National Outlook
It'll be mild this weekend with mixed weather. It'll be mainly dry on Saturday, and while there'll be a little rain or some showers on Sunday, there'll be good dry spells too. While there's still some uncertainty, it looks like it'll become mainly dry from early next week for a few days at least and it's likely to become milder.
Friday night: Any lingering rain in the east will clear early in the night, so it'll become mostly dry with clear spells and just a few isolated showers, these mainly in the west. Some mist and fog will form in just light southwest or variable breezes. Lowest temperatures of 4 to 9 degrees.
Saturday: The mist and fog will generally clear on Saturday morning to leave a mainly dry, bright day with good spells of sunshine. There'll just be a few isolated showers and a slight chance that a little bit of sea fog may encroach onto coastal parts of the east and southeast at times. It'll become cloudier in the west in the evening. Mild with highest temperatures of 14 to 17 degrees in light to moderate south to southwest winds, freshening along the west coast through the afternoon.
Saturday night: Cloud will increase from the west, with some rain and drizzle moving in from the west and spreading further eastwards overnight. Lowest temperatures of 8 to 11 degrees in mostly moderate southerly winds, fresher along the west coast.
Sunday: There's some uncertainty in the details for Sunday and while it's likely to be cloudy for a time, with a little rain and some showers, it looks like it'll become drier and brighter through the day, with some sunny spells developing, the best of these in the east. It'll be a breezy day with highest temperatures of 14 to 17 degrees in moderate to fresh and occasionally gusty south to southwest winds.
Sunday night: is likely to bring a good lot of cloud and while it'll be dry in many areas, a little light patchy rain and drizzle is likely, mainly in the west and northwest. Lowest temperatures of 9 to 11 degrees with southerly winds decreasing mostly moderate.
Monday: Apart from the chance of a little patchy light rain and drizzle early in the day in the northwest, Monday promises to be mainly dry with high pressure starting to dominate. While it'll be mostly cloudy for a time, some hazy spells of sunshine will develop. Highest temperatures of 14 to 18 degrees in mostly moderate south to southeast winds.
While there's still some uncertainty and while some rain and drizzle may come close to western coastal parts, it looks like the following few days will be mostly dry with spells of warm sunshine.
