National Outlook

Overview: A little rain and drizzle on Sunday as a weak weather front sinks southeastwards, but overall plenty of dry weather for the rest of the weekend and the start of next week. It'll turn more unsettled and mixed though from Monday night and for the rest of the week with some rain and showers on the way. Colder too, with some of the showers turning wintry through midweek and it'll be windy at times.

Saturday night: Dry for a time with clear spells and with some patches of mist and fog forming, mainly further south. Cloud will increase from the northwest overnight with a little light rain and drizzle starting to move south-eastwards. Lowest temperatures of 1 to 8 degrees, coldest across the south and southeast, with just light variable breezes initially, becoming mostly light to moderate southwesterly and a little fresher in northwestern coastal parts.

Sunday: Generally cloudy for a time with a little rain and drizzle moving southeastwards. However, a clearance to mostly dry weather with some bright or sunny spells will extend from the northwest to most parts through the morning and afternoon. Highest temperatures of 10 to 14 degrees in light to moderate southwesterly winds, veering northwesterly.

Sunday night: Sunday night will be dry with a mix of cloud and clear spells. Lowest temperatures of 0 to 5 degrees, with a touch of frost possible in places, with just light variable breezes.

Monday: Monday will hold mostly dry with some hazy spells of sunshine, though it'll become increasingly cloudy with some light rain and drizzle moving into northwestern parts later. Highest temperatures of 10 to 13 degrees with southwest winds increasing mostly moderate, fresher later in western and northwestern coastal parts.

Monday night: A breezy and cloudy night with outbreaks of rain moving south-eastwards to most parts. Lowest temperatures of 6 to 9 degrees in moderate to fresh and gusty southwest winds, stronger in western and northwestern coastal parts.

Tuesday: Cloudy for a time with further outbreaks of rain, heavy at times. The rain will gradually clear southeastwards through the day, with sunny spells and fairly widespread showers following, some of hail, with the chance of the off rumble of thunder. A blustery day with highest temperatures of 9 to 12 degrees in fresh and gusty southwesterly winds veering westerly, strong to near gale force and gusty in western coastal parts.

Tuesday night: Continuing rather windy and showery, some of the showers turning wintry and with a chance of thunder. Lowest temperatures of 0 to 4 degrees in fresh and gusty westerly winds, strong to near gale force in western coastal parts.

Wednesday: A windy and showery day and some of the showers will be heavy, with a chance of thunder. Some will be wintry too especially through the morning and again later. There'll be some sunny spells also. Highest temperatures of just 5 to 9 degrees, but feeling colder with the added wind chill from fresh to strong and gusty northwest winds, reaching near gale to gale force in western and northern coastal parts.

Thursday: Some frost and ice in parts to begin on Thursday. There'll still be scattered showers around, some wintry, but overall a good deal of dry weather with sunny spells. Breezy for a time, but the moderate to fresh northwest winds will gradually ease. Highest temperatures of just 5 to 8 degrees.

Further outlook: It looks like the weather will be mixed and changeable over the following few days, with some rain and drizzle from time to time as weather fronts break through, but some dry and sunnier spells too with high pressure moving closeby. It's likely to continue on the cool side with some frost.
