Thu Thunderstorm Threat Timeline

Temperatures will briefly fall below freezing along the I-94 corridor and in southwestern to south-central WI tonight before rising back above freezing. A brief period of freezing rain is possible in those regions. North of the I-94 corridor, temperatures are expected to remain below freezing, allowing for ice accretions on elevated surfaces, trees, and powerlines.

A Winter Weather Advisory is in effect 1 AM to 9 AM Thursday morning for portions of central and east-central Wisconsin. There is potential for freezing rain in the Advisory area, with ice accretions mainly on elevated and untreated surfaces. Some slick spots will be possible into the Thursday morning commute. Rapidly rising temperatures post-dawn Thursday morning will quickly end the freezing rain threat and melt any associated ice.

Here are the expected freezing rain ice accumulations for late tonight into early Thursday morning. Some sleet could potentially mix in right as the precipitation starts late tonight, but should not measurably accumulate. This leaves freezing rain as the only noteworthy threat. Ice totals will be mainly on elevated / untreated surfaces, and will be heavily dependent on the exact temperatures.

Here are the Thursday afternoon / evening thunderstorm hazards and threat levels across our region.
