Here's an overview of the next weather system, Wednesday evening through Thursday evening.
A wintry mix of sleet, freezing rain, and possibly wet snow arrives north of I-94 late Wednesday evening, transitioning to all rain / freezing rain into Wednesday night. No meaningful snow / sleet accumulation expected, freezing rain will be the main story with a glaze up to a tenth of an inch possible. Locally higher amounts to two tenths of an inch cannot be completely ruled out (30% chance north of a WI Dells to Sheboygan line). The majority of the ice accretion will occur on elevated surfaces, but some slick spots will be possible during the Thursday AM commute, particularly further north in the region. This should be an all-rain event along and south of the I-94 corridor. Exact details will depend on the track of the low pressure system.
A conditional threat for strong to severe thunderstorms is present on Thursday in the afternoon and evening hours. As the track of the low pressure system becomes clearer, we will begin to diagnose the threats (hail, tornadoes, or strong wind gusts) and the exact threat level.
