MASSIVE WINTER STORM ACROSS EAST USA THIS WEEKEND. HEAVY SNOW ACCUMULATION POSSIBLE

METD ALERT DEPT
ALERT FOR HEAVY SNOW

The 300 mb forecast shows that there will be a heavy activity that
will begin this midnight Eastern time in usa. The trough with 100
knots+ value is currently setting over eastern states of usa like
maryland,virginia,New york, and the surrounding states. This is
expected to bring heavy rains which will convert to snow as the
temperatures are below the freezing point. The 100 knot trough will
activate the system. As Day <saturday> falls another powerful system
will move north which will have 140 knots jets that will hit right
around saturday evening to afternoon hours. This will be the real
show. The 72 accumulated precipitaion from this hour shows that it
would be about 5-7" accumulation of snow in areas of
Maryland,Baltimore,Washington,Newyork etc. bUT NATURAL,LOW LEVEL JETS
OF 60 KNOTTS WILL BE THERE AT THE WARNED AREAS.These incredible
precipitation totals can be attributed to the NAM predicting the
coastal storm to "bomb out", or drop 12 mb in 12 hours, with the
minimum central pressure dipping to around 975 mb by Saturday night!
The resulting intense pressure gradient on the backside of the storm
will cause blizzard conditions with gusts to near 50 mph.THE COASTAL
AREAS IN THESE WARNED AREAS WILL HAVE HEAVY RAINS AS THERE IS WARM AIR
FROM COASTAL AREAS.

NWS has released Winter warnings for these areas activating from
Friday Midnight to sunday morning. I am sure this can be a historic
one and people will enjoy a lot.

storm as well and I am expecting some good phtotos from here as well.
