Iowa Crop Progress and Condition Report

DES MOINES, Iowa (June 5, 2023) – Iowa Secretary of Agriculture Mike Naig commented today 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.

“In between spotty thunderstorms last week, farmers took advantage of the opportunity to begin applying crop protection products, adding side-dress fertilizer, and cutting and baling hay,” said Iowa Secretary of Agriculture Mike Naig. “Widespread rain totals were below average and much of the state remains abnormally dry, but forecasts do indicate chances for precipitation and a return to more seasonal temperatures.”

The weekly report is also available on the USDA’s website at nass.usda.gov.

A large-scale high-pressure system over Canada produced anomalous southeasterly to easterly flow across Iowa towards the end of the reporting period. Widely scattered pop-up thunderstorms also formed over portions of Iowa on several days, though rainfall was below average. Unseasonably warm conditions continued with positive departures of up to 12 degrees in northwest Iowa; the statewide average temperature was 73.7 degrees, 8.3 degrees above normal.

Sunshine and southeasterly winds continued through Sunday (28th) afternoon with daytime temperatures in the low 80s statewide. Clouds increased in southwestern Iowa overnight as scattered showers formed near sunrise on Monday (29th) before dissipating in west-central Iowa by mid-morning. Partly cloudy skies remained in western Iowa with afternoon highs in the mid to upper 80s at many stations. A disturbance moving across the Dakotas produced isolated thunderstorms over northwestern and north-central Iowa late in the day and through the early morning hours of Tuesday (30th). Only a handful of stations observed rainfall totals above 0.10 inch though Mapleton (Monona County) measured 0.78 inch. Storms refired in western Iowa as temperatures pushed into the upper 80s with southerly flow.

Pockets of showers and thunderstorms formed from southwest to central Iowa into Thursday (1st) morning with afternoon heat producing scattered pop-up storms across the state several hours later.

Partly to mostly cloudy skies persisted into Friday (2nd) as temperatures rose into the upper 80s at many stations. In the presence of ample low-level moisture and instability, afternoon thunderstorms again fired over much of Iowa.
