The episode as NWS AMA wrote it up.
A potent upper level low moved across southern New Mexico during the evening hours of February 20th. This system would go on to produce several inches of snow with a maximum of 12 inches in Texas County after making a transition from rain and sleet to all snow. As the upper level low moved into southeastern New Mexico it transitioned from a neutral tilt to a slightly negative tilt. This reorientation provided additional lift across the southwestern and eastern Oklahoma Panhandle which in turn helped intensify snowfall rates. It was in this area where the two highest snow depths occurred, 9 to 12 inch swath across southern Cimarron County and southwestern Texas County, and an 8 to 9 inch swath across southeastern Beaver County. By the early afternoon the upper level low had progressed over central Kansas, removing forcing across the Panhandle and bringing an end to precipitation. The following is a listing of the highest storm total snowfall for each county: 12.0 inches in Texhoma (Texas County); 9.0 inches nine miles southeast of Boise City (Cimarron County); 9.0 inches in Slapout (Beaver County).

NATIONAL WEATHER SERVICE AMARILLO TX
651 PM CST WED FEB 20 2013
.UPDATE...
ADDED FOG FOR ALL LOCATIONS TONIGHT AND ISSUED A DENSE FOG ADVISORY
FOR THE SOUTHWESTERN TEXAS PANHANDLE THROUGH 6 AM THURSDAY.
&&
.DISCUSSION...
A VERY MOIST, UPSLOPE SURFACE FLOW IS EXPECTED TO CONTINUE OVERNIGHT.
AS A RESULT, FOG WILL LIKELY CONTINUE ACROSS A LARGE CHUNK OF THE
AREA, ESPECIALLY BEFORE ANY SNOW DEVELOPS. TXDOT WEB CAMS AROUND THE
SOUTHWESTERN TEXAS PANHANDLE SHOW VERY POOR VISIBILITIES ON AREA
ROADWAYS. THE FOG MAY BREAK ONCE THE SNOW BEGINS LATER THIS EVENING,
BUT UNTIL THAT HAPPENS, WE EXPECT THE PEA SOUP TO REMAIN IN PLACE.
WE'LL BE WATCHING TO SEE IF WE NEED TO EXPAND THE ADVISORY, BUT AT
THIS TIME, OBSERVATIONS SUGGEST THE WORST FOG WILL BE CONFINED TO THE
SOUTHWEST TEXAS PANHANDLE. UPDATED PRODUCTS HAVE BEEN SENT.

DISCUSSION...
SHORT TERM...
GOOD AGREEMENT ON TIMING WITH THE WINTER WEATHER FOR
TODAY THROUGH THURSDAY AFTERNOON BUT DIFFERENCES REMAIN ON TYPE AND
TIMING OF PRECIP CHANGE OVER.
CURRENTLY THE FIRST OF THIS TWO PRONGED SYSTEM IS STRETCHED ACROSS
THE NORTHERN TEXAS AND OKLAHOMA PANHANDLES. THIS COUPLED WITH MODEST
ELEVATED INSTABILITY HAS ALLOWED A FEW CLAPS OF THUNDER ACROSS THE
NORTHWEST TEXAS PANHANDLE AND EASTERN OKLAHOMA PANHANDLE. THE
CONVECTIVE INFLUENCE OF THESE STORMS HAS HELPED TO COOL THE
ATMOSPHERE ENOUGH FOR BRIEF PERIODS OF SLEET AND SNOW. AWAY FROM
THESE STORMS ANY PRECIP THAT HAS FALLEN HAS BEEN IN THE FORM OF
LIQUID.
LOOKING FORWARD INTO THE EVENING HOURS THERE COULD BE A BRIEF WINDOW
WHERE LITTLE TO NO PRECIP OCCURS PRIOR TO THE INFLUENCE OF THE NEXT
AND MAIN DISTURBANCE. THERE REMAINS GOOD AGREEMENT BETWEEN THE ECMWF
AND NAM ON THE SPEED AND LOCATION OF THE DISTURBANCE WITH THE GFS
BEING A LITTLE FAST WITH THE SYSTEM. HAVE GONE WITH A NAM ECMWF
BLEND FOR THE OVERALL FORECAST WHICH WILL SLOW THE SYSTEM SLIGHTLY
AND EXTEND PRECIP CHANCES INTO THURSDAY AFTERNOON. THERE IS A CHANCE
PRECIP MAY CONTINUE TO FALL BEYOND 6 PM THURSDAY IN THE NORTHEASTERN
OKLAHOMA PANHANDLE SHOULD THE SYSTEM SLOW MUCH MORE.
