...POTENTIAL FOR FLOOD PRODUCING RAINS SOMEWHAT DIMINISHED...
...POTENTIAL FOR SEVERE THUNDERSTORMS THIS EVENING AND OVERNIGHT
STILL POSSIBLE...

COOL NORTHEAST WIND HELPED REINFORCE A STATIONARY BOUNDARY ALONG THE
IOWA MISSOURI BORDER...EXTENDING INTO CENTRAL ILLINOIS.  ALL HEAVY
AMOUNTS OF RAINFALL HAVE BEEN LIMITED TO AREAS SOUTH OF THIS FRONT...
MAINLY IN CENTRAL MISSOURI AND SOUTHERN ILLINOIS.  A LOW PRESSURE
SYSTEM...NOW LOCATED OVER CENTRAL KANSAS...WILL MOVE NORTHEAST
TODAY...FORCING WARM AIR TO MOVE BACK NORTH INTO PARTS OF SOUTHEAST
IOWA AND WEST CENTRAL ILLINOIS.  IF TEMPERATURES REACH INTO THE UPPER
70S AND LOWER 80S...THUNDERSTORMS WILL LIKELY DEVELOP...AND SOME

BE AFTER 5 PM...AND AREAS SOUTH OF INTERSTATE 80 AND WEST OF THE

FRONT...AND EVOLVE INTO A SQUALL LINE.  INDICATIONS ARE THAT THE
SQUALL LINE WOULD CROSS THE MISSISSIPPI RIVER INTO ILLINOIS AROUND
MIDNIGHT.  IF A LATE NIGHT SQUALL LINE DOES DEVELOP...THE PRIMARY
THREAT WILL BE DAMAGING STRAIGHT LINE WINDS OF 60 TO 80 MPH.
SUFFICIENT WIND SHEAR WILL EXIST THAT A POSSIBLE TORNADO CANNOT BE
RULED OUT.  DUE TO THE LATE NIGHT TIMING OF THIS POSSIBLE EVENT...ALL
