MJO off the charts Phase 8 = BN Temps and Stormy possiblities EC







Phase 1 and 2 for March are good - 2 is excellent = SPRING DENIED for a few days to maybe week !!!

18Z Euro
Trying to analyze surface map.  There are some intriguing ingredients.  

Surface Low starting to intensify off OBX. Banana H in the mid-west and stout 50/50 blocking up the Atlantic. Also weak CAD bleeding down from New England.

Then looking at the 500mb you have a ridge developing just to the west of the Rockies. 

You'd have me with this if we had the 1035 H over Quebec fully extending that banana H. But we rely on phasing to suck in the n/s.  I guess I'm warming up a bit to this...

[sroc4]

Morning.  Quick update.  Biggest difference between GFS and Euro basically comes down to how they are handling the western ridge.

Below is the 500mb height anomaly maps representing 2pmMonday. Notice the difference in the strength of the oranges in the S west between GFS and Euro.  Also notice the little circle of Orange on the euro vs GFS does not have it over Montana.  What this tell me is that by Monday 2pm euro is building a western ridge and the GFS is not.  And start to pay attention to the blue circled in the eastern third of the CONUS.  This is our mean trough.





Fast forward approx 12hrs to 2am Tuesday.  Now take notice how the GFS is just beginning to develop some orange in the northern tear of the CONUS whereas, the euro is now trying to connect the warm colors in the SW and N.  Again this signifies a much more robust ridge to our west.  The direct consequence of the more robust ridge is the blues much darker and deeper into the S&E




Going back to 2pm Monday maps lets look at the vorticity maps at 500mb.  The result of a weaker vs stronger ridge out west means the difference between no phasing and weaker S energy with flatter 500mb heights along the EC, and losing some of the S energy OTS VS phasing, stronger S energy that raises heights along the EC drawing that energy up the coast.  





Looking at the surface map the differences between no phasing and phasing at 500mb is a much weaker slp exiting the EC much further S headed ENE to NE (GFS) because of the progressive flow and positive to neutral trough tilt VS a much stronger slp exiting the EC further N with a trajectory to the NE to NNE because its being pulled in by the phased system that has a negative tilted trough.  




So again to summarize I think both GFS and Euro have the N Atlantic blocked up indicating eventually there will be a phase.  But currently the GFS has a weaker trough development to the west so the mean trough cannot dig early enough resulting in a phase that ends up being a little late and overall less impactful system.  However, the euro builds a more robust ridge in the west which results in a mean trough that digs earlier phasing the N and S energy early enough to develop a much more robust slp bringing it up the coast as a potent and rapidly deepening system that will be very impactful system one way or another.  Details for the our coverage area is still way up in the air so please for the love of all that is holy do not ask if you think a particular snow map soln can happen for any particular backyards yet.    

Just as a PS if you will, the GFS ensembles supports its operational soln, and the European ensembles supports its operational soln.  As you can see in the images below the GFS ENS have an avg slp between 995-1000mb; whereas, the Euro Avg slp is in the 980's.  





So there is a cross roads still out thee.  FWIW the euro has handles the upper levels for tonight's system over the past 3 days much better than the GFS.  Remember the GFS had a strong system with snow to the coast for tonight just a fw days ago and it moved to the euro sln.  Lets see if the same holds true for this upcoming system and we see the GFS trend towards a stronger western ridge and a more potent phased soln

WE TRACK!!!

[heehaw453]

Euro phasing no margins.  Want to see this phase a few hours earlier say off Southern NJ with run/run consistency.  This part of the process is everything.

edit: it's the part where this thing gets captured and tugged back to coast.

[sroc4]

Moved my post to its own thread

[crippo84]

Super informative thanks a lot.

[heehaw453]

GFS doesn't dig the ULL enough. It's less potent. Subtle yet enormous differences at the surface. I'd want the Euro to dig it even more.  Very muted on this right now.

[nutleyblizzard]

Wake up everybody! The Euro, Ukmet, and CMC came in colder and show a MECS. GFS is slowly coming around as well.

[Frank_Wx]

Let’s move the discussion to the thread Scott started

[sroc4]

I know many are still involved with today, and rightfully so, but just throwing this out here. Possibly one last dance around 22nd-24th as the MJO cycles through phase 1-2 and possibly into the Null phase. The end game perhaps? Long way off and not likely.

The models have been hinting at something along the east coast in that time frame so worth keeping an eye on; But I've been so disappointed with this season that I'm kind of in the I'll believe it when I see it stage of snow grief.

I see that Godzilla on the models next week. But what if it's another tease?

[CPcantmeasuresnow]

We may get 10 inches out of this when it’s done so I’ll take another tease like this. The journey has been torturous though. I’m still not sure where this goes from here. Sitting at 5.6 inches atm.

Actually Doc 5 miles from me has 7 inches.

ORRRRRRR I see that tease on the models next week, but what if its a Godzilla!!!!

G’on get gone! If it is, JMan is buying

Of course it will snow next week, I'll be in Florida.

[dkodgis]

Janet, that looks like the Coconut Lounge.

Will be stopping there on my way to Florida, have to check on the Volcano

Wait why me lol, Nope no way I am going to pretend I heard that theres even something to possibly look at nope no way.

[jmanley32]

Might we be tracking one more around 28th? the runs today were interesting but I am sure if anything were to happen would give the interior snow, doubt the coast has any shot. So many storm systems but none produce, well technically the last one did in fact it blitzed but it was just too warm, had it been really cold I might seen 6-12.

Absolutely that last Nor was a MECS IF - the most important ingredient - had a true arctic air course.

I do remember some years when I had to put plywood against my back garage wall to keep the snow off my crocuses and daffies. The forsythia is coming out here. So are the maple leaves. I am keeping a close eye on my hostas. Last year it was April 15. The year before, May 1. The year before, May 15 when hostas started peeping up out of the ground. If I do the math, and there continues to be a two-week trend, I will see hostas popping out about April 1. We'll see.

Didn't do the math but in 10 years Nov. 1st and winter will be nothing but a memory with sun and highs in the 70s pretty much from oct to may.

[Radz]

Looks like a pretty cool and wet pattern for April?? Just a continuation of our non-winter conditions lol

[dkodgis]

Looks like this Friday is going to be a gully washer.

[Frank_Wx]

The annual closure of the long range thread begins today. We'll be back next Fall!
