TSTMS WHICH HAVE PERSISTED OVER NERN KS THIS EVENING WITH CONVECTIVE
SYSTEM EXPECTED TO BECOME MORE PROGRESSIVE OVER THE NEXT 1-2 HOURS.
AMBIENT INFLOW AIR MASS REMAINS QUITE MOIST AND RELATIVELY WARM THIS
EVENING...HOWEVER MODIFICATION OF 00Z TOP SOUNDING FOR CURRENT
SURFACE CONDITIONS SUGGEST THAT CAP IS GRADUALLY INCREASING.
