Through the weekend it is expected to be dry for many but often rather cloudy, with some light rain at times in the far north. Through the following week, high pressure is likely to be centred across or near to the UK, with dry and settled conditions for most but with the ongoing risk of frost and fog, the fog stubborn to clear in places. There is also an increasing risk of weather fronts across the northwest making erratic progress southeastwards. Behind these there could be brief, but rather cold periods, especially in the north and down the east coast where it will be windy. Temperatures are likely to be around or slightly above average in the north, though below average in the south, especially where fog persists.

High pressure is expected to be near or across the UK to start with, before gradually declining southwards further into February. This means that, especially at first, the generally settled conditions will prevail with bright or sunny spells. There is still the increased likelihood of frost and fog, the fog lingering all day in places. Later in February, it is likely to turn more changeable in the north, with outbreaks of rain and stronger winds. There is an increased chance of these pushing further south at times, though settled conditions are most likely to persist here. Temperatures are expected to be slightly above average overall, particularly in the north. Some colder interludes are still likely though, bringing a risk of occasional snow, most likely over northern hills.
