Discussion

A powerful storm will slam into California later today and bring substantial rains to much of the state over the next 24-36 hours or so with as much as half a foot of rainfall in some areas. This strong storm will then cross the nation over the weekend with copious amounts of moisture and it will reach the Mid-Atlantic region by later Sunday. At the same time, very cold Arctic air will slowly drop southward into the Mid-Atlantic region and the result could be a substantial snowstorm on Monday across much of Pennsylvania and southeastern New York State with a foot of snow on the table. There will also be some icing included with this storm in this region, but the greatest chance for significant icing will likely occur just to the south of the PA/MD border, but even in this area there will be accumulating snows. More bitter cold air will follow the early week storm in the Mid-Atlantic region and throughout much of the eastern U.S.
