Addition: Dr. Cliff Mass has some thoughts here.
And, you should see some of the comments on various Facebook pages, "Idiots all." "Pay them only when they were accurate!", etc., etc. Below, I talked about the unique way this storm seemed to wrap around the District and how that is simply not forecastable.
Now, look at the actual (as sensed by NOAA weather satellite) snow accumulation from this storm.

accumulations associated with darker blue colors.
Tornado warnings by themselves save 1,000 to 2,000 lives a year. The warnings for Hurricane Sandy saved thousands of lives. Planes no longer crash in wind shear. I fully get that yesterday's miss caused problems and money. But, while weather forecasting and storm warnings are rapidly improving, they remain and inexact science.
