Remarks
Transmitter failed repeatedly during the heavy rain in the afternoon. Most data reconstructed from comparison with check gauge, consistency and surrounding observations. A full reset of the transmitter and consoles late afternoon seemed to cure the problem.

Daily Diary

A bright start with areas of high and medium cloud soon turned dull and overcast, as rain arrived from the west. This associated with a slow moving and active cold front, which brought the wettest day on record here (back to 1st Jan 2020) but possibly not quite the wettest 24 hour period (May 12th and 13th 2021). The front, and associated line convection eventually cleared through mid-late afternoon (surface front just after 17Z), with a clearance just in time for dusk leading into a clear evening. Some showers followed on behind overnight. A breezy S becoming W wind, with temperatures well below average for late September.
