Snow forecast getting deeper

Computer models have been all over the place on snow totals for the coming storm, but this morning the U.S. North American Model went on tilt.

The most-recent run showed a major snowstorm for the immediate Philadelphia area, and the National Weather Service is considering bumping up the advisories.

Right now, it has a winter-storm watch for Montgomery and Bucks Counties, but it says it is weighing extending it all the way into South Jersey.

In the updated morning discussion. the forecasters acknowledged the new computer guidance and entreated, "Please give us time on this."
