Foggy start to dull and largely dry day ahead

A status yellow fog warning will remain in place until 11am this morning (Monday).

Met Éireann is warning: 'Fog patches will be dense in parts giving reduced visibilities and poor driving conditions.'

Today will be a rather dull day with mist and fog gradually clearing through the morning and just a few brighter spells in places. Whilst most areas will remain dry, a little patchy drizzle is possible. Highest temperatures of 5 to 9 degrees Celsius, in a light to moderate east to southeast breeze.

Cloudy and mostly dry tonight with some mist and fog in places. A few spots of drizzle possible too. A touch of frost forming locally under any clear spells. Lowest temperatures generally of 2 to 5 degrees, locally colder under any clear spells, in light or moderate southeasterly winds.

Continuing mostly dry and cloudy for tomorrow, Tuesday with a few brighter spells locally. Risk of a few spots of drizzle too. Highest temperatures of 5 to 8 degrees in mostly moderate southeasterly winds, fresher near Atlantic coasts.

Staying mostly cloudy on Tuesday night, with rain extending into the west and southwest overnight accompanied by strengthening southeast winds. Lowest temperatures of 3 to 6 degrees, coldest over Ulster.

The rain will spread countrywide on Wednesday morning. Drier conditions will follow for a time in the afternoon but with more rain likely again in the evening and early night. It will be a bit milder on Wednesday with highest temperatures of 9 to 12 degrees in moderate to fresh south to southeast breezes.

Any lingering overnight rain in the northeast will clear on Thursday morning to give drier conditions apart from a little drizzle. Some brighter spells will develop and it will be quite mild with highest temperatures of 10 to 12 degrees in a light southerly breeze. Some rain may return to the southwest later.

Friday, Christmas eve, will bring rain at times in light to moderate east to southeast breezes. A bit colder with highs of 7 to 9 degrees.

At the moment, Christmas day looks like bringing some further rain at times but dry periods too. Highest temperatures around 5 to 9 degrees (coldest over north Ulster with some sleet possible on hills).

The further outlook period will probably gradually turn colder.
