UPDATE 11:35 PM Tuesday -
1 PM Thursday afternoon, February 25, 2010 - Global Forecast System (GFS) model, based on today's 0z run (7 PM)
Courtesy: NCEP
GFS is yielding nearly 1.0 inch of liquid or
9.5 to 19 inches of snow with some light mixing to start
By Friday, winds on the GFS model suggest gusts inland 45 to 50 mph and higher along the Shore.
The timing of the storm is still on target, although a few lingering snow showers may re-appear into Saturday as well.
--------
A major winter storm is set to hit the Northeast.
The moisture to watch will be racing out of the Gulf of Mexico and up the coast into New England with a major Nor'easter.
Its track is still critical to determine just how much snow makes it to our area, but its effects, no doubt, will be far reaching.
Here's a sneak peek at the latest model data...(not a forecast)...just 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)
Courtesy: NCEP
NAM is yielding over 0.95 inches of liquid or
9.5 to 17 inches of just snow
By Friday, winds on the NAM model suggest gusts inland 45 to 50 mph and higher along the Shore.
For the Philly Metro and I-95 corridor...
Start Time for this event ?
Around 1 AM Thursday morning, February 25th, 2010
Ending Time for this event ? (Confidence here is a bit lower)
Around 9 AM Friday, February 26th, 2010
What does all this mean ?
At a minimum, it means blowing and drifting snow, some icing, beach erosion and coastal flooding.
1 to 2 feet of snow across the Tri-State...with the heaviest toward New York City is still on the table.
For the record, the 18z run (1 PM) of the
GFS model had 18 to 32 inches of snow with heavy sleet mixing in (especially to start) from the same storm for Thursday and Friday.
A wide-range here still equals great uncertainty.
Stay tuned.
