This Week’s Weather & Pests

A warmer, unsettled weather pattern arrived in Wisconsin, increasing topsoil moisture but slowing or halting fieldwork and causing local flooding along the lakeshore counties. Some of the heaviest rain (6 to 7 inches) fell across the east-central and southeastern regions May 17, while most areas received anywhere from 1 to 3 inches during the week. In Sheboygan County, the City of Plymouth recorded 7 inches of rain Sunday, and a reading of 2.99 inches at Milwaukee Airport set a new daily record. After the rain ended mid-week, planting of corn, oats, potatoes, soybeans and spring vegetables quickly resumed.

This spring’s rapid planting pace continued to progress 1-2 weeks ahead of the long-term average, with 81% of the state’s intended corn acres and 61% of the soybean crop already in the ground. A warming trend expected next week, including several days of afternoon highs exceeding 80°F for the first time this season, should improve conditions for crop emergence and growth.
