That's bc you bought the hype of colder aloft= automatic high ratios. The winds were 40knt plus throughout the snowgrowth. Don't care how cold it is, you dont get good dendrites with that kind of wind. Different set up this time.

Agreed 700 MB looks to b in the right area , and only think back to dec around Philly Deleware and in SNJ

They all went 20 to 1 due to great lift .

If Upton saying 20 to 1 I'm gona believe them

If I recall correctly, though, some major stations such as LGA and JFK had ratios between 15 and 20:1 during the January 3 storm. 

 

It's often the better CCB banding that has the best ratios. Areas further west never got into that banding. The banding has the best LIFT in the snowgrowth zone, which helps for ratios. Of course, cold temperatures help as well, but without sufficient lifting in the snowgrowth zone, it's hard to consistently get good ratios.

Good point, nyc was also just around -5c - -7c for the first 1/2 of the storm at 700mb. By 3am the dendrites were beautiful.

Vort is stronger and a bit faster on the NAM. PV is slightly west of 6z, which is not as good.

 

Edit: Changes negligible through 12.

 

 

In a splitting PV scenario, you want the further south piece to be further west. That can buckle the flow a bit, shift the trough axis a bit, and "tug" the storm a bit closer to the coast. 

 

As long as the north piece moves to the 50/50 region, we're good.

I bought nothing . Never thought we were ey ting high ratios during that storm. It's so rare to get ratios more than 15-1 in these parts . .(when not in a heavy band)

Yeah, ISP had 11.2 of snow off .61 liquid equiv.

Great point.  We saw snow here (Poughkeepsie) for 24 hours with temperatures in the single digits, and ended up with a total of around 6" of snow with a liquid equivalent of around 0.50".
