Fall 2021 Precip Departures

Posted: 18 Nov 2021 05:33 AM

If you define the fall season as starting on 1 September, the featured map presents IEM computed precipitation total departures from average for this fall season to date. While it has been a very wet fall for many in the state, not all locations are even above average for the period. The notable exception shown is Dubuque with a 1.79 inch negative departure due to a rather dry September. The caveat to the dry areas shown for this period is the amount of precipitation that fell during a very wet August. So the end result is that while drought conditions still due linger in the state, the effects felt during this time of the year are rather minimal with the growing season long over and nil evaporative demand due to cold-season temperatures.
