Summer’s hottest weekend arrives

The hottest weekend of the summer is here, and no rain is in the forecast as the heat index is expected to be near 100 or above on Saturday and Sunday.

“Between now and Monday, it’s all about the sizzle,” said Storm Team4 meteorologist Chuck Bell, describing the weather. “It will be nothing but high temperatures and sunshine.”

With severe heat in the forecast, D.C. will continue its ongoing heat emergency plan through Monday and open cooling centers across the city. The heat emergency plan went into effect earlier on Friday.

The city also extended outdoor pool hours for Friday through Sunday. Specific pools will be open from 10 a.m. to 8 p.m.



High temperatures in the D.C. region peaked in the low to mid 90s on Friday, with slightly less humidity than Thursday. Reagan and Dulles airports near D.C. both reported a high temperature of 93, while downtown Baltimore reached 96.

The average temperature for this time of year is 90.

“High pressure, associated with the heat dome that has been baking the Southern Plains all week, is expanding into the Mid-Atlantic,” Bell said.

“This will suppress rain chances for the next few days, but leave us with temperatures approaching 100 by Saturday and Sunday afternoons,” Bell said.

Temperatures through Friday night are expected to in the 70s.

While no formal heat advisory has been issued for Friday, heat will, as Bell said, approach 100 in parts of the area, with only the possibility of an isolated storm on Sunday.
