A mix of rain, sleet and snow will clear south over the country this evening and early tonight with a cold airmass following from the north.

The weather advisory is valid from 8:00p.m tonight to 9:00a.m on Tuesday.
Meanwhile, a Status Yellow Rainfall Warning for Co. Donegal remains in place until 3:00p.m today.
