DCA briefly dipped to 79F early this AM, so the 80s streak is over at 3 straight nights. But it's oppressive out. DCA is 88/76 at 10am while in Tenley we are at 89/79 for a HI of 104F. It's 10 am folks!!
90F officially at midnight at DCA is absolutely obscene. This is some of the most intense nighttime warmth I've experienced, especially given the high of only 98F.
