DES MOINES, Iowa (June 7, 2021) – 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.

“After a relatively cool end to May, above-average temperatures arrived at the end of last week, which will help push the crops along,” said Secretary Naig. “The forecast shows warm temperatures and limited chances of rain so we’re continuing to keep a close eye on the drought conditions.”

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

The first week of meteorological summer brought warmer conditions across much of Iowa with a statewide average temperature of 69.9 degrees, 3.7 degrees above normal. Dryness also persisted with a southwest to east-central swath of the state reporting no measurable rainfall. Statewide precipitation deficits were well over an inch with smaller departures in the northwest.

Rain showers dissipated into the afternoon hours on Sunday (30th) as a weak disturbance pushed eastward through Iowa. Afternoon temperatures were in the upper 50s northwest to upper 60 southeast where sunny skies prevailed. Foggy conditions were reported in southern Iowa early on Monday (31st) as overnight lows dropped into the upper 40s and low 50s. Rainfall reports from the previous 24 hours were generally light and located across Iowa’s northwestern third; pockets approaching 0.50 inch were found along the Iowa-Nebraska border and in north-central Iowa with totals around or below 0.25 inch elsewhere. Daytimes highs on Memorial Day were near seasonal for some parts of Iowa, though southern Iowa observed low to mid 60s. Light showers formed in southeastern Iowa early on Tuesday (1st), along with a line of thundershowers later in the day in northern Iowa, which produced heavier totals in Chickasaw County. Under light southerly winds, temperatures reached into the upper 70s with partly cloudy skies. Overnight lows into Wednesday (2nd) remained in the mid 50s with light and variable winds. Conditions during much of the day were pleasant, with highs in the upper 70s and low 80s as a dry pattern set up across the state.

Dry, westerly winds and sunny skies helped push temperatures into the low 80s on Thursday (3rd) as high pressure built in over the region. Winds shifted to a southerly direction overnight into Friday (4th), with dew points rising in response to more atmospheric moisture streaming north. Under stable and warm conditions, temperatures reached into the mid 90s in northwestern Iowa while the upper 80s persisted in the east. Clear conditions continued into Saturday (5th) with morning lows in the mid to upper 60s, up to fourteen degrees above average. With a lack of overnight cooling, afternoon highs climbed into the 90s, producing the warmest day of the season thus far; the statewide average high was 91 degrees, 13 degrees warmer than normal. Starry skies and a light southerly wind continued into Sunday (6th) morning along with very warm temperatures. Decorah (Winneshiek County) observed a morning low of 70 degrees, 14 degrees above normal, while the statewide average low was eight degrees above normal at 65 degrees.

Weekly precipitation totals ranged from no accumulation at many Iowa stations to 0.53 inches near New Hampton (Chickasaw County). The statewide weekly average precipitation was 0.06 inch while the normal is 1.17 inches. Several western Iowa stations observed the week’s high temperature of 97 degrees on the 4th and 5th, on average 18 degrees above normal. Chariton (Lucas County) reported the week’s low temperature of 34 degrees on the 31st, 19 degrees below normal.
