The rain which fell during the missing 2 to 3 o’clock hour seems not to have been captured by the WeeWX database. If the console is not correct then nothing down stream of it can be correct either, so no need to be concerned with that. . The discrepancy between the console and database is .21”, and it happened on the day of the daylight saving time change. For the previous day of that rain event, there is no discrepancy.
That’s what I know. Why is the question. Thanks for your input.
