UPDATE 8:10 AM Thursday - The "SHARP cut-off" is keeping Delaware out of the heaviest bands of snow, as expected.

UPDATE 11:50 PM Wednesday - I added more model data below with the latest GFS output.

-----------

A major winter storm is coming to the Northeast, but areas East of Delaware, I think, will get hit the hardest.

This is my expectation.

The moisture to watch has been racing out of the Gulf of Mexico and up the coast into New England with a major Nor'easter.

Here's a sneak peek at the latest model data:

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

1 PM Thursday afternoon, February 25, 2010 - North American Mesoscale (NAM) model, based on today's 0z run (7 PM)

NAM is yielding around 1.00 inch of liquid or

10 to 17 inches of snow

By early Friday morning, winds on the NAM model suggest gusts inland around 55 mph and higher along the Shore.


Scattered power outages will continue to be a problem.

There is new emphasis that this snowstorm will linger into Saturday as well.

The NAM model depicts an accumulation phase that comes in 3 distinct stages, namely Thursday, Early Friday Morning - Friday, and Saturday morning.



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

1 PM Thursday afternoon, February 25, 2010 - Global Forecast System (GFS) model, based on today's 0z run (7 PM)
null

GFS is yielding over 1.10 inches of liquid or

11.5 to 23 inches of snow with some mixing to start

By late Thursday afternoon, winds on the GFS model suggest gusts inland around 40 mph and higher along the Shore.





Here's my thinking...

10 to 20 inches of snow will be possible with higher drifts for the Philly Metro and I-95 corridor.

Some mixing, especially early on, is not out of the question.

There is likely to be a SHARP cut-off to where the heavy snow bands form. If you live east of Delaware, you have a better chance of seeing the higher end of that 10 to 20 inch range.

Conversely, if you live between Dover, DE and Georgetown, DE, for example, you should get much less than 10 inches of snow.



Expect blowing and drifting snow, some icing, beach erosion and coastal flooding.

Stay tuned.
