The episode as NWS FWD wrote it up.
A strong upper level system and cold front first brought hail-producing thunderstorms to the region, then a winter weather event that included snow and sleet. The storms produced lots of pea sized hail and occasionally slightly larger hail. The snow fell generally north of a line from Breckenridge to Palestine. The greatest concentration of heavy snow was in western Denton County and Collin County where 4-6 of snow fell. There were also isolated locations that received 4-6 of snow in Parker, Grayson, Fannin, Hunt, and Emory counties. The overall impacts from the sleet and snow were minimal but there were the usual impacts to transportation in the region when the snow froze on area roads that night; especially on elevated roadways, bridges, and overpasses.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Dec 24, 11:50 PM CST, 2 hours 20 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 1150 PM CST MON DEC 24 2012 .AVIATION... /06Z TAFS/ CONCERNS...THREAT FOR THUNDER OVERNIGHT AND EARLY TUESDAY MORNING. CHANGE OVER TO SNOW IN THE DFW METROPLEX TUESDAY AFTERNOON. STRONG AND GUSTY NORTHWEST WINDS TUESDAY AFTERNOON THROUGH THE OVERNIGHT HOURS. WIDESPREAD LIGHT SHOWERS ARE ALREADY DEVELOPING ACROSS THE REGION AND MVFR STRATUS IS SPREADING NORTH INTO WACO. THE METROPLEX TAF SITES WILL REMAIN VFR UNTIL THE PRECIPITATION INCREASES BY 08-09Z BUT WACO WILL CONTINUE IN MVFR THROUGH THE NIGHT. EXPECT SHOWERS AND SCATTERED THUNDERSTORMS TO OCCUR THROUGH THE OVERNIGHT HOURS WITH REDUCED VISIBILITIES AND MVFR CIGS. THE POTENTIAL FOR THUNDER IS HIGHER AT WACO AND SOME SEVERE STORMS ARE POSSIBLE AROUND THE WACO AREA AS WELL...WITH A THREAT FOR HAIL. LATEST GUIDANCES SUGGEST THE SHOWER ACTIVITY COULD BECOME HEAVIER CLOSER TO DAYBREAK AS AN UPPER LEVEL LOW GETS CLOSER TO THE REGION AND LIFT INCREASES. THIS COULD RESULT IN TEMPORARY IFR CONDITIONS AT ALL TAF SITES DURING PERIODS OF HEAVY SHOWERS AND/OR THUNDERSTORMS. THE PRECIPITATION WILL CONTINUE FOR MOST OF THE DAY WITH A CHANGE OVER TO SNOW IN THE DFW METROPLEX IN THE EARLY TO MID AFTERNOON HOURS. THERE COULD ALSO BE A BRIEF WINDOW OF SLEET MIXED IN AS WELL BEFORE THE CHANGE OVER TO ALL SNOW. THE SNOW WILL LAST FOR A FEW HOURS AND ACCUMULATIONS UP TO AN INCH ARE POSSIBLE. AT THIS SAME TIME...A STRONG FRONT WILL SWEEP ACROSS THE METROPLEX RESULTING IN VERY STRONG NORTHWEST WINDS. THE WINDS COULD CAUSE BLOWING SNOW THAT COULD REDUCE VISIBILITIES. CONDITIONS OVERALL SHOULD INCREASE IN THE EVENING HOURS AS THE SYSTEM MOVES EAST...BUT THE STRONG WINDS WILL CONTINUE OVERNIGHT. AT KACT...THE PRECIPITATION IS EXPECTED TO REMAIN ALL LIQUID... ENDING DURING THE AFTERNOON HOURS. THE FRONT WILL ARRIVE AROUND MIDDAY. THERE IS A SMALL CHANCE FOR SOME FLURRIES BUT THE POTENTIAL IS FAIRLY LOW. CEILINGS SHOULD IMPROVE AT ALL SITES TUESDAY EVENING BUT THERE IS A POTENTIAL THAT THE MVFR CIGS BEHIND THIS SYSTEM COULD HOLD IN LONGER THAN IS IN THE CURRENT TAF FORECAST. 