Bow Echo Powers Severe Gusts Toward Milwaukee-Chicago Corridor — SevereWX

A potent bow echo is barreling across northeast Wisconsin, with new storm clusters firing southeast toward central Lake Michigan and beyond. The Storm Prediction Center's latest Mesoscale Discussion flags a sharp rise in severe potential through early afternoon across southeast WI, northeast IL, southwest Lower MI, and northeast IN.

Radar and satellite imagery show elevated convection and towering cumulus bubbling in a corridor of extreme instability—2000-4000 J/kg MLCAPE paired with steep midlevel lapse rates and 50+ kt shear. Multiple clusters could merge into severe thunderstorms, delivering swaths of 65-80 mph damaging winds, isolated 1-1.75 inch hail, and potential tornadoes up to 90 mph.

The prime zone stretches from eastern WI through northeast IL, across southern/central Lake Michigan into southwest MI and northwest IN. Timing remains tricky, but SPC pegs watch issuance odds at 60%, likely by midday.

This setup echoes recent volatile bouts near the lake shores, where quick upscale growth can catch communities off guard. Keep eyes on radar as storms evolve.
