There is much uncertainty about the weather during the first couple of days, but we are currently expecting various fronts to make slow progress eastwards across the UK, bringing rain, sleet and possibly also some significant snow in places. The wettest conditions will be in the west and there is a fair chance that eastern areas will remain cold and dry until the weekend. Then from the weekend onwards the most likely scenario is for milder and unsettled conditions with showers or longer spells of rain to spread across all areas, with the heaviest rain likely to occur in the west and southwest. Although it should be generally mild there could be brief colder spells between the bands of rain.
As we move from January into February northern areas are likely to see an unsettled period, with outbreaks of rain, strong winds, and some hill snow mixed with brighter, drier periods. Southern parts in contrast should see drier and more settled conditions, although rain cannot be ruled out. Overall temperatures are expected to be around normal, but possibly slightly below average in the south and east.
