What happened

The episode as NWS AMA wrote it up.

A vigorous mid-level trough of low pressure moved out of southeastern New Mexico and into west central Texas during the early morning hours of December 25th. The lift provided by this system and low level wrap around moisture caused light snow showers to form over the Southern Plains. The snow showers persisted for several hours to produce at least 1 inch of accumulated snow in every county in the Oklahoma Panhandle. The snow fall began to diminish during the early evening hours as the upper low continued its eastward path into southern Arkansas and northern Louisiana.|The following is a list of snow amounts across the Oklahoma Panhandle: Beaver (Beaver County) 1.0 inch; Slapout (Beaver County) 1.0 inch; Boise City (Cimarron County) 1.0 inch; and Guymon (Texas County) 1.0 inch.

.PREV DISCUSSION... /ISSUED 509 AM CST TUE DEC 25 2012/

DISCUSSION...
ATTENTION OBVIOUSLY REMAINS ON SNOW AND BLOWING SNOW TODAY...AND
LINGERING COLD TEMPERATURES TONIGHT INTO WEDNESDAY MORNING.

ANTICIPATED CHRISTMAS SNOW IS CURRENTLY TAKING SHAPE ACROSS THE
REGION. WITHIN THE BROADER MID/UPPER-LEVEL TROUGH WORKING OUT OF THE
CENTRAL AND SOUTHERN ROCKIES INTO THE HIGH PLAINS...THE MID-LEVEL LOW
CENTER OVER CO HAS BEEN WEAKENING WITH A NEW CLOSED LOW DEVELOPING
FARTHER SOUTH ALONG THE TX/NM BORDER. IN RESPONSE TO THIS...DEFORMATION
SNOW BAND OVER CO AND KS IS EXPECTED TO FADE THIS MORNING WHILE THE
FARTHER SOUTH PRECIP BAND CURRENTLY ARCING FROM OK ACROSS THE
PANHANDLE INTO THE WESTERN SOUTH PLAINS/FAR EASTERN NM BECOMES THE
MAIN SHOW. STRONGEST ECHOES THUS FAR ACROSS THE FORECAST AREA HAVE BEEN
IN THE FAR SOUTHWEST TX PANHANDLE WITH CONFIRMED REPORTS OF SNOW
FALLING IN THIS AREA. ELSEWHERE...OBSERVATIONS SUGGEST THAT TOP-
DOWN MOISTENING IS STILL OCCURRING WITH PRECIP NOT YET REACHING THE
GROUND IN MOST LOCATIONS.

AS THE CLOSED MID-LEVEL LOW TRACKS JUST SOUTH OF THE PANHANDLES THIS
MORNING...SNOW WILL EXPAND ACROSS THE AREA WITHIN THE MID-LEVEL
DEFORMATION ZONE...WITH MID-LEVEL FRONTOGENETIC FORCING AND
ISENTROPIC LIFT ENHANCING THE FORCING. SHORT-RANGE MODELS ARE IN GOOD
AGREEMENT SHOWING A RESULTANT BAND OF HEAVIER SNOW FALLING FROM THE
SOUTHWEST TX PANHANDLE NORTHEAST INTO THE NORTHEAST TX
PANHANDLE...WHICH LINES UP WELL WITH REAL-TIME DATA AT THIS POINT.
THUS HAVE PAINTED SNOW ACCUMS IN THE 3-5 INCH RANGE IN THIS
SWATH...TAPERING OFF TO AN INCH OR LESS IN THE WESTERN OK PANHANDLE
AND FAR SOUTHEAST TX PANHANDLE. WILL SEE SOME INTENSE SNOWFALL AT
TIMES IN THE STRONGEST BANDING...AND MAY SEE SOME CONVECTIVE
ENHANCEMENT TO THIS BANDING AT TIMES. HOWEVER...THE SYSTEM IS QUITE
PROGRESSIVE AND THE SNOW WILL START TO SHUT DOWN FROM WEST TO EAST
LATE THIS MORNING AS SUBSIDENCE AND ISENTROPIC DOWNGLIDE SETS IN ON
THE BACKSIDE OF THE SYSTEM. GIVEN THE RELATIVELY SHORT DURATION OF
THE EVENT...BELIEVE SNOWFALL AMOUNTS WILL REMAIN BELOW WARNING
CRITERIA OF 6+ INCHES IN MOST LOCATIONS AND THUS WILL KEEP THE
ADVISORY IN PLACE AREA WIDE. HOWEVER CANNOT RULE OUT A COUPLE
ISOLATED AMOUNTS TIPPING INTO THE 6 INCH RANGE IF A STRONGER BAND IS
ABLE TO STAY OVER ONE LOCATION LONG ENOUGH. WOULDN/T BE SURPRISED TO
SEE SOME 1 INCH/HOUR ACCUMS IN SOME SPOTS THIS MORNING FOR 4-5 HOURS.
WINDS STILL EXPECTED TO BE IN THE 20-30 MPH RANGE WITH GUSTS UP TO 45
MPH IN THE TIGHTENED POST-FRONTAL PRESSURE GRADIENT...WHICH WILL
LIKELY LEAD TO WHITEOUT CONDITIONS AT TIMES...AND WILL ALSO PRODUCE
SUB-ZERO WIND CHILLS THIS MORNING.

THE SNOW IS EXPECTED TO END ACROSS THE ENTIRE CWA BY LATE THIS
AFTERNOON. WINDS WILL STEADILY DECREASE TONIGHT...BUT SUB-ZERO WIND
CHILLS ARE STILL LIKELY AGAIN TONIGHT AS LOWS FALL INTO THE SINGLE
DIGITS IN MOST LOCATIONS. LOW AND MID CLOUDS WILL CLEAR OUT FROM WEST
TO EAST TONIGHT...BUT HIGH CLOUDS WILL THICKEN FROM THE WEST LATER
TONIGHT WHICH SHOULD HELP KEEP LOWS FROM CRATERING EVEN FARTHER. MAY
NEED A WIND CHILL ADVISORY TONIGHT INTO WEDNESDAY MORNING FOR PARTS
OF THE AREA IF WINDS STAY UP ABOVE 10 MPH. FOR SIMPLICITY
SAKE...WILL LET THE SNOW EVENT WIND DOWN THIS AFTERNOON BEFORE
CONSIDERING ISSUING ANOTHER ADVISORY FOR THIS.

NO SIGNIFICANT CHANGES MADE TO THE REMAINDER OF THE FORECAST. NEXT
UPPER TROUGH IS PROGGED TO EJECT INTO THE PLAINS THURSDAY
NIGHT/FRIDAY...PUSHING A COLD FRONT THROUGH THE CWA THURSDAY NIGHT.
STILL MIXED SIGNALS ON POSSIBLE SPOTTY LIGHT SNOW THURSDAY
NIGHT/FRIDAY...BUT IF ANY PRECIP FALLS...IT LOOKS TO BE VERY LIGHT.
DRY CONDITIONS AND MODERATING TEMPS THEN ANTICIPATED FOR THE WEEKEND
INTO EARLY NEXT WEEK.

KB

FIRE WEATHER...
NO ELEVATED OR CRITICAL FIRE WEATHER CONDITIONS ARE ANTICIPATED
THROUGH EARLY NEXT WEEK.
