Under cloudy skies and a brisk westerly breeze the temperature on Monday eventually rose to a maximum of 5.7C at 13.46 being 1.4C below average. This below average temperature was not unexpected as the ground was still very cold from the Arctic air of previous days, there was no sunshine to lift the temperature and the cold air from around the Arctic was still in place. I deduce that the snow which was evident at daybreak on Tuesday fell in the early hours as the 5 minute radar showed a very red, angry display reaching our area at 06.10 and clearing at 06.35. The level snow depth was just 1cm that on melting amounted to 1.4mm of precipitation for the last twenty-four hours.
The thermometer fell to a minimum of 0.1C at 05.02 early Tuesday and lifted to 0.8C by 08.00 thanks to the cloud arriving at 06.10 that brought the snow minimising any further loss of warmth into the atmosphere in a previous relatively clear sky. The soil temperature at a depth of 5cm read 1.6C at 08.00.
The deep depression is very slowly easing eastwards towards Scandinavia but will still direct the cold air, originating from the north, on a westerly air stream. The barometric pressure has risen a significant 22mb over the last twenty-four hours with a reading of 997.9mb at 08.00.
We will still be on the cold north side of the Jet Stream until it is projected to move later in the weekend when it might get a little warmer
