Snow forecast getting deeper

Latest computer model guidance sees big-storm potential.

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."

The new model showed a significant bump in snow totals and suggested the possibility of "thunder snow" Wednesday night with snow falling at a rate of one to two inches per hour for several hours.

Stay tuned.
