...THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND
EARLY TONIGHT...

CLEARING SKIES AND A STRONG RETURN OF TROPICAL MOISTURE WILL WORK TO
DESTABILIZE THE AIRMASS OVER EASTERN KANSAS AND WESTERN MISSOURI. A LOW
PRESSURE SYSTEM WITH A DRYLINE EXTENDING THROUGH CENTRAL KANSAS WILL
MOVE TO THE NORTHEAST THIS AFTERNOON. THUNDERSTORMS ARE EXPECTED TO
DEVELOP ALONG THE DRYLINE THIS AFTERNOON AND SPREAD INTO WESTERN
MISSOURI LATE THIS AFTERNOON AND EVENING.  THE MAIN THREAT OF SEVERE
WEATHER AT THIS TIME APPEARS TO BE FROM LARGE HAIL AND DAMAGING WINDS.
ISOLATED TORNADOES MAY ALSO BE POSSIBLE OVER NORTHERN SECTIONS OF THE
REGION WHERE STRONGER WIND SHEAR WILL FAVOR ROTATING THUNDERSTORMS.

THERE IS ALSO AN ADDITIONAL THREAT OF CONTINUED FLOODING AND FLASH
FLOODING FROM THESE THUNDERSTORMS THIS AFTERNOON AND EARLY
TONIGHT.

SPOTTER ACTIVATION MAY BE REQUIRED THIS AFTERNOON AND EARLY TONIGHT.
