Week ahead - December 16, 2017
Much milder
Rain mostly west

Issued: 1000hrs Saturday 16th December 2017
Duty forecaster: Garry Nicholson


Westerly winds dominate

A marked change to recent conditions, as mild southwesterly winds sweep across the country in the run up to Christmas. Very mild conditions are expected in the middle of the new week. Things may drop cooler from the north-west later in the week, but it does not look as cold as recent times. Occasional rain, most persistent in the west & north-west of the British Isles. Some fog and murk.
