Much of this period looks like being largely dominated by high pressure, especially towards the south or southeast of the UK. This will mean many places seeing plenty of dry weather with variable cloud amounts and some sunshine, the best of this towards the south or southeast, but perhaps with some fog overnight. However, frontal systems are still likely to affect the north and west of the UK at times though, maybe also briefly affecting other parts, bringing some rain and strong winds, and perhaps a little snow to the high ground in the north. Temperatures will be near or above normal, although patchy overnight frost is still likely at times.

After a potentially mainly dry and settled start to this period, more particularly towards the south or southeast, changeable conditions look likely to resume by mid-March, with Atlantic frontal systems spreading across all of the UK at times. These will bring spells of rain and perhaps strong winds, with the wettest conditions likely to be in the northwest, whilst the southeast will likely be driest. Some hill snow is possible in the north too. Some drier, clearer interludes are likely between frontal systems, but these are likely to be short-lived. Temperatures are likely to be near or slightly above normal overall.
