The mercury dipped to 60 degrees at Reagan National Airport this morning, something it hasn’t done in August since 2004.

We have to go back to August 7 and 8, 2004 to find cooler readings, when DCA’s lows were 58 and 59, respectively.

While chilly by recent standards, today’s low at DCA was notably warmer  than the record of 51 set in 1963.  The 60-degree reading tied for 3rd lowest since 1929.

As brisk it was here in D.C., it was much cooler  to our west and north.
