The surface low basically tracks over the Mid-Atlantic. I can not see all those heavy rains displaced as far North as what some models would have you believe. This is the warm season.

The only mechanisms for broad-scale ascent are tilted north to coincide over upstate NY. The best PVA, mid-level fgn, and upper divergence are all up there... at least on the GFS. It's hard to overcome all that with a surface wave.

its not even that dry, it's just a lot more scattered with heavier totals.

The system over the middle of the country phases on the latest GFS run, and rides further north as a result. The ridge over you is pumped up a little more and sends the heaviest rain further north. Look at the 500mb chart. The upper low is quite vigorous over the southern Plains-it generated that hundreds-mile long squall line in TX last night and has been vigorous over N TX/OK/AR today. It makes sense that it might try to cut north as it interacts with another S/W over the central Plains.

you can see what's happening here, models are now picking up on the stronger Atlantic ridge, stalling the front further north-sure we'll get some rains, but they will be showery at best and the big rains are going to be up in upstate NY, CNE and NNE.  Seasonal trend of models going drier as we close in on a particular event continues.

Ehh, the flip side of that this time of year is the severe threat might be better and storms might pop up where models don't show it now (happened to me a few times this month, including the last 3 days). Watch the SPC outlooks to see how that might play out (I've definitely learned to refresh that site and check Mesoanalysis since moving down here). 

 

The usual caveat is Long Island, where onshore winds ruin whatever synoptic setup. The more westerly the boundary layer winds can be, the better.

You want a 60 hour moderate to heavy rain event to morph into a 15 minute thunderstorm? No thanks.

Currently partly cloudy and 65 degrees with a strong possibility of a Rangers loss.

Oy vey, at MSG. :(

 

Look at it this way, at least MSG will still be around next season, vs the Islanders having to become a Brooklyn team, and the Rangers making it this far in 2015, and the Finals last year. They played a hell of a series.
