Reston, VA

How hot will it be the weekend of July 22/NWS


That’s the word of the weekend for Reston and the rest of the Washington, D.C. area.

Some of the hottest air of the season and possibly of the last several years will hit us beginning today and lasting through at least Monday.

Temperatures will feel like they are around 100 today — and the heat index reads more like 105  — or more — for Saturday and Sunday.

“You should expect excessive heat with temperatures in the upper 90s with heat indices at or above 105°F (Fahrenheit). The hottest days appear to be Saturday, July 23 and Sunday, July 24 when heat indices could approach 110°F,” says the Fairfax County Department of Emergency Management.”

The hot weather system is part of a “heat dome” stretching over much of the country. Read more about the forecast from the Capital Weather Gang.

Meanwhile, there is a Code Orange air alert for Friday. That means the air will be unhealthy for sensitive groups, including children, people with asthma or heart disease and the elderly. Those groups should avoid strenuous activity outdoors.
