A chilly but bright start in the south with any early fog soon clearing leaving plenty of sunny spells. A cloudier day in the north with patchy rain or drizzle. Maximum temperature 12 °C.

Outlook for Saturday to Monday:

Often cloudy on Saturday with rain moving through from the north. Unsettled on Sunday with heavy rain or showers and stronger winds. Sunshine and showers on Monday and turning colder.

Frequent wintry showers are expected, mainly in the north and along eastern and western coasts where exposed to the strong north to northwesterly flow. Snow is likely to fall to low levels, especially in the north. Many inland areas may be largely dry with lengthy sunny spells, especially where sheltered from the flow. However, there is a risk of some more organised areas of rain and hill snow running east across more southern parts. The chance of any widespread or disruptive snowfall affecting more populated areas at this stage remains low though. Cold everywhere with overnight frost, and the strong winds will result in significant wind chill. There is a hint that it may become less cold later in the period, with more of a westerly flow becoming established.

Signals vary in prevailing weather patterns through this period but likely mainly unsettled and rather cold for the start of the period. There is a chance of more mobile weather patterns which would see Atlantic systems periodically move across the country. These will bring some wetter and windier interludes with a risk of some snow, especially for hills of the north. A trend toward less mobile weather or more settled conditions is favoured into December, although some wetter and windier interludes remain likely at times. Temperatures also trending closer to average, especially in the south.
