Memphis is starting Saturday near 72 degrees under clear skies, but the comfortable morning will quickly give way to a sunny afternoon near 95. There is no rain in the forecast, though an ozone alert adds a health concern to an otherwise classic late-August day. The heat is only beginning to build, with upper 90s expected for much of next week.
Sunny Saturday Comes With An Ozone Warning
The National Weather Service says Shelby County is under a Code Orange ozone forecast through 5:30 p.m. Saturday. The advisory covers Memphis and nearby parts of Arkansas and Mississippi, with the Shelby County Health Department warning that ozone levels may be unhealthy for sensitive groups.
Active children and adults, along with people who have asthma or other respiratory conditions, should limit prolonged outdoor exertion during the afternoon. Morning errands and exercise will offer the more manageable window before sunshine and rising temperatures put the most strain on outdoor plans.
Sunday Pushes Toward 100 Degrees
Saturday night should stay mostly clear, with temperatures settling near 73 and light east winds. Sunday will be hotter, reaching about 98 degrees with heat index values as high as 101, while a light south-southeast breeze offers little relief.
The new weekend forecast is a notable step up from Friday's outlook, which called for a high near 92; Hoodline's earlier report covered that brief dip before the weekend surge.
Mostly Dry Heat Holds Through Next Week
Monday is expected to reach 97 degrees, followed by highs near 98 Tuesday and 99 Wednesday through Friday. Overnight lows will remain in the upper 70s, so Memphis will get little meaningful relief after sunset.
Rain chances stay very low through most of the week, with only a slight chance of showers and thunderstorms arriving Friday afternoon. The National Weather Service also expects humidity to increase around midweek, which could push heat index values closer to 105 and make the prolonged dry spell feel more oppressive.
For now, the practical forecast is simple: plan strenuous outdoor work early, drink plenty of water and take regular breaks in shade or air conditioning. Anyone especially sensitive to ozone or heat should keep Saturday afternoon activities brief and monitor updates from the National Weather Service.
