...ERN TX THROUGH LOWER MS VALLEY AND SERN U.S....

MID LEVEL JET ACCOMPANYING NRN STREAM IMPULSE WILL SHIFT EWD THROUGH
THE TN AND OH VALLEY AREA TUESDAY. A WSWLY LOW LEVEL JET COUPLED
WITH THE RIGHT ENTRANCE REGION OF UPPER JET WILL SHIFT EWD THROUGH
THE SERN STATES DURING THE DAY. COLD FRONT WILL CONTINUE TO SHIFT
SWD THROUGH THE SRN PLAINS AND SERN U.S IN WAKE OF THE NRN STREAM
IMPULSE. PARTIALLY MODIFIED GULF AIR WILL ADVECT NWD INTO THE
PRE-FRONTAL WARM SECTOR ACROSS PARTS OF SERN TX...SRN LA...MS AND
AL. POTENTIAL FOR CLOUDS TO PERSIST ACROSS THIS REGION AND WEAK MID
LEVEL LAPSE RATES SHOULD LIMIT INSTABILITY. CONVECTION WITH LITTLE
OR NO LIGHTNING WILL LIKELY BE ONGOING FROM NERN TX THROUGH THE
LOWER MS VALLEY INTO PARTS OF THE SERN U.S. IN ASSOCIATION WITH WARM
ADVECTION ACCOMPANYING THE WSWLY LOW LEVEL JET. AS THE PRE-FRONTAL
WARM SECTOR CONTINUES TO MOISTEN...POTENTIAL FOR THUNDERSTORMS TO
DEVELOP IN VICINITY OF THE FRONT MAY INCREASE...ESPECIALLY FROM THE
LOWER MS VALLEY INTO THE SERN STATES WHERE THE LOW LEVEL JET AND
CONVERGENCE SHOULD BE STRONGER.


...SWRN THROUGH S CNTRL TX...

PRESENCE OF STEEPER MID LEVEL LAPSE RATES AND INCREASING LARGE SCALE
ASCENT ASSOCIATED WITH EJECTING SRN STREAM IMPULSE MAY CONTRIBUTE TO
THE DEVELOPMENT OF CONVECTION OVER PARTS OF SWRN TX BY LATE TUESDAY
AFTERNOON OR EVENING. THIS ACTIVITY WILL LIKELY SPREAD EWD INTO THE
HILL COUNTRY OF S CNTRL TX TUESDAY NIGHT.
