UK long range weather forecast

The period will start unsettled across all parts of the UK, with areas of heavy rain and showers, locally of soft hail, sleet and snow likely, and possibly more widespread snow over some hills and mountains. Often windy, especially around coasts, but in quieter interludes overnight there will remain the potential for some patchy frost, and isolated mist and freezing fog. Temperatures are expected to be a below average overall. Later in this period, it could turn drier and more settled with a chance of high pressure moving in from the north, bringing brisk easterly winds. Again, where winds fall lighter, overnight frost and patchy fog is likely, this perhaps most likely in the north. Near, to slightly below, average temperatures are most likely.


Despite some mixed signals, the general trend suggests typical early winter weather with periods of persistent rain and showery interludes. Cloudy and blustery conditions are still likely in the east at first. Overall, the best of the driest and brightest weather is in the south and east. Frost and fog patches are likely during any settled spells, and any wintry precipitation is likely in colder and more unsettled spells over high ground of the north and northwest. Conditions in the southwest are likely to turn more settled through the month. There is a risk of gales, with the strongest winds being seen to the north and northwest.
