Today is going to be downright unpleasant and tomorrow even worse. A big high pressure system off the Mid-Atlantic coast is pulling hot and humid air into the region. Look for highs this afternoon in the mid 90s in the city and lower 90s in the suburbs. The heat and humidity have set off a heat advisory as well as an air quality alert. In response to the heat the city has opened cooling centers and the Salvation Army is opening their community centers to help people keep cool.

The humidity will slowly increase through tomorrow night. This means an uncomfortable night tonight as temperatures will only fall to the upper 70s in the city. Tomorrow will probably not be as warm as today but with the added humidity the heat index will be higher. Triathletes and Siren Music Fest goers beware! Drink plenty of water, wear light-colored, loose-fitting clothing and try to avoid the sun if possible are chief among may ways to beat the heat.

A cold front approaching Saturday may kick off a few showers late in the afternoon tomorrow. Cooler weather is expected on Sunday after the front's passage. Expect a high only in the upper 80s. Thunderstorms are likely Sunday night.
