JIM Ill believe it if the 00z's hold strong

5-7am

If 15 to 1 I'd b more than 1 or 2 inches added to the RGEM totals depending on how much. Like I'm under 5 to 6 inch area so wouldn't that b 7.5 to 9?

what do these maps mean exactly I see the numbers increased pretty well inland. It's vertical velocity right? But what does it mean for the storm.

Bernie saying Nassau and Suffolk a solid 3-6" storm with no surprise if people report 7-8" there in localized spots.

Yea that's basically what my snow map says. I don't think I'll be changing it. In my opinion, it takes into consideration my concerns while also accounting for over performance. Its a blend of the hi Res and global models basically

It seems like this storm is particularly difficult to nail down. You guys have been deciphering models and studying it for over a week now. One model run it's good, the next it's bad. I've got a headache just trying to follow along. I appreciate the time and effort you all put into it.

Agree GreyBeard, that's why I've been trying to use them less. My snow map will stay final. If it busts low so be it. I have my reasons.

Jman simply stated vertical velocity is one way to measure how rapidly air rises due to things like pressure falls, or movement of air due to baroclinic zones, frontogenesis etc.  Simply stated the faster the rise the harder the precip rates. On this map the more negative the number the stronger the upward vertical motion, the more positive the more downward the vertical motion, or subsidence you get.  So if you live anywhere where the blue is on this image you likely will not be snowing.  This is also a good map to look at to find the best totals during over running events where frontogenesis and baroclinically driven upward motion enhancements can occur.

thanks glad I'm nowhere near blue.

They need to issue more watches and advisories

lol, ive actually seen longer lists. what i was always curios if one area has more than one advisory warning etc. which do they choose to display and how do they choose?

Was very busy at work today and just getting caught up on the 18z runs. Right now my head is spinning. Two things Peak my interest 1 the rgem and the 2 eps 3" mean for nyc. Also the UKie has never wavered through this event. So I'm hopeful but still cautious and don't know what to make of this. Hopefully we'll all have a nice surprise tomorrow

JMan my weenie buddy. right now 3-6" for me is a stretch and I'm 25+ miles east of NYC. RGEM is good inside 24 hours, but 6-9" NW of NYC.........I don't know about that. I hope so though.

Anyone look at the HRRR? I thought that it is usually good inside of 24

As long as you can support your argument with valid points, that's all that matters. If you're right, you're right. If not, learn from it. It's a win-win. Some of the public might be mad, but nobody's perfect. Great point of view, Frank!!

Bastardi actually had a FABULOUS post yesterday about something similar; I'll see if I can find it.

That's what I was trying to say earlier responding to Armando's post. If you draw a straight line from the advisories in east/central Virginia through the western advisories in Mass., it should lead to advisories west of NYC to westchester rockland border. No?

Lee just called it a Suffolk County special. It's been a while since I heard that. I shed a tear

Yes, it looks good. To me it all depends on the type of precip rates that get into our area. As long as the air is saturated and the dry air doesn't win out, people even further north and west could get into the action.

He ALWAYS sticks to his guns. You can learn a lot from that man.

What time does 21z SREF come out?

almost every weather station from nick to lonnie to lee has same snow map they are going for 4 to 8 in suffolk county to coastal nj and coastal connecticut .then 2 to 4 inches for nyc nassau county and connecticut

New RPM. Has been east and suddenly has now shifted west.

Bernie Rayno also had a great line in his video this morning. It was something to the tune of how professional forecasters are scared and essentially scrutinized for straying from guidance with something they believe even if they have no support at the time, and how it's killing the industry. So true.
