Mostly cloudy in Donegal today with limited bright spells and scattered showers

Mostly cloudy at first in Donegal today with just limited bright spells and scattered showers spreading from the west.

Brighter conditions will extend from the west through the afternoon with the showers becoming less frequent. Highest temperatures of 9 to 11 degrees, with moderate westerly winds.

Starting tonight with clear spells and mostly dry apart from a few isolated showers. However, cloud will build from the south in the second half of the night with outbreaks of rain and drizzle following. Lowest temperatures of 0 to 3 degrees, but increasing through the night with the arrival of the cloud, and with light southerly or variable winds.

Storm Dave will bring very windy and wet weather on Saturday. Southerly winds, veering southwesterly, will become very strong and gusty through the day. The strong onshore winds coinciding with high waves and high tides will pose a risk to wave overtopping and coastal flooding.

Outbreaks of rain and drizzle will move northwards in the morning, with some falls of sleet or snow possible on hills early on. Heavier and more persistent rain will spread eastwards across the province through the afternoon, with spot flooding possible. A clearance to scattered showers will follow later in the evening. Highest temperatures of 8 to 10 degrees.
