Post-Super Bowl Storm chance discussion

Yes a lot slower this run...we need it to occurred faster for something more...still verbatim solid hit. Just want consistency at this point

I was just looking at the 12z EPS individuals.  

 

A few of them are very strong miller B's and JMA esque.

 

member 46 tracks a surface low to Ohio and then Pitt which then transfers to the NJ coast. At the time of the transfer the low is at 986mb and ends up 973mb near Cape Cod. Ends up producing a foot plus from the Plains all the way to Maine.

 

There are 6-7 other members that produce a similar outcome.

Would assume those members are ejecting the SW energy or is the strong solution the result of the Northern Stream energy?

I wouldn't be shocked if some areas received 12"+ but I think that falls in a relatively narrow band to the south of the NYC area. Has the makings of a heart breaker for many people North of the city.

Seems every storm for the last 5 years has been higher amont S and E and lesser N and W.  Getting used to the heartbreak.

Anyone know what a "Cat 8 Snowfall" is?  Are they just trying to see who is paying attention?  I should post that on social media ;)

.LONG TERM /SATURDAY THROUGH THURSDAY/...
980S LOW SPINNING NEAR NOVA SCOTIA WILL KEEP GUSTY NW FLOW LOCKED IN
ON SAT...PRODUCING WIND CHILLS MAINLY AOB ZERO FOR MOST OF THE DAY.
AS WINDS SLACKEN LATE...WIND CHILLS WILL LIKELY RISE INTO THE SINGLE
DIGITS. H85 WINDS IN THE GFS ARE AROUND 55-60KT AT 12Z SAT...SO
THERE IS THE POTENTIAL FOR WIND ADVY EARLY WITH GUSTS IN THE 45-50
MPH RANGE. SUBSIDENCE ON THE WRN FRINGE OF THE SYS SHOULD AID IN THE
GUST POTENTIAL...WHILE AT THE SAME TIME CLEARING OUT THE SKIES.

WEAK HI PRES RIDGE SAT NGT SO MUCH LIGHTER WINDS INTO SUN.

MODELS LINING UP WITH THE NEXT SYS FOR SUN NGT AND MON. THE 12Z GFS
AND ECMWF ARE VIRTUALLY THE SAME WRT THE TRACK AND INTENSITY. AT 18Z
MON THE LOW CENTERS WERE APPROXIMATELY 60 MILES APART AND ABOUT 130
MILES S OF THE BENCHMARK. MOST OF THE GFS ENSEMBLE MEMBERS WERE
CLUSTERED ON THIS SOLN.

EXTENSIVE AREA OF MID LVL MOISTURE WITH THE SYS...SO WITH HIGH SLR/S
AT LEAST LGT-MDT ACCUMS POSSIBLE. BASED ON THE PROGRESSIVE
NATURE...IT LOOKS LIKE A 4-8 INCH POTENTIAL ATTM. THIS OF COURSE CAN
CHANGE...IN FACT A SRN TRACK COULD LEAVE THE CWA WITH JUST FLURRIES.
AS AN ASIDE...THE 12Z MEX HAS CAT 8 SNOWFALL FOR ALL SITES.

HI PRES MON NGT AND TUE. SUNNY ON TUE AS A RESULT.

Snow Amount Categories 0 = no snow or a trace expected; 1 = > a trace to < 2 inches expected; 2 = 2 to < 4 inches; 4 = 4 to < 6 inches; 6 = 6 to < 8 inches; 8 = ≥ 8 inches.

 

I believe the MOS is calculating a very high snow ratio for the the total precip since the

MOS temps are so cold.

FYI isentropic ratios will be 12-15:1 so 0.4-0.5 is more like 5-8

It's 15 to 1. There's a chance it's 20 in spots. It will b great in the snow growth areas .

.5 is 8 If u get lucky it could b 10.

We had 20 to 1 last year with an arctic wave. It's not impossible.

Just one statistical forecast model predicting 8 inches or more of snow that is 108 hours away.   :).

Doesn't this have more of a chance to phase and deepen further if we can get the trough to go at least neutral with a stronger ridge out west? Seems to me this one has potential for something a lot bigger especially w a blocking high and confluence to the east? Or am I being unrealistic?

This really to me looks to me like a 2/7/03 repeat and it's actually the #2 match at 500mb on CIPS. The pattern to me doesn't support much bigger than 4-8 or 6-10 with it
