Predominantly cyclonic patterns are expected to dominate the UK. The early part of this period could see colder conditions becoming established more widely for a time, bringing with it the likelihood of some snow, primarily to the north and northeast. However this should offer a few days respite from the wet weather across the south. By the end of this period, the track of Atlantic depressions may shift a little further north than during the last few weeks. This will maintain broadly unsettled weather, with further spells of rain and perhaps strong winds at times. Many parts may become somewhat milder, given more of a westerly influence, though there remains the chance that colder conditions could linger towards the northeast.

Broadly changeable conditions are expected across the UK during this period. Low pressure systems will probably dominate, meaning showers or longer spells of rain, heavy at times, for much of the UK, and still the chance of some hill snow in the north. Some drier interludes are likely, though it must be said, flooding impacts remain possible given recent very wet weather. Windy conditions look probable from time to time. Temperatures probably close to or a little above average overall, with a reduced chance, compared to earlier thinking, of a late season prolonged cold spell.
