A fine Spring day on Sunday, with plenty of sunshine, light winds and a maximum temperature of 14.2 (1422z). The air was dry, though, with dew points as low as -2, so it didn't feel quite as warm as the thermometer suggested.. Clear skies continued into the evening, allowing a slight air frost. Minimum temperature was -0.6 (0303z). A stratocumulus sheet spread across from the northwest after 0330z, with temperatures rising as a result. Excellent visibility throughout Sunday and overnight into today. Currently cloudy and cold with a skim of ice on puddles, but no hoar frost.

The stratocumulus broke to small amounts for a while allowing some sunshine, but a layer of lower stratocumulus spread in from the west around 0800z and it is now cloudy - but with sufficient breaks to see the higher layer still. Visibility down on earlier, but still very good.
