Overview
- Storm Prediction Center outlooks place parts of the Ohio Valley, including areas near Louisville, under an enhanced risk for severe storms late Sunday night.
- Forecasters expect the most active window after midnight into early Monday from Indiana and Kentucky through Cincinnati, with the threat shifting into Michigan before daybreak and into the Mid-Atlantic and Southeast during Monday.
- Damaging straight-line winds are the primary hazard with gusts capable of causing power outages, and brief, isolated tornado spin-ups cannot be ruled out.
- A sharp post-frontal cooldown follows, dropping 60s–70s to 30s with a hard freeze likely by Tuesday in many locations, and rain changing to snow or flurries in some areas.
- Ahead of the system, Wind Advisories are in effect in parts of the Northeast and Mid-Atlantic, Colorado faces a Red Flag Warning for critical fire weather, and several local stations have declared Impact/Alert days.
