Memphis fog should fade quickly Thursday morning, but the easy start will give way to serious summer heat. Temperatures are expected to climb from the low 70s early to about 95 degrees this afternoon, with the heat index reaching around 101.

Patchy fog is expected before 8 a.m., followed by mostly sunny skies and a light north wind. Rain chances remain low at roughly 13%, and no watches, warnings or advisories are listed in the current forecast from the National Weather Service in Memphis.

Foggy Start, Sunny Afternoon

Thursday night should be mostly clear, with temperatures dropping to about 72 degrees and northeast winds between 5 and 10 mph. The combination of sunshine and lingering summer humidity means outdoor plans may feel far hotter during the afternoon than the morning forecast suggests.

A Brief Friday Dip Before Weekend Heat

Friday offers a modest break, with mostly sunny skies and a high near 92 degrees before temperatures rebound. Saturday is expected to reach 94, while Sunday could hit 97 under sunny skies.

Mostly Dry Heat Builds Into Next Week

The warming trend continues Monday through Wednesday, with highs near 96, 97 and 98 degrees, respectively. Rain chances stay low through the period, making this a mostly dry stretch for Memphis as summer refuses to leave quietly.

Plan Around The Afternoon Peak

Morning hours will be the more comfortable window for exercise, errands and outdoor work, while afternoon activities will call for water, shade and regular breaks. The forecast remains calm rather than stormy, but the rising heat index is a reminder that clear skies can still pack a punch.
