This period is likely to start changeable and often unsettled but relatively mild, with rain or showers for most places. There is potential for a deep area of low pressure to develop to the west or northwest of the UK early in this period, bringing a spell of very strong winds and heavy rain, especially to parts of the west and north. Towards the latter part of October, there are signs that whilst northwestern areas may continue to feel the influence of areas of low pressure, further south pressure is expected to build, bringing more in the way of fine, settled conditions. With this comes an increasing chance of overnight frost and fog, with the latter perhaps persisting well into the day in some areas.

Potentially some wet and windy weather at first, especially in the northwest, but a trend towards more settled conditions is most favoured for late October as high pressure becomes increasingly dominant. This would bring the potential for frost and fog at night, and possibly large variations between daytime and overnight temperatures. Into early November, high pressure may become more centred to the northwest of the UK, resulting in a gradual trend towards more unsettled conditions, particularly across southern regions.
