NWS Amarillo, TX wrote its last area forecast discussion before the first event at Apr 11, 2:32 PM CST, 1 hour 20 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE AMARILLO TX 332 PM CDT SUN APR 11 2010 .DISCUSSION... A VERY UNSETTLED WEATHER PATTERN OVER THE NEXT SEVERAL DAYS. ATTM...SHOWERS AND UNORGANIZED TSTMS WERE DEVELOPING JUST SOUTH OF THE CWA BOUNDARY AND MOVING ENE IN RESPONSE TO A STATIONARY FRONT BISECTING THE PANHANDLES ALONG WITH WEAK UPPER LEVEL ENERGY MOVING ACROSS THE SOUTH PLAINS. MAY SEE SOME OF THIS ACTIVITY MOVE INTO THE SRN AND SE TX PANHANDLE THIS AFTN AND EVENING...BUT ONLY AN ISOLATED MARGINALLY SEVERE STORM OR TWO ARE ANTICIPATED AT BEST. BELIEVE MOST OF THE ACTIVITY WILL NOT BE SEVERE. MID LEVEL HIGH PRESSURE PARKED ACROSS THE SOUTHEAST WILL REMAIN VIRTUALLY STATIONARY FOR THE REMAINDER OF THE WEEK AND ALLOW FOR A MOIST SOUTH AND SE FLOW INTO THE AREA. A LARGE BROAD TROUGH WILL APPROACH THE PANHANDLES EARLY IN THE WEEK. AS THE UPPER TROUGH TRACKS NORTH OF THE AREA...A PAC COLD FRONT WILL APPROACH THE AREA MONDAY AND GENERATING SCATTERED THUNDERSTORMS ACROSS EASTERN NM MON AFTERNOON AND EVENING. SOME OF THESE STORMS WILL LIKELY PROPAGATE ACROSS THE AREA MONDAY NIGHT AND REDEVELOP TUESDAY AS THE PAC COLD FRONT ENTERS THE NW TEXAS PANHANDLE. A WEAK SOUTHWEST LY FLOW ALOFT PATTERN WILL SET THE STAGE FOR SEVERAL UPPER LEVEL SHORT WAVES TO AFFECT THE AREA THROUGH FRIDAY. THE EXACT TIMING AND STRENGTH OF THESE SYSTEMS WILL BE DIFFICULT TO DISCERN...BUT APPEARS A FAIRLY SIGNIFICANT DISTURBANCE WILL AFFECT THE AREA WED AND THU. WITH GENEROUS AMOUNTS OF LOW LEVEL MOISTURE IN PLACE...SHOWERS AND THUNDERSTORM CHANCES ARE INCREASING AND COULD PRODUCE BENEFICIAL RAINS ACROSS THE AREA. WIDESPREAD SEVERE WX IS NOT ANTICIPATED AT THIS TIME DUE TO WEAK SHEAR AND WEAK FORCING. A STRONGER SHORTWAVE SATURDAY COULD PROVIDE FOR MORE ORGANIZED STORMS ON SATURDAY AND A BETTER POTENTIAL TO BE SEVERE. LOTS OF CLOUDINESS AND LOW LEVEL MOISTURE...ALONG WITH THE POTENTIAL FOR SHOWERS AND STORMS WILL LIKELY TREND HIGH TEMPS DOWN OVER THE NEXT SEVERAL DAYS. MODELS ALREADY TRENDING THAT WAY AND WAS QUICK TO JUMP ON BOARD. NOT A LOT OF BIG TEMPERATURE SWINGS ANTICIPATED FOR THE NEXT SEVERAL DAYS WITH ALL COLD FRONTS LIKELY TO REMAIN NORTH OF THE AREA. THEREFORE...HELD VERY CLOSE TO MOS TEMPS AND LEFT EXTENDED PERIODS ALONE. && .FIRE WEATHER... MINIMAL FIRE WEATHER CONCERNS FOR THE NEXT SEVERAL DAYS. BREEZY TO WINDY CONDITIONS MAY OCCUR EARLY IN THE WEEK...BUT RELATIVE HUMIDITIES ARE EXPECTED TO REMAIN WELL ABOVE 30 PERCENT AND GENERALLY AT OR ABOVE 40 PERCENT DURING THE AFTERNOON HOURS AND 80 TO 100 PERCENT AROUND SUNRISE EACH DAY. THE POTENTIAL FOR SCATTERED SHOWERS AND THUNDERSTORMS WILL LIKELY CREATE WETTER SOIL CONDITIONS AS WELL OVER THE NEXT SEVERAL DAYS. && .PRELIMINARY POINT TEMPS/POPS...
