A cold northerly flow will affect the UK initially, with widespread overnight frosts, below average temperatures and frequent wintry showers, these primarily in exposed northern, eastern and western coastal counties, but may feed farther inland in some places. Towards the end of the week and beyond, a transition to a milder but more unsettled regime is likely, as Atlantic frontal systems track eastwards across or near the UK. This will bring a chance of more widespread spells of rain or showers at times, perhaps with some occasional hill snow in the north, and the risk of some strong winds. Temperatures will tend to fluctuate from day to day, but overall will likely be close to average.

Whilst there is a lot of uncertainty as to the flavour of weather affecting the UK into December, there is a greater chance than normal of slower evolving weather patterns. This could bring rain or showers with hill snow also a possibility, mainly in the north. However, there are also likely to be periods of high pressure at times, bringing more in the way of dry weather, which would increase the chance of overnight fog and frost. Overall, temperatures close to average are most likely, but some colder spells are also possible, especially should any prolonged settled spells develop.
