Through this winter one of the major impacts that has significantly impacted snow fall totals is the development of mesoscale snow banding within the precipitation shield. The impact of such banding has produced staggering snowfall gradients throughout the region and has created significant impacts on many locations this winter.

The surface low that has brought a near historic 20.9 inches of snow in Central Park and over a foot in many locations throughout the northern Mid Atlantic is slowly weakening and exiting to the east.

The latest 12Z NAM is out and boy does it deliver a heck of a snow storm!

The entire northern Mid Atlantic is digging out of 6 to 24 inches of snow that feel over much of the region the past 24 hours as the blizzard that impacted the region exits into the Atlantic.

A weak disturbance is moving through the Philadelphia and New York City metropolitan areas this morning with a few scattered snow flurries. No accumulation is expected, however the snow showers will likely put a nice touch to the cold conditions in place right now. Let’s be honest, what’s the point of it being cold [...]

Last night I commented on my concerns about cold air holding on and the potential for more ice than what guidance was suggesting.

A cold front with an arctic air mass on the verge of driving into the New York City and Philadelphia metropolitan areas is slowly pushing through central Pennsylvania this morning.
