VALID 260100Z - 261200Z
...NO TSTM AREAS FORECAST...
...FLORIDA...
SURFACE FRONT HAS PROGRESSED SOUTH/EAST OF THE SOUTHERN PENINSULA
AND KEYS. IN ITS WAKE...STABILIZATION ASSOCIATED WITH LOW-LEVEL
COOLING/DRYING HAS ENDED RISK FOR THUNDERSTORM ACTIVITY. AND...
FRONT WILL CONTINUE TO ADVANCE INTO/THROUGH THE BAHAMAS AND
CARIBBEAN OVERNIGHT...AS SURFACE CYCLOGENESIS PROCEEDS ACROSS THE
NORTHWEST ATLANTIC.
...SOUTHERN PLATEAU/ROCKIES AND RIO GRANDE VALLEY...
A FEW THUNDERSTORMS ARE OCCURRING BENEATH MID-LEVEL COLD CORE OF
CLOSED LOW OVER THE NORTHWESTERN MEXICAN PLATEAU. MODELS INDICATE
THAT THE GREAT BASIN RIDGE WILL CONTINUE TO WEAKEN OVERNIGHT...AND
UPPER CIRCULATION MAY BEGIN TO SLOWLY ACCELERATE NORTHEASTWARD.
THIS MAY BE ACCOMPANIED BY AN INCREASE IN SHOWERS ACROSS PARTS OF
SOUTHWEST TEXAS/SOUTHERN NEW MEXICO AND SOUTHEAST ARIZONA.
BUT...POTENTIAL FOR DESTABILIZATION AND DEVELOPMENT OF THERMODYNAMIC
STRUCTURE FAVORABLE FOR THUNDERSTORMS STILL SEEMS
NEGLIGIBLE...PARTICULARLY GIVEN LOSS OF DAYTIME HEATING.
FARTHER SOUTH/EAST...MID-LEVEL WARM ADVECTION/MOISTURE RETURN MAY
COMMENCE LATE TONIGHT ACROSS THE LOWER RIO GRANDE VALLEY. HOWEVER
...IT STILL APPEARS ANY THUNDERSTORM ACTIVITY WILL REMAIN WELL TO
THE SOUTH/SOUTHWEST OF BROWNSVILLE AND LAREDO THROUGH AT LEAST
26/12Z.
