Just How Cold? Take a Guess...
Overnight, temperatures will drop to their lowest levels of the season. How low will they go? Here are my predictions for our three official observing sites:
Reagan National Airport (DCA): 14
Dulles International Airport (IAD): 8
Baltimore Washington International Airport (BWI): 9
What do you think? And, in the morning, let us know how cold it got at your location.
