Iowa Crop Progress and Conditions Report

Week of June 1-7, 2020

DES MOINES, Iowa (June 8, 2020) – Iowa Secretary of Agriculture Mike Naig today commented on the Iowa Crop Progress and Condition report released by the USDA National Agricultural Statistics Service. The report is released weekly from April through November.

“Above normal temperatures across much of the state last week allowed for rapid crop development,” said Secretary Naig. “Some pockets of dryness are popping up across parts of Iowa. Those areas could see some relief this week as the remnants of Tropical Storm Cristobal brings chances of rain."

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

Meteorological summer began on the first of June, and on cue, unseasonable warmth returned to Iowa. Positive temperature departures were generally in the range of six to 10 degrees, with up to 12 degrees reported across western Iowa. The statewide average temperature was 76.2 degrees, 9.4 degrees above normal. Drier conditions were also reported across Iowa’s southwestern two-thirds on the order of 1.00 to 2.00 inches below normal. Pockets of above average rainfall were reported in northeast Iowa.

Clouds cleared west to east during the afternoon hours on Sunday (31st) with blustery southerly winds. Daytime highs reached into the low to mid 70s. Clouds began to increase as a warm front lifted through the state into Monday (1st) morning. Lows remained in the 60s with light to moderate rain showers reported across portions of the state. Heavier rain fell across northern Iowa, especially Worth through Howard counties, where Elma reported 0.92 inches. Amounts quickly tapered off to a few tenths of inch in the two immediate southwest counties. Sunny skies and a strong southwesterly wind boosted highs into the low 90s across northwestern Iowa while temperatures in the southeast remained in the 80s. Overnight temperatures remained warmer than average, in the upper 60s and low 70s, under starry skies. Tuesday (2nd) was the warmest day of the year so far, with daytime highs in the mid to upper 90s across a majority of Iowa. The hottest conditions were found in northwestern Iowa, where some stations reported triple digit heat indices. Multiple stations broke their high temperatures for the date with the statewide average high of 92 degrees, 15 degrees above normal. Showers and some severe thunderstorms began to fire along a strong frontal boundary along the Iowa-Minnesota border during the evening hours. A few isolated severe thunderstorms re-fired across southwestern and central Iowa in the early morning hours of Wednesday (3rd). The system moved southeast through Iowa and cleared the state just before noon. Rain totals were highest in eastern Iowa where multiple stations reported totals over an inch with lighter amounts farther west; Davenport Municipal Airport (Scott County) reported 1.91 inches.

Thursday (4th) was another active weather day as an initial line of thunderstorms popped up in the evening across eastern Iowa. Many of the storms turned severe and produced multiple reports of hail and straight-line winds. Locally heavy downpours were also observed. A second round of strong thunderstorms moved into north-central and eastern Iowa overnight into Friday (5th). Some thunderstorms turned severe and produced over 40 reports of severe straight-line winds as they sped through central Iowa.
