During the bursts of very strong sunshine on Wednesday the thermometer rose to its highest all month with a maximum of 23.2C at 15.04 being 2.6C above my long-term average. The day was dry and the UV peaked in the ‘High’ category again. The past night was mild that saw the thermometer not drop below 12.5C at 04.46, just before sunrise in Marlborough at 04.50, being 2.3C above average.
Thursday revealed a bright start to the new day with thin high cloud. Since just before 05.00, the track of cloud on the radar showed much thicker cloud just skirting to the west of our area but just after 07.30 much thicker cloud drifted in front the southeast as a fragmented rain band edged closer.
The high pressure has moved slowly away allowing low-pressure to the west begin to dominate our weather with the rain radar showing a large area of rain edging closer from the southeast. The wind, currently from the southeast, will veer into the south later today. The barometric pressure had fallen away to 1011.5mb at 08.00, down 11mb since its peak Monday
The last four dry days have seen the loss of equivalent rainfall through evaporation from the ground and plant life exceed 3mm daily. The rainfall this month, so far, totals 25.8mm against my 41-year average of 52.9mm whilst 33.8mm of equivalent rainfall has evaporated into the atmosphere.
