Tue 6 Jan South West England

Cold northerly winds dominant across the UK in the first week of January bring wintry showers (often of snow) to many coastlines (and areas just inland of these) that are exposed to onshore winds. Into the new week more coherent bands of precipitation and thicker cloud will attempt to move in from the west, with a risk of further snow on the leading edge of these turning to rain. Confidence is low in the rate of this return to a more mild Atlantic flow, with a risk of further artic airflows following fronts to resume wintry showers, especially across northern areas of the UK. Temperatures recovering to just below average for most, though further north more likely to return cold at times.
