Nws grids thru 0z Saturday 

Always interesting to see how the individual offices are thinking. The sharp drop offs at various county lines is kinda funny. Albany much more bullish than Buf, Bgm, and Btv.

Where do you get these awesome maps from?

Looks like they're thinking some lake snows with a WNW wind based on those maps.

Wxbell pretty awesome site. 

Looks like there little bit in the grids for late tomorrow afternoon/evening ahead of the main storm. Buffalo forecasting more than Bgm.

They have you right near the sweet spot! Where system qpf meets LES qpf maxima. Looks good to me. Now we hope we don’t get a rogue warm layer.

The point n click shows the difference in the grids between sw Oswego (buf) and nw Onondaga (bgm)

So I take umbrage with the Euro. It’s south of the other models which means the warm air tongue isn’t in play which means a colder overall solution .4 at KBUF but 4”? 10-1? Toss. It would equate with ratios of 15-1 to 7”. 

How do you toss a rip and read 10:1 ratio???  I get that you think ratios might be higher deeper in the cold air, but a 10:1 ratio map is ALWAYS going to be wrong for some...no matter what an independent model outputs for qpf....it's just essentially a first guesstimate...

And I honestly think ratios don't do any better than 12:1 no matter where you are within the airmass...the DGZ is shallow with weak lift (omega)....

Kuchera avg is 17.5:1 at buf so that's almost certainly too high. Maybe somewhere in the middle but probably closer to 10:1 like LEK said.
