April Statewide Ranks
01 May 2025 05:30 AM
The IEM produces unofficial daily statewide (spatially averaged) estimates of precipitation. NCEI produces a more official statewide estimate as well, but only publish monthly data delayed by a week or so. The featured map presents what the IEM computes for statewide April 2025 precipitation ranks with a value of one indicating the wettest April since 1893 for the state. The map shows remarkable variability with Iowa and certainly Nebraska missing out on the very wet month that just completed. There's an additional accounting quirk that should be mentioned and that being these "daily" values represent 24 hour totals ending at about 7 AM, so to match most current NWS COOP reporting. You can find these statewide values available for download along with the other long term climate sites tracked by the IEM.
