I am not sure if this is a meteobridge bug or a weather underground bug.
On my weather station: https://www.wunderground.com/dashboard/pws/KCASANJO507
If you look at the rainfall graph on 5/17, you see 0.01" of rain as midnight- approaches, also 0.01" of rain is reported for the day.
If you look at 5/18, you see that the rate of rainfall at midnight+, it shows 0.02"/hour, but the rainfall at 0" of rain. 0.01" of rain somehow got lost.
I was running: Meteobridge 4.3 (Mar 8 2020, build 13423), FW 1.4
I will update to the latest, but I doubt that will correct this bug if it was not previously known. This is going to be a hard bug to reproduce.
WeatherUnderground ignores rain reported at midnight.
