VALID 081200Z - 091200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
A PROGRESSIVE BELT OF RELATIVELY STRONG WEST-SOUTHWESTERLY FLOW
ALOFT WILL CONTINUE TO ENCOMPASS ESPECIALLY THE NORTHERN HALF OF THE
CONUS THROUGH THE PERIOD. AN UPPER LOW CURRENTLY OVER NORTH MEXICO
WILL MIGRATE EAST-NORTHEASTWARD TOWARD THE SOUTHERN PLAINS...AND
SLOWLY COME MORE INTO PHASE WITH THE AFOREMENTIONED STRONGER
WESTERLIES. OTHERWISE...TROPICAL SYSTEM IDA MAY STRENGTHEN AS IT
CONTINUES NNW TOWARD THE SOUTHEAST GULF OF MEXICO...REFERENCE LATEST
NHC GUIDANCE FOR DETAILS. OVERALL POTENTIAL FOR SEVERE TSTMS IS VERY
LOW ACROSS THE LOWER 48 TODAY.

...SOUTH TX...
E-NE ADVANCING UPPER LOW OVER NORTHERN MEXICO AND A MODEST INCREASE
IN LOW LEVEL MOISTURE ACROSS SOUTH TX WILL CONTRIBUTE TO TSTM
POTENTIAL ACROSS THE SOUTHERN THIRD OF TX TODAY. WEAK MID LEVEL
LAPSE RATES/BUOYANCY WILL LIKELY PRECLUDE A SEVERE THREAT.

...PACIFIC NORTHWEST...
SOME TSTMS WILL REMAIN POSSIBLE AGAIN TODAY ALONG THE PACIFIC
NORTHWEST COAST AND ADJACENT OFFSHORE AREAS AHEAD OF A BROAD UPPER
TROUGH APPROACHING THE COAST OF BRITISH COLUMBIA.

...SOUTH CENTRAL PLAINS LATE TONIGHT...
SOME LATTER PERIOD TSTMS MAY OCCUR ACROSS THE SOUTH CENTRAL PLAINS
TONIGHT ALONG SE ADVANCING FRONTAL ZONE...MAINLY ACROSS PORTIONS OF
CENTRAL/EASTERN KS AND NORTHERN OK AFTER 06Z. WHILE SHOWERS MAY BE
DOMINANT...MODEL FORECAST SOUNDINGS REFLECT WEAK BUOYANCY/CHARGE
SEPARATION SUFFICIENT FOR THE POSSIBILITY OF SOME
EMBEDDED/OCCASIONAL TSTMS.
