The summer solstice brought not only the longest day of sunshine to the Washington area, but also temperatures in the high 90s that put the region under a two-day heat advisory.

As temperatures soared to a high of 97 degrees Wednesday and a projected 99 on Thursday, the National Weather Service placed the region under the advisory until 10 p.m. Thursday. The region also is under a Code Orange air quality alert — unhealthy for sensitive groups.
