Planning Outlook
A settled start to November as high pressure resides toward the north. Largely dry weather throughout the week ahead. Variable cloud will be drawn in from the North Sea on easterly winds, at times some light showers mainly for Pennine areas. Best chance for inversion conditions will be on higher tops in Scotland, emerging above cloud at times. Sunshine typically best toward western coasts. Temperatures mostly above freezing on high terrain, but some frost overnight in glens and some upland hollows. Quiet weather may continue into next weekend, then a trend toward more unsettled conditions into mid-month, possibly colder patterns too.
