...DISCUSSION...
WITH A MARITIME TROPICAL AIR MASS RELEGATED TO THE
CARIBBEAN...NEGLIGIBLE SEVERE POTENTIAL WILL CONTINUE INTO MID-WEEK.
BY DAY 7-8...AIR MASS MODIFICATION WILL OCCUR ACROSS THE WRN GULF
WITH A LONGWAVE TROUGH AMPLIFYING OVER THE WRN CONUS. POLEWARD
MOISTURE TRANSPORT SHOULD YIELD WEAK BUOYANCY DEVELOPING FROM THE
WRN GULF COAST TOWARDS THE MID-SOUTH. ALTHOUGH LOW PREDICTABILITY
EXISTS WITH THE SUBSEQUENT EVOLUTION OF INDIVIDUAL SHORTWAVE
IMPULSES...A RELATIVELY STRONG COLD FRONT SHOULD PUSH SEWD TOWARDS
THE CNTRL CONUS. OVERALL PATTERN APPEARS ONLY MARGINALLY FAVORABLE
FOR SEVERE STORMS ATTM.
