December 9th-10th Forecast Map(s) Cut-Off Coastal Storm

[quote="Frank_Wx"]Update:

Morning model runs are consistent to what I said last night. Expect an awful day tomorrow with heavy rain and high winds. Due to saturated grounds, flash flooding is possible in flood prone areas as well as possible power outages from uprooted trees. Snow is not the story with this storm. It's the wind.[/quote]


Frank, are you in the flood zone where you live? I'm not far from you and have 2 sump pumps and a french drain. I hope we weather the rain okay.

Its so hard to believe it will be all rain, its so damn cold here in the Bronx only 27, Frank give me some credit lol, I called the winds and the issue with uprooted trees before you lol

Yet again, Jman, could you post the EURO snow map when precip FINALLY ends lmao sh!t's cray lmfao

Cranford is prone to flooding but I'm in a safe area. Hopefully it works out for you, I'm sure you'll be fine.

I'm not sure posting a bunch of model images that show high winds is the same thing as forecasting. Winds have high bust potential because if the precip is not heavy enough you won't see those higher gusts come to fruition at the surface. That's why you can't forecast them far in advance like you can for precipitation

850's crash after midnight Tuesday. CCB sets up and you probably get decent accumulation 

Warm for the city, cold enough just west though surface is warm

Should be interesting to see where it sets up

I think the column is going to stay right around freezing west of the Delaware river because of the very heavy precip, as well as a strong ageostrophic component to the low level flow working to dam the cold air. The only period of rain may be from mid-morning through mid-afternoon. I think everything else is snow.

Mid afternoon sounds a little too optimistic for me, but anything is possible with a coastal storm. I would agree if it showed signs of deepening at our latitude.

Somewhere between NEPA and just west of the city. City may get into it for a brief period

So you see the rain snow line more of a west east dividing line as opposed to the normal north south? If that's the case that would be similar to February 26 2010 at least in that aspect.

This will be an interesting 48 hours to see how it all evolves.

It doesn't look like the temperatures are going to make it to their predicted highs today. Just something else to ponder as the low level cold doesn't budge. Ice skating in the HV may be an issue.

In my opinion, CP, yes.

First off...happy birthday my friend 

Second, yes...I feel it would be more West to east. You may start as snow before changing to rain

Oh snap!! Happy birthday buddy!

I second that notion. Almost 2:00 here in Nassau county LI and breeze off the ocean and only 31 degrees. That's 5 degrees less than forecast at what should be our warmest part of the day. DOES THIS MEAN ANYTHING REGARDING THE EVENTUAL TRACK/SETUP??

Just hoping against hope here

Thanks Frank and RB

It's been Fascinating watching you guys analyze this upcoming event, monstrosity, coming up. Nothing's easy so far this season.

Slap from Frank damn lol, yes I was jk, I did say LOL, I know you are the man and yes forecast is what you do best. But I did say this was a concern from the beginning so my "guess" was right,is that better : ) And I know that its difficult, depends on the mixing down etc, but with very heavy rain or bursts of precip I think those higher gusts to 60mph are def not out of the question, but will it be everywhere no of course not. To me I am nearing a nowcast frame of mind, rb I will post but not sure what good it will do.

Unfortunately, probably not Snow. Even though the surface is cold, the lower levels of the atmosphere will slowly but steadily warm as the easterlies persist. Then, once the low starts getting more developed and closer, they will warm rapidly.

Look at that spin its coming!

That's just awesome, no two ways about it. How often do you get to see a definable mid-latitude cyclone booking it westward and NOT be linked to something tropical???

I know right rb, it looked so cool to me I had to post it. Gonna watch it every so often to see it evolve. Looks like its getting its act together, may come in stronger, but who knows at this pt. Although things seem pretty in tune with Franks forecast.

Its a shame theres no strong arctic high in place to block it just a nudge more offshore and more cold air injected this could have been a 2' storm for many. The reality is its 90% rain with a chance of some snow showers or squalls on the backend for 95, immediate coast probably nothing.

Without a doubt Tom.

I probably won't get above 33-34 this whole event but because of the mid level warming I probably see two inches or less of snow through this whole event. Only if this backend thing works out will I see anymore IMO.

It's so cold it feels like there could be snow! brrrrr still in the 20's here

This thing moving NW Will it make a loop??

Hey
The storm looks like it wants to slam directly into North Carolina. WHAT GIVES? Currently 32 and north/northeast winds and snow flurries here in Nassau County LI.

FWIW 18z NAM came in further east at H7 with the closed low compared to 12z, and now has it centered just off the NJ coast. 850 0c line reflects this too. SREFs are still a torch for everybody through sunset on Wednesday before 850s start crashing. I don't think I've ever seen the SREFs be so much different from the NAM this close to an event before. Gonna be interesting to see which model suite verifies closer.
