Louisville starts Tuesday with clear skies and temperatures in the low 60s, but the city is headed for a near-record-feeling 91-degree afternoon. The brief summer encore comes with sunshine, dry weather and southwest winds before storms move in Wednesday and fall finally shows up by the weekend.
Heat Peaks Tuesday
Tuesday will stay sunny from morning through late afternoon, with southwest winds increasing to 5 to 12 mph and no rain expected. The National Weather Service Louisville office is forecasting a high near 91, followed by a mostly clear night with a low around 69, according to the National Weather Service.
Storms Roll In Wednesday
Rain chances jump Wednesday, with a slight chance of showers and thunderstorms late in the morning before storms become more likely through the afternoon. Rainfall totals may vary, with generally 0.5 to 1 inch near southern Indiana and under 0.5 inch south of the Ohio River; higher localized amounts are possible. Stronger storms could produce gusty winds.
Precipitation chances reach 75% Wednesday night. Thursday stays unsettled too, with spotty showers or a few storms possible, mostly cloudy skies and a high near 83.
Fall Finally Arrives Friday
A cold front brings a chance of early rain Friday, followed by partly sunny skies and a much cooler high near 68. Northwest winds will increase to 12 to 17 mph, and temperatures will fall to around 42 Friday night.
Saturday looks sunny but chilly, with a high near 60 and a low around 37 Saturday night. The broader forecast points to a growing chance of the season's first frost in colder areas Saturday night into Sunday, while Louisville itself is expected to stay just above freezing.
A Sharper Turn Than Last Week's Forecast
The latest outlook is a substantive update from Hoodline's earlier forecast, which had focused on a warmer, drier stretch and a later rain threat. The newer pattern brings the wet weather into the middle of the week before delivering a sunny Sunday near 68 and a mostly sunny Monday near 72, as detailed in Hoodline's earlier report.
No watches, warnings or advisories are listed for the area Tuesday morning. For outdoor plans, Tuesday is the cleanest window; after that, keep an umbrella handy, secure loose items before the storms and prepare for a distinctly colder weekend.
