AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 155 PM CDT TUE SEP 14 2004 .DISCUSSION... SHORT TERM...TODAY THROUGH THURSDAY... BIGGEST CHALLENGE THIS AFTERNOON IS RELATED TO TIMING PRECIPITATION RELATED TO INCOMING FRONTAL SYSTEM WEDNESDAY INTO THURSDAY. 12Z GFS AND ETA SUGGEST ONGOING ACTIVITY IS EXPECTED TO DIMINISH LATER THIS AFTERNOON AS WAVE MOVES NORTHEAST OF FORECAST AREA. LATEST RUC KEEPS LIFT IN PLACE IN NORTH AND EAST THROUH 00Z BUT DECREASES BY 03Z. RUC HAS BEEN HANDLING PRECIP RELATIVELY WELL TODAY AND ANTICIPATE ADDING SLIGHT CHC POPS TO NORTH AND EAST FOR EARLY EVENING...BUT WILL MAKE FINAL DECISION JUST BEFORE PUBLISHING FINAL GRIDS. 12Z NCEP MODELS HAVE SLOWED FRONT APPROACHING ILLINOIS ON WEDNESDAY. THIS SHOULD ALLOW DECENT INSOLATION THROUGH MUCH OF THE DAY ENHANCING INSTABILITY. WHERE THIS INSTABILITY INTERACTS WITH THE BEST DYNAMICS ASSOCIATED WITH SIGNIFICANT SHORT WAVE MOVING ACROSS MISSISSIPPI RIVER THERE IS A CHANCE OF STRONG CONVECTION. BOTH ETA AND GFS SUGGESTS THIS THREAT AREA WILL BE PRIMARILY NORTH OF I-72 LATE WEDNESDAY AFTERNOON AND EVENING. GFS AND ETA BOTH HAVE SLOWED FRONTS EXIT FROM SOUTHEAST ILLINOIS COMPARED TO PREVIOUS RUNS AS RIDGE BUILDS AHEAD OF IVAN. WILL KEEP POPS GOING THROUGH THURSDAY OVER SOUTHEAST ILLINOIS WHERE POST FRONTAL PRECIP MAY BE ENHANCED BY POTENTIAL OVERRUNNING OF THE BOUNDARY BY TROPICAL MOISTURE ON FRINGE OF HURRICANE IVAN REMNANTS. LONG TERM...FRIDAY THROUGH TUESDAY... NEXT CHALLENGE WILL BE WHETHER SOUTHEAST ILLINOIS WILL BE ADDITIONALLY IMPACTED BY MOISTURE ASSOCIATED WITH THE REMNANTS IVAN. 12Z MODELS SUGGEST THAT PRECIP WILL REMAIN GENERALLY SOUTHEAST OF FORECAST AREA. HOWEVER...THERE IS VERY LIGHT STEERING FLOW PROGGED AND ANY DRIFT TO THE WEST OF FORECASTED POSITION MAY BRING SOME PRECIP INTO AREA SOUTHEAST OF I-70 FRIDAY AND FRIDAY NIGHT. FOR NOW WILL KEEP THIS AREA DRY...BUT WILL MONITOR CLOSELY FOR CHANGES IN THE TRACK OF IVAN. && .ILX WATCHES/WARNINGS/ADVISORIES... .IL...NONE. BARKER
