CONCERNING...TORNADO WATCH 22...
VALID 071224Z - 071400Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 22 CONTINUES.
SUMMARY...THE TORNADO AND LOCALIZED DAMAGING WIND THREAT MAY
CONTINUE THROUGH DAWN.
DISCUSSION...A LONG-LIVED SUPERCELL HAS RECENTLY PRODUCED AN
APPARENT TORNADO IN SOUTHWEST AR (NEVADA COUNTY). WHILE SOME
WEAKENING AND VEERING OF LOW-LEVEL FLOW HAS BEEN NOTED IN THE KSHV
AND KLZK VWPS, LOW-LEVEL SHEAR/SRH REMAINS MORE THAN SUFFICIENT FOR
TORNADO POTENTIAL WITH ANY SUSTAINED SUPERCELL, GIVEN THE PRESENCE
OF MODERATE BUOYANCY AND A SEASONABLY WARM/MOIST BOUNDARY LAYER.
ASIDE FROM THE TORNADIC SUPERCELL, OTHER STORMS ACROSS SOUTHWEST AR
HAVE BEEN RELATIVELY DISORGANIZED, THOUGH IT REMAINS POSSIBLE THAT
AN ADDITIONAL TORNADIC SUPERCELL MAY EVOLVE OUT OF CONVECTION WITHIN
THE PREFRONTAL WARM-ADVECTION REGIME.
FARTHER NORTHWEST, A COLD FRONT IS SURGING SOUTHEASTWARD ACROSS
WEST-CENTRAL/NORTHWEST AR. AS THIS FRONT IMPINGES UPON THE FAVORABLE
DOWNSTREAM ENVIRONMENT AND ONGOING WARM-SECTOR CONVECTION, AT LEAST
A BRIEF UPTICK IN DAMAGING-WIND AND BRIEF TORNADO POTENTIAL WILL BE
POSSIBLE ACROSS PARTS OF CENTRAL/NORTHERN AR, BEFORE THE THREAT ENDS
FROM NORTHWEST TO SOUTHEAST LATER THIS MORNING.
SOME SEVERE THREAT IS EXPECTED TO PERSIST BEYOND THE 14Z EXPIRATION
TIME OF WW 22. LOCAL WATCH EXTENSION AND/OR DOWNSTREAM WATCH
ISSUANCE IS POSSIBLE, DEPENDING ON SHORT-TERM TRENDS REGARDING
CONVECTIVE INTENSITY AND ORGANIZATION AS STORMS APPROACH
CENTRAL/EASTERN AR.
