AN AREA OF INSTABILITY UNDER A DEPARTING UPPER-LEVEL WAVE. THE
WAVE...AND REMAINING CHANCES FOR RAIN TONIGHT...WILL DEPART TO

AGAIN ON WEDNESDAY AFTERNOON. THE SETUP LOOKS FAVORABLE FOR
STRONG STORMS IN WESTERN OKLAHOMA.

THE MIDWEEK STORM SYSTEM WILL LEAVE A SURFACE FRONT OVER OKLAHOMA

THIS WILL RESULT IN CONTINUING CHANCE FOR RAIN AND THUNDERSTORMS.
