21:00 on Thursday until 10:00 on Friday:
Wintry showers later on Thursday and overnight into Friday will lead to some ice, 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 100-200 m and more than 6 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.
Chief Forecaster's assessment:
"A cold northwesterly airstream will 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."