82/JLD && .UPDATE... WE HAVE ANALYZED THE 00Z UPPER AIR DATA AND HAVE WATCHED THE SURFACE OBS CLOSELY FOR SIGNS OF ANY DISCREPANCIES BETWEEN THEM AND THE MODEL DATA. THE BIG THING THAT STANDS OUT ARE THAT THE SURFACE LOW IN NORTHEAST NEW MEXICO AT 6PM WAS ABOUT 80 MILES FARTHER SOUTH THAN ALL OF THE MODELS HAD FORECAST 24 HOURS AGO. WHEN DEALING WITH A SWINGING/DIGGING UPPER LEVEL SYSTEM...THE SURFACE PRESSURE PATTERN AND PRESSURE TENDENCIES OFFER ENORMOUS CLUES ON THE FUTURE TRACK OF A POTENTIAL VORTICITY ANOMALY BEFORE IT CLOSES OFF TO BECOME A FULL FLEDGED UPPER LOW. THE 3PM AND 6PM SURFACE ANALYSIS SHOWED A LARGE REGION OF PRESSURE FALLS ACROSS NEW MEXICO AND WEST TEXAS IN ADVANCE OF THE SYSTEM. GIVEN THE ORIENTATION OF THE PRESSURE FALLS AND LOCATION OF THE SURFACE LOW...IT CAN BE DETERMINED WITHOUT EVEN LOOKING AT A FORECAST MODEL THAT THE UPPER LOW HAS NOT FINISHED DIGGING SOUTH. THE BIG QUESTION IS HOW FAR SOUTH WILL THE UPPER LOW MAKE IT BEFORE IT BEGINS TO SWING BACK TO THE NORTHEAST. AT THIS HOUR PRESSURE FALLS CONTINUE IN THE REGION FROM LUBBOCK TO MIDLAND...WITH ANOTHER PRESSURE FALL AREA DEVELOPING IN SOUTHEAST TEXAS. EXTRAPOLATING SUGGESTS THE UPPER LOW WILL TRACK JUST SOUTH OF LUBBOCK BY SUNRISE AND TO NEAR WACO BY SUNSET. AS THE LOW APPROACHES WACO...A WARM FRONT WILL BE ORGANIZING OUT OF THE WEAK STATIONARY FRONT CURRENTLY ANALYZED FROM SAN ANTONIO TO HOUSTON. BAROCLINIC QG THEORY SUGGESTS THAT ONCE LOW LEVEL WARM ADVECTION BEGINS IN EARNEST ACROSS SOUTHEAST TEXAS BY MORNING...IT WILL INDUCE HEIGHT RISES TO THE SOUTHEAST OF OUR UPPER LOW WHICH WILL CAUSE THE LOW TO CLOSE OFF AND FINISH DIGGING SOUTH...AND START ITS GRADUAL TURN TO THE NORTHEAST. TOMORROW EVENING I WOULD EXPECT THE LOW TO TRACK FROM NEAR WACO TO NEAR SHREVEPORT. IN SUMMARY THE USUAL MEDIUM RANGE MODELS APPEAR TO BE A LITTLE TOO FAR NORTH WITH THE TRACK OF THE UPPER LOW. OUR EXPECTATIONS FOR THE TRACK OF THE LOW ALIGN WELL WITH THE RAP FORECAST WHICH IS TO THE SOUTH OF ALL OTHER MODELS...SO WE WILL USE THE RAP HEAVILY. OUR FORECAST HAS BEEN ON THE SOUTHERLY SIDE AND SNOWIER SIDE OF THE MODEL GUIDANCE. SO ALTHOUGH WE ARE SEEING AN EVEN MORE SOUTHERLY TRACK COME TO FRUITION...THIS DOES NOT NECESSARILY MEAN THE FORECAST SNOW AMOUNTS NEED TO BE AMENDED MUCH. THIS IS IN PART DUE TO THE DIFFICULTY IN GETTING THE COLDER/SUBFREEZING AIR FARTHER SOUTH BEFORE THE PRECIPITATION ENDS. THE EXCEPTION IS THE NORTHWEST