A change from mild and wet weather to cold wintry conditions later this week.
The next 24 hours: Showers of rain, hail and sleet expected this afternoon and evening. Some wet snow possible above 300m later this afternoon and into the evening. Snow levels falling quite quickly this evening though. A risk of some brief wet snow in any heavier showers down to low levels from 2100 to 0600 but only trace accumulations of 0-1cm possible below 200m. Greater accumulations expected at high levels with 1-3cm between 200-300m, 3-5cm between 300-400m and 5-10cm above 400m in these showers. A low risk that locally there could be up to 20cm above 400m if showers are persistently heavy. Snow line will gradually rise through the morning but snow still impacting routes above 400m by 1200 Monday.
