VERY DYNAMIC...DEEPENING SITUATION DVLPG OVER THE CNTRL U.S. NEXT 
36 HRS AS STG SHRTWV INITIATES INTS SFC CYCLGN OVER THE MS VLY. 
SHRTWV IS CURRENTLY MOVG INTO W TX AND IS CAUSING REDVLPMT OF STG 
TSTMS FM NR MWL SWD TO W OF AUS AT 0630Z. THESE TSTMS XPCD TO BECOME  
SVR IN RESPONSE TO INCRG MID LVL PVA AND VRY FVRBL MID/UPR LVL  
DIFFLUENT PATTERN. VERY UNSTBL AMS PREVAILING ACRS MUCH OF ERN TX 
FURTHER SUPPORTS SVR TSTM/PSBL TORNADO DVLPMT OVER THIS RGN THRU  
THE MRNG HRS. THIS TSTM ACTVTY XPCD TO REMAIN SVR AS IT MOVES RPDLY 
ENEWD INTO AR/MS/LA AND WRN PTNS TN/AL DURG THE AFTN AND ERY EVE HRS. 
FAIRLY LRG 12 HR PRES FALLS ACRS THE WRN/CNTRL GLFMEX RGN INDICATE  
ANY REMAINING SFC RDGG IS QUICKLY ERODING. THIS PROCESS COMBINED WITH 
INCRG LOLVL SLY FLOW WILL ALLOW GULF MSTR/INSTBY TO RETURN RPDLY INTO 
THE LWR MS VLY AND CNTRL GULF CST RGN. VERY STG MID LVL WIND FIELDS 
WILL PROVIDE IMPRESSIVE VERT SHEAR PROFILE. THIS ALG WITH MID LVL DRY 
INTRUSION AND DIFFLUENT MID/UPR LVL FLOW SUGGEST CONTD THREAT FOR 
TORNADOES FM ERN TX INTO WRN AL INTO ERY TNGT. AS AFOREMENTIONED  
SHRTWV ROTS NEWD INTO THE MID MS VLY TNGT...XPC SVR TSTM ACTVTY TO  
BECOME MORE ISOLD AS SQLN MOVES FURTHER INTO THE TN VLY AND ERN GLF 
CST RGN TNGT. 
 
THERE IS ALSO A THREAT FOR ISOLD SVR TSTMS WITH STG WIND GUSTS ACRS 
THE MID/UPR MS VLY...THE OH VLY AND LWR GRTLKS RGN AS CNVTV OUTFLOW 
ENHANCES ALREADY STG LOLVL GRADIENT WINDS.
