Morden Hall Park (Greater London) weather

Headline:

Remaining mild through to the weekend.

Today:

A continuation of the recent cloudy and mild weather is forecast for Boxing Day. Although perhaps a greater chance of early morning fog patches which will be slow to clear, and for more persistent overcast skies later. Maximum temperature 10 °C.

Tonight:

Cloud tending to thicken across the region with further patchy light rain or drizzle. Quite misty generally perhaps with fog forming later in the night further east. Minimum temperature 4 °C.

Friday:

Another cloudy mild day with light winds and patchy fog which may be slow to clear. Some rain or drizzle, especially further west. Maximum temperature 8 °C.

Outlook for Saturday to Monday:

Cloudy on Saturday though most parts staying dry. Sunday and Monday should be a brighter days, breezy, perhaps with the odd shower and temperatures nearer average for late December.

Fronts or low-pressure areas are increasingly likely to move south/east across much of the country, bringing an increased threat of heavy rain and perhaps strong winds. As colder air from the north progresses southwards, the risk of sleet and snow increases, especially in northern areas, but this will depend each day on where the thermal boundary lies. Temperatures will start around average but will become a little below average for most, especially in the north, though milder interludes are still possible in the south. While there is moderate to high confidence in this trend, confidence is low for the exact positioning of any systems, which will be crucial in determining which areas see rain or snow.

Confidence in this period is fairly low, but continuing from the previous period, there remains a chance of rather unsettled and cool conditions continuing at first, with the wettest conditions perhaps focussed more over the south (still with a risk of snow on the northern edge), with sleet and snow showers further north. Then, through the rest of January, something more climatological could return with the wettest and coolest conditions further north, and with higher pressure further south, it is more likely to be drier, and at times milder here than elsewhere.
