...NO SVR TSTM AREAS FORECAST...

...LOWER MS/TN VALLEY AREA...
A MID LEVEL SHORTWAVE TROUGH OVER NE NM THIS MORNING WILL MOVE EWD
OVER OK TODAY AND THEN CONTINUE ENEWD ACROSS THE MID MS AND OH
VALLEYS OVERNIGHT.  AT THE SURFACE...A SHALLOW FRONT ACROSS S GA AND
THE IMMEDIATE N CENTRAL GULF COAST WILL MOVE INLAND/REFORM FARTHER N
ACROSS CENTRAL LA/MS/NRN AL BY LATE TODAY...S OF THE  ONGOING RAIN
BAND FROM NW LA TO MIDDLE TN.  A WEAK WAVE WILL LIKELY DEVELOP NEWD
ALONG THE SURFACE FRONT FROM SW LA TO CENTRAL MS BY LATE
AFTERNOON...AND THEN CONTINUE ENEWD TO THE CENTRAL APPALACHIANS BY
THE END OF THE PERIOD IN ASSOCIATION WITH THE SHORTWAVE TROUGH
CROSSING THE MID MS/OH VALLEY REGION OVERNIGHT.

AS THE WARM SECTOR SPREADS INLAND THROUGH ADVECTION AND VERTICAL
MIXING...THE LOW LEVELS WILL DESTABILIZE AND WEAK INSTABILITY IS
EXPECTED FOR PARCELS BASED NEAR OR JUST ABOVE THE GROUND.  THE MORE
PROBABLE AREA FOR THUNDERSTORMS THROUGH MIDDAY WILL BE INVOF THE
SABINE RIVER...AND CONVECTION SHOULD SPREAD NEWD INTO MS/AL/TN LATER
THIS AFTERNOON INTO TONIGHT.  WHILE VERTICAL SHEAR WILL BE
REASONABLY STRONG WITHIN THE WARM SECTOR...POOR LAPSE RATES AND
RELATIVELY WARM MID LEVEL TEMPERATURE PROFILES WILL LIMIT CAPE AND
ANY SEVERE STORM THREAT.

...PACIFIC COAST AREA...
A DEEP/COLD MID LEVEL TROUGH WILL MOVE SLOWLY SWD OFF THE WA/ORE
COASTS AS A SEPARATE WAVE JUST OFF THE CENTRAL CA COAST EJECTS EWD
AND LOSES AMPLITUDE.  SOME CONVECTION AND A FEW LIGHTNING STRIKES
MAY ACCOMPANY THE TROUGH MOVING OVER CENTRAL CA TODAY...WHILE
LOW-TOPPED THUNDERSTORMS ASSOCIATED WITH THE MID LEVEL COLD POOL MAY
SKIRT THE COAST FROM NW CA TO WA LATER TODAY INTO TONIGHT.
