Cold or very cold conditions are likely to affect most if not all parts of the UK early in this period, with wintry showers affecting in particular northern parts and exposed coastal districts. Overnight frost will likely be widespread and occasionally strong winds will result in significant wind chill. However, there may be more organised areas of rain and snow, accompanied by strong winds, which run across some parts. This could lead to some disruptive weather at times, especially at the start of this period. Briefly milder conditions may accompany these in the south. There is a hint that it may become less cold late in the period, but still likely remain mostly unsettled with further spells of rain and snow.

Signals vary in prevailing weather patterns through this period. In general, there looks like a trend towards drier and more settled conditions, with high pressure potentially being the more dominant influence over the UK. However. there is a chance of more changeable weather patterns at times, which would see Atlantic weather systems periodically move across the country. These will bring some wetter and windier interludes with a risk of some snow, especially for hills in the north. Temperatures trending closer to average, especially in the south.