ZONES WHERE THE MORE SOUTHERLY TRACK SUGGESTS MORE PRECIP WILL FALL IN SUBFREEZING AIR. DUE TO THE TERRAIN EFFECTS HERE...COLD AIR HAS AN EASY TIME GETTING INTO OUR NORTHWEST ZONES WHEN WE HAVE A NORTH/NORTHEAST SURFACE WIND. HAVE EXPANDED THE SNOW ADVISORY TO INCLUDE YOUNG/JACK/WISE COUNTIES...AND HAVE INCREASED SNOW TOTALS TO THE 2-4 INCH RANGE FROM BOWIE TO SHERMAN. THE NORTHEAST ZONES LIKELY WONT SWITCH TO SNOW UNTIL LATE AFTERNOON...AS COLD AIR WILL HAVE TROUBLE MOVING IN AT THE SURFACE DUE TO THE LEE SHADOW WARMING EFFECT OF THE OZARK PLATEAU. MOST OF THE SNOW THAT OCCURS THERE WILL BE AFTER 6 PM AND WILL BE HIGHLY DEPENDENT ON WHETHER MESOSCALE BANDING CAN SET UP IN THE WAKE OF THE UPPER LOW. THE NEW NAM HAS FINALLY FORECAST SOME SIGNIFICANT BANDING TO OCCUR...THUS WILL LEAVE THE ADVISORY ALONE IN THIS AREA...BUT CONFIDENCE IS A LITTLE LOWER IN THE NORTHEAST ZONES FOR 2+ INCHES OF SNOW. FARTHER TO THE SOUTH OF THE ADVISORY...FOR THE I-20 CORRIDOR AND INCLUDING THE METROPLEX...THERE IS NOW HIGH CONFIDENCE THAT SNOW WILL OCCUR. HOWEVER ALL INDICATIONS ARE THAT IT WILL STILL BE A BRIEF 1-3 HOUR EVENT WITH NOT ENOUGH TIME TO GET ACCUMULATIONS OVER AN INCH. IT MUST BE STRESSED THAT WITH TEMPERATURES FALLING INTO THE 20S BY SUNSET...ANY APPRECIABLE MOISTURE REMAINING ON BRIDGES...OVERPASSES AND EVEN SURFACE STREETS WILL LIKELY RE- FREEZE INTO BLACK ICE. ALTHOUGH WE ARE USING 1+ INCH AS CRITERIA FOR THE COUNTIES IN THE WINTER WEATHER ADVISORY AREA...WE MAY EXPAND THE ADVISORY SOUTH INTO THE METROPLEX OVERNIGHT DUE SOLELY TO TRAVEL IMPACTS. FINALLY CONCERNING THE SEVERE WEATHER THREAT. WITH A MORE SOUTHERLY TRACK OF THE UPPER LOW...THIS MEANS THERE IS LESS OF A CHANCE OF THE WARM FRONT MAKING IT INTO THE SOUTHEAST CWA TONIGHT AS IT WILL LIKELY STAY SOUTHEAST OF THE AREA. ELEVATED THUNDERSTORMS ARE STILL EXPECTED TO RAPIDLY INCREASE IN COVERAGE AFTER 3 AM...WITH ELEVATED INSTABILITY HIGH ENOUGH FOR A FEW SEVERE HAIL STORMS SOUTH OF I-20. HAVE TONED DOWN THE DAMAGING WIND AND TORNADO THREAT FROM OUR PRODUCTS...BUT WE WILL CONTINUE TO ADVERTISE HAIL STORMS POSSIBLE LATE TONIGHT AND EARLY TOMORROW MORNING. TR.92 && .PREV DISCUSSION... /ISSUED 301 PM CST MON DEC 24 2012/ OUR CHRISTMAS DAY/NIGHT WINTER STORM IS TAKING SHAPE OVER THE INTERIOR WEST THIS AFTERNOON. IT WILL MOVE SOUTHEAST OVERNIGHT AND SHOULD DEVELOP A CLOSED CIRCULATION AS IT ENTERS THE SOUTHWESTERN PANHANDLE BY DAYBREAK CHRISTMAS. ALTHOUGH TODAY/S MODEL SOLUTIONS CONTINUE TO SHOW SLIGHT TIMING AND TRACKING DIFFERENCES...THE AGREEMENT AND CONSENSUS BETWEEN THE GFS AND THE ECMWF HAVE BEEN AND CONTINUE TO BE THE PREFERRED SOLUTION FOR THIS STORM. THE 500MB CENTER SHOULD TRACK ALONG I-20 BETWEEN