Individual Severe Weather Hazards

Heat & Humidity Through Monday

Areas of dense fog with visibilities as low as 1/2 mile have developed near & south of I-94 and US-18 this morning. A Dense Fog Advisory is in effect until 8 AM. Slow down, use low beam headlights, and allow for extra following distance if encountering fog during the morning commute.

Overnight severe storms have been heavily delayed by dry air and capping. Storms are now projected to move through between 6AM and Noon this morning, with more potential for scattered storms later today.

Thunderstorms are expected to cluster over northern WI and move southward with time, capable of all hazards. Afternoon redevelopment will be conditional and will depend upon if we can destabilize after the morning storms.

A Heat Advisory will run from 10AM to 9PM today for heat indices between 100 and 102 degrees. Heat headlines today will depend upon morning storm coverage. Less storm coverage = higher heat indices, and potential expansions/upgrades to the heat headlines.
