Drought — Chickasaw, Iowa

2024-03-01 to 2024-03-31 · Chickasaw, Iowa

Event narrative

While total monthly precipitation of 2 to 2.5 was near normal for Chickasaw County through March, long-standing abnormally dry conditions resulted in extreme (D3) drought persisting across nearly all of the county.

Wider weather episode

Ongoing abnormally dry conditions eased a bit through March in northeast Iowa. Since initial drought issuance on June 1st, 2023, total liquid precipitation through March neared 15, which was more than 9 below normal. As a result, widespread severe (D2) to extreme (D3) drought enveloped all of northeast Iowa at the onset of March. Volunteer observers report 7 to 10 days of measurable precipitation in March across northeast Iowa, resulting in total monthly liquid precipitation near 2. Most of this fell in a period of one week from March 21st to March 27th. Highest weekly storm totals reported by volunteer observers were 1.5 in New Hampton (Chickasaw County), 1.25 in Decorah (Winneshiek County), and 1.03 in Postville (Allamakee County). These near normal monthly precipitation totals resulted in the extreme (D3) drought area shrinking slightly, though all of northeast Iowa still remained under at least severe (D2) drought conditions by the end of March.
