PM Update: Cool Air Reinforcements Arrive
Mostly sunny, below-average temperatures on Friday
Plenty of late-summer sunshine has led to fairly warm temperatures running a few degrees above average in many locations today, though highs in the upper 70s and low 80s are still about as good as it gets. A reinforcing shot of cool air is moving into the area as a cold front passes by this afternoon. Tonight should be quite cool again, and tomorrow's temperatures will be lower than recent days.
Tonight: Some clouds may move in off the ocean overnight, especially south of D.C., so expect variably cloudy conditions depending on location. Readings should bottom out right around 50 in the coolest suburbs while remaining closer to 60 in the city and where clouds are more numerous. Winds will be light from the north and northeast.
Tomorrow: After some morning cloudiness, the end of the work week will be cool and mostly sunny. High temperatures should top out around 70 in the north and west while hitting the low 70s in D.C. and to the south or east.

Its 29 degrees on Mt. Washington right now.

While the relatively high (for overnight period) winds of 10-15mph will make it quite difficult, I wouldn't be entirely shocked if a few of the outer NW suburbs drop to 49 or 48. However, conditions tonight are far from ideal -- you'd want clear skies and light winds to really bottom out temperatures -- so I'd say there's a less than 25% of this happening; but it's still possible!

Fall issue of the Sterling Reporter has a good quick read on the June 4th severe weather outbreak on page 3:

D.C. below 60 tonight? Could it be?

Sterling--I think it's a given. After all, the suburbs are looking to drop past 50.
1025 hPA right now in McLean. That's the highest pressure reading I've seen in quite some time, and we may very well get higher before it recedes.
