Sunday will be less humid, with cooler temperatures in the mid-80s.

A few isolated storms are possible on Sunday afternoons, but mostly south of the DC area.

Expect mostly sunny skies on Monday, temperatures in the mid-80s and the possibility of individual storms in the afternoon.

Tips for dealing with extreme heat

  • Stay indoors if possible, or find shady or air-conditioned spots.
  • Stop by your neighbors. Young children, the elderly and people with access and functional needs are most at risk.
  • Drink a lot, but don’t drink liquids that contain alcohol, caffeine, or large amounts of sugar.
  • Keep pets indoors. Walk pets early in the morning, give them plenty of water, and don’t leave them in vehicles that can reach dangerous temperatures within 10 minutes. For any animal emergency, including animals left outside in extreme temperatures or in vehicles, call the Humane Rescue Alliance at (202) 723-5730.
  • Wear suitable clothing and sunscreen. Choose light, loose fitting, light colored clothing and wide brimmed hats. Use sunscreen with SPF 15 or higher.
