Sat 15 Nov London and South East England

The start of this period is likely to be unsettled and mild for most, with slow-moving bands of rain which could be quite heavy and prolonged in some areas. With time, the more unsettled conditions should gradually clear to the south, allowing a colder and more showery northerly flow of sorts to become established. In this setup, showers may be wintry over high ground, and perhaps occasionally to low levels in the far north, with also a greater risk of overnight frost. However, the timing of this transition is rather uncertain, and it could remain milder and wetter into the beginning of the following week, especially in the south. A general downward trend in temperature is most likely through this period, to below average in many areas beyond mid-November.
