Area forecast discussion, Jun 21, 11:20 AM CST, 1 hour 54 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 1220 PM CDT MON JUN 21 2004 .AVIATION... THE OUTFLOW FROM OVERNIGHT THUNDERSTORMS ACROSS OKLAHOMA...HAS PROVIDED A FOCUS FOR THUNDERSTORM DEVELOPMENT EARLY THIS AFTERNOON ACROSS THE AREA NORTH OF A JACKSBORO...TO SHERMAN...PARIS LINE. THIS ACTIVITY IS EXPECTED TO MOVE CLOSE TO...BUT MAYBE JUST BARELY NORTH OF THE METROPLEX AIRPORTS LATE THIS AFTERNOON. WILL INTRODUCE VCTS FOR THE AREA AIRPORTS FOR THE 20 TO 24Z TIME PERIOD...BUT WILL HAVE TO UPDATE LATER...IF THIS ACTIVITY LOOKS LIKE IT WILL ACTUALLY HIT THE AIRPORTS. OTHERWISE...A MESOSCALE CONVECTIVE COMPLEX...IS EXPECTED TO MOVE SOUTHEASTWARD INTO THE METROPLEX TUESDAY MORNING...THUS HAVE PLACED A TEMPO TSRA BETWEEN 12 AND 15Z. SOME STRATUS MAY MOVE INTO THE WACO AREA AFTER 09Z. #58 && .DISCUSSION... 1135 AM CDT MON JUN 21 2004 REMAINS OF THUNDERSTORM COMPLEX SAGGING SOUTH TO THE RED RIVER COUNTIES AT THE MOMENT. HAVE BUMPED THE POPS SLIGHTLY FOR THIS AFTERNOON FOR THE TOP TWO ROWS OF COUNTIES FOR SAME. MORNING SOUNDING SHOWED A VERY UNSTABLE ATMOSPHERE. AWAY FROM THE THUNDERSTORMS ALONG THE RED RIVER...THE MAIN CONCERN WILL BE IF ANY THUNDERSTORMS DEVELOP THIS AFTERNOON THEY WILL QUICKLY BECOME SEVERE WITH HAIL AND DOWNBURST WIND THE MAIN PROBLEM. 82 && .PREV DISCUSSION... 403 AM CDT MON JUN 21 2004 AN ACTIVE EARLY SUMMER PATTERN WILL REMAIN IN PLACE THE NEXT SEVERAL DAYS WITH A STRONG RIDGE ACROSS THE WEST COAST AND A LARGE SCALE TROUGH ACROSS THE CENTRAL AND EASTERN U.S. EXPECT SEVERAL ROUNDS OF THUNDERSTORMS THIS WEEK. MCS CURRENTLY MOVING SOUTHEAST ACROSS OKLAHOMA SHOULD BEGIN TO WEAKEN AS STORMS APPROACH THE RED RIVER COUNTIES. A FEW STORMS MAY HOLD TOGETHER...ESPECIALLY ACROSS FANNING AND LAMAR COUNTIES...THEREFORE...WILL PUT SOME POPS IN THIS MORNING. ALSO...A COMPLEX OF STORMS OVER SOUTHWEST TEXAS ASSOCIATED WITH A SHORT WAVE WILL CONTINUE TO PROPAGATE NORTHEAST AND REACH THE WESTERN COUNTIES THIS MORNING. AGAIN STORMS SHOULD WEAKEN THROUGH THE MORNING BUT A FEW NORTH TEXAS LOCATIONS COULD RECEIVE MEASURABLE RAIN. THE REMAINDER OF NORTH TEXAS SHOULD STAY DRY THIS MORNING... HOWEVER...OUTFLOW BOUNDARIES FROM THIS MORNING CONVECTION COULD ACT AS A FOCUS FOR AFTERNOON AND EVENING THUNDERSTORMS. ONE LIMITING FACTOR WILL BE A CAP OF WARM AIR...BUT LOW LEVEL MOISTURE AND MID LEVEL INSTABILITY WILL REMAIN HIGH...SO IF ANY STORM CAN GET GOING THEY COULD BECOME SEVERE. RAIN CHANCES WILL INCREASE LATE TONIGHT/TUESDAY MORNING AS A COLD FRONT AND MCS MOVES SOUTH ACROSS THE RED RIVER. THE FRONT IS FORECAST TO LIFT NORTHWARD ON WEDNESDAY AND BRING ANOTHER CHANCE OF THUNDERSTORMS. SCATTERED THUNDERSTORMS WILL BE POSSIBLE THROUGH THE WEEKEND AS SHORT WAVE ENERGY...MOVING THROUGH NORTHWEST FLOW ALOFT...INTERACTS WITH ABUNDANT LOW LEVEL MOISTURE. 79 && .PRELIMINARY POINT TEMPS/POPS...
