..DISCUSSION
 
 
A BROAD MID-LEVEL TROUGH WILL EJECT INTO THE ATLANTIC WHILE ANOTHER  
MID-LEVEL TROUGH GRADUALLY PROGRESSES ACROSS THE CONUS THIS UPCOMING  
WEEK INTO NEXT WEEKEND. A SURFACE LOW WILL RAPIDLY TRACK FROM THE  
SOUTHEAST GULF COAST, NORTHEASTWARD ALONG THE EASTERN SEABOARD DAY  
4/TUESDAY, SUPPORTING THUNDERSTORM DEVELOPMENT ALONG THE SOUTHEAST  
COAST AND THE FL PENINSULA. THEREAFTER, SURFACE HIGH PRESSURE AND  
ASSOCIATED STATIC STABILITY SHOULD LIMIT THUNDERSTORM DEVELOPMENT  
OVER MOST LOCALES UNTIL LATE IN THE WEEK INTO THE WEEKEND. BY THIS  
POINT, MOISTURE RETURN ACROSS THE WESTERN GULF COAST REGION MAY  
FOSTER ENOUGH BUOYANCY TO SUPPORT THUNDERSTORM POTENTIAL. IT IS  
PLAUSIBLE THAT STRONG TO PERHAPS ISOLATED SEVERE THUNDERSTORMS MAY  
DEVELOP OVER THE TX COASTAL PLAIN IN THE DAYS 6-7 (THURSDAY-FRIDAY)  
TIME FRAME IF THE MOISTURE CAN BECOME RICH/DEEP ENOUGH TO SUPPORT  
GREATER BUOYANCY. HOWEVER, THE LACK IN MEDIUM-RANGE GUIDANCE  
AGREEMENT LENDS TOO LITTLE CONFIDENCE IN THIS SCENARIO FOR THE  
INTRODUCTION OF SEVERE PROBABILITIES THIS FAR IN ADVANCE.
