People are frustrated because we look at the models in aggregate. Nobody seriously expected the para to be right, and most people didn't seriously expect the 3k to be right either. There wasn't a single model I saw at 00Z last night which showed <2" of snow+sleet at DCA. For most people, that was the last guidance they saw. It was 2"+ of sleet (NAMs), or 2"+ of snow (everything else) at DCA. Yet we seem to have gotten the combo of mostly sleet like the NAMs said, but a much faster storm leading to lower accumulations. Maybe we get lucky tonight? But right now guidance looks like it may be a bust for DC across the board.
