    DC: Building Heat, Humidity Into Midweek

    Heat and humidity will continue to build around Washington, D.C., into the middle of this week, but the return of cooler air is on the horizon.

    The humid air will remain in place through midweek as temperatures also soar.

    Wednesday is shaping up to be the hottest day of the week with a high in the lower 90s. AccuWeather RealFeel® temperatures will top 100 degrees for several hours during the afternoon.

    The combination of the warmth and humidity will create challenges and hazards for those who must engage in strenuous labor and those with respiratory issues.

    An afternoon thunderstorm or two will dot the area through Tuesday, especially from the city and points to the north and west.

    The daylight hours of Wednesday should also stay rain-free before a cold front returns a shower or thunderstorm at night and on Thursday and sweeps away the surge of warmth and humidity.

    The timing of the front through Washington, D.C., may put the city at risk for stronger thunderstorms later Thursday.

    A fresh shot of cooler and less humid air from Canada in the front's wake will lead to a pleasant Friday.
