VALID 211200Z - 221200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...

MID AND UPPER LEVEL LOW CURRENTLY OVER NM IS FORECAST TO EVOLVE INTO
AN OPEN WAVE AND DEAMPLIFY AS IT LIFTS NEWD THROUGH THE CNTRL/SRN
PLAINS TODAY/TONIGHT AND INTO THE OH VALLEY SUNDAY.  AS THIS
OCCURS...DIGGING MID AND HIGH LEVEL JET STREAKS WILL CONTRIBUTE TO
THE FORMATION OF UPSTREAM CLOSED LOW OVER THE SWRN DESERTS.

IN THE LOW LEVELS...WEAKENING SURFACE LOW ATTENDANT TO DEAMPLIFYING
WAVE WILL DEVELOP NEWD FROM CNTRL KS OR NWRN OK INTO THE OH VALLEY
WITH TRAILING COLD FRONT PUSHING SWD THROUGH THE SRN PLAINS. 
MEANWHILE...SECONDARY LOW PRESSURE NOW OFF THE LOWER TX COAST WILL
DEVELOP NEWD THROUGH THE LOWER MS VALLEY INTO SRN APPALACHIANS WITH
TRAILING WEAK FRONT PUSHING EWD/SEWD THROUGH THE WRN/CNTRL GULF
COAST.

...GULF COAST...

SWLY LLJ /INDUCED BY WEAKENING WAVE LIFTING THROUGH THE OH VALLEY/
WILL SLOWLY MIGRATE EWD ACROSS THE REGION...SUPPORTING AN
INCREASINGLY MOIST AIR MASS AHEAD OF LOWER LATITUDE SURFACE LOW AND
ATTENDANT FRONT.  THIS MOISTENING COUPLED WITH PERSISTENT ISENTROPIC
ASCENT IS EXPECTED TO MAINTAIN A BAND OF SHOWERS WITH A FEW EMBEDDED
TSTMS WITHIN PRE-FRONTAL AIR MASS.

WHILE DEWPOINTS WILL INCREASE INTO THE LOW TO PERHAPS MID 60S ALONG
AND S OF THE I-10 CORRIDOR...LAPSE RATES AND RESULTANT INSTABILITY
WILL REMAIN QUITE WEAK.  THEREFORE...DESPITE THE MODERATELY STRONG
WIND FIELDS...NO SEVERE STORMS ARE FORECAST.
