CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 072322Z - 080015Z

PROBABILITY OF WATCH ISSUANCE...40 PERCENT

SUMMARY...THUNDERSTORMS ARE EXPECTED TO GRADUALLY EXPAND IN AREAL
COVERAGE AND INTENSITY OVER THE NEXT FEW HOURS ACROSS PORTIONS OF
NERN KS INTO WCNTRL MO.  HAIL MAY ACCOMPANY THIS ACTIVITY.

DISCUSSION...LEADING EDGE OF MODIFIED GULF AIRMASS IS ADVANCING
STEADILY NWD WITH 50+F SFC DEW POINTS NOW ALONG/NORTH OF I-70
CORRIDOR ACROSS NERN KS INTO WCNTRL MO.  WITH LLJ EXPECTED TO FOCUS

SOME CONCERN THE STRONGEST STORMS MAY GENERATE HAIL IN EXCESS OF ONE
