The thick cloud on Saturday produced occasional light drizzle in the morning and just after 13.00 with a more sustained fall of light rain and drizzle starting at 15.00 that in total amounted to 2.6mm. This precipitation refreshed the plants but so little it did not sink far into the ground. In fact, just after 15.30 the sun came out as the back edge of the cloud eased away eastwards, that saw the late sunshine lift the temperature to a maximum of 21.9C at 17.27 being 0.8C below average, the first below average this month. The UV level of 3.9 placed it at the top end of the ‘Moderate’ level, the lowest for a month.
The cloud cover overnight meant a mild night with a low of 14.9C logged at 03.47 early Sunday.
The new day on Sunday revealed total cloud cover, which is due to a cold front passing over the UK, which will be closely followed by another around midday, so little expectation of much, if any, sunshine today. The barometric pressure has dropped to its lowest for a month with a reading of 1007.4mb at 08.00, down a significant 22mb since Friday.
The Azores High has now fully retreated to mid-Atlantic with the result our weather is influenced by the low pressure system to the north and northeast, in fact there are three of them, but none have a deep centre pressure. The realignment of the pressure systems will see the breeze come from the northwest today thus a cooler day combined with the cloud cover, and this wind direction will likely continue until Wednesday.
The Jet Stream forecast sees it begin to loop north of the UK on Tuesday that will result in the hot dry weather becoming increasingly prevalent from Wednesday.
