IN ADDITION... A LINE OF STORMS IS EXPECTED TO DEVELOP LATE TONIGHT TO THE WEST AND MOVE INTO OSAGE AND PAWNEE COUNTIES BY MORNING.

IT IS EXPECTED THAT THE STORMS WILL MOVE QUICKLY ENOUGH TO KEEP RAIN TOTALS IN THE 1 TO 2 INCH RANGE AT MOST. HOWEVER EVEN THIS MIGHT BE ENOUGH FOR FLOODING PROBLEMS IN SOME AREAS.
