A great disco from BOX on potentials

 

FRIDAY INTO SATURDAY ...


DOUBLE-BARREL LOW / MILLER-B TYPE SIGNATURE? NEVERTHELESS STORM
SYSTEM APPROACHING TOWARDS SATURDAY MORNING RAPIDLY DEEPENING ACROSS
THE 40N/70W BENCH-MARK POTENTIALLY DOWN TO 980-970 MB ... QUICKLY
EXITING LATE. FORECAST GUIDANCE CONSENSUS PREFERRED AS THERE IS GOOD
CLUSTERING WITH DETERMINISITIC / ENSEMBLE SOLUTIONS ... MINUS THE
CANADIAN /WOMP WOMP/.

COMPLICATIONS: LACK OF ARCTIC AIRMASS ACROSS CANADA CONSIDERING N-
WINDS WITH ISALLOBARIC RESPONSE ... QUICK DAYTIME PASSAGE ... SOME
UNCERTAINTY AS TO WHETHER THE STORM UNDERGOING MATURATION CLOSES-OFF
COMPLETELY DURING IMPACT /POTENTIAL TROWALING/ ... THERMAL PROFILES
AND SUBSEQUENT RAIN / SNOW TRANSITION LINES ... ALONG WITH SNOW-TO-
LIQUID RATIOS /POTENTIALLY ISOTHERMAL UP TO H7 NEAR-FREEZING ...
PERHAPS A MORE WET-SNOW ... HEAVY PACKING WITH ACCUMULATION/.

OVERALL LOOKING LIKE A RAIN/SNOW SETUP WHERE THICKNESSES AND THERMAL
PROFILES ARE KEY. A CONSENSUS OF FORECAST GUIDANCE AS NOTED ALONG
WITH CIPS ANALOGS ... LOOKING AT A SW-NE TRANSITION LINE WITH
COASTAL-FRONT INFLUENCES PER ONSHORE FLOW. ACCUMULATING SNOWS AWAY
FROM THE SHORE AND COASTAL PLAINS ... ACROSS THE N/W INTERIOR WITH
FOCUS ALONG THE E-SLOPES OF HIGH TERRAIN. COULD SEE A LOT OF
MOISTURE WITH THIS SYSTEM WITH CONSENSUS PRECIPITATION AMOUNTS IN
EXCESS OF AN INCH. THERE IS SOME POSSIBILITY WE WILL BE CONTENDING
WITH WINTER WEATHER HEADLINES. THIS IN ADDITION WITH A ROBUST
DEEPENING SYSTEM ... COULD BE DEALING WITH WIND HEADLINES AS WELL
ALONG THE COAST / COASTAL PLAINS.

AS THE SYSTEM LIFTS OUT LATE ... RAIN TRANSITIONING BACK TO SNOW
TURNING LIGHT. PERHAPS SOME LIGHT ACCUMULATIONS PRIOR TO EVERYTHING
WINDING DOWN ALONG WITH WINDS.

Pretty typical early season 95 corridor, all changeover backside though. I mean't it when i said it we are a month behind

I know you do.  I just don't see this a a pure "snow" event for the coastal plain.

I'm still on the fence on areas along and N of the I-90 corridor and possibly even further N being all snow as well.  We really need the primary to come in substantially weaker to minimize the warmth ahead of this.
