DES MOINES, Iowa – 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 published weekly from April to November.
“A cold breeze late last week caused temperatures to drop well below normal as the first rain showers of the season swept over nearly fully harvested corn and soybean fields,” Minister Naig said. “Farmers are focused on completing field work in the fall before the frost sets in as forecasts show colder conditions by the end of November.”
The weekly report is also available on the USDA’s website at nass.usda.gov.
Harvest was mostly complete, with 5.6 days suitable for field work in the week ended November 13, 2022, according to the USDA, National Agricultural Statistics Service. Fieldwork included packing fall tillage, applying fertilizer, pressing stalks, and hauling and spreading manure.
The moisture status of the topsoil was rated at 18 percent as very low, 35 percent as too low, 45 percent as sufficient and 2 percent as excessive. The subsoil moisture is rated at 25 percent very low, 38 percent low, 36 percent sufficient and 1 percent excess.
Corn harvest for grain harvest was 95 percent complete, eight days ahead of last year and 12 days ahead of the average. The moisture content of field corn harvested for grain was 16 percent. Farmers in northeast and south-central Iowa still have over 10 percent of their grain crop corn that has yet to be harvested.
Livestock were mostly fine, although the sudden move to colder temperatures caused some stress.

Iowans experienced a dramatic shift from unusual warmth to winter-like conditions towards the end of the period; The nationwide average temperature was 39.2 degrees, 1.6 degrees above normal. Widespread rains and some snow flurries brought additional moisture to soil profiles across much of the state. East and Northwest Iowa reported above-average totals of nearly an inch, while central state saw departures of nearly 0.50 inches.
Patchy cloud cover was reported over parts of Iowa through Sunday afternoon (6th) as a weak low-pressure center spread along the Iowa-Missouri border. Daytime temperatures held in the 50’s as the southwest wind turned to a more westerly direction. The night sky was clear with morning lows ranging from the low 20s in the north to the mid 30s in the south. Monday (7th) was cool with afternoon highs in the low 40’s over northern Iowa while southern Iowa recorded temperatures in the low 50’s. Clouds gradually increased during the late night hours as an easterly wind persisted, but gradually turned southeast as a disturbance approached northwest Iowa. Tuesday (8th) morning lows were near average as clouds prevented further overnight cooldown; mid to high 40’s were observed in western Iowa while upper 30’s were present in eastern Iowa where skies were still clear. Showers and some thunderstorms formed over northwest Iowa throughout the day as gusty southeasterly winds developed statewide. Favorable rainfall levels were observed in several northwestern counties, with two stations in Le Mars (Plymouth County) measuring from 1.00 inches to 1.20 inches; Totals continued to decline to the southeast, with nearly 30 stations erupting at least 0.25 inches. A thick cloud cover persisted overnight as a warmed air mass, along with higher relative humidity, encroached on the Midwest. Morning lows, reported at 7:00 am Wednesday (9th) in western Iowa, were in the upper 50s with some low 60s ahead of an approaching Iowa cold front; Those readings were up to 30 degrees warmer than normal with a national average low of 43 degrees, 13 degrees above normal. Low clouds and muggy conditions continued into the afternoon and evening hours.
Southerly winds increased ahead of the cold front that swept across Iowa on Thursday (10th). Showers and thunderstorms formed in eastern Iowa, where daily highs stretched into the upper 70s. The showers spread across the southeastern quarter of Iowa through the rest of the day and overnight through Friday (11th). More than 20 stations observed at least one inch, with general totals between 0.20 and 0.60 inches at most stations reporting rain; Dubuque (Dubuque County) measured 1.06 inches, while a gauge near Lisbon (Linn County) observed 1.49 inches. Cold Canadian air rushed in behind the cold front, with afternoon highs on Saturday (12th) ranging from 20 to 30; The nationwide average high was 28 degrees, 20 degrees below normal. Snow flurries fell across much of Iowa throughout the day as northwesterly winds and thick stratus clouds persisted. Winds became variable overnight into Sunday (13th), with temperatures falling only five to 10 degrees and skies in the south west were clear. Light snow accumulations ranging from 0.1 inches in Orange City (Sioux County) to 1.0 inches in Waterloo (Black Hawk County) were reported at a handful of stations.
