Below Ave Upcoming GDDs

Posted: 23 Aug 2019 05:35 AM

A wet spring and late planting of most agricultural crops in the state already have crop development running behind average by a week or more. The forecast for the upcoming week looks rather cool and the featured chart presents departure from long term average of accumulated growing degree days based on NWS forecast daily high and low temperatures from the National Digital Forecast Database. Except some portions of southern Indiana, the entire domain is indicated with below average accumulation with the largest departures found in west central Iowa. The growing concern is that an early frost in September could be trouble for crops yet to reach maturity. At this point, such an event does not appear likely at least through the first week of September.
