Yeah. Verbatim it just about makes it to my location and stops.

Just based off the 00Z NAM for what it may or may not be worth I'm good with my 6-10" early call. We'll see how it plays out.

If that is indeed the track they take, I need to see rest of 00Z guidance before I lean that way, then 100% we're going over to sleet for a large part of this sub forum. You can't avoid mid level warming with 700/850 lows to Lake Erie. This is where we were at at 9:00 this morning. The 12Z guidance and 18Z guidance for the most part backed away from that, except for the CMC stuff. Let's see what the rest of the 00Z guidance has to say.

When I went through it it was just cold. In this situation the cold will be extreme. Can't imagine no heat in this.

Went through that once. Never again I hope.

Out of our area but check out this sounding from RDU area. Warm nose is rather deep and freezing layer is very shallow just a little above the deck at about 1000 mb. level. Some locations down that way are going to get crushed with ZR and be without power for days in bitter cold. Bad scene.

More recon, this time over the Gulf going into the models.

I can give you a few candidates I'd lay money on.

I wonder why?

Journalism is DEAD. Died a long time ago.

Got up to 45 here. Not sure what the forecast was. I wasn't paying attention. I like that my heating system got a 1 day reprieve.

You don't see a map like this every Winter.

Wouldn't you think they would want it the other way? I don't know, I would think they would lose the public's confidence by going down more so than going up. I won't beat it to death.

Man oh man the cold just keeps unloading out of Canada over the next 10 days or so and MAYBE into early February. The actual temperatures and departure from normal maps are pretty astounding honestly.

Check out the rapid ice buildup on Lake Erie over the last 10 days or so. https://www.meteo.psu.edu/ewall/PSUGOES_NE/loop60v.html

Same. Very aggressive. Especially SNJ. Again, they know what they are doing.

Wow. Pretty aggressive along the south shore of LI back to EWR. Me personally I would have gone lower to start and then raise if needed tomorrow and/or Saturday. I just think you set yourself up for egg on face starting at the upper ranges. Just my 2 cents. They clearly know what they are doing. Any subtle shift north and those amounts will under perform.

I'm more conservatively going with 6-10 at this point along the I78 and I80 Corridor. Allowing for the mid level warming to be a little more aggressive than modeled. Although the latest EURO has me leaning to much less mixing north of 80 and west of 287. Still significant uncertainty on exactly how the 2ndary unfolds. QPF very consistent at around 1" on all guidance. Only if something totally unexpected happened with the 2ndary would that go up markedly. Use 1" of QPF and the ratio of your choosing to to convert to snowfall and allow for sleet to mix where you believe it will mix in.

Read this morning the UKIE got an upgrade yesterday and in terms of skill scores it is 2nd. to EURO.

All guidance has been consistent for a few days now on .9 to 1.2" of QPF. A few ticks up / down at times but in general have been locked in on around 1" of liquid.

It has better evolution and track for the secondary. Kind of on its own right now with that solution.

Thanks @SACRUS for your map postings last 24 hours or so. I'm on the road today so nice to pull over and scroll through here to get a sense of what the models are doing even if I don't have time to look at upper level stuff etc. I have to say the RDPS and ICON secondary placement is not bad. Just have to get it going fast enough to halt the warming mid levels. If it gets going fast enough it could keep the immediate interior mostly snow. Either way 6-8 / 6-10 seems like a good call based on the early guidance so far this morning. Higher end of range with some upside potential if secondary cooperates.

Temperatures across Alberta Province of Canada this morning are running -20 to -40F. Temperatures either side of Lake Winnipeg in Manitoba are -20 to -25F. Impressive cold!

That 10 for immediate NYC region could be generous.

Yep and I would not ignore it.
