IA/IL/MO|Tri States|🏜️Drought Outlook🏜️

2025-09-04. From National Drought Mitigation Center: Widespread degradations were made across the region in response to precipitation shortfalls (ranging from 2 to 4+ inches) during the past 30-day period. Record to near-record dryness (for the past 30-day period) was observed at numerous observing stations across the region including Cincinnati Airport (AP), Ohio (-2.71 inch departure from normal; driest on record), Columbus AP, Ohio (-3.1 inches; driest on record), Springfield, Illinois (-3.21 inches; 2nd driest on record), and Springfield AP, Missouri (-3.45 inches; driest on record), according to the SERCC. Additionally, numerous drought impact reports (agricultural sector) were reported during the past seven days to the National Drought Mitigation Center’s Condition Monitoring Observer Report (CMOR) system—primarily from southern Missouri, north-central Kentucky, and southern Ohio. For the week, average temperatures were well below normal (2 to 15 degrees F) across most of the region, while northern Minnesota saw positive anomalies ranging from 2 to 6+ degrees F above normal.
