Sun 26 Oct London and South East England

An increasingly cold northerly flow to start this period, which will be showery around coastal areas but there will be some brighter spells inland. The showers could be wintry at times over the high ground in the far north. Into the following week conditions will likely turn increasingly changeable as a more westerly pattern develops. This will likely allow outbreaks of rain and some periods of stronger winds to spread into the UK from the Atlantic, but there will however be some drier interludes at times. The wettest weather will probably be in the north and west but much of the UK will see rain at times. Temperatures are expected to be close to or slightly below normal for the time of year.
