Bust of the Century January 26-27 2015 model suites and discussions

I think if anyone's in for the bust, it might be Philly. They were always on the edge and the NWS bit hard on them getting a good snow event. This looks to end up somewhere between Boxing Day and 2/8/13 with the heavy banding. If that excludes Philly, Mt. Holly's going to have egg on their face. Models have consistently today been backing down there big time. 

 

Yeah, I think anyone west of the GSP up in NRN NJ may be in trouble, east of that they'll probably survive with double digits or more.

Convection starting to flare to the SE of the death band (which looks to be around 40 DBZ  :o). Way to start off, guys. The storm at this point is E of the DelMarVa. Does anyone have any status of 7H and 5H? I think that 7H has closed off (according to Superstorm), but has H5 yet? The tilt is extremely negative so it should be almost there at this point.

I see nothing stopping that band from pivoting Westward and hitting the whole area. This storm is in no hurry and will eventually be stalling. 

u should be good for 12-16 as long as these bands keep rotating...16 would do it

I really dislike the subtle drop off in accums west and north of Essex, Bergen, Middlesex, and Union counties. I think the drop off will be severe and it's more a function of subsidence and very intense snows just to the east, than anything else...

 

Something else to consider is very dry air, low dews etc. Couple that with subsidence and it is little wonder why the westward progression has moved at a snail's pace.

 

Nevertheless, on the positive side, this system is still rapidly intensifying and has yet to close off at the upper levels. As such the westward expansion of the precip field is NOT close to being over. The best and easiest way to see this is on radar, and watching the intense bands continuing to march westward. Shortly after the system closes off at H500, that progression will cease, and you will see these bands sit over one location...Until then, keep watching the radar...

It seems closed off at 700 though.  and almost at 500.     A few more hours?

..HEAVY SNOW WILL IMPACT BRONX...EASTERN PUTNAM...FAIRFIELD...KINGS
(BROOKLYN)...MIDDLESEX...NASSAU...NEW HAVEN...NEW LONDON...QUEENS...
SUFFOLK AND WESTCHESTER COUNTIES...

AT 943 PM EST...NATIONAL WEATHER SERVICE DOPPLER RADAR WAS TRACKING
MULTIPLE BANDS OF HEAVY SNOW WORKING WEST FROM SUFFOLK COUNTY AND
SOUTHEASTERN CONNECTICUT.

SNOWFALL RATES OF 2 TO 3 INCHES PER HOUR ARE EXPECTED WITH THE SNOW.

The band over Suffolk county currently is a beast. It's expanding to the north and continues to rotate westward. That should be arriving in NYC and NE NJ by 11:30-12:00 or so. Pretty much right on target for when the core of the storm was set to begin. 

 

Looks like H5 is getting ready to close off.

Guess they figure no one in Manhattan is traveling.  We can't leave the island anyway.

It probably has a couple of more hours to move west. As Jbenedet said, the upper levels haven't closed off yet and the radar still has good westward momentum. Where the bands stop is where there will likely be huge totals, since they won't pivot back east for quite some time.

Getting nervous as Joe Cioffi on FB says he's worried if this doesn't close off soon much of the precip will go east. He said he will drastically cut amounts to the west if it doesn't do so soon. Says he has a new map ready to go. Hope that's not the case.

Correct I should have clarified--it is closed at 700. Model consensus is that this doesn't close off at H500 until around 10z Tuesday.

Yes and when it closes off, it will stop the westward progression but it will also be at its strongest. This is why long island and parts of Connecticut were so destroyed in February 2013. It closed off at H5 and just dumped on these areas.

jbenedet this seems to be in conflict with your comment. Hoe does a closed low at 500 MB affect precip? Cioffi seems to imply that closing brings it west, while you say closing off at H5 pins it.

Yea. On a second look though this appears to want to close off earlier, around 6z or so...

 

Still plenty of time though...
