ALB is all in it seems  :weenie:  :snowing:

FOR

NOW...WE WILL FOLLOW THE LEAD OF WPC AND FAVOR THE 29/12Z

ECMWF...WHICH STILL SHOWS A SIGNIFICANT STORM SYSTEM FOR OUR ENTIRE

AREA...AND LOOKS TO BE A GOOD COMPROMISE. WE WILL GO WITH LIKELY

POPS FOR THURSDAY/THURS NIGHT...WITH POPS TAPERING DOWN THROUGH THE

DAY ON FRIDAY. TEMPS LOOK VERY COLD...WITH MINS BELOW ZERO OVER THE

HIGH TERRAIN AND SINGLE DIGITS IN VALLEY AREAS FOR THURSDAY NIGHT.

DURING THE DAY FRIDAY...HIGHS WILL ONLY BE IN THE SINGLE DIGITS TO

LOW TEENS OVER MUCH OF THE AREA.

 

BTV favoring the ECM as well over the GFS....

 

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...

AS OF 426 AM EST MONDAY...A RIDGE OF HIGH PRESSURE WILL BE OVER

THE REGION EARLY WEDNESDAY NIGHT. THIS HIGH WILL THEN RETREAT TO

THE NORTH LATE WEDNESDAY NIGHT. ECMWF AND GFS MODELS SHOWING SOME

DEVELOPING OVERRUNNING LIGHT SNOW WILL DEVELOP ACROSS THE REGION

AFTER MIDNIGHT WEDNESDAY NIGHT...AS WARM AIR ADVECTION ALOFT

OVERRIDES THE COLD ARCTIC AIR AT THE SURFACE. ON THURSDAY...THE

ECMWF AND GFS MODELS SHOW A LOW PRESSURE AREA WILL MOVE EAST FROM

THE OHIO VALLEY. HOWEVER...MODELS DIFFER AS TO THE TIMING OF THIS

LOW... WITH THE GFS MUCH FASTER THAN THE SLOWER ECMWF MODEL IN

BRINGING THIS LOW EASTWARD. THE UPPER TROUGH WITH THE ECMWF MODEL

IS FURTHER WEST THAN THE GFS AND AND DIGS FURTHER SOUTH AND IS

SHARPER THAN THE MORE PROGRESSIVE GFS MODEL. PREFER THE SLOWER

MOVEMENT OF THE ECMWF MODEL...AS THE GFS MODEL APPEARS TO BE TOO

FAST. HOWEVER... BOTH THE GFS AND ECMWF MODELS SHOWING THAT SNOW

THAT DEVELOPS OVER THE AREA LATE WEDNESDAY NIGHT WILL CONTINUE

INTO FRIDAY. THUS...BOTH MODELS SHOWING THIS WILL BE A FAIRLY LONG

DURATION EVENT. THIS WILL RESULT IN A SIGNIFICANT SNOWFALL ACROSS

THE REGION BY FRIDAY. GIVEN THE COLD ARCTIC AIR THAT WILL BE IN

PLACE ACROSS THE REGION THURSDAY AND FRIDAY...EXPECTING A DRY

FLUFFY SNOW AND NOT A WET SNOW WITH A HIGH WATER CONTENT.

THUS...THIS COULD RESULT IN SNOW TO LIQUID WATER RATIOS OF 20-1 OR

25-1. WE WILL LIKELY HAVE A BETTER IDEA AS WE GET CLOSER TO THE

EVENT. HAVE GONE WITH A DRY FORECAST FOR FRIDAY NIGHT.

HOWEVER...IF THE SLOWER ECMWF MODEL IS CORRECT...THEN SNOW COULD

LINGER ACROSS THE REGION INTO EARLY FRIDAY NIGHT. HIGH PRESSURE TO

BUILD INTO THE REGION ON SATURDAY WITH FAIR AND DRY WEATHER

EXPECTED

Wow... I hope the Euro scenario pans out.  I think the big lesson here is that when Tim Kelley says the word "blizzard" in a twitter post....it's time to pay attention.  Tim is really my favorite Meteorologist.  Unfortunately I can only watch him when I'm at the gym since I get Dish Network and not Comcast.   :offtopic:

When TK says "hurricane", though, pay no heed.
