The thing is, if it doesn't snow 8" here you (or anybody) can't go into meltdown mode.
Even saying 2-4" is reasonable seems like you're going out on a limb. Rain/slush, or even whiff, is just as reasonable. We're 4-5 days out.
My forecast: precipitation likely on Saturday. Some slushy snow accumulation is possible. Details to be ironed out.
