This Week's Weather & Pests

Lingering humidity early in the week contrasted with cooler, drier weather as high pressure settled over Wisconsin during the last days of August. Daytime temperatures in the 80s were replaced by comfortable highs in the 70s, while nighttime lows cooled to the 40s and 50s. Rain showers continued to slow alfalfa and oat harvesting, though mild conditions promoted corn and soybean maturation. Following this summer's pattern of unseasonable warmth and plentiful precipitation, crop development remains one to two weeks ahead of last year and the long-term average. Crop condition ratings are still exceptionally favorable, despite increasing fungal disease problems intensified by high humidity and frequent rain, with 86-90% of the state's alfalfa, corn, potato and soybean acreage reported in good to excellent condition. The early-September forecast calls for a return to above-normal temperatures, which should expedite the corn silage harvest and accelerate crops toward maturity.
