Image Description

NWS Green Bay graphic displays two maps for Wisconsin alongside severe weather threat details. The left map, valid through 7 AM, highlights a Level 3 Enhanced Risk in orange for north-central Wisconsin cities such as Crivitz, Rhinelander, and Antigo. The right map, valid today, outlines a Level 1 Marginal Risk in green over northern areas, a Level 2 Slight Risk in yellow across central regions, and a Level 3 Enhanced Risk in orange in the south covering Wautoma, Oshkosh, and Manitowoc. Center text states: "There are ongoing thunderstorms across the area this morning. Additional development is expected throughout the morning hours ending midday. Additional scattered storm development is possible in the mid to late afternoon hours today. Ensure your Wireless Emergency Alerts (WEA) is turned ON!" Below, potential hazards include isolated tornadoes, damaging winds of 50-70 mph, and hail up to 1 to 2 inches. Forecast confidence is high that storms develop, but lower for intensity.
