...THERE IS A SLGT RISK OF SVR TSTMS FOR A SMALL PART OF THE RED
RIVER IN SW OK/NW TX THIS EVENING...

...SUMMARY...
A COUPLE OF SEVERE STORMS ALONG THE RED RIVER WITH LARGE HAIL AS THE
PRIMARY RISK SHOULD WEAKEN BY ABOUT 10-11 PM.

...SRN PLAINS...
A COUPLE OF SUPERCELLS ALONG THE RED RIVER IN SW OK/NW TX WILL POSE
THE GREATEST RISK FOR LARGE HAIL AND SEVERE WIND INTO LATE EVENING.
THIS ACTIVITY APPEARS TO BE FED BY A NARROW WEDGE OF MODESTLY
BUOYANT AIR MASS REMAINING OVER THE LOW ROLLING PLAINS OF NW TX.
STABILIZING EFFECTS OF DOWNSTREAM CONVECTION N/E OF THE I-35
CORRIDOR ARE PRONOUNCED IN 00Z OUN/FWD RAOBS.

BEYOND THIS LOCALIZED SEVERE AREA...OVERALL RISK IS QUITE MARGINAL.
A LONE DISCRETE STORM NEAR THE CONFLUENCE OF THE PECOS/RIO GRANDE
RIVERS SHOULD DISSIPATE SOON AMIDST MINIMAL LARGE-SCALE ASCENT AND
INCREASING MLCIN AFTER DARK. FARTHER N...SCATTERED TO NUMEROUS
STORMS HAVE BEEN AIDED BY ASCENT VIA A WEAK SRN STREAM SHORTWAVE
IMPULSE. THIS ACTIVITY SHOULD REMAIN SUB-SEVERE GIVEN A WEAK
COMBINATION OF SHEAR/BUOYANCY PER 00Z DDC/AMA RAOBS.
