THE ECMWF HAS BEEN A MODEL OF CHOICE PRIMARILY FOR ITS HANDLING OF
THE SURFACE COLD AIR AND INITIAL ONSET OF PRECIPITATION. THE 12Z GFS
CAME IN VERY CLOSE TO THE ECMWF. THE NAM IS THE MOST NOTABLE OUTLIER
IN THE SENSE THAT IT PROBABLY DOES NOT MOVE THE COLD AIR QUICKLY
ENOUGH TUESDAY IN THE WAKE OF A NORTHERN STREAM WAVE. THE NAM ALSO
INDUCES A STRONGER PRESSURE WAVE AT LOW LEVELS ALONG THE FRONT ON
WEDNESDAY...WHICH RESULTS IN CYCLOGENESIS AND EVEN GREATER SNOWFALL
THAN APPEARS IN OUR FORECAST. WHILE THE NAM AT LEAST REPRESENTS ONE
POSSIBILITY WITHIN THE SPECTRUM...IT DOES NOT HAVE SUPPORT FROM
OTHER GUIDANCE...AND DOES NOT APPEAR LIKELY...AS THE MID LEVEL
FORCING SHOULD REMAIN LOCATED WELL NORTH OF THE FRONT.

EDIT: This is what i was talking about.

Extremeweatherguy wrote:One thing to point out about the GFS snow map above is that it is showing snow accumulations using a 10:1 ratio. According to the Cobb output though, ratios over the course of this storm should average well over 15:1 across central Oklahoma, even peaking above 20:1 at times. This means that actual accumulations could be even higher than the GFS map above suggests (assuming the actual model QPF verifies).
You can view a breakdown of the 00z GFS snow ratios (as well as a variety of other text data) for OKC and OUN using the links provided below:
OKC: http://www.meteor.iastate.edu/~ckarsten ... &site=kokc
OUN: http://www.meteor.iastate.edu/~ckarsten ... s&site=oun
IN OKLAHOMA...HOWEVER...IT LOOKS AS THOUGH THIS FRONTAL STORM
SYSTEM...DESPITE REMAINING OPEN/ NOT DEVELOPING A CLOSED LOW/...
WILL BE A VERY EFFICIENT SNOW PRODUCER. THE TEMPERATURE PROFILES ARE
JUST SO FAVORABLE FOR MODERATE TO HEAVY SNOWFALL...GIVEN THAT THE
COLD AIR IS ALREADY IN PLACE...AND WILL GET COLDER...PLACING A DEEP
LAYER OF -10 TO -20 C AIR COINCIDENT WITH THE STRONGEST LIFT IN THE
CLOUD LAYER. STEEP LAPSE RATES ABOVE 600 MB SHOULD ALSO ENHANCE SNOW
GROWTH IN THE UPPER PART OF THE CLOUD...THUS SEEDING THE REST OF THE
CLOUD WITH NUCLEI FOR GROWTH BY ACCRETION.
