WLKY: First extended heat wave of summer expected in Kentucky’s first week of July, with dangerous humidity

WLKY reported on Monday that the first extended heat wave of summer is expected to develop in the Louisville area and across the region during the first week of July, bringing “dangerously hot, humid” conditions, according to its weekly weather planner.

The station’s update, published June 29, frames the period as the start of Kentucky’s early-summer stretch of elevated temperatures and humidity, which can increase the risk of heat stress for people who spend time outdoors or who lack access to cooling.

WLKY said it is tracking the timing and intensity of the heat over the coming days, with the planning focus centered on early July rather than a single day. The report emphasizes that humidity is a key factor, because it can make the air feel hotter and reduce how effectively the body cools itself through sweating.

The weather planner also points local viewers toward staying aware of rapidly changing conditions during the week, when heat can persist even into the evening hours. For households, the practical challenge is managing comfort and safety as daytime highs and overnight warmth combine to keep temperatures elevated.

Kentucky communities often see multiple groups affected during extended heat events, including people working outdoors, residents in housing without reliable air conditioning, and older adults and children who may be more vulnerable to heat illness. WLKY’s framing centers on the elevated health risk associated with high humidity, not just daytime temperature readings.

As the start of the first week of July approaches, WLKY said it will continue monitoring the developing pattern. Viewers are directed to watch for updates to the forecast, including changes that can affect how long the heat remains and when any relief may arrive.
