Louisville Weather Alert: Severe Overnight Storms Could Bring Tornado & Flash Flood Danger—What You Need to Know

Louisville residents are facing a stormy stretch as a slow-moving cold front pushes across the Ohio Valley, keeping a Flood Watch in place through 9 a.m. Thursday and priming the metro for another round of strong to severe thunderstorms tonight. Morning outlook • Leftover downpours and ponding on roads will linger through the commute. • Temperatures hover in the low 70s with oppressive humidity. Afternoon warm-up • Skies briefly brighten, sending highs to 86-88 °F and allowing the atmosphere to reload with moisture. • South winds gusting 20-25 mph will funnel additional Gulf warmth into the city. Evening-overnight danger window • A line of storms is expected to fire along the front after 6 p.m. and sweep eastward between 8 p.m. and 2 a.m. • Main threats: damaging 60-70 mph wind gusts, pockets of hail, torrential rain capable of 1-2″ per hour and isolated tornado spin-ups. • Urban and low-lying areas already saturated from Wednesday’s deluge are most vulnerable to flash flooding. Friday and weekend trend • Cooler, drier air slides in behind the boundary Friday, dropping highs to the upper 70s and delivering a refreshing northwest breeze. • Sunshine dominates Saturday before another quick-hitting shower chance late Sunday as a weak disturbance races by. Preparedness checklist • Enable wireless emergency alerts and have multiple ways to receive warnings after dark. • Park vehicles away from large trees and secure loose outdoor items. • Never drive across a water-covered roadway—turn around, don’t drown. • Keep an eye on vulnerable neighbors who may need help reaching a safe shelter.
