Iowa Crop Progress and Condition Report

June 22 - 28, 2026

DES MOINES, Iowa (June 29, 2026) - Iowa Secretary of Agriculture Mike Naig commented on the Iowa Crop Progress and Condition Report released by the USDA National Agricultural Statistics Service. The report is released weekly April through November. Additionally, the Iowa Department of Agriculture and Land Stewardship provides a weather summary each week during this time.

"Thunderstorms over the weekend brought isolated reports of hail and straight-line winds, but also much-needed rainfall across northern Iowa. This week, a heat dome will push temperatures into the 90s. Daytime highs and overnight lows could run more than 10 degrees above average for late June and early July. The warm summer weather will give the crops a boost," said Secretary Naig. "As we celebrate America's 250th birthday with community events, backyard barbecues and fireworks, we're reminded that agriculture has always been central to our nation's story. Our farmers have helped feed, fuel and sustain America since its founding, and they will continue to play a vital role in our nation's strength, security and prosperity for the next 250 years."

Portions of northwest and southeast Iowa experienced wetter than normal conditions with the rest of the state drier than normal.

Moderate showers persisted throughout Sunday (21st) afternoon in central and eastern Iowa as a low pressure center exited the state.

Temperatures in southern and western Iowa held in the low to mid 50s under clear skies. Wind turned southerly and became gusty through the day as clouds increased, helping temperatures push into the upper 70s and low 80s with rising humidity. A cold front moved into the northwest corner after midnight on Wednesday (24th), producing scattered showers and thunderstorms that propagated southeast across the state into late morning.

Spotty thundershowers formed in southwestern Iowa around sunrise on Thursday (25th), quickly dissipating over a few hours.
