Memphis, Tenn. – Oppressive heat will grip the Mid-South on Wednesday. Temperatures are set to climb into the low 90s across the region. The humidity will make conditions feel much worse for residents in Memphis and Shelby County. The heat index is expected to reach a sweltering 101 degrees, creating dangerous outdoor conditions.
According to the National Weather Service in Memphis, the intense heat will build throughout the day. A slight 20 percent chance of showers and thunderstorms is possible after 1 p.m. Wednesday. Any storm activity could bring brief relief but also lightning risks. A south-southwest wind around 10 to 15 mph will offer little comfort from the heat. Residents should take precautions, especially during the hottest parts of the afternoon.
The weather pattern shifts slightly for the Juneteenth holiday on Thursday. While the high temperature will dip to a more manageable 88 degrees, the chance for thunderstorms increases to 40 percent. Those with outdoor celebrations planned should monitor weather updates closely and have a backup plan in case storms develop. Conditions are expected to dry out by Thursday night, leading into a mostly clear and warm evening.
Looking ahead to the weekend, a significant warming trend takes hold. Friday will be mostly sunny with a high of 91 degrees. The sun and heat continue Saturday and Sunday, with high temperatures reaching 94 and 95 degrees, respectively. The sunny, dry pattern offers a break from storm chances but elevates the need for heat safety. The extended outlook shows storm possibilities returning by Monday.
