By late tomorrow night, a quick moving shortwave will bring chances for scattered showers and thunderstorms. With CAPE values of 500-1000 J/kg in place, a few stronger storms are possible, but things should remain sub-severe. QPF amounts will be on the order of a few hundredths to a tenth of an inch.
