ADVSRYS ATTM.  RIVERS ARE ONLY SHOWING MINOR RESPONSES AS OF YET.
COLD FRONT SHOWS UP WELL ON RADAR IMAGERY.  FRONT APPEARS TO BE
SURGING EWD ACROSS WRN IL AT ABOUT 40 MPH.  THIS WOULD BRING THE
FRONT THROUGH RFD AND CHI AROUND 1800 AND THROUGH ERN PORTION OF FA
LATER THIS EVE.  FRONT HAS BEEN A GOOD DELINEATOR FOR THE BACK EDGE
OF HEAVIER RAIN.  THIS BOUNDARY MAY SLOW UP AS IT HEADS INTO IN THIS
