Sun-Mon Feb 9-10 Inverted Storm Potential

Yeah but I think more times than not when we see them in the 3-6 day range...they're a placeholder.  Sometimes we end up with bonafide storms instead...this time it seems like what we may be trending to is energy spaced just too far apart. 

 

There's still a little glimmer with a later system IMO...so we'll see.   It's down to either that first one clipping us, or a later system dropping in.  The trough thing is going out the window it appears.

 

This is what I wrote 2 days ago.

  Wonder if we see that southern s/w scoot offshore fast enough to allow the follow up one to dig and amplify.

One of two scenarios needs to take place in order for a more significant system:

 

1)  A downstream block needs to force the wave to curl in on its self (basically ...break)

 

2)  An upstream ridge amplitude forces the down stream mass field to collapse, and any conveniently timed S/W gets a steroid injection and goes nutty (Feb 2006) 

 

...Neither of which appears to want to take place; thus the wave(s) maintain an open ...like way open translation.  

 

Personally I rather like the inverted trough/Norlun esque appearance there, as having 20 hours of wind max translating along the latitude of DAY to ISP is typically observed during llv convergence scenarios.

I think this is a scenario in which the northern stream energy actually trends stronger and digging deeper into the southern US.  I think some GOM moisture gets injected into the northern stream shortwave and with the baroclinic zone pushing northwest due to the southern stream shortwave moisture gets pushed northwestward.  H7 moisture field is quite expansive for the Northeastern US and Oh Valley.  I think a large swath of 3-6" is possible from CHI eastward towards PA and then into the SNE region.  NAM is trending stronger and digging deeper with the northern stream shortwave.  Need to watch this carefully.

NAM tossing in the towel on system one for the Euro idea of a system passing through at 75-80 hours.  Plenty of time for that to evolve a bit into something better. 

 

Punt the first system and the trough idea.

 

Ive been watching the later system, the northern stream energy can create its own snowstorm for SNE, if that energy can dig an H5 low south of SNE, and south of Long Island, NY.  NAM is mishandling something, just what I don't know yet.

Looks pretty meager if anything at the moment. Wow, did this crap the bed over the last 4 days....but that's what happens sometimes with this flow.

From a modeling standpoint yes it did, but from an expectations standpoint I hope for everyone here nothing crapped out.

The 06z NAM was a comical run, highly unlikely, but shows what my general thought would have been had the lead s/w gotten ahead enough.

Yeah I'm speaking from a modeling standpoint as it's not like an OTS storm..it's literally no storm.  I still think we may have to watch for some lighter snows.

Yeah it is pretty amazing how it went from a huge southern juiced system to almost nothing. The southern storm idea was only like 120 hours out...for us, it was a bit further and very possible we'd miss, but seeing what amounts to a weak sauce wave off South Carolina is pretty amazing considering the agreement on something way more significant 4 days ago.

Yup.  The overriding pattern this year has been progressive so seeing amped up solutions that far in advance does not excite me.  Same with the VD system.  I'd rather see it over Cleveland right now.

 

Some of those SREF members deserve a Keyshawn Johnson "C'mon man!"

 

I suppose we should watch that s/w for lighter snows Sunday night.

:lmao:   One looked like a full-blown noreaster.

 

What we do know is that we have a s/w that will traverse the area on Sunday.  If we can generate enough lift we should be able to eek out some snsh during the day.  T-1".
