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 Feb 21, 5:35 AM CST, 2 hours 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE FORT WORTH TX 535 AM CST SUN FEB 21 2010 .AVIATION... SHOWERS AFFECTING THE METROPLEX TAF SITES AT THIS TIME WILL CONTINUE THROUGH ABOUT 9 OR 10 AM CST. ALSO EXPECT THUNDERSTORMS IN THE VICINITY OF METROPLEX NEXT FEW HOURS AS STRONG UPWARD VERTICAL MOTION FIELD APPROACHES FROM WEST AND INTERACTS WITH PRE-FRONTAL TROUGH. SOME LIGHT RAIN OR DRIZZLE POSSIBLE AROUND KACT THIS MORNING...WITH LIFR CONDITIONS PREVAILING THERE UNTIL 10 AM CST. DRIER AIR AND RAPIDLY IMPROVING CEILINGS WILL WORK INTO ALL TAF SITES LATER THIS MORNING AND THIS AFTERNOON AS VEERING LOW LEVEL WINDS BRING DRIER AIR FROM THE WEST. SOUTHWEST WINDS EARLY THIS AFTERNOON WILL BECOME NORTHWESTERLY AT 16 KTS WITH FROPA BY MID TO LATE AFTERNOON IN METROPLEX. SOME GUSTS OVER 25 KTS POSSIBLE INTO THE EARLY EVENING HOURS. FROPA AT KACT EXPECTED BY 6 PM WITH NNW15G22KT FORECAST THIS EVENING. 09 && .PREV DISCUSSION... /ISSUED 450 AM CST SUN FEB 21 2010/ WATER VAPOR DEPICTS UPPER LEVEL SHORTWAVE TROUGH RAPIDLY MOVING INTO THE TEXAS PANHANDLE EARLY THIS MORNING AND IT WILL CONTINUE EASTWARD ACROSS OKLAHOMA TODAY. FORCING AHEAD OF THE SYSTEM IS RESULTING IN A LINE OF PRIMARILY ELEVATED STORMS TO THE WEST OF THE CWA. CONVECTION WILL CONTINUE TO DEVELOP/PROGRESS EASTWARD THROUGH THE CWA THIS MORNING. MUCAPE VALUES OF 500-750 J/KG OVER NORTH TEXAS AND SUFFICIENT DEEP LAYER SHEAR VALUES MEANS THERE IS A POTENTIAL FOR SOME SMALL HAIL. HIGHEST POPS WILL BE PLACED OVER THE NORTHERN CWA...CLOSER TO THE TRACK OF THE SHORTWAVE AND BEST DYNAMIC LIFT. EXPECT THE CONVECTION TO CLEAR THE CWA FROM WEST TO EAST DURING THE MORNING HOURS...WITH DRIER SOUTHWEST WINDS IN THE LOW-MID LEVELS RESULTING IN SUNNY SKIES THIS AFTERNOON. A COLD FRONT...CURRENTLY STALLED ACROSS CENTRAL OKLAHOMA...WILL BEGIN TO DROP SOUTH INTO THE CWA THIS AFTERNOON. CANT RULE OUT A FEW SHOWERS/STORMS ALONG THE FRONT THIS AFTERNOON OVER THE EAST...BUT LARGE SCALE SUBSIDENCE WILL DOMINATE IN THE WAKE OF THE MORNING SHORTWAVE. NORTHERLY WINDS WILL BRING COOLER TEMPERATURES TO THE REGION TONIGHT WITH LOWS FALLING INTO THE 30S AREA WIDE. THE COOL WEATHER WILL CONTINUE INTO MONDAY WITH INCREASING CLOUDS AHEAD OF THE NEXT UPPER SYSTEM. THE PRIMARY FORECAST CHALLENGE IS THE POTENTIAL FOR ANOTHER ROUND OF SNOW ON TUESDAY. THANKFULLY MODELS ARE IN GOOD AGREEMENT NOW WITH THE EVOLUTION OF THE LARGE SCALE MID-UPPER LEVEL FEATURES... WITH ALL MODELS FOLLOWING THE LEAD SET BY THE GFS/ECMWF SOLUTIONS OF A COUPLE DAYS AGO. UPPER LEVEL BLOCKING HIGH OVER BRITISH COLUMBIA WILL BREAK DOWN AND THE