February Medium/Long Range Disco


WinterWxLuvr

Recommended Posts

Hello,

 

As a transplant from the "PA thread" and long time lurker of you folks due to family area's of location (Manassas, Hampstead). Wanted to ask how important is Wednesday's setup, to get us the "unicorn" for the following weekend? I know it would be the best of both worlds to get snow for both, but would it be better to scarifice the snow on Wed, in order for us to get hit better on sat?  Was just wondering if we really needed the low to cut on Wed, in order to set up for Sat?

 

Or if Wed does work farther east, resulting in Snow, would that then change the ball game for Sat?

True that...but (and that's a big BUT) if you're looking for trends AND it looks like other models at that range..then maybe...just maybe.....

 

I've stopped looking at the nam almost completely unless something is inside 72 but more often inside of 48. I waste enough time as it is. However, the nam is really good with h5 through 48 imo. That's my favorite set of panels when looking for little shifts that mean a lot in sensible outcomes.

I was teasing. I'm feelin this vort. Euro saw it, lost it, and brought it back. It's a good sign. And a reasonable progression after the front clears. Best winter week on tap for tracking in a long time. 

the midweek vort is not far behind it on 84 hr NAM so it's gunna' be flat when it comes by us which is what we want

Going off memory here since the Ewall reanalysis hasn't updated for Dec 2013 yet, but isn't the midweek pattern somewhat similar to the pattern that produced the Dec 8th storm?  Gradient-type pattern.  Certainly mixy looking with the SE ridge battling the eastern Canada PV.  The pattern for the unicorn storm does look pretty blah.  Certainly not screaming MECS/HECS.  

 

 

It is a decent pattern, but it certainly doesn't support a gigantic storm for the coastal plain...someplace like MRB could get clocked though...I'd favor an inland runner or maybe even up the APPS...I don't think we'd see something coming from the gulf go to the OV or lakes in that pattern...I might start planning my roadtrip to Hagerstown ;)

Worst week to write an article about winter weather chances in a long time. 

I thought yesterday's was the toughest outlook of the year.   I probably be wishy washy about ptype for the 8-9 storm as I'm not sold on the track, not against it, I just don't know and wish there was better blocking a little farther south to make sure we gt a nice southern track.   I don't mind these kinds of write-ups as we're not close enough to any of the events to be completely sure of the outcome though I'd bet against me getting much snow with the Wed event.

The 2010 blizzards are what got me into this hobby, so I don't recall - how far out did the models start agreeing that something big was afoot on those?

 

Ridiculous leads. Like d10+. But the current pattern is exponentially more hostile. 2010 had classic blocking and predictable track at unusually long leads. We have none of that this time.

I figured, but the curiosity was killing me.  Thanks!

It's a happy place where weenies waste hard earned cash every year endlessly chasing ghosts. It stinks that SV has different euro data like analogs and such. I'll probably get both next year because I have issues. 

This is a great place to waste my weenie time. I can watch the experts chase ghosts and learn along the way! ;-)

It's a perfect dance of hp to the north, confluence, and good vort track. So much can go wrong but I think we end up with some snow out of the period. Weird seeing such a signal with a sketchy pattern. 

im sure zwyts knows but Im sure we have had 1 or 2 double digit snowstorms in crappy patterns

We just need to get it under 180 hours...that's still sketchy time, but at least it's well under truncation.   Once we get it to 144, it's Adventure Time.

this is how you do it. Killer antecedent airmass and a friendly wall to the north. Even being progressive in nature the airmass leading in is legit. A tight track would still yield good snows.
