...SYNOPSIS...
A MID LEVEL SHORTWAVE TROUGH /NOW EMERGING OVER THE SRN HIGH PLAINS/
WILL EJECT NEWD TO THE MID MS VALLEY BY LATE TODAY AND THE OH VALLEY
OVERNIGHT...IN RESPONSE TO A STRONGER TROUGH THAT WILL MOVE EWD OVER
EXTREME SRN CA/AZ AND ADJACENT NW MEXICO.  A COASTAL TROUGH/WARM
FRONT JUST OFF THE TX/LA COASTS WILL MOVE INLAND TODAY AND TONIGHT
IN CONJUNCTION WITH THE INITIAL SHORTWAVE TROUGH...AND BOUNDARY
LAYER DEWPOINTS INTO THE 60S WILL SPREAD NWD ACROSS THE NW GULF
COAST AND LOWER MS VALLEY.  DESPITE THIS LOW-LEVEL MOISTURE INCREASE
AND RESULTANT DESTABILIZATION...THE MAJORITY OF CONVECTION WILL
LIKELY BE ELEVATED ACROSS THE MS/TN VALLEY LATER TODAY AND
TONIGHT...N/NE OF THE SURFACE WARM SECTOR.  THEREFORE...EXPECT THE
SEVERE STORM THREAT TO REMAIN MINIMAL WITHIN THE DEVELOPING WARM
SECTOR ACROSS SE TX AND SRN LA.

LATER TONIGHT...ASCENT WILL LIKELY INCREASE OVER W CENTRAL/CENTRAL
TX IN ADVANCE OF THE SECOND MID LEVEL TROUGH.  CONDITIONALLY
UNSTABLE LAPSE RATES IN THE LOW-MID LEVELS AND INCREASING MOISTURE
WITH TIME WILL LIKELY SUPPORT THE DEVELOPMENT OF ELEVATED
THUNDERSTORMS. 

ELSEWHERE...A PRONOUNCED MID LEVEL COLD POOL WITH STEEP LAPSE RATES
/AS EVIDENCED BY SEVERAL LIGHTNING STRIKES W AND SW OF LAX/ SHOULD
SUPPORT AT LEAST ISOLATED THUNDERSTORMS TODAY NEAR THE SRN CA
COAST...AND EARLY TONIGHT INTO SW AZ ALONG THE PATH OF THE MID LEVEL
TROUGH.
