Fourth of July weekend in the D.C. area is bringing hot and sunny weather with a chance of thunderstorms.
Temperatures reached the low 90s Saturday afternoon and the humidity made it feel warmer. Some thunderstorms moved through parts of Maryland in the late afternoon.
The D.C. Department of Homeland Security issued a heat warning for Saturday as the heat index reaches 94 degrees, urging those who can't be inside to find a cooling center.

Fireworks shows could be hard to see from some angles because conditions may be right for a phenomenon called temperature inversion. That is when a layer of warm air in the atmosphere hangs over cooler air on the ground, trapping smoke from fireworks shows.
That made it tricky to see D.C.'s major display last year and in 2016. This year, a light northeast wind is expected, meaning Northern Virginia and areas south of the National Mall could be less affected.
Sunday is forecast to be mostly cloudy but still humid and hot, with highs of 85 to 90. Afternoon thunderstorms are expected for some in the D.C. area.
If you will be spending much time outside, remember to stay hydrated and be generous with the sunscreen.
Next week looks like typical D.C. weather in July: hot and humid, highs in the low 90s and a risk of afternoon storms just about every day.
