Weather Forecast – NBC4 Washington

Very hot temperatures will keep the Washington, DC, area sweating through the weekend, and Sunday will be the hottest day of this heat wave, Storm Team4 says.

The good news for Friday and Saturday: Humidity levels are a little lower, providing a touch of relief. Your outdoor plans will be safe from rain, but protect yourself from the heat by staying hydrated, seeking shade and taking breaks.

Highs will still soar into the 90° to 96° range amid sunny skies Friday afternoon.

On Saturday, temperatures will be a couple of degrees warmer, and the heat index will be near 100°.

The heat index on Sunday is set to near 105° as humidity picks up again. Expect highs in the upper 90s; there’s a 50-50 chance that DC could record its first 100th day since 2016, Storm Team4 says.

There’s a 20% chance of a pop-up shower or storm, but most of the DC area will stay dry until Monday. The workweek will begin with a 60% chance for rain and some thunderstorms. It will also be mostly cloudy and humid.

Heat Safety Tips

Intense heat can quickly become dangerous. Keep an eye on people vulnerable groups including newborns, infants, children and the elderly.

“Heat is one of the leading weather-related killers in the United States, resulting in hundreds of fatalities each year,” the National Weather Service says.

To stay safe in the heat, avoid strenuous outdoor activities, or move them to the cooler morning hours. Stay hydrated, opting for water and sports drinks over sugary beverages. Take shade breaks. Know the signs of heat-related illness.

Never leave a pet or kids alone in a parked car. Temperatures in cars can rise to lethal levels within minutes, even with the windows cracked, according to KidsandCars.org.

Wearing loose, light-colored clothing can also help you stay cool.
