The Polar Maritime Air that covered the country on Sunday, it originated near Iceland and Greenland, was very cool with the thermometer struggling to reach a maximum of 6.2C at 14.42 being 1.8C below the average. Not surprisingly, a cool night followed that saw the thermometer sink to 3.2C at 07.50 early Monday being 0.8C above the average. It was a dry day with just minimal UV light to trigger the sensor at 0.5.
Monday after dawn revealed a sky covered with thin cloud allowing minimal brightness, better than the recent gloomy days, but no sunshine. Thankfully the recent very strong winds have subsided so minimal wind chill, although feeling cold outside.
As the day progresses, the cloud will thicken as a warm weather front approaches and crosses the UK late Monday. This will result in the temperature rising during the late evening and overnight with some possible precipitation, but not white.
The barometric pressure has risen a significant 20mb over the past twenty-four hours as a very high pressure system mid-Atlantic begins to influence our weather allowing much milder weather to arrive on Tuesday for a few days over Christmas. This will allow a wedge of Tropical Maritime air to flood the country.
