A blizzard Warning is in effect through at least through Midnight for most of the northwestern half of the state. Winds of up to 40-50mph in gusts along with falling and blowing and drifiting snow will lead to near zero visibilities throughout the rest of the day into tonight. Accumulations of 2-4 inches of snow are possible in the blizzard warning area. Surrounding that is a Winter Weather Advisory which is also in effect until Midnight. Snow accumulations there will be in the 1-2 inch range with a few higher amounts possible.
