We are back to the warm, moist air that is being drawn up from a long way south, originating around North Africa and the Western Mediterranean. The thermometer slowly rose all day on Tuesday and Tuesday evening, from 5.7C on Tuesday at 08.00 to reach a peak of 11.7C on Wednesday morning at 08.00. Therefore the maximum was 3.8C above my 40-year average and the minimum overnight a very significant 10.1C above average. In fact it was a reverse in that it got warmer overnight, not cooler.
There were light showers during daylight hours on Tuesday and also triggered the automatic rain gauge at 06.15 on Wednesday amounting to 4.3mm. That took the monthly rainfall total to 63.7mm, just 2mm short of my 40-year average.
Wednesday dawned very slowly under thick, low cloud and very light drizzle. A temperature of 11.7C at 08.00 was the warmest start to a day since 24th December.
