...SLIGHT RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND TONIGHT...

FORECAST...SCATTERED SHOWERS AND THUNDERSTORMS ARE EXPECTED THROUGH
THIS EVENING ACROSS THE ENTIRE REGION WITH THE GREATEST CONCENTRATION
OF ACTIVITY ALONG THE IOWA BORDER. THUNDERSTORMS ARE EXPECTED TO BECOME
MORE WIDESPREAD ACROSS NORTHWEST SECTIONS TONIGHT...GENERALLY NORTHWEST
OF A ST JOSEPH TO BETHANY LINE. THE THUNDERSTORMS MAY BECOME SEVERE
WITH LARGE HAIL AND DAMAGING WINDS THE PRIMARY THREAT. THE GREATEST
THREAT OF SEVERE WEATHER WILL BE NORTH OF THE MISSOURI RIVER THIS
AFTERNOON AND EVENING. SPOTTER ACTIVATION IS POSSIBLE THIS AFTERNOON
AND TONIGHT.

DISCUSSION...A WARM FRONT HAS LIFTED NORTH INTO SOUTHEAST NEBRASKA AND
SOUTHERN IOWA WITH A WEAK COLD FRONT PUSHING SLOWLY SOUTHEAST INTO
CENTRAL NEBRASKA. THE AIR MASS TO THE SOUTH OF THESE FEATURES HAS
BECOME VERY UNSTABLE THIS AFTERNOON. ALTHOUGH NO SURFACE FRONTS ARE
EXPECTED TO INTERACT WITH THE UNSTABLE AIR MASS...A WEAK UPPER LEVEL
DISTURBANCE WILL LIKELY TRIGGER SCATTERED THUNDERSTORMS ACROSS THE
REGION THROUGH THIS EVENING.

IN ADDITION...THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG THE WEAK COLD
FRONT IN SOUTHERN NEBRASKA LATE THIS AFTERNOON AND MOVE INTO NORTHWEST
MISSOURI TONIGHT.

VE\RY WARM AND HUMID CONDITIONS ARE ALSO EXPECTED THIS AFTERNOON WITH
TEMPERATURES AROUND 90 DEGREES IN MOST LOCATIONS. THE HUMID CONDITIONS
WILL PUSH HEAT INDEX VALUES TO AROUND 100.
