SURFACE FRONT HAS REMAINED IN EXTREME SOUTHEAST CORNER OF CWA...LIKELY JUST CLIPPING IDA COUNTY...THROUGH MUCH OF THE AFTERNOON...WILL SLIP VERY SLOWLY SOUTHEAST THROUGH THE NIGHT. EVEN WITH THE EXITING SHOWERS...WILL HANG ONTO A CHANCE OF SHOWERS AND A FEW THUNDERSTORMS ACROSS THE SOUTHERN CWA INTO THE EVENING WITH LINGERING ELEVATED INSTABILITY...THEN CHANCES SLOWLY DECREASING FROM THE NORTH AS THE FRONT SHIFTS SOUTH OVERNIGHT. SHOULD BE A MORE COMFORTABLE NIGHT WITH REGARDS TO HUMIDITY LEVELS AND TEMPERATURES...WITH READINGS FALLING INTO THE LOWER TO MID 60S MOST AREAS. RELATIVELY QUIET WEATHER EXPECTED THROUGH THE WEEKEND...ALTHOUGH WITH LOW PRESSURE DEVELOPING IN THE WESTERN PLAINS...AND LINGERING FRONT EXTENDING SOUTHEAST TOWARD MISSOURI RIVER...FEEL A SLIGHT CHANCE OF LATE AFTERNOON AND EVENING THUNDERSTORMS STILL WARRANTED IN THE WESTERN AND SOUTHERN CWA ON SATURDAY.
