CORRECTED FOR MD GRAPHIC
SCT TSTMS ARE EXPECTED ALONG A STATIONARY FRONT EXTENDING FROM SWRN
KS INTO ECENTRAL KS. ISOLATED DMGG WIND GUSTS WILL BE POSSIBLE WITH
THE STRONGEST TSTMS...BUT A WW IS NOT EXPECTED.
LATEST VISIBLE SAT IMAGERY SHOWS MDT CU DEVELOPING ALONG A
STATIONARY BOUNDARY EXTENDING FROM AN AREA OF LOW PRESSURE NEAR
GARDEN CITY ENEWD TO NEAR HAYS AND THE EWD ALONG I-70 TO JUST SOUTH
OF TOPEKA. RELATIVELY WEAK CONVERGENCE ALONG THE BOUNDARY HAS
LIMITED CONVECTIVE DEVELOPMENT THUS FAR. HOWEVER...WEAKENING CINH
COMBINED WITH SOME CONVERGENCE ALONG THE BOUNDARY /MAXIMIZED INVOF
OF THE LOW IN SWRN KS AND WHERE BOUNDARY INTERSECTIONS WERE
OCCURRING NEAR SLN/ SHOULD SUPPORT SCT TSTM DEVELOPMENT OVER THE
AREA BY 23Z. RELATIVELY WEAK MID LEVEL WINDS /15 KTS OR LESS/ WILL
SUPPORT A MULTICELL CONVECTIVE MODE. STEEP LOW LEVEL LAPSE RATES AND
MODEST T/TD SPREADS MAY SUPPORT ISOLATED DMGG WIND GUSTS WITH THE
STRONGEST TSTMS GIVE MODERATE INSTABILITY /MLCAPE AROUND 2000 J/KG/.
ACTIVITY IS EXPECTED TO WEAKEN WITHIN AN HOUR AFTER SUNSET.
