...MODERATE RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHEAST MISSOURI
THIS AFTERNOON AND TONIGHT...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTHEAST MISSOURI...SOUTHERN
ILLINOIS...SOUTHWEST INDIANA AND WESTERN KENTUCKY.

.DAY ONE...TODAY AND TONIGHT

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
TONIGHT ACROSS SOUTHEAST MISSOURI.  A SLIGHT RISK HAS BEEN POSTED
FOR THE REMAINDER OF THE QUAD STATE.

SCATTERED THUNDERSTORMS WILL BE POSSIBLE ACROSS THE QUAD STATE
THROUGH THE DAY...AND A FEW OF THESE STORMS MAY BECOME SEVERE WITH
LARGE HAIL BEING THE PRIMARY THREAT.

THIS AFTERNOON...SEVERE THUNDERSTORMS ARE EXPECTED TO DEVELOP NEAR A
FRONTAL BOUNDARY ACROSS WESTERN PORTIONS OF MISSOURI AND ARKANSAS.
THESE STORMS WILL MOVE QUICKLY NORTHEAST AND MAY REACH SOUTHEAST
MISSOURI BY EARLY EVENING.  THESE STORMS ARE EXPECTED TO ORGANIZE
INTO ONE OR MORE LINES THIS EVENING AND SWEEP ACROSS THE REMAINDER
OF THE QUAD STATE OVERNIGHT.

SUPERCELL STORMS WITH LARGE HAIL...DAMAGING WINDS AND THE POTENTIAL
FOR TORNADOES WILL BE POSSIBLE ACROSS SOUTHEAST MISSOURI LATE THIS

BE EXPECTED LATER AS THE STORMS FORM A LINE.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE QUAD STATE
