With a maximum of 5.4C on Friday it was the warmest day since the 14th but still 1.7C below my 40-year average. This was thanks to the change in wind direction to southwest after the northerly direction of previous days. It was the 13th consecutive dry day after the previous wet months so a welcome drying oil.
Initially the thermometer produced an air frost late evening with a minimum of -0.9C at 22.10 but then did an about turn and began to rise again to 2.7C at -08.00 on Saturday thanks to the wind backing further into the south or south southwest.
The high pressure is now well away over the Continent hence the change in wind direction as a deep depression, named Storm Isha, slowly approaches the UK. The pressure reading at 08.00 was 1024.5mb, the highest for a week so a relatively quiet day before all changes tomorrow.
