A PERSISTENT NRN US UPPER-LEVEL TROUGH WILL CONTINUE AS ZONAL FLOW
REMAINS IN PLACE IN THE SRN US. SEVERAL IMPULSES ARE FORECAST TO
MOVE ENEWD IN THE SRN STREAM ACROSS TX INTO THE LOWER MS VALLEY BY
TUESDAY AND TUESDAY NIGHT. IN ADDITION...A COLD FRONT IS FORECAST TO
MOVE SWD INTO EAST TX EXTENDING ENEWD ACROSS NRN LA IN NRN MS.
FORECAST SOUNDINGS ALONG AND JUST AHEAD OF THE FRONT TUESDAY NIGHT
SHOW LIMITED INSTABILITY ALTHOUGH SFC DEWPOINTS MAY REACH THE 60S F
IN PARTS OF EAST TX AND LA. IF CONVERGENCE ALONG THE BOUNDARY AND
LARGE-SCALE ASCENT ASSOCIATED WITH AN APPROACHING SHORTWAVE CAN
INITIATE CONVECTION...A FEW THUNDERSTORMS WOULD BE POSSIBLE MAINLY
DURING THE OVERNIGHT PERIOD FROM EAST TX EXTENDING ENEWD TO NRN MS.
DUE TO THE WEAK INSTABILITY...ANY CONVECTION WOULD LIKELY BE
ELEVATED AND SUB-SEVERE. WILL NOT ISSUE A THUNDER OUTLOOK AREA ATTM
BECAUSE ANY STORMS THAT DEVELOP SHOULD REMAIN VERY ISOLATED.
