Weather log for April 2020

[Note.
Due to illness, all days of this month were missed for some Manilla values. No values were noted for cloud or soil temperature; mean values shown for the month are estimates only. Daily maximum and minimum air temperatures were estimated by regression on values from Tamworth Airport Automatic Weather Service.]

April weekly mean temperatures were one or two degrees below normal, except in the final week.
There were five rain days, with the highest reading of 18.4 mm on the 11th.

Comparing April months

The mean monthly temperature, at 17.7°, was rather low, half a degree below normal. The mean daily maximum, at 24.7°, was one-and-a-half below normal, while the mean daily minimum, at 10.7°, was normal.
Apart from rainfall, the only moisture indicator available this month is daily temperature range. At nearly 2° narrower than normal, it implies more moist conditions than the rainfall. The rainfall total of 32.8 mm was at the 50th percentile for April, which is rather below the average (44 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. The gauge failed again during February (25/02/2020 ), but was repaired on 11/3/20.
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.
