Damaging Ice and Moderate Snow in Two Storms

I think it's well known by now that we are going to have horrible ice storm from northern Texas into western Kentucky the next 36 hours. Some areas will get over an inch of ice accumulation which means extended power outages and poor travel. On the other hand, the snow is going to be only in the moderate category with accumulations up to 6 inches. Travel through the area shown on the maps you are now seeing everywhere will be very poor.

The storm that comes into northern California and brings a rare snowstorm to northern California and southwestern Oregon will zip across the southern Rockies to produce another storm late in the weekend. We will see widespread 20:1 to 30:1 snows through the Plains into the Great Lakes and a nasty ice storm for the Appalachians into New York. Shown below is the GFS p-type for the Sunday storms. Some areas may get a few inches of snow before the change to ice occurs.

Following that storm is yet another storm for late next week into the weekend. That storm has some potential to bring snow to areas of the Northeast that miss out on the Sunday snow. NAO still trying to going negative which if blocking occurs, means the storm is heading to the coast. The Euro seems too warm with the storm at least to me while the GFS looks colder and more what I envision happening.
