Louisville has a greater impact on the United States than you might expect. It’s home to Yum! Brands and UPS, and was the cihildhood home of Muhammed Ali and Diane Sawyer. The city is pretty proud of their history, so remember that next time you hear about the Kentucky Derby or Louisville Sluggers.

At 1058AM, CT, Louisville was reporting a temperature of 82 degrees and mostly cloudy skies. There is a weak trough moving through Kentucky this morning that is producing a band of cumulus from about Jackson, Ohio to Kentucky Lake. There may be a few showers associated with this this afternoon, but they will keep south of Louisville.
A narrow trough over the Great Lakes is the parent of this trough, but the ridge of hot weather that most of the nation is experiencing will force that boundary and any hospitable air back to the northeast. There may be a passing shower on Tuesday as this air mass transition takes place, but by Wednesday, this dome of hot air will take hold and suppress any convective activity. Record highs are possible.

The most interesting part of this forecast for me is that WeatherNation has the same temperatures but a different precipitation forecast than the Weather Service. Take a look at the satellite imagery below, showing that band of clouds south of Louisville.
