After a cold start to December, conditions across many parts of the country have turned milder again but with the milder air came a return to unsettled conditions with a fair amount of rain falling in many regions keeping the number of flood alerts and warnings high.
There's good news and bad news this week. Starting with the bad news first and there is more rain or showers to come in the next few days as the unsettled theme continues, but we are not expecting rainfall amounts to be as high as they were last week in many places. The good news is that, at long last, there are signs of high pressure trying to become more influential as we head into the second half of the month meaning that some much needed drier weather is on the cards.
The change comes about later in the week as pressure builds from the southwest with a large anticyclone expected to be centred close to southern parts of the British Isles by next weekend. The exact position and orientation of this high will be crucial in determining the conditions that we see at the surface. If it remains to the south then milder south-westerly winds will feed around its northern flank bringing a lot of cloud and some rain towards the northwest where it will also be windy. However, if the high manages to edge further north then the chance of some clearer conditions increase but with this would come the risk of frost and fog by night.
