The anticipated and significant rainfall event is at hand with amounts expected to be over an inch for much of Iowa with isolated amounts approaching 3-4 inches over far eastern Iowa during today and into Saturday. For some places, like Marshalltown, this event could perhaps produce the maximum daily precipitation total for the year. The present max is 1.44 inches back on 22 April. The featured chart presents some metrics on the max one day precipitation event based on automated station data back to the mid 1990s. One other event is shown in November with a few in October as well, so an event on 4 November is not too far from what has happened in the past. Oh, and some light snow is expected to wrap into the northwestern corner of the state Friday night! That is certain something germane to November!
Updated: The Friday total for the site was 1.48 inches, so largest for the year.