ABILENE AND DFW THEN JUST SOUTH OF I-30 FROM DFW TO TEXARKANA. IF THE TRACK IS 30 MILES SOUTH OR NORTH OF OUR FORECAST THEN IMPACTS WILL ALSO SHIFT ACCORDINGLY. LAST NIGHTS FRONT IS LOCATED FROM NORTH OF HOUSTON TO NEAR SAN ANTONIO TO AROUND FORT STOCKTON. SURFACE CYCLOGENESIS WILL BEGIN OVERNIGHT ALONG THIS FRONT AND TRACK EAST ALONG THE FRONT. WE ARE EXPECTING A WARM FRONT TO LIFT THROUGH THE SOUTHERN AND SOUTHEAST COUNTIES LATE TONIGHT AND THROUGH THE EAST-CENTRAL COUNTIES EARLY CHRISTMAS MORNING AS THE SURFACE LOW SLIDES EAST. CONVECTION WILL BEGIN OVERNIGHT AS THE ELEVATED WARM FRONT PUSHES NORTHWARD. STRONG UPPER DYNAMICS AND MID LEVEL INSTABILITY WILL LEAD TO SOME STRONG TO SEVERE THUNDERSTORMS BEFORE AND AFTER DAYBREAK. HAIL WILL BE THE MAIN THREAT BUT DAMAGING WIND CAN BE EXPECTED ALONG AND SOUTH OF THE SURFACE BOUNDARY. AS FOR TORNADOES...STORMS MOVING OVER THE SURFACE BOUNDARY WILL EXPERIENCE AN INCREASE IN STORM-RELATIVE HELICITY AND BRIEF TORNADOES ARE POSSIBLE. THE SEVERE WEATHER THREAT SHOULD MOVE INTO EAST TEXAS BY LATE MORNING. COLD ARCTIC AIR HAS BEEN BUILDING OVER THE NORTHERN AND CENTRAL PLAINS AND WILL SURGE INTO NORTH TEXAS BEHIND THE EXITING SURFACE LOW. THIS WILL RESULT IN RAIN TRANSITIONING TO SNOW WEST TO EAST ALONG AND NORTH OF I-20 FROM LATE MORNING (NW) THROUGH MID AFTERNOON (NE). WE STILL EXPECT 1-3 INCHES OVER THE NORTHERN TWO ROWS OF COUNTIES WITH THE HIGHEST AMOUNTS GENERALLY EAST OF A SHERMAN TO GREENVILLE LINE. WOULD NOT BE SURPRISED IF A BAND OF HEAVIER SNOW OCCURRED OVER THE NORTHEAST COUNTIES AROUND PARIS WHERE THE 700MB FRONTOGENESIS IS MORE LIKELY TO ENHANCE THE WRAP-AROUND BANDING. THE SNOW IS EXPECTED TO END OVER THE NORTHEAST BY MIDNIGHT. SNOW ACROSS OKLAHOMA AND WESTERN ARKANSAS COULD TOTAL 4-8 INCHES...AND TRAVEL NORTH OF THE RED RIVER OR INTO WESTERN ARKANSAS WILL BE TREACHEROUS CHRISTMAS DAY THROUGH WEDNESDAY. A WIND ADVISORY WILL BE NEEDED CHRISTMAS AFTERNOON AND NIGHT AS NORTH WINDS BLOW 20-30 MPH WITH GUSTS TO 40MPH. BLOWING SNOW WILL BE POSSIBLE IN THE AFTERNOON AND OVERNIGHT HOURS WHERE SNOW HAS OCCURRED. IT WILL BE BITTERLY COLD ON CHRISTMAS NIGHT WITH WIND CHILLS IN THE LOWER SINGLE DIGITS AND TEENS. ALSO ANY MOISTURE REMAINING ON ROADWAYS CHRISTMAS EVENING WILL FREEZE OVERNIGHT SO WEDNESDAY MORNING COMMUTERS NEED TO BE ALERT FOR ICY SPOTS. COLD AND DRY FOR WEDNESDAY. TEMPERATURES MODERATE ON THURSDAY AS WINDS RETURN SOUTH. ANOTHER COLD FRONT WILL MOVE THROUGH THE REGION FRIDAY WITH A CHANCE OF SHOWERS OVER THE CENTRAL AND EASTERN COUNTIES. TEMPERATURES BEHIND THIS FRONT WILL NOT BE AS COLD...BUT WILL KEEP HIGHS/LOWS BELOW NORMAL OVER THE WEEKEND. 75 && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
