       NORTHEAST NEW MEXICO
       WESTERN OKLAHOMA
       TEXAS PANHANDLE

EFFECTIVE THIS FRIDAY AFTERNOON AND EVENING FROM 225 PM UNTIL

DO PRODUCE TORNADOES.

OTHER WATCH INFORMATION...CONTINUE...WW 332...WW 333...WW 334...

DISCUSSION...THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG A WEAK
FRONT/WIND SHIFT SPREADING SEWD FROM CO THIS AFTERNOON. ADDITIONAL
STORMS WILL LIKELY FORM ACROSS THE MOUNTAINS OF SERN CO AND NERN NM
AND TRACK SEWD. STRONG SURFACE HEATING AND MODEST LOW LEVEL MOISTURE
ALONG A RESIDUAL FRONT BACKED INTO THE SRN HIGH PLAINS WILL
CONTRIBUTE TO MODERATE INSTABILITY THAT SHOULD FUEL THE DEVELOPING
TSTMS. MID LEVEL FEATURES SUPPORTING STRONGER LARGE SCALE ASCENT
ACROSS THE REGION REMAIN NONDESCRIPT. HOWEVER...THE ENTIRE REGION
LIES BENEATH THE SWRN FLANK OF STRONGER NWLY MID LEVEL FLOW
WHICH...ATOP LOW LEVEL SLY FLOW...SHOULD RESULT IN EFFECTIVE SHEAR
AROUND 50KT. THUS KINEMATIC AND THERMODYNAMIC REGIME WILL BE MORE
THAN ADEQUATE FOR UPDRAFT PERSISTENCE AND ROTATION. PRIMARY SEVERE
IMPACTS SHOULD BE LARGE HAIL...PERHAPS A HAIL FEW REPORTS AOA 2
INCHES IN DIAMETER...AND LOCALLY DAMAGING WINDS. THERE IS A CHANCE
FOR A TORNADO OR TWO IF DISCRETE CELLS CAN DEVELOP NEAR/ALONG WIND
SHIFT/OUTFLOW SITUATED FROM WRN OK INTO SWRN KS WHERE LOW LEVEL
SHEAR WILL BE ENHANCED. PRESENT INDICATIONS ARE THAT LACK OF GREATER
LOW LEVEL MOISTURE AND THE POTENTIAL FOR OUTFLOW DOMINANT STORMS
SHOULD KEEP TORNADO POTENTIAL LIMITED.

AVIATION...A FEW SEVERE THUNDERSTORMS WITH HAIL SURFACE AND ALOFT
TO 2.5 INCHES. EXTREME TURBULENCE AND SURFACE WIND GUSTS TO 65
KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 500. MEAN STORM
MOTION VECTOR 33030.
