Record High 104 Friday

Friday shattered the record high temperature for July 29 by five degrees, reaching 104.

Thankfully, as the temperature was rising, the humidity was dropping, keeping the heat index at least a little bit in check.

A heat advisory was issued from 11 a.m. to 9 p.m. Friday. By noon, the heat index in D.C. was 105. A hyperthermia alert was put in effect before 9:30 a.m. when the heat index reached 96 degrees.

A weather front to the north is sparking some strong thunderstorms Friday evening, but those should be gone by about dawn.

Saturday will see highs in the mid-90s and a heat index around 100. There will be the potential for scattered and isolated storms that could produce frequent lightning, as well as a lot of rain and wind.

Expect highs in the mid-90s again Sunday, but less humidity.

While the highs shouldn't threaten the triple-digit mark again in the coming week, they'll likely remain about the high-80s averages for this time of year.
