Have you caught your breath yet ?

The next storm is coming.

When ?

Late Tuesday (toward evening) into most of Wednesday

For the Philly Metro and I-95 corridor...

NAM is yielding roughly 0.65 inches of liquid or

6.5 to 10 inches of snow.



1 PM Wednesday, February 10th, 2010 - Global Forecast System (GFS) Model, taken from the 12z run (7AM)

For the Philly Metro and the I-95 corridor...

GFS is yielding over 1.50 inches of liquid or

16 to 25 inches of snow.


*** Some rain, freezing rain or sleet may mix in as well and could significantly lower these amounts. ***

This is the trend.

Could it change ? Of course.

So what's important ?

I think parents, students, and decision-makers need to prepare mentally for at least a foot to a foot and a half of snow (12 to 18 inches).

Clearly, based on the current data, 1 to 2 feet of snow is not out of the question.

We are still several days out.

The storm data will continue to change.

Updates will follow.
