Decent Analog to TS Joaquin Forecast Track

Not an official hurricane, but I think it was, despite being in Dec!  This
is a good candidate in the Re-analysis Project to go in the database
as a 70 kt hurricane.
 
Take a look at the position of the main baroclinic 500 low that pivoted
this system back to the NW.  Looks like what is forecast by some
of models (GFDL and HWRF).
 
 
And it ended up moving due W to just off the coast of NJ, where
it weakened and got absorbed by the developing ET low to near
Hatteras.  Smaller shallow system dictated by a bigger non-tropical
low?  What would you call it?!
 
12/23/1994
An intense ocean storm, known as the tropical hybrid
nor'easter, lashed New England with high winds and heavy rains
on this day and continued into the 24th.  The storm had its
origins in the western Gulf of Mexico two days before and had
the characteristics of a hurricane, even as it reached 40
degrees north latitude.  It dumbelled around a regular
developing baroclinic low on the coast of the Carolinas, and
had an extremely tight pressure pattern, with a central
pressure of 969 millibars as it approached New England.
High pressure to the north only enhanced the pressure gradient,
and resulted in winds exceeding hurricane force over coastal
areas.  A wind gust of 88 mph was recorded at Walpole,
Massachusetts.  Sustained winds of 63 mph with a gust to 84
mph were record on Nantucket Island.  Falmouth, Massachusetts
recorded a 78 mph wind gust and a 74 mph gust was reported at
Ashaway, Rhode Island.  Plymouth, Massachusetts was deluged
with 4.85 inches of rain and Gloucester, Massachusetts checked
in with 4.72 inches.

Screaming northeast winds: check

Heavy qpf: check

Above freezing column below 5,000 feet: wtf?

 

It was cold enough aloft for bright banding.  After all, it was December!

 

CoastalWx didn't live in NZW (South Weymouth) at the time, but look at these obs.  CBMAM, TS and GS in an outer band in the late aftn as it approached!  Alternative PT for a "winter" event? :P

 

Note: wind is in knots.

Interesting speculation. I see that the storm did not fully merge with the digging closed low. If a similar scenario were to occur now, Joaquin could end up heading farther up the coast than the NC or VA landfall suggested by a lot of the 00Z guidance. This will depend a lot on how far west/southwest Joaquin moves before turning north or northeast. If not fully captured by the closed low expected to develop over the Southeast, it will have more opportunity to head farther north.

Good call on this, with models showing the hurricane steered by but not captured by/merging with the closed low for a time. Looks like out to sea, can't totally rule out TS conditions on Cape Cod and the Islands yet if it passes by more closely a la GFS/GFDL?
