Sunday, July 19, 2026, started steamy in Nashville, with clear, muggy skies and mid-morning temperatures hovering near 75°F. Forecasters expect a classic summer sauna, with highs around 93°F and heat-index readings that could top 100°F. Scattered afternoon showers and thunderstorms are likely, and any stronger storm late day into the evening could bring brief heavy downpours, localized flash flooding and gusty winds. After sunset, temperatures dip only into the mid-70s, with additional storm chances persisting overnight.
Afternoon Storms And Flash Flood Risk
Showers and thunderstorms become increasingly likely Sunday afternoon, with the National Weather Service putting the chance of measurable rain near 70 percent and hourly probabilities rising into the 50–70 percent range by mid to late afternoon. Many neighborhoods may only see light daytime totals of less than a tenth of an inch, but slow-moving storms this evening could dump a quarter to a half inch in spots and trigger brief urban and small-stream flooding. This forecast and flood guidance come from NWS Nashville.
Hot Through Early Week
The heat does not back off after Sunday. Highs are expected to stay in the low 90s on Monday and climb toward the mid-90s on Tuesday, when heat-index values may reach or exceed 105–106°F. Tuesday is on track to be the hottest day of this stretch, and a Heat Advisory could be issued with later updates. Vulnerable residents and outdoor workers should plan ahead, take frequent breaks and limit strenuous activity during the hottest part of the day. Slightly drier and a bit cooler air is expected to arrive by Wednesday, although overnight lows will remain warm in the low to mid-70s.
Cooling Centers, Shelters And Resources
Metro Nashville has activated heat patrols and expanded cooling support for people without reliable air conditioning, and shelters and day centers are open for relief from the heat. For the latest list of services and outreach options, see Metro Nashville OEM. Room In The Inn’s Hope U Day Center at 705 Drexel Street and Nashville Rescue Mission at 639 Lafayette Street are among the locations offering extra access, water and cooling during extreme heat.
Plan For Commute And Outdoor Plans
Pop-up storms this afternoon and evening can cut visibility and quickly clog surface streets, so the toughest window for travel is likely between about 3 and 8 p.m. Give yourself extra time if you need to be on the road. Keep water handy, shift workouts or yard work to the morning hours if possible, and never drive through standing water, no matter how shallow it looks. Hoodline will update readers if watches or warnings are issued.
