High temps settle over Louisville for the rest of the week. Here's what you need to know

Louisville residents are advised to plan outdoor activities carefully this week as a persistent summer heat wave settles in the region.

According to a Monday morning forecast from the National Weather Service in Louisville, the city may not see a high temperature below 94 degrees through Sunday. The hottest day of the week could be Friday, with a high near 99 degrees.

Breaks from the heat may be limited, as there are only a few chances for isolated rain showers and thunderstorms, mainly on Monday night and Tuesday afternoon. Though the heat wave will be prolonged, it should not be "overly intense," the weather service office in Louisville said.

"Those most likely to be impacted are people working outdoors, those without access to air conditioning, and other vulnerable populations," the weather service said in a statement Monday.

A heat advisory is already in effect for much of the Cincinnati metro area and is expected to remain active until 8 p.m. Friday.
