FOR A FEW SHOWERS AND THUNDERSTORMS TO THE AREA LATE TONIGHT AND
INTO MONDAY.  RELIEF FROM THE HEAT WILL BEGIN TO ARRIVE TUESDAY AS A
COLD FRONT PASSES THROUGH THE REGION. WHILE SOME HEAT INDICES WILL
STILL RISE TO AROUND 100 DEGREES WITH WARM AIR ADVECTION AHEAD OF
THE FRONT IN SOUTHWEST IOWA AND EXTREME SOUTHEAST NEBRASKA...HIGH
TEMPS IN NORTHEAST NEBRASKA WILL ONLY BE IN THE MID TO UPPER 80S.
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO BE POSSIBLE ALONG THE
FRONTAL BOUNDARY MONDAY EVENING THROUGH TUESDAY NIGHT. WITH PLENTY
OF INSTABILITY AND DECENT SHEAR IN THE REGION...A FEW OF THESE
STORMS COULD BECOME STRONG TO SEVERE MONDAY NIGHT.

COOLER TEMPERATURES WILL CONTINUE INTO THE EXTENDED PERIOD AS A RIDGE
OF HIGH PRESSURE BUILDS OVER THE WESTERN HALF OF THE

TEMPERATURES WILL REMAIN IN THE 80S THROUGH THE WEEKEND...SLIGHTLY
BELOW CLIMO NORMS.  A FEW PERIODS OF SHOWERS AND THUNDERSTORMS WILL
