Another 1 hour of strong sunshine was recorded yesterday although the maximum temperature slipped (13.4C) again to be 0.5C below the April average. Late yesterday evening the wind backed from the southeast to the east and is quite brisk this morning. Overnight the cloud cover and warmer air meant that the thermometer did not drop below 8.5C, a very mild night compared with many this past week. The barometric pressure has been dropping for the past thirty six hours as a depression from the Atlantic approaches with its cold front already over Cornwall and at 0800 gave the lowest reading all month at 1001.7mb.
It is the warmest morning all month but notable is that after so little rain and now a drying easterly wind, the humidity level at 08.00 was 73%, the driest air at this time since June 6th 2016.
