THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 122
CONTINUES.

SUMMARY...STRONG TO ISOLATED SEVERE STORMS MAY PERSIST BEYOND
SCHEDULED EXPIRATION OF WW 122. WHETHER THE THREAT WILL BE
SUFFICIENT FOR A REPLACEMENT WW IS UNCLEAR...AND SPC WILL BE
CONTACTING AFFECTED WFOS ABOUT THE RISK BEYOND 11Z.

DISCUSSION...SCATTERED STORM CLUSTERS ARE ONGOING FROM NORTHWEST OK
SOUTHWEST TO THE TX S PLAINS. CONVECTION HAS STRUGGLED TO GREATLY
INTENSIFY BEYOND STRONG TO MARGINALLY SEVERE LEVELS IN SPITE OF
LARGE CYCLONIC HODOGRAPHS SAMPLED IN AMA/LBB VWP DATA NEAR/NORTH OF
THE SURFACE WARM FRONT THAT ARCS ACROSS EAST-CENTRAL NM TO NEAR LBB
AND EAST ACROSS NORTH TX. FARTHER SOUTH...A NORTH-SOUTH ORIENTED
CONVECTIVE BAND HAS DEVELOPED BETWEEN LBB/MAF WITHIN A MORE
FAVORABLE SURFACE-BASED ENVIRONMENT. THE 08Z HRRR SUGGESTS THIS
CONVECTION WILL BE RATHER SHORT-LIVED. WITH A CONDITIONALLY
SUPPORTIVE ENVIRONMENT FOR ORGANIZED STORMS...CONCERN EXISTS THAT AT
LEAST AN ISOLATED SEVERE THREAT MAY PERSIST INTO MID-MORNING.
