This is reminding me of the Feb 2014 where the weak overrunning wave was in southern NC into SC and then the follow up coastal.  The CMC just goes nuts over the piedmont into the MA....still going after this panel too.

Apparently we have a lot to sort out, lol.  UKMet kind of looks like this too...hard to tell on the specifics though

LOL...yep.  This is kind of a bummer, I just want a simple weak wave with overrunning, 2-4" deal.  These big coastals never work out for RDU, though being further west like CLT would do better.  But, if the alternative is seeing lots of folks get plastered even if it was a cold rain for RDU then that's not to bad.  Starting to get aggravated there is even something to track, I hadn't looked at models in a couple of weeks and was loving the warmth.

What's aggravating is us dropping our subscriptions and now scratching and clawing various sites for model output

Love the GEM and Ukie. Heck nam not to shabby. Still not strike 3 yet for my big dog swing at the fence.

Yeah at this point you just gotta hope the NAM scores a win like it did back in Jan, it pretty much had it locked in by 72 hrs and never really wavered from there on in and it was close to perfect on how it played out....of course since the NAM is good for us here in the east it wont work out.

LOL...yep.

The GEM sure is eye candy...this looks to be a triple phaser.  If the NS energy would just drop a little further south.

WPC sums it up best...let's see what tomorrow shows.

WEAKENING SYSTEM REACHING THE WA COAST BY 10/1200Z RAPIDLY
DROPPING THROUGH THE CENTRAL PLAINS INTO THE TN VALLEY EARLY
SUNDAY AND CAROLINAS LATE SUN
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PREFERENCE: GENERAL MODEL BLEND THROUGH 11/00Z
            12Z GFS/00Z ECMWF BLEND
CONFIDENCE: ABOVE AVERAGE PRIOR TO 11/00Z
            SLIGHTLY BELOW AVERAGE

WV MOSAIC SHOWS A FAIRLY ROBUST SYSTEM NEARING THE WEST COAST
THOUGH INDICATING THE STRONG SHEARING FORCES TOWARD THE NORTHEAST
UNDER INFLUENCE OF STRONG SUBTROPICAL JET/LOW LEVEL MOISTURE
STREAM REACHING THE APEX OF THE GLOBAL RIDGE LOCKED OVER THE GREAT
BASIN.  MODELS SHOW STRONG AGREEMENT THROUGH THE LANDFALL OF THE
SFC WAVE INTO VANCOUVER ISLAND AND INTO THE NORTHERN
ROCKIES/INTERMOUNTAIN WEST TO PROVIDE ABOVE AVERAGE CONFIDENCE IN
SUPPORTING A GENERAL MODEL BLEND PRIOR TO 11/00Z.  HOWEVER...AS
THE WAVE OVER-TOPS THE MEAN RIDGE INTO TIGHT/STRONG NW FLOW MODEL
SOLUTIONS BEGIN TO DIVERGE DUE TO SLIGHT TIMING DIFFERENCES AS
WELL AS THE ORIENTATION OF THE SHORTWAVE ENTERING THIS
FLOW...CREATING A HIGHLY SENSITIVE TIME STEP TOWARD DOWNSTREAM
EVOLUTION.   ENSEMBLE TRENDS HAVE BEEN TOWARD A SLIGHTLY
FASTER/PROGRESSIVE SOLUTION WITH EVENTUAL INCREASED PHASING WITH
THE SOUTHERN STREAM ENERGY EMERGING FROM THE GULF COAST SAT INTO
SUN INTIMATELY TYING THE TWO WAVES SUN ACROSS THE SOUTHEAST.

THE 00Z UKMET CONTINUES TO BE A BIT DEEPER AND ELONGATED THROUGH
THE PLAINS AND EVENTUALLY SLOWS IN THE PROGRESSIVE FLOW...WHICH
SEEMS OUT OF PLACE.  THE 12Z NAM AND GFS BOTH ENTER THE NORTHWEST
FLOW A BIT MORE AMPLIFIED THAN THE 00Z ECMWF/CMC AND THIS
CONTINUES TO COMPOUND THROUGH THE CENTRAL PLAINS.  THE 12Z NAM
CONTINUES WITH A MORE AMPLIFIED SOLUTION THAN THE GFS AFTER
CROSSING THROUGH THE CENTRAL PLAINS INTO THE MID TO LOWER MS
VALLEY AND SLOWS WITH INFLUENCE OF THE SOUTHERN STREAM.  THE 00Z
ECMWF IS GENERALLY FLAT IN THE NORTHERN STREAM WITH A BIT LESS
PHASING FAVORING A MORE CONVECTIVE INFLUENCED SOUTHERN
STREAM...INCREASING THE POSITIVE TILT ACROSS THE GULF COAST...THIS
WEAKENS THE SOLUTION IN THE NORTHERN PORTION CROSSING THE
CAROLINAS.  THE 12Z GFS SHOWS GOOD TIMING AND FAIRLY AGREEABLE
STRENGTH OF THE WAVE WITH THE ECMWF WHICH CONTINUES THROUGH THE
SOUTHEAST BUT WITHOUT THE INFLUENCE OF THE CONVECTIVE SOLUTION THE
ECMWF PRESENTS IN THE SOUTHERN STREAM...LEADING TO A QUICK
TRANSITION THROUGH THE SOUTHEAST WITH A WEAK SURFACE WAVE
DEVELOPING OFF THE COAST.   GEFS SUPPORTS THE GFS...AND ECENS MEAN
FAVORS THE ECMWF UNSURPRISINGLY BUT OVERALL ARE QUITE AMENABLE
THROUGH THE FORECAST THROUGH THE CENTRAL PLAINS/SOUTHEAST.  AS
SUCH A 12Z GFS/00Z ECMWF BLEND IS PREFERRED THOUGH GIVEN THE LARGE
SPREAD AND HIGH SENSITIVITY AFTER 11/00Z TO THE
TIMING/SHAPE...CONFIDENCE IS SLIGHTLY BELOW AVERAGE AFTER 11/00Z.
