The storm will follow the stationary front between two areas of HIGH pressure....

so we know it will snow the question is how much and will it stick ?

If you are N & W of I-95 like Philly burbs, Lehigh Valley and even the hills of Northern New Castle County you could see a light snowfall by daybreak. The skies did clear quickly tonight under low dew points and little or no wind and clear skies. That is changing quickly as the temps will level off and and clouds lower and thicken the next few hours
