Sunday’s temperatures should stay around 90, with a heat index closer to 100, under mostly sunny skies.

But 7News First Alert Meteorologist Jordan Evans said a stray shower or storm during the afternoon is possible. Any storms should end by midnight and clouds will clear by sunrise, with low temperatures in the middle 70s.

D.C. Mayor Muriel Bowser has activated a Heat Alert for the District until 8 a.m. Wednesday. The District said the alert was extended until July 1 because temperatures are expected to feel like 95 degrees during the day and 80 degrees overnight.

“Mostly sunny and then turning hot and humid,” Evans said. “Not much of a breeze out there.”

Storms are possible Sunday between 4 p.m. and 6 p.m.

Temperatures slowly come down to the 70 overnight with decreasing clouds.

Afternoon showers and storms are expected Monday as well, with some likely becoming strong or severe with gusty winds and hail. Widespread severe weather is not expected at this time, Evans said, and temperatures are expected to be around 90 degrees.

The D.C. region can expect a cold front will be on the way Tuesday, with more shower and thunderstorm chances. Some may be strong to severe, with gusty winds.

Behind the cold front, temperatures will fall a few degrees Wednesday, with a lot of sunshine in the forecast.
