Although Saturday morning was many overcast the afternoon sunshine boosted the temperature to a maximum of 24.1C late in the afternoon at 17.20, which was 2.7C above my 40-year average. The past night was again mild due to the cloud cover that had drifted inn on the breeze, now from the east or southeast, that collected moisture as it travelled across the North Sea. The low of 13.7C logged at 03.03 early Sunday was 1.9C above my average.
Sunday dawned dull with light winds but the shift in wind direction from southwest to east was notable. The thermometer had risen to 16.8C by 08.00. We must be optimistic that the sun will eventually burn away the moisture!
The temporary high pressure has been travelling east from North Wales since midnight and by midday is likely to be over the North Sea. This change in position is causing the wind to change direction to southeast. The barometric. pressure of 1021.9mb at 08.00, was the highest pressure this month and will allow the hot, dry air to pervade the country for a couple of days.
Update at 19.15: maximum of 29.3C logged at 12.45
