5:00 PM update

Hold the phone. The 18z American models just came in colder than the 12z models. This is due to a very slight shift south of the lower level features of the storm. This is why this forecast is very difficult in regards to precip type (sleet or snow at this point) and snow accumulations.

Models though have been very consistent in dropping about 1 - 1.5 inches of liquid precip. The surface temp looks plenty cold enough. I'm feeling very confident that the predominating precip type will either be sleet or snow. Really tough to guess on the snow amts.
