Warm and muggy again

Monday saw us still under the influence of the warm and most air from the Atlantic that, with late sunshine amounting to 1.2 hours, raised the maximum to 23.2C. This was 2.6C above the 34-year average and almost identical to the Sunday maximum.

There were occasional very brief bouts of drizzle that were not measurable, which is referred to as a ‘trace’ in the records.

The thick cloud overnight acted as a duvet in that it restricted the radiation of warmth from the ground into the atmosphere resulting in a minimum of 16.0C, which was 4.5C above the average, at 02.45 early this morning that rose fractionally to 16.8C at 08.00 when readings were taken.

Tuesday arrived with the thick cloud that at 08.00 brought thicker cloud and another brief interlude of drizzle.

Update at 14.50: slack pressure gradient has meant many brief periods today when the anemometer was becalmed and a maximum gust of 9mph. Humidity is again very high, currently at 74%.

Update at 16.40: peak temperature of 22.5C, being 1.5C above average, reached at 16.22 thanks to late afternoon sunshine.
