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.

“Summer officially begins this week, and Iowans can expect temperatures that match the season. After the frustrating planting delays, crops seem to be catching up nicely,” said Secretary Naig. “Both corn and soybeans will continue to benefit from the forecasts indicating unseasonable warmth with above average chances for rain through the end of June.”

The weekly report is also available on the USDA’s website at

The last full week of astronomical spring brought warmth and unseasonable dryness to most of Iowa. Stations in eastern Iowa did not report any measurable rainfall with widespread departures between 0.50 to 1.00 inch elsewhere. Temperatures were three degrees above normal south-central and northwest; the statewide average temperature was 71.9 degrees, 1.8 degrees above normal.

Gusty northwesterly winds developed into Sunday (9th) afternoon under sunny skies and daytime temperatures in the upper 70s and low 80s. Spotty clouds passed through eastern Iowa into Monday (10th) with morning lows in the 50s statewide. Afternoon conditions were pleasant with variable winds and temperatures in the low to mid 70s at most Iowa stations. Winds shifted southerly overnight with Tuesday (11th) morning lows ranging from the low 50s southeast to mid 60s northwest as a low pressure center skirted the Iowa-Minnesota border. Light showers formed along the low’s attendant cold front, though totals were under 0.10 inch across northern and central Iowa as rain dissipated farther east. Afternoon temperatures rose into the upper 80s in northwestern Iowa even as winds shifted northwest behind the front. Stations in eastern Iowa remained in the upper 70s and low 80s. Morning lows on Wednesday (12th) held in the 60s across the state as southerly winds brought in warmer temperatures and higher dewpoints. An outflow boundary from convection in Minnesota fired stronger storms in northeastern Iowa just after noon. These storms continued east with several high wind reports as isolated, severe warned supercells formed in western Iowa and slowly moved south. Hail in the 1.50-2.50-inch diameter range was observed from Sioux City (Woodbury County) to Council Bluffs (Pottawattamie County) with a 3.50-inch hailstone in Onawa (Monona County). Heavier rainfall was also observed along this southward track with 0.63 inch in Blencoe (Monona County) to 1.03 inches in Pacific Junction (Mills County). Stations in the northeast corner also accumulated higher totals with 0.44 inch at Decorah Municipal Airport (Winneshiek County) and 0.65 inch at Lansing (Allamakee County); amounts in between these two regions were in the 0.10-0.25-inch range where rain fell.

Thursday (13th) started unseasonably warm and humid with morning temperatures in the upper 60s to low 70s. A cold front dropped through the state over the next several hours, encountering a warm and unstable airmass over southern Iowa. Supercells quickly developed along with large hail and localized heavy rain. Observers in Keosauqua (Van Buren County) reported 3.00-inch diameter hail while an 80-mph wind gust was observed farther northeast in Oakville (Louisa County). Six stations across Des Moines, Lee and Van Buren counties reported totals ranging from 1.09 inches to 1.73 inches with amounts in the 0.40-0.80-inch range in adjacent locations. Nighttime conditions cooled behind the front with morning lows in the mid to upper 50s over northern Iowa. Friday (14th) was unseasonably warm with low relative humidity and air temperatures in the upper 80s across southern Iowa under sunny skies; temperatures to the north were five to 10 degrees cooler. Winds shifted easterly overnight as an organized complex of thunderstorms, known as a Mesoscale Convective System (MCS) approached Iowa from Nebraska. The MCS brought measurable rain to western Iowa through Saturday (15th) morning and then into the afternoon hours in eastern Iowa. A secondary disturbance with strong to severe thunderstorms moved into Iowa during the evening hours and sped through central to northeast Iowa overnight. Except for Iowa’s southeast corner, totals for the two systems reported at 7:00 am on Sunday (16th) were in the 0.30-to-0.75-inch range with the highest totals north and in the southwest quadrant; Clarinda (Page County) hit an inch with 1.52 inches reported in Kesley (Butler County) and Shenandoah (Page County).

Weekly precipitation totals ranged from no accumulation at multiple stations to 2.59 inches in Spirit Lake (Dickinson County). The statewide weekly average precipitation was 0.62 inch while the normal is 1.19 inches. Little Sioux (Harrison County) reported the week’s high temperature of 95 degrees on the 12th, 13 degrees above normal. Iowa City (Johnson County) reported the week’s low temperature of 43 degrees on the 11th, 15 degrees below normal.
