VALID 171758Z - 171930Z
TRENDS ARE BEING MONITORED FOR AN INCREASING SEVERE THREAT AND THE
POSSIBILITY OF A WW.
LOWER/MID TROPOSPHERIC CIRCULATION MAY BE IN THE PROCESS OF FORMING
TO THE NORTH/NORTHWEST OF HILL CITY KS. ASSOCIATED FORCING FOR
UPWARD VERTICAL MOTION WITH THIS FEATURE MAY AID CONVECTIVE
DEVELOPMENT BY 19-21Z...IN LOW-LEVEL WARM ADVECTION REGIME EAST OF
SURFACE DRY LINE. ADDITIONAL ISOLATED STORM DEVELOPMENT MAY FOLLOW
SUITE THEREAFTER...SOUTHWARD ALONG DRY LINE TOWARD MEDICINE LODGE.
A NARROW CORRIDOR OF MIXED LAYER CAPE UP TO AROUND 1000 J/KG IS
POSSIBLE ACROSS THIS REGION BY PEAK AFTERNOON HEATING. AND...DEEP
LAYER SHEAR BENEATH 30-50 KT SOUTH SOUTHWESTERLY 500 MB FLOW IS
SUFFICIENT FOR SUPERCELLS. LOW-LEVEL HODOGRAPHS MAY NOT BE
PARTICULARLY LARGE...BUT FAVORABLE AMBIENT VERTICAL VORTICITY AND
STEEP LOW-LEVEL LAPSE RATES PROBABLY WILL BE SUPPORTIVE OF AT LEAST
BRIEF TORNADOES...IN ADDITION TO THE RISK FOR LARGE HAIL/DAMAGING
WIND GUSTS.
