Louisville is waking to clear skies and temperatures near 52 degrees Tuesday, but the calm start is the opening act for a sharp warmup. Sunshine will push the afternoon high to about 82 degrees, with nearly calm winds and no rain in the forecast. It is a fine day for outdoor plans before the weather turns decidedly less cooperative later this week.

The National Weather Service forecast calls for mostly clear conditions Tuesday night and a low around 59 degrees. A little patchy fog may develop in low-lying areas early, but visibility should otherwise stay favorable across the Louisville area.

Warm Weather Peaks Thursday

Wednesday will be mostly sunny with a high near 88 degrees as southerly winds return. Thursday looks warmer still, reaching about 91 degrees under mostly sunny skies, with a mild overnight low around 71. In other words, September is squeezing in one last summer-style run before the front arrives.

Rain Arrives Friday And Lingers Through Sunday

Showers could begin after 8 a.m. Friday, when the high is expected to reach 85 degrees and the chance of rain rises to about 50%. Rain showers are likely Friday night and Saturday, with Saturday staying cloudy and much cooler near 71 degrees. Sunday brings another chance of showers and a high near 71, while a few showers could linger into early Monday.

The timing is wetter than an earlier Hoodline forecast, which had the rain arriving sooner and tapering by Friday night. The latest outlook instead points to the most unsettled stretch from Friday through the weekend, so outdoor events and travel plans may need a backup option.

No Advisories Are In Effect

No watches, warnings or advisories are currently listed for Louisville. Tuesday through Thursday offer the best window for sunshine and outdoor activities, while Friday through Sunday call for umbrellas, flexible plans and extra time on wet roads.
