In short, not much in terms of snow, if you are not in the Northwest US. We have some snow leading up to the weekend, mainly across the northwest US and Northern Rocky Mountains, then this weekend starting mainly later Saturday and through Sunday a COLD looking storm system drops in across the Cascades and Northern Rocky Mountains with significant snowfall potential, 2 to 4 feet for the Cascades, significant to 1+ feet for the northern Rocky Mountains, and 1/2+ feet for southern Idaho.
