DC area sizzles from the heat on Sunday with little relief in sight

It may be the hottest day of the year as daytime highs neared 100 and humidity keeps climbing. Here’s what you need to know on this sizzling Sunday in the D.C. region.

  • Regional Heat Advisory in effect from 11 a.m. to 8 p.m. on Sunday.
  • Heat index around 105 on Sunday.
  • Stray storms are possible.
  • If you are out in the heat, take precautions or seek shelter.

Even as we roll into the evening – and hopefully a little relief – it will take some time to come off the highs that had the whole area sweltering today. As of 6 p.m. Sunday evening, the high temperature at Reagan National Airport was 97 degrees with a heat index of 104.

Other highs recorded were 96 in Charlottesville, Va., 97 in Baltimore, Md., and 94 in Hagerstown, Md.

We’re not alone in trudging through this. According to the National Oceanographic and Atmospheric Administration (NOAA), 22% of people living in the United States were experiencing dangerous or extreme heat on Sunday.

NOAA also says to expect the dangerous heat to continue well into the coming work week.

The humidity rose throughout the day and, while there have been a handful of stray showers, it won’t be enough to beat back the heat. National Weather Service forecasts that Monday’s heat indexes will be between 100-108.

For Sunday night, we have a 20% chance for isolated showers and thunderstorms in
the evening. If we’re lucky, lows tonight may dip into the (comparatively arctic) upper 70s.

Heat advisories will remain in effect for the entire region until 8 p.m. Sunday night. Try to stay inside during the daytime when the heat index will hover around 105 for most of the region.

If you have any strenuous activities scheduled for the day, please consider doing them in the late evening when temperatures are lower.

Dr. Gupta told WTOP  people need to be aware of the dangers extreme heat presents.

“Oh, very dangerous, because people underestimate the damage it [heat] can cause. And as a physician, I know that it is bad for good health,” Gupta said while taking a break in the shade.

Also, remember to hydrate yourself regularly — even when you don’t think you need it. Dehydration, heat exhaustion and heat stroke have a reputation for sneaking up, so stay safe with a few simple precautions.
