It will become drier and clearer from the west overnight, with temperatures dropping as low as 10C in some areas. The forecaster continued:

"Much of Saturday night will be dry but cloud will increase from the Atlantic with rain developing in Western parts towards morning and it will become breezy there with freshening southerly winds. Lowest temperatures of 11C to 14C degrees. "Sunday will be a breezy day with outbreaks of rain, possibly turning heavy in the west and north with the best chance of dry and bright weather in the east. "Highest temperatures of 18C to 22C degrees in fresh southerly winds. A humid night will follow with temperatures not lower than 15C to 17C degrees.
