The head of the National Weather Service has urged that "people should pay attention" to the developing snowstorm that is threatening the Washington, D.C., region and beyond. Speaking at a press briefing at NOAA's Center for Weather and Climate Prediction in College Park, Md., Dr. Louis Uccelini advised that, "if people haven't taken action and they're driving on (the I-95 corridor) on Saturday, they're at risk."
For those who might harbor some skepticism over the accuracy of the predictions for the upcoming storm, Uccelini explained that he was struck by the consistency of the forecasts.

"I don't remember seeing four of five modeling systems having this much consistency," from seven days to one day out, he said.
The latest NWS forecast predicts a 73 percent chance that more than 18 inches of snow will fall on the Washington area, beginning Friday evening and continuing through Saturday. That would be the city's biggest snowstorm in almost 100 years and the third largest in its history, although some outlier models suggest the total could even reach 30 inches, which would be a record. The weather service has upgraded existing blizzard watches for the DC area to blizzard warnings, and has issued blizzard watches for New Jersey and the fringes of the New York City area.
