Cold front means drop of 6C

The effects of the cold front were felt yesterday when the thermometer struggled to reach 4.9C just after midday. The occasional showers, especially in the early evening, produced another 1.3mm of rainfall. After falling over four consecutive days the barometric pressure reached a low of 991.9mb early yesterday but the last twenty-four hours have seen a recovery to 1002.6mb this morning.
Overnight the clearing skies meant that the thermometer dropped further with a light frost giving a minimum air temperature of 0.2C at 08.00. The recent rainfall and high humidity produced much frozen moisture on surfaces that gave the impression of a much harder frost. The sun began to rise above the horizon at 07.50, in an almost clear blue sky, which will shortly begin to lift the temperature.
