Louisville woke early Thursday, August 20, to light rain and a damp start, but the weather is expected to turn warmer and more unsettled through the day. The high should reach 84, with breaks of sunshine between showers and thunderstorms.
Showers are most likely early, then chances dip through midday before isolated storms become possible again late afternoon. Winds should be light south-southwest before the front, then shift from southwest to north-northeast, while rainfall totals could reach 2 to 3 or more inches west of I-65 and south of I-64 and 1 to 2 inches farther east.
Storm Risk Builds Around The Cold Front
The National Weather Service forecast calls for numerous showers and thunderstorms with the approaching cold front Thursday night. But the agency’s broader forecast discussion says a cold front crossing the region tonight could bring a more numerous round of showers and thunderstorms, especially west of I-65.
Forecasters identify damaging winds and localized flash flooding as the main concerns if storms strengthen or repeatedly track over the same areas. Conditions can vary quickly across the region, so move indoors when thunder is audible and never drive through a flooded roadway.
Sunny Breaks Arrive Friday, Cooler Air Sunday
Friday looks mostly sunny and warmer, with temperatures in the low to mid 80s and dew points in the upper 60s. Saturday should initially be dry, with highs in the mid to upper 80s, though a slight chance of afternoon showers and thunderstorms could interrupt outdoor plans.
Sunday brings a mostly dry break, with highs in the low 80s and drier air. Cooler low-80s temperatures continue Monday with low precipitation chances, before temperatures warm from the low 80s to the upper 80s by Wednesday, when another slight storm chance returns after 2 p.m.
