Kentucky – Bright sunshine is lighting up Louisville this morning, but the calm will not last long. Warm spring air is building across the Ohio Valley, and meteorologists are now tracking a stronger storm system expected to arrive by Wednesday.
According to the National Weather Service in Louisville, temperatures will climb to around 74°F today under sunny skies. Light southwest winds increase through the morning, occasionally gusting near 21 mph. The air already feels more like mid-spring than early March across Jefferson County.
Clouds increase tonight as humidity slowly builds across Kentucky and southern Indiana. Temperatures remain mild, holding near 61°F, which keeps roads dry for evening travel across I-64, I-65, and I-71.
Showers begin developing Tuesday as moisture continues streaming north into the Ohio Valley. High temperatures reach about 77°F, adding energy to the atmosphere and setting the stage for stronger storms later.
The most active weather arrives Tuesday night into Wednesday. Meteorologists expect numerous showers and thunderstorms, with rainfall totals between 0.5 and 1 inch possible across the Louisville metro.
By Wednesday afternoon, steady rain and thunderstorms may impact commuters and travelers across Jefferson County and southern Indiana communities like New Albany and Clarksville. Some storms could produce gusty winds near 30 mph, along with brief downpours that reduce visibility on major highways.
Drivers should prepare for wet pavement and slower travel on elevated bridges and interstates. Allow extra time and keep headlights on during heavier rain bursts.
Behind the storm system, cooler air quickly settles into the Ohio Valley. Sunshine returns Thursday, but temperatures drop sharply to around 51°F, reminding residents that early spring can still bring fast weather swings.
Temperatures rebound by Friday into the low 60s, and longer-range signals suggest another stretch of warmer spring weather may develop heading toward the second half of March.
Spring break travel is ramping up nationwide through April, so drivers crossing Kentucky and Indiana interstates should monitor weather conditions closely this week.
