Incredibly, the high today in Washington, D.C. only managed 74 degrees, tying (with 2004) the coolest high temperature for the date on record dating back to 1872. We warm up some Wednesday, likely up to near 80, but that’s still below average. An approaching front could set off some showers and storms.

Through Tonight: Skies are mostly cloudy, and there may be some spotty drizzle this evening. With a light breeze from the south and the blanketing effect of the clouds, temperatures are close to steady, only falling back to the upper 60s in most spots.

Tomorrow (Wednesday): More sunshine than today and with a stronger push of southerly winds (around 10 mph), we should pass 80 – highs 80-84. It’s humid, and there’s enough moisture around to support the chance of mostly afternoon showers and possibly thunderstorms (40 percent chance).

Today’s cool weather in perspective: Today’s high of 74 (the coolest on record for the date) stands in the sharpest possible contrast to this date in 1918, when D.C.’s record high of 106 was set. And last year on this date, D.C. tied its record high minimum temperature, dropping to only 78 degrees, four degrees warmer than today’s high!
