Thu 23 Jan London and South East England

A transition to a rather more changeable and at times unsettled weather pattern is likely to occur during the first few days of this period. Outbreaks of rain and freshening winds will probably make inroads from the southwest during Thursday ahead of conditions more widely becoming wetter and windier by next weekend. Whilst a milder, wetter and windier scenario is considered most likely, there remains a small chance that colder air from Europe may continue to feed into northern Britain, especially at first, increasing the chance of snowfall here. Towards the end of January, further periods of strong winds and heavy rain are likely to move in from the Atlantic. Whilst generally mild conditions look to close out the month, some large day to day changes in temperature are possible.