THE MOST RECENT RUNS OF THE NAM HAVE SHOWN A SLIGHT WARMING TREND
DURING THE OVERNIGHT HOURS BUT IT STILL REMAINS COOLER THAN THE GFS
DUE TO THE DIFFERENCES IN THE LOCATION OF THE SURFACE LOW. THE NAM
BRINGS THE LOW CENTER FURTHER TO THE SOUTH PLACING THE PANHANDLES ON
THE COOLER SIDE OF THIS SYSTEM. THIS HAS HAD THE BIGGEST IMPACT ON
PRECIP TYPES AND INTENSITY WITH THE MAIN WAVE. HAVE STUCK WITH A
BRIEF PERIOD OF SLEET TONIGHT AS RAIN MIXES WITH SNOW BEFORE
TRANSITIONING TO ALL SNOW AROUND 9Z. THERE STILL REMAINS SLIGHT
ELEVATED INSTABILITY WITH THE MAIN WAVE SO INCLUDED MENTION OF
MODERATE SNOW AFTER 9Z. BY NOON THURSDAY ANY SNOW OCCURRING SHOULD
BE LIGHT AS PRECIP BEGINS TO END FROM SOUTHWEST TO NORTHEAST.
OVERALL KEEPING 6 TO 8 INCHES WITH LOCALLY HIGHER AMOUNTS POSSIBLE IN
THE NORTHEAST TEXAS AND EASTERN OKLAHOMA PANHANDLES...WITHIN THE
WINTER STORM WARNING...AND 1 TO 5 INCHES ACROSS THE REMAINDER OF THE
AREA...WITHIN THE WINTER WEATHER ADVISORY.
LONG TERM...
A SHORT WAVE TROUGH DROPS SOUTHEAST THROUGH THE 4 CORNERS THURSDAY
NIGHT AND INTO NORTHERN NEW MEXICO BY FRIDAY MORNING. THIS
DISTURBANCE DOES NOT HAVE A LOT OF MOISTURE TO WORK WITH...BUT IT
STILL LOOKS LIKE IT WILL BE STRONG ENOUGH TO BRING SOME LIGHT SNOW
TO NORTHERN PARTS OF THE CWA ON FRIDAY NIGHT AS IT MOVES ACROSS THE
PANHANDLES. AT THIS TIME...ANY ACCUMULATIONS WILL BE UNDER ONE INCH.
ANOTHER SHORT WAVE TROUGH MOVES SOUTHEAST INTO THE GREAT BASIN BY
SATURDAY NIGHT AND THEN IT STRENGTHENS AS IT DROPS INTO NORTHERN
NEW MEXICO BY SUNDAY MORNING. THIS SHORT WAVE IS A LITTLE STRONGER
THAN THE ONE FOR FRIDAY NIGHT...SO CHANCES OF SNOW MAY BE A
LITTLE MORE WIDESPREAD. AT THIS TIME...IT LOOKS LIKE ANY SNOW
ACCUMULATIONS WILL BE ON THE LIGHT SIDE...BUT IF THE FURTHER SOUTH
ECMWF MODEL IS CORRECT...THEN ACCUMULATIONS COULD BE A LITTLE
HEAVIER...MAINLY ACROSS THE NORTH.
ANOTHER SHORT WAVE TROUGH MAY START TO AFFECT THE PANHANDLES BY MID
WEEK NEXT WEEK. RIGHT NOW THE MODELS DO NOT AGREE ON THE TRACK AND
STRENGTH OF THIS NEXT SYSTEM...SO HAVE NOT ADDED ANY POPS AT THIS
POINT SINCE CONFIDENCE IS NOT VERY HIGH.
TEMPERATURES LATE THIS WEEK INTO THE WEEKEND WILL BE TRICKY DEPENDING
ON HOW MUCH SNOW FALLS TONIGHT AND THURSDAY...SO EXPECT SOME MORE
TWEAKS IN HIGHS AND LOWS WHERE THE HEAVIEST SNOW FALLS AND LINGERS.
FIRE WEATHER...
THE STORM SYSTEM MOVING ACROSS THE PANHANDLES TONIGHT AND THURSDAY
SHOULD PROVIDE ENOUGH PRECIPITATION TO KEEP ANY FIRE WEATHER
CONCERNS TO A MINIMUM THROUGH EARLY NEXT WEEK.
