The bust-high potential is REAL for NYC metro/southern New England. It's gonna surprise a lot of people come the evening rush. What a Face

From Craig Allen - see wth have I been harping on with this the CAD SIG !! Its gonna win bigly this winter

.
Craig:

Getting a little concerned / nervous. I sure wish I had a chance to get acclimated with a few snow showers rather than hitting me up with an all out storm for the first one. Sheesh.

Scott I think when precipitation first starts there may be a mix or even plain rain along Coastal sections and even into the city but as the precipitation picks up in intensity it looks as if the column cools and the rain snow line drops 50 miles south of New York City. the latest hrrr shows that very nicely. can't post on my phone I don't think we have to worry about low-level warm air making it in to change over to rain I think we have to worry about the 700mb warm nose that seemef to bust down south let's hope that warm nose never makes it up here

This thing looks like its ramping up - any chance of thunder snow? These rates are going to be aggressive!!

I know we're not supposed to model hug, but they all look so good. From 10" on the NAM 3k to 16" on the RGEM. Pardon my ignorance on the following question, but will this be a basic 10:1 storm or will ratios slide one way or the other?

We shall see. Its going to boil down to location location location. As I said above... dew points are still in good position to drop temps under heavier banding, but it has to happen soon.

Upton better get their act together in a hurry.

by **heehaw453** on Thu Nov 15, 2018 12:33 pm

Snow falling heavily right now. All roads covered and temp is 27.5. Clearly it's colder than what has been modeled at the surface IMBY. If we can hang on to the cold at mid-levels, then watch out. I noticed Mt Holly has gone over to warnings for some of the northern counties. Won't jinx it, but i love what i see so far!

by **SoulSingMG** on Thu Nov 15, 2018 12:35 pm

AND JUST AS I POSTED THAT LAST MESSAGE!!!

Winter Storm Warning now for Westchester, Advisory issued for the city!

First Wintry Event - 11/15 to 11/16 - Page 8 9ae1b010

by **weatherwatchermom** on Thu Nov 15, 2018 12:35 pm

the flakes just started flying here!

by **Grselig** on Thu Nov 15, 2018 12:36 pm

Warnings have been issued in Eastern Passaic and Morristown NJ. 5-7 inches plus ice. My concern is that driving around many trees still have leaves on them. I remember Halloween storm from years ago. Large scale power outages. Trees today are much more bare, but with ice, it could be an issue. Hope not.
