Wouldn't weaker help in scooting along quicker?

I dunno really. I'm not sold the first low is a giant player in the second low as others are. I think the long wave trough orientation is more important. I guess the first low does impact the broadness of the main trough to some degree? They're connected but not sure there's a silver bullet with the first low. Need the trough to look better when it's passing our hood.

From what I've seen (and I could be wrong), the proximity of the southern low assists in elongation the front side of the Midwest trough. Which inhibits organized precip chances. The tug on the isobars seems apparent on the latest couple cycles.

Not sure how we avoid it at this point. I just want to get norlun'd for hours and not care someone 3 miles away gets melty -SN.

Maybe early Feb. 2009 would be something similar. That was the system that produced localized 8-10 amounts in southeastern PA in Lancaster county while areas only 10 miles away got literally nothing. 

What a fun night that was local met said flurries ending in an hour then it snowed 1-2" from 7PM to 2AM we got 7.3" here in Media and even a couple of lightning strikes!!  Lancaster PA got 6" band of snow went from Lancaster PA to the Coast... the band north to south was like 35 miles wide.

 

Philly International got 10" and Pitman NJ South Central picked up 14" the forecast was for snow ending LOL

 

Bensalem PA Bucks County Had partly cloudy skies with a flurry and moon shine and that is 32 miles to my north northeast here in Media what an interesting night that was.  next morning was quite cold and Windy!

Yeah that makes sense. I haven't really followed super close run to run. It does sort of create a 'weakness' for the base of the main/somewhat disjointed trough to move toward rather than having it wrap up or something if you had more upstream ridging. It's always seemed a bit back-weighted with the best vorticity/winds though and has generally ended up pretty broad even in the good runs. A closed 500 mb low passing over Chicago isn't our best look.   It's looked more like a severe weather setup if it was not winter than a winter storm setup to me most of the time. The bulk of the goods in the 500mb trough are pretty flat at the base and mostly focused there and behind. You're running out of land and the timing is off but the look on the Euro around 72 is a GA to Carolina high risk in a Nina in April at 18z. ;)

Two things I have learned about inverted troughs in Feb 4th 2009:

 

1: I liken trying to find what will happen with an inverted trough compared to finding a needle in a haystack.

 

2: I liken figuring out what an inverted trough will do compared to a lake effect snow band.  It's here..... No wait it's over here...no now it's here.

 

In other words whoever gets 6"+ from the trough is not much different than hitting a sizeable lottery win!
