CHRISTMAS EVE: Overcast with patchy drizzle, dying out for a time in the late morning or early afternoon with some short sunny breaks possible.

OVERNIGHT: Wet and windy with some heavy falls of rain expected later in the night before dawn. Mild with lows of 9c or 10c or so, however – colder air behind the rain will begin to dig in and temperatures will drop to around 6c at dawn.

A clearance from the west will slowly extend eastwards. OVERNIGHT: Any rain, sleet and snow will clear and skies will become generally clear too, though a wintry shower or two cannot be ruled out.
