THE SEVERE WEATHER THREAT FOR TORNADO WATCH 170, 177 CONTINUES.
SUMMARY...MULTIPLE CLUSTERS OF THUNDERSTORMS WILL TRACK INTO WESTERN
AR THIS EVENING, WITH COVERAGE OF OTHER STORMS INCREASING TOWARD
SUNSET.
DISCUSSION...THREE DISTINCT CLUSTERS OF SEVERE/SUPERCELL STORMS ARE
PRESENT THIS AFTERNOON OVER OK/AR. ONE IS SOUTHEAST OF FYV, ONE
NEAR FSM, AND A THIRD NEAR IDA. THESE STORMS WILL TRACK EASTWARD
FOR SEVERAL MORE HOURS INTO A VERY MOIST AND MODERATELY UNSTABLE AIR
MASS. FORECAST SOUNDINGS AND THE LZK VAD PROFILE SUGGEST SUFFICIENT
LOW-LEVEL AND DEEP-LAYER SHEAR FOR CONTINUED SUPERCELL STORM
STRUCTURES AND A RISK OF ALL SEVERE MODES. THE LOW-LEVEL JET IS
EXPECTED TO STRENGTHEN THIS EVENING AROUND DUSK, RESULTING IN
INCREASED COVERAGE OF STORMS, AND INCREASING THE RISK OF A FEW
TORNADOES.
NEW TORNADO WATCH #177 HAS JUST BEEN ISSUED FOR THIS AREA UNTIL 06Z.
