Turning more unsettled and significantly colder as we head into the weekend with rain or showers for most regions, The heaviest and most frequent spells of rain are most likely in the north where they are likely to turn wintry, especially to the hills of Scotland, but perhaps also to lower levels in the far north as colder air digs south. The chance of any widespread or disruptive snowfall affecting more populated areas at this stage however remains low. Less certainty for the south but even here there is a chance of some more organised rain, and potentially some hill snow. Often windy, with a chance of gales at times, especially in the north and east. Temperatures falling below average and feeling particularly cold in the strong winds.

Signals vary in prevailing weather patterns through this period but likely more unsettled and colder than during early November for the start of the period. There is a greater chance of more mobile weather patterns which would see Atlantic systems periodically move across the country. These bringing some wetter and windier interludes followed by drier periods and with the colder air in situ a greater 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.
