...SEVERE WEATHER EXPECTED ACROSS THE REGION THIS AFTERNOON AND
EVENING...

A MODERATE RISK FOR SEVERE WEATHER EXISTS ACROSS THE REGION GENERALLY
WEST OF A WEST PLAINS TO FORT LEONARD WOOD LINE FOR THIS AFTERNOON AND
EVENING. THIS INCLUDES BOTH THE JOPLIN AND SPRINGFIELD AREAS.

A WARM FRONT EXTENDED ACROSS THE CENTER OF THE STATE INTO A LOW
PRESSURE CENTER OVER SOUTHCENTRAL KANSAS LATE THIS MORNING.  SOUTH TO
SOUTHWEST WINDS IN THE LOWER LEVELS OF THE ATMOSPHERE WERE PUMPING WARM
MOIST AIR INTO THE AREA.  THE COMBINATION OF AFTERNOON HEATING...THE
APPROACHING FRONT...AND THE PASSAGE OF AN UPPER LEVEL SYSTEM WILL SET
OFF STRONG TO SEVERE THUNDERSTORMS ACROSS THE REGION THIS AFTERNOON.

SEVERE WEATHER HAS BEEN SCATTERED GENERALLY NORTHEAST OF A WARSAW TO
SALEM LINE DURING THE MORNING HOURS.  AS THESE STORMS MOVE
SOUTHWARD...SEVERE WEATHER IS LIKELY TO CONTINUE.  LATER THIS
AFTERNOON...THUNDERSTORMS WILL BEGIN TO FORM OVER EASTERN KANSAS AND
NORTHEASTERN OKLAHOMA AND WILL MOVE INTO WESTERN SECTIONS.  THE GREATEST
THREAT WITH THE SEVERE THUNDERSTORMS WILL BE DAMAGING WIND GUSTS...AND
HAIL UP TO THE SIZE OF GOLFBALLS.

SPOTTER ACTIVATION WI$LL LIKELY BE REQUIRED THROUGHOUT THE AFTERNOON AND
EVENING HOURS.  EMERGENCY MANAGERS AND SPOTTER GROUPS SHOULD CONTINUE
TO MONITOR THE WEATHER SITUATION FOR POSSIBLE ACTIVATION.
