KLUK AND KCVG WILL BE ON THE WESTERN FRINGE OF THE PCPN SHIELD THROUGH THE MORNING INTO THE EARLY AFTERNOON...WITH KCMH AND KILN PREVAILING A BIT LONGER. MVFR WITH A FEW IFR CIGS ARE EXPECTED. FURTHER WEST...KDAY APPEARS LIKELY TO DODGE THE BULK OF THE STEADIEST PCPN. AS THE REMAINS OF IVAN PUSH INTO VA TODAY...THE PCPN WILL END NW TO SE LATE MORNING INTO MID AFTERNOON. IN CORRELATION...BY MID TO LATE AFTERNOON...CIGS SHOULD BECOME VFR AT THE TAF SITES...BEFORE BECOMING SCT LATE AFTERNOON INTO THE EVENING. && .PREVIOUS DISCUSSION... THE FOLLOWING WAS ORIGINALLY ISSUED AT 425 AM EDT FRI SEP 17 2004 SHORT TERM (TODAY THROUGH SUNDAY NIGHT)... MAIN CONCERN IS OBVIOUSLY THE EFFECTS OF THE REMNANTS OF IVAN. THE RAIN HAS BEEN A LITTLE SLOW TO SPREAD NORTH BUT IT IS MAKING PROGRESS WITH THE HEAVIEST RAIN STILL REMAINING SOUTH OF THE FORECAST AREA SO FAR. ALSO CONTINUE TO SEE SOME SHOWERS ALONG STALLED FRONTAL BOUNDARY STRETCHING ACROSS THE NORTHERN ZONES. MODELS ARE IN RATHER GOOD AGREEMENT WITH THE SYSTEM TAKING IT INTO EASTERN TENNESSEE AND THEN OFF INTO CENTRAL NORTH CAROLINA. THUS IT NOW APPEARS THAT THE EFFECTS OF IVAN WILL BE RELATIVELY SHORT LIVED FOR THE FORECAST AREA. MOST OF THE RAINFALL WILL OCCUR THROUGH 18Z AFTER WHICH TIME THE RAIN WILL TAPER OFF FROM WEST TO EAST. SOME RAIN MAY LINGER INTO THE EVENING IN EASTERN ZONES ALTHOUGH ANYTHING REMAINING AT THAT POINT WILL MOST LIKELY BE LIGHT. HEAVY RAINFALL CONTINUES TO BE A THREAT AND HAVE CONTINUED WITH THE FLOOD WATCH IN THE SOUTHEAST. HOWEVER HAVE SHORTENED THE LENGTH OF THE WATCH SO THAT IT ENDS DURING THE EVENING. THERE WILL CONTINUE TO BE A SHARP CUT OFF TO THE PRECIPITATION ON THE NORTHWEST EDGE OF THE SYSTEM. BUT UNCERTAINTY OF HOW FAR IT PROGRESSES ALONG WITH SOME RAIN CONTINUING ALONG THE REMNANTS OF THE FRONT RESULTS IN CHANCE POPS FOR THE NORTHWEST ZONES. HIGH PRESSURE WILL BUILD IN BEHIND THE TROPICAL SYSTEM. MODELS SUGGEST THAT THE COOLER DRIER AIRMASS WILL BE A LITTLE MORE PRONOUNCED THAN SHOWN PREVIOUSLY. SO HAVE LOWER TEMPERATURES... ESPECIALLY LOWS...AND ALSO DEW POINTS FROM SATURDAY THROUGH SUNDAY NIGHT. THERE SHOULD BE LITTLE CLOUD COVER ONCE TODAYS SYSTEM MOVES OUT. THE FOLLOWING WAS ORIGINALLY ISSUED AT 339 PM EDT THU SEP 16 2004 LONG TERM (SUNDAY THROUGH THURSDAY)...
