March 2020: cool, moist

Weather log for March 2020

[Note.
Due to illness, 45 days were missed for some Manilla values, beginning in March (23/3/20). No values were noted for cloud or soil temperature; daily maximum and minimum air temperatures were estimated by regression on values from Tamworth Airport Automatic Weather Service.]

March weekly mean temperatures were near normal, but cooler in the second week.
Cloudy skies, with high dew points and rain came early and late in the month. There were nine rain days, with the highest reading of 19.0 mm on the 26th.

Comparing March months

The mean monthly temperature, at 21.8°, was rather low: cooler than in the last six March months. Days, at 28.6°, were third coolest for March in the new century, only March of 2001 and 2003 having cooler days.
Most moisture values were rather higher than in March of 2018 or 2019. The rainfall total of 53.2 mm was at the 60th percentile for March (and near the average (53 mm)).

Drought

I will report separately on the on-going drought.


Data. A Bureau of Meteorology automatic rain gauge operates in the museum yard. From 17 March 2017, 9 am daily readings are published as Manilla Museum, Station 55312.  These reports use that rainfall data when it is available. Recording resumed on 20 July 2019. Unfortunately, the gauge failed during February (25/02/2020 ). Until its repair on 11/3/20, I used my own gauge.
My estimates of early morning dew point have drifted anomalously low. From August 2019, I use data from the Tamworth Airport published graphs.
All other data, including subsoil at 750 mm, are from 3 Monash Street, Manilla.
