“Iowa’s crop progress continues to be ahead compared to past years with 97% of soybeans and 87% of corn harvested across the state,” said Secretary Naig. “The weather over the next week looks favorable and should allow farmers to make good progress in the field as harvest wraps up.”

Crop Progress
Rain and snow early in the week along with cooler temperatures limited Iowa farmers to 5.3 days suitable for fieldwork during the week ending November 1, 2020, according to the USDA, National Agricultural Statistics Service. Fieldwork activities reported included harvesting corn and soybeans, baling corn stalks, applying fertilizer and manure, moving grain to town and tillage.
Topsoil moisture condition rated 13% very short, 28% short, 58% adequate and 1% surplus. Subsoil moisture condition rated 19% very short, 34% short, 46% adequate and 1% surplus.
Only 13% of Iowa’s corn for grain crop remains to be harvested, over 3 weeks ahead of last year and 13 days ahead of the 5-year average. Statewide, the moisture content of field corn being harvested for grain fell 1 percentage point to 15%. Farmers in northwest, north central and west central Iowa have less than 10% of their corn for grain remaining to be harvested while farmers in south central Iowa still have over 30% to be harvested.
Only 3% of Iowa’s soybean crop remains to be harvested, just over 3 weeks ahead of last year and 2 weeks ahead of average. Farmers in northwest, north central and west central Iowa have few fields left to harvest with 1% or less of their soybeans remaining. In contrast, farmers in the southern one-third of the state have 9-10% of their soybeans left to be harvested.
Livestock producers continue to allow cattle to graze on corn stalks.

Besides light snow falling across much of the state early in the week, unseasonably dry conditions prevailed over Iowa with the driest conditions reported in eastern Iowa. Precipitation departures of up to 0.70 inch were observed in the state’s southeast corner.
Overcast, cold and windy conditions persisted into Sunday (25th) as light snow fell across northwest Iowa. Daytime highs ranged from the upper 20s northwest to low 40s southeast. The system continued to move through Iowa overnight into Monday (26th) with at least an inch of snow reported at many stations in the state’s western half. Higher totals were reported in the northwest quadrant with Pocahontas (Pocahontas County) measuring 2.4 inches while Sibley (Osceola County) observed 5.6 inches. Totals tapered off in eastern Iowa with accumulations generally under 0.25 inch. Afternoon temperatures remained well below normal under partly sunny skies and light northerly winds.

While still unseasonably cool, temperatures reached into the upper 30s and low 40s across much of Iowa.
Thursday (29th) saw persistent cloud cover over much of central and eastern Iowa with afternoon peeks of sunshine and temperatures finally warming into the 50s. A weak cold front dropped southeast through Iowa over the rest of the day shifting winds to a northerly direction during the late evening hours as the front passed. Gusty winds developed overnight into Friday (30th) with morning lows dipping into the low 30s northwest to low 40s southeast. Clouds cleared from west to east through the day as a high pressure center dominated the upper Midwest. Southwesterly winds on the backside of the high were somewhat gusty and increased into Saturday (31st) morning as a low pressure system approached from the west. The low’s attendant warm front pushed northeast through Iowa during the afternoon hours, lending to pleasant and seasonal temperatures. Highs across the state’s southern half reached into the upper 60s with a statewide average high of 64 degrees, 10 degrees above normal. A close, secondary high pressure system moved in behind the low pressure over the upper Midwest forcing strong and gusty northwesterly winds under clear skies. Morning lows reported at 7:00 am on Sunday (1st) ranged from the upper 20s in northwest Iowa to mid 30s in the southeast.
Weekly precipitation totals ranged from no accumulation at several stations in northeastern Iowa to 0.45 inch at Mapleton No. 2 (Monona County).
