POST: 12PM EDT FEB 10,2012 

I am sticking close to my first call idea with a developing storm that will be just strong enough to produce heavy snow for areas along I 95 except away from the immediate shoreline.


One thing that I have come around to accept is that the 500mb trough bringing the cold air in will NOT be as positive as yesterday's models showed it would be.  Yes, it's still positive but it will NOT be enough to cause the storm to go due ENE away from the coast.  Development with this storm will be key to who will get over 2-3" in my last call maps below.  However, I do see enough lift for interior NJ, LI, CT, MA to see a quick accumulation for many.  

500 MB GFS MAP

THIS IS A RUNDOWN OF THE EVENT.

The cold air will be delayed some allowing for mostly rain to fall from Baltimore to Philadelphia on south and east.  From there the cold air will drain towards the storm as it begins to intensify.  Expect heavy snow to break out right near a coastal front that will setup over coastal NJ, DE, and Long Island.  Which by mid morning will pull north and focus the heaviest snows over Boston and Providence.  

There is still plenty of moisture left via the GFS going into Sunday afternoon also for a few spots over the higher terrain to see a quick coating.

SO HERE IS MY FINAL CALL:
