...THERE IS A MRGL RISK OF SVR TSTMS ACROSS DEEP S TX...

...SUMMARY...
A FEW STRONG/ISOLATED SEVERE THUNDERSTORMS MAY OCCUR OVER SOUTH
TEXAS THURSDAY.

...SYNOPSIS...
BELT OF ENHANCED/LOW-AMPLITUDE WLYS WILL REMAIN ACROSS SRN CANADA
AND THE NRN U.S. THIS PERIOD...WITH A TROUGH FORECAST TO CROSS
ONTARIO AND QUEBEC...AND THE GREAT LAKES REGION THROUGH THE DAY.
SHOWERS AND SCATTERED THUNDERSTORMS WILL LIKELY OCCUR ALONG AN
ASSOCIATED COLD FRONT...TRAILING SWWD FROM AN ERN CANADA LOW ACROSS
THE LOWER GREAT LAKES/OH VALLEY REGION.  MEANWHILE FARTHER W...THE
WLYS ALOFT ACROSS THE HIGH PLAINS WILL SUPPORT A PERSISTENT SURFACE
LEE TROUGH OVER THE NRN AND CENTRAL HIGH PLAINS...WITH A SURFACE LOW
POSSIBLY DRIFTING EWD ACROSS SD ALONG A WEAK WARM FRONT DURING THE
SECOND HALF OF THE PERIOD.  FINALLY...A WEAK UPPER LOW WILL MOVE
SLOWLY EWD ACROSS THE SRN PLAINS THROUGH 03/12Z.

...S TX...
SCATTERED SHOWERS AND THUNDERSTORMS ARE FORECAST ACROSS THE SRN
PLAINS THU...AS A WEAK UPPER LOW DRIFTS SLOWLY ACROSS THE AREA.
GENERALLY WEAK FLOW ALOFT SURROUNDING THE LOW SUGGESTS MINIMAL
SEVERE RISK IN MOST AREAS.

ONE EXCEPTION TO THIS MAY BE ACROSS DEEP S TX...ON THE SERN FRINGE
OF THE UPPER CIRCULATION.  HERE...SLIGHTLY STRONGER WSWLY MID-LEVEL
FLOW IS EXPECTED ATOP LOW-LEVEL ESELYS...RESULTING IN SUFFICIENT
SHEAR FOR AT LEAST WEAKLY ORGANIZED UPDRAFTS.  THUS -- WILL MAINTAIN
LOW PROBABILITY /5%/ RISK FOR A BRIEFLY SEVERE STORM OR TWO DURING
THE AFTERNOON ACROSS THIS AREA.