RESIDUAL RIDGE AXIS WILL TRANSLATE SOUTHEAST INTO THE INTER-MOUNTAIN WEST BY TUESDAY. MEANWHILE THE UPPER TROUGH AXIS AND REGION OF POTENTIAL VORTICITY CURRENTLY LOCATED OVER IDAHO AND OREGON WILL PIVOT SOUTHEAST INTO TEXAS BY TUESDAY. THE PATTERN REALIGNMENT WILL HELP INTENSIFY NORTHERLY FLOW ALOFT OVER THE PLAINS...AND DRIVE COLDER AIR PRIMARILY IN THE MID-UPPER LEVELS SOUTHWARD INTO TEXAS TUESDAY. 500 MB TEMPS OVER NORTH TEXAS TUESDAY AFTERNOON WILL BE NEAR -24C WITH -4C AT 850MB. PRECIP MAY START AS RAIN OVER THE SOUTHERN COUNTIES BUT SHOULD TRANSITION TO ALL SNOW PRETTY QUICKLY. ALTHOUGH MODELS SHOW SURFACE TEMPS AOA FREEZING TUESDAY...WE THINK THESE WILL DROP TO 30-32 DEGREES WHEN IT IS SNOWING DUE IN PART TO THESE COLD TEMPS ALOFT. ALL IN ALL...WE ARE NOT CONCERNED ABOUT WARM TEMPS WITH THIS EVENT...AS IT SHOULD BE PLENTY COLD ENOUGH FOR A PRECIP TYPE AS ALL SNOW. THE TRACK OF THE SHORTWAVE AND POSITIONING OF THE 700 MB FRONT CONTINUES TO SUGGEST THAT THE SOUTHERN HALF OF THE CWA WILL BE THE FAVORED REGION FOR SNOW ACCUMULATIONS. ALTHOUGH LIGHT SNOW SHOULD BEGIN LATE MONDAY NIGHT ACROSS THE NORTHWEST/NORTH CWA...SPREADING EAST INTO THE METROPLEX BY DAYBREAK TUESDAY...THE SOUTHWARD ADVANCING 700 MB FRONT SHOULD END SNOW FROM NORTH TO SOUTH TUESDAY MORNING. SNOW WILL BE HEAVIEST DURING THE DAYLIGHT HOURS ACROSS THE SOUTHERN COUNTIES...AS THE SYSTEM SHOULD BE ABLE TO DRAW UP SOME BETTER QUALITY GULF MOISTURE...RESULTING IN SOME ELEVATED INSTABILITY WITH PARCELS LIFTED NEAR 700 MB. OF NOTE...THE 12KM NAM IS MODELING FRONTOGENETIC FORCING AND BANDED PRECIPITATION. AT THIS POINT...IT IS IMPOSSIBLE TO DETERMINE WHERE THESE BANDS WILL SET UP...BUT THE PRESENCE OF THIS TYPE OF MESOSCALE FORCING AND CONVECTIVE INSTABILITY WILL ALLOW FOR SOME LOCALLY HIGHER SNOWFALL TOTALS. WILL FORECAST 2-3 INCHES OF ACCUMULATION SOUTH OF A CISCO TO HILLSBORO TO ATHENS LINE...WITH A BAND NEAR AN INCH RUNNING FROM JACKSBORO TO DFW TO CANTON. JUST MINOR ACCUMULATIONS ARE FORECAST OVER THE NORTHEAST COUNTIES. NO WATCHES WILL BE ISSUED AT THIS TIME...AS WE ARE STILL SHORT OF THE 4 INCH IN 12 HOURS CRITERIA AND STILL A FEW DAYS AWAY. THIS DOES NOT MEAN THAT 4 INCHES IS NOT POSSIBLE...JUST THE CONFIDENCE OF 4 INCHES OR MORE IS STILL LESS THAN 50 PERCENT. SNOW SHOULD CLEAR THE AREA TUESDAY EVENING...WITH CLEARING SKIES ALLOWING FOR SUB-FREEZING TEMPS AREA WIDE WEDNESDAY MORNING. A WARM-UP WILL ENSUE BY MID WEEK WITH ANOTHER SYSTEM MOVING INTO THE REGION FRIDAY. GFS SEEMS TO BE WAY TOO AGGRESSIVE WITH MOISTURE RETURN AHEAD OF THE FRIDAY SYSTEM...AND HAVE SIDED WITH THE MUCH DRIER ECMWF/CANADIAN FORECASTS FRIDAY. TR.92 && .PRELIMINARY POINT TEMPS/POPS...
