High pressure will likely sit to the northeast of the UK during this period. Consequently, winds across many areas are likely to come from an easterly quadrant, exacerbating the cold feel, with temperatures often below average. At first, there is the chance of more widespread precipitation, most likely mainly rain, across southernmost areas, before this clears away. Thereafter, there is a risk of some sleet or snow showers feeding in on the east to southeasterly wind, though many places may remain dry. Also a small chance of Atlantic fronts making inroads from the west, especially later in this period, which could also bring the possibility of at least transient snow. Overnight frost is likely to feature during this period, particularly where skies are clear.

Weather patterns in the UK are most likely to be slowly evolving during this period. It is most likely that high pressure to the east or northeast of the UK will dominate at first in some form or another, but with time this may decline, allowing an erratic transition to rather more unsettled and possibly less cold conditions. During this transition there is the possibility of more prolonged rain or snow developing, at least for a time, but confidence in these details is currently very low.
