THEREFORE...THERE WILL BE SEVERAL CHANCES FOR THUNDERSTORMS THE NEXT FEW DAYS...SOME POSSIBLY SEVERE...AS SLOWING COLD FRONT IS FORECAST TO BECOME STATIONARY JUST SOUTH OF METROPLEX LATE TONIGHT...THEN BEGIN TO MOVE SLOWLY NORTHWARD TOMORROW AFTERNOON. MORNING STORMS ACROSS THE SOUTH HAVE RESULTED FROM DIFFERENTIAL HEATING AND STRONG INSTABILITY. AS COLD FRONT AND OUTFLOW BOUNDARIES INTERACT THIS AFTERNOON/EVENING...SEVERE THUNDERSTORMS WILL BE POSSIBLE...MAINLY ACROSS THE SOUTHEAST 2/3RDS TO 1/2 OF OUR CWA. HOWEVER...18Z SOUNDING STILL SHOWS A PRETTY GOOD CAP.

MOISTURE REMAINS SHALLOW...BUT STILL COULD SEE SOME STORMS BEAK THE CAP AND QUICKLY BECOME SEVERE. DRY LINE WILL ADD INTO THE MIX TOMORROW AFTERNOON AS MODELS SHOW A BULGE INTO N TEXAS NEAR THE FRONTAL BOUNDARY. NOT A LOT OF UPPER LEVEL SUPPORT INDICATED TOMORROW...AND CAP WILL ALSO BE A NEGATIVE FOR STORMS.

WARM FRONT SHOULD MOVE INTO OKLAHOMA ON SATURDAY...BUT SHORT RANGE MODELS AGAIN SHOW A PRETTY GOOD PUSH ON THE DRY LINE SATURDAY AFTERNOON. WHILE WE LOSE THE WARM FRONT...WILL WILL BEGIN TO BE INFLUENCED BY BETTER...ALTHOUGH WEAK...UPPER LEVEL DYNAMICS AS H5 TROUGH MOVES CLOSER TO N TEXAS. SEVERE THUNDERSTORMS SHOULD AGAIN BE POSSIBLE WITH THE DRY LINE SATURDAY AFTERNOON/EVENING. A COLD FRONT WILL FOLLOW THE DRY LINE BY SUNDAY MORNING AND THIS SHOULD ALLOW TEMPERATURES TO COOL CLOSER TO NORMALS FOR THE FIRST PART OF THE WEEK. THUNDERSTORM CHANCES WILL LINGER INTO NEXT WEEK...BUT THESE SHOULD BE MAINLY LATE AFTERNOON/EVENING STORMS AS H5 FLOW BECOMES MORE ZONAL.
