They have to in case it busts. They will talk about all the ways it could end up busting no matter how the models look. It's been that way ever since the Dec 2000 storm bust when Fishel ended up in the fountain playing the tuba because he guaranteed a big snow storm for Raleigh. Ever since then they and all the other local mets just go with the model that shows the least amount and play it safe instead of really making a forecast. They would rather it end up more than they say than end up less than they say. And then they can say we told you everything that could go wrong to cover their bases.
I'm thinking 2 to 4 inches south of Raleigh and 4 to 6 inches for north of Raleigh. 6 to 8 for north of Wake.
