First Iowa Crop Progress Report Issued

Fields remained wet across most of Iowa during the week ending April 5, 2020, according to the USDA, National Agricultural Statistics Service. Statewide there were 2.7 days suitable for fieldwork. Wet conditions slowed field work activities; however, there were reports of producers applying anhydrous, spreading manure and planting oats.
Topsoil moisture levels rated 0 percent very short, 1 percent short, 77 percent adequate and 22 percent surplus. Subsoil moisture levels rated 0 percent very short, 1 percent short, 77 percent adequate and 22 percent surplus. Eight percent of the expected oat crop has been planted, 5 days ahead of last year but 2 days behind the 5-year average.
Pastures and hay have started to green. Livestock conditions were generally good with calving going well for most cattle operations.

Deficits across much of the state were between 0.20 – 0.60 inch. Temperatures were near normal statewide with an average temperature of 43.0 degrees, 0.10 degrees below normal.
A strong low pressure system moving through the upper Midwest brought windy conditions through most of Sunday (29th). Winds remained brisk out of the northwest with clouds clearing as a weak high pressure system moved into southwest Iowa.
Daytime highs reached into the upper 50s in the southwest to upper 30s northwest. With high pressure dominating the region, winds calmed under clear skies into Monday (30th) morning. Temperatures during the day were well above normal with western Iowa reporting mid to upper 60s, eight to twelve degrees above average. The average statewide high was 61 degrees, seven degrees above normal. Warm and partly cloudy conditions continued into Tuesday (31st) with light and variable winds. Daytime highs were held to the mid 40s and low 50s along the Iowa-Illinois border, where cloud cover was present. Clear skies helped push highs into the mid 60s in southwestern Iowa. The pattern began to shift during the late-night hours through Wednesday (1st) as showers and a few thundershowers formed across northwestern Iowa. The complex moved through central and eastern Iowa before dissipating in the early afternoon hours. Strong southerly winds and clearing skies allowed highs to reach into the low 70s in southwest Iowa, while temperatures remained in the 50s in eastern Iowa; in between, stations reported 60s and sunny conditions. Overnight temperatures into Thursday (2nd) remained unseasonably warm with the average low at 37 degrees, four degrees above normal.
