Mon 22 Dec South West England

Unsettled conditions are likely to continue at first, with low pressure probably centred somewhere to the southwest of the UK, whilst high pressure becomes established to the northeast. This means a broadly easterly flow will become increasingly dominant through next week, whilst periods of rain or showers become increasingly confined to southern or southwestern parts. With time, high pressure is signaled to become more dominant with more in the way of dry, settled weather anticipated though there could be some isolated showers to eastern parts, that could perhaps be wintry at times. Temperatures will lower compared to recent weeks, closer to or perhaps a little below average for many. Overnight frost and fog or freezing fog could become more prevalent, though any particularly cold conditions look unlikely at this stage.
