Snow & Ice

[Updated 4:45pm] Showers will fall as rain/sleet to low-levels and sleet for high ground will be replaced by a larger area of showery rain this evening and overnight tonight. This rain falling as sleet and snow for high ground with any snow confined to above 800 FT.

Towards the end of the overnight period (from around 5am) colder air allows the snow level to lower, but at the same time the precipitation starts to become confined to the south of the island early on Friday morning but will fall as a mixture of rain, sleet or hail to low-levels and as snow/hail above 300 FT. Elsewhere under increasingly clearer skies, there is a risk of ice forming on wet surfaces until mid-late morning, especially anywhere sheltered from the northerly winds.

Slight accumulations of snow possible above 800 FT overnight and then Friday morning accumulations are also possible above 300 FT in areas affected by the wintry showers – this most likely in the south of the island. Any accumulations of hail to low-levels will be short-lived but may cause some isolated icy patches.
