The storm already has delivered its first surprise: Snow amounts overnight were expected to be light -- but not quite this light. In and around Philadelphia they have been negligible.
Light snow and freezing rain continues to fall on glazed roads and cars in much of rhe region, but the heavier precipitation is staying farther north toward Reading and Allentown.
We're still anticipating a lull before the stronger storm approaches with heavier precipitation later this afternoon or this evening.
That's the source of all the concern and the reason winter-storm warnings remain for Chester, Montgomery and Bucks Counties, and a watch for Philadelphia and South Jersey.
