   CONCERNING...TORNADO WATCH 194...
   
   VALID 272044Z - 272145Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 194 CONTINUES.
   
   LARGE HAIL THREAT CONTINUES AND TORNADIC POTENTIAL SHOULD INCREASE
   /ESPECIALLY ALONG THE WARM FRONT NEAR THE I-70 CORRIDOR/...AS
   SUPERCELL COVERAGE LIKELY INCREASES HERE IN THE NEXT FEW HOURS.
   FARTHER S...SHOWERS HAVE STRUGGLED TO INTENSIFY ACROSS S-CNTRL KS
   AND UNCERTAINTIES EXIST OVER THE SUSTAINABILITY OF SEVERE TSTMS WITH
   SRN EXTENT.
   
   20Z SURFACE ANALYSIS PLACED A 995 MB CYCLONE AROUND 40 N RSL WITH AN
   ATTENDANT WARM FRONT EXTENDING SEWD TO NEAR EMP TO 20 E JLN...AND A
   SURGING DRYLINE EXTENDING SWD NEAR ICT TO PNC. MOST PERSISTENT
   CLUSTER OF TSTMS HAS PRODUCED SEVERE HAIL IN PORTIONS OF N-CNTRL
   KS...ALONG AND JUST N OF THE SURFACE FRONT. RELATIVELY GREATER HAIL
   AND TORNADO POTENTIAL WILL EXIST ALONG THE FRONT AS ADDITIONAL
   SURFACE-BASED CELLS LIKELY PROPAGATE WITHIN THIS ZONE...BEFORE
   BECOMING INCREASINGLY ELEVATED WITH NRN EXTENT.
   
   DISCRETE CELLS ALONG THE DRYLINE IN S-CNTRL KS HAVE STRUGGLED TO
   INTENSIFY AS FORCED ASCENT TIED TO THE COMPACT NWRN KS/SWRN NEB
   IMPULSE HAS REMAINED FARTHER N. MODIFIED 18Z LMN RAOB SUGGESTS THAT
   ALTHOUGH MLCIN IS MINIMAL...LOW RH AOA 3000 FT AGL IS LIKELY
   RESULTING IN SUBSTANTIAL ENTRAINMENT OF DRY AIR WITH MIXED-LAYER
   PARCELS. STILL...WITH STRONG LOW-LEVEL CONVERGENCE ALONG THE DRYLINE
   AND A COUPLE MORE HOURS OF BOUNDARY LAYER HEATING...ALONG WITH
   WEAKENING LARGE-SCALE DESCENT AS THE KS/NEB IMPULSE DAMPENS...A CELL
   OR TWO COULD BECOME SUSTAINED INTO SERN KS BY EARLY EVENING.
