Anticyclone brings dry but not warm weather

A maximum of 13.6C on Thursday was again below average at -0.5C as the high pressure to the west of the UK continued to feed cold air down from the north arriving on a brisk westerly gusting to 20mph at its strongest. The cloud overnight acted as a duvet limiting the loss of warmth to the atmosphere thus producing a minimum of 8.1C, which was 4.4C above my 40-year average.

Thursday brought the strongest sunshine in strength (w/m2) since 15th August and the highest UV since 3rd September registering 5.6, which was well into the ‘High’ category. It was also the third continuous dry day. The monthly rainfall total is 41.4mm being 73% of my 40-year average.

Friday revealed weak intermittent sunshine after dawn but predominantly cloudy.The wind is still cool and brisk with a more northerly component than on Thursday, so another cool and probably mainly cloudy day. The wind will slowly veer into the northeast as the day progresses, a direction not occurring since March. The cold air is originating north of Iceland and is streaming down the North Sea.

The anticyclone is still centred to the west of the UK although edging closer and likely to dominate our weather for the next few days.
