D.C. emergency declared as dangerous heat wave moves in

D.C. issued an extended heat emergency through Friday and activated cooling centers as a stifling heat wave settles in along the East Coast.

The big picture: A heat dome is building in intensity across the Ohio Valley and lower Great Lakes. It is forecast to shift east-northeastward this week, and potentially peak at record intensity at this time of year for New England.

The latest: The National Weather Service forecasts highs in Washington at between 93°F to 99°F through Saturday, with the hottest temperatures arriving later this week.

• It's possible that some locations in the Mid-Atlantic and Northeast will see temperatures climb to or above 100°F late this week, given the computer model guidance, which has trended warmer in recent days.
• D.C. hasn't hit 100°F since 2016.
