CONCERNING...TORNADO WATCH 653...
VALID 110244Z - 110445Z
CORRECTED FOR WIND GUST TIME
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 653 CONTINUES.
CELLS HAVE BEGUN TO MERGE INTO QUASILINEAR STRUCTURES OVER THE PAST
HOUR OR SO...SUGGESTING A DECREASING TORNADO THREAT. HOWEVER...GIVEN
VERY STRONG INSTABILITY AND MOISTURE PROFILES...ESPECIALLY OVER NERN
OK AND SERN KS...MARGINAL LOW LEVEL SHEAR MAY BE SUFFICIENT FOR
CELLULAR ACTIVITY TO PRODUCE BRIEF TORNADOES. OVERALL...THE MAIN
THREAT WILL CONTINUE TO BE DAMAGING WIND GUSTS...AND HEAVY RAIN. A
WIND OF GUST OF 68 MPH WAS JUST RECORDED AT EMPORIA KS AT 0234Z.
HEAVY RAIN IS LIKELY TO PERSIST NEAR THE WARM FRONT WHERE ISENTROPIC
LIFT WILL PERSIST...UNTIL THE PRIMARY COLD FRONT AND/OR STRONG
OUTFLOW PUSHES THROUGH THE AREA. FARTHER S...THE LINE OF STORMS
ALONG THE KS TURNPIKE SHOULD PERSIST WITH A DAMAGING WIND
THREAT...AND THIS ACTIVITY COULD DEVELOP FARTHER S INTO OK AS THE
COLD FRONT CONTINUES TO PUSH SWD.
