AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SHREVEPORT LA 230 PM CST THU MAR 4 2004 .DISCUSSION... REGIONAL RADARS SHOW AN INTENSE SQUALL LINE MOVING THROUGH THE DALLAS METROPLEX TOWARD THE AREA. OUR AFTERNOON SURFACE ANALYSIS INDICATE TEMPS ACROSS AREA HAVE BEEN SLOW TO WARM UP...BUT A DRY SLOT OUT AHEAD OF THE UPPER LOW SHOULD HELP TEMPS A LITTLE DURING THE REMAINDER OF THE AFTERNOON. SEE PREVIOUS DISCUSSION FOR THIS AFTERNOON/S SEVERE WEATHER SOUNDING ANALYSIS. MODELS HAVE CONTINUED TO ERROR IN TRACKING THIS UPPER LOW THE LAST 24 HOURS...AS IT HAS CONTINUED TO TAKE A MORE SOUTHERN TRACK FROM THE PREVIOUS FORECAST. SPEED OF THE LOW HAS ALSO BEEN OFF BY THE MODELS...BUT THEY ALL HAVE ADJUSTED SOME BY SLOWING IT DOWN. CURRENT POSITION OF THE LOW IS JUST SOUTH OF EL PASO...WITH THE MODELS FORECASTING IT MOVING IT INTO NORTHERN KANSAS BY MIDNIGHT TONIGHT. SHOWERS AND THUNDERSTORMS ARE COMING...AND THE POTENTIAL FOR SEVERE WEATHER LOOKS PROMISING. THE ESTIMATED SQUALL LINE POSITION IS CURRENTLY NEAR A CLARKSVILLE...TYLER LINE BY 430 PM. THEN SLOWING DOWN AND REACHING THE LOUISIANA AND ARKANSAS BORDERS OF TEXAS BY 700 PM. AFTER THIS THINGS REALLY SLOW DOWN AND THE MODELS DO NOT HAVE PRECIPITATION EXITING NORTH CENTRAL LOUISIANA UNTIL FRIDAY AFTERNOON. AS A RESULT HEAVY RAIN WILL SET UP ACROSS...NORTHERN LOUISIANA...SOUTHERN ARKANSAS...AND DEEP EAST TEXAS TONIGHT...THUS I WILL ISSUE A FLOOD WATCH TO COINCIDE WITH THIS FORECAST. LATEST MCD INDICATES A TORNADO WATCH IS MOST LIKELY ON THE WAY FROM SPC...AS STORMS ARE HOLDING THEIR INTENSITY AS THEY CONTINUE MARCH TOWARD THE AREA. THINGS CLEAR OUT TOMORROW WITH DRY WEATHER THROUGH THE REST OF THE SHORT TERM AND EXTENDED FORECAST PACKAGE. WILL STAY CLOSE TO GFS MINS...THEN BALANCE BETWEEN GFS AND MOS ON MAXES.
