will occur primarily on untreated surfaces but perhaps also where grit is washed off by frequent showers. Additionally, 1-3 cm of snow may accumulate on hills above around 150 m and more than 5 cm above 400 m. Some of the heaviest showers could produce slushy conditions even at low levels. Please be aware of possible tricky travel conditions. The warning has been updated to adjust the start time forward, and include more of the Yorkshire Pennine area.
Chief Forecaster's assessment
A cold northwesterly airstream will continue to bring heavy showers or rain, sleet, snow and hail through this period. Clear spells in between will allow temperatures to fall close to or below freezing - hence the likelihood of some ice.
