Snowstorm Placement (Dec 17-31)

BLOG SONG...HOW DEEP IS YOUR LOW (BEE GEES)

 

 

I know your eyes in the morning glow
I feel you touch me in the "falling snow"
And the moment that you wander far from me
I wanna feel you in my "models" again

And you come to me on a "winter breeze"
Keep me warm in your love and then softly leave
And it's me you need to show

Chorus:
How deep is your "LOW"
I really need to learn
Cause were living in a world of models
Breaking us down
When they all should let us be
We belong to you and me

 

 

We have a good deal of confidence regarding snowstorms for the second half of December the tougher part is finding the exact track for each one. Weather is all teleconnected and each variable play off another.

VARIABLES FOR DEC 17-31

 

--How much cold is cold (December Cold vs. Arctic Cold)

--Blocking Potential (-NAO...how deep is your low)

--Big storm...little storm concept

--BYOC...Bring your own cold (to the storm)

--Bomber Time (do you explode the storm off the coast)

 

BLOCKING PATTERN.... (-NAO RUNS HOW LOW?)

Looking over the NAO above I see a moderate to HIGH risk of a nor'easter but the placement is going to be so so crucial come the next two storm chances.  The block is there but not a FULL block with a -1 on the index vs. -3 during Sandy and -2 the nor'easter after that.

 

So with a -1 NAO index you get maybe more of a Northern Mid Atlantic and New England storm depending on where the storm makes an exit off the coast next week.

 

Yes the true Arctic Cold Air is delayed behind the NAO and it may catch up as the NAO is heading to a more neutral run. This is not a bad thing it's a model's nightmare as they try and find not only where or even if the Northern and Southern Jet will phase but when they will meet.

 

This will make for a series of model runs the next 7 days of off the coast storm and out to sea to an inland I-95 storm of rain.

The Winter Dance is all about the Northern Jet & Southern Jet having that special dance at the party full of dips and spins and more.

This is a dynamic storm and has some pretty decent potential IF the track plays out a certain way come next Tuesday and Wednesday.

THE EURO JUST IN... WOW

MY THINKING AT THIS POINT...

 

This is getting interesting for sure as  the models are starting to see the push to the coast. This is worth watching simply because the BEACH EROSION AND NOR"EASTER impact could be as potent as the snow itself.

Thanks for the update, Rob. Looking at the "winter dance" I have decided that the snow line needs to waltz all the way to the beach...LOL! What?! Is that asking so much? ;)

Weather in song! That's been a while. Usually we're playing cards. Either way, both are effective in getting the point across, and I love it!

Hi Rob:

Do you think Syracuse would get this? If snow, do you have any idea how much? Also if this is a snow event would we see the largest impact. After passing would Styracuse have lake effecr snow after?

Some of the cards are in our hand but still waiting on the placement. Way early but it's nice to have something to discuss. Now all we need is Hair, Oaktrain and Doc to make this a full fledged event.

FYI December 2009 storm...when it was 5 days out the models were all over the place oh I remember that very very well. I think the Euro and GFS are better than they were 3 years ago when it comes to bigger storms

I wouldn't worry about the details 7 days away at all. There's no way at model could get that right at this point. We need to wait until after the 16-17 to figure this one out in afraid.

Bob alls it's going to take is a high pressure to pop up in Quebec and its game on. It happens quite often. For example dec 2009 and dec 2010 lol.

Marcus the Euro is a big storm, but it's warm as all heck. Rain all the way to the Poconos into Central NY before a chageover up that way and then just cold on the backend down here with maybe soem flurries at the end, but no snow verbatim anywhere on the Euro.

Euro staying consistent 2 runs in a row is nice.

Mother Nature owes us this one.

Well the euro was certainly interesting. Hits the BM sub 975.

Consistently showing a storm now on most models. So now it's just a matter of time of where it's gonna be. Gonna be fun for the next week. Ill give it til Sunday-Monday timeframe to start getting nailed down.

Philly currently has the 11th longest snow drought since 1887, and if we don't get any snow by Christmas, we will have the 3rd longest snowless streak.

Rob: Excellent blog and graphics. What time for the next model runs? Does the weather look ok for travel on Mon and Tues am from the Philly suburbs to southern DE? I realize its four days away, but trying to plan some things.

John...

Thanks...yea I agree to low of an NAO and we get the supressed infamous Southern Slider issues. Good for our friends in NC that love snow so they would get the Golden Shovel in that pattern

Great blog Rob...

You know, I remember when the NAO got so negative, that the Deep South got all the big snows and up here, we didn't see anything. Pretty much a suppressed storm track. Looks like the big Nor'east will be too warm for next based on the 12z GFS. This run does show another system that would impact the Carolinas by Christmas Eve. But now we are seeing some very interesting tracks and finally a very interesting pattern to wrap up 2012..
