AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 915 PM CDT THU SEP 2 2004 .DISCUSSION...SCATTERED CONVECTION OCCURRING ACRS THE EXTREME SE THIS EVENING IN AREA OF DECENT LOW LVL MOISTURE CONVERGENCE AND WITH WEAK MID LVL SHORTWAVE ROTATING NWD ACRS THE OHIO VALLEY. FEATURE TO CONTIUNE DRIFTING NWD OVERNIGHT HELPING TO KEEP A LEAST LOW THREAT OF SHOWERS ACRS OUR EASTERN COUNTIES...MAINLY EAST OF I-57. CURRENT ZONE BREAKUP HAS A GOOD HANDLE ON CURRENT AND EXPECTED WEATHER OVRNGT SO OTHER THAN SOME MINOR TWEEKING OF THE WORDING IN THE FIRST PERIOD...FEW OTHER CHANGES NEEDED. && .DISCUSSION... SHORT TERM...TONIGHT THROUGH SATURDAY... OVERALL QUIET WEATHER EXPECTED THROUGH THE FIRST PART OF THE WEEKEND...BUT THERE ARE A COUPLE OF FEATURES TO KEEP AN EYE ON. WEAK SURFACE RIDGE CENTERED OVER ILLINOIS IS PROVIDING LIGHT WINDS AND SUBSIDENCE TO THE REGION. LIGHT EASTERLY LOW LEVEL FLOW IS ALLOWING DEWPOINTS TO SLOWLY RISE OVER THE SOUTHEASTERN COUNTIES...AS A SHORTWAVE OVER THE TENNESSEE VALLEY MOVES NORTHWARD. THIS FEATURE IS HANDLED DIFFERENTLY BY THE ETA AND GFS...WITH THE LATTER BEING FURTHER WEST WITH ITS QPF. CONSIDERING THE LAYOUT OF THE CONVECTION THIS AFTERNOON...AND THE SOUTHWESTERLY FLOW THE SHORTWAVE IS EMBEDDED IN...WILL SIDE WITH THE DRIER ETA FOR QPF ON FRIDAY. WILL CARRY CHANCE POPS FOR THE EASTERN COUNTIES...WITH LOWER POPS FURTHER WEST. AS THIS FEATURE SHIFTS NORTHEASTWARD AWAY FROM THE AREA...SUPPORT FOR PRECIPITATION WILL DIMINISH...BUT MOISTURE AND TEMPERATURE TRENDS WILL CONTINUE TO BE UPWARD WITH NO SUBSTANTIAL CHANGE IN AIRMASS. LONG TERM...SUNDAY THROUGH THURSDAY... STRONG NORTHERN STREAM UPPER TROUGH OVER THE NORTHWESTERN CONUS WILL SLOWLY EDGE ITS WAY INTO THE MISSISSIPPI VALLEY REGION THE LATTER PART OF THE WEEKEND. THERE HAS BEEN QUITE A FEW INCONSISTENCIES WITH THE VARIOUS MODELS ON HOW FAST THIS FEATURE WILL PROGRESS. AGREEMENT IS A LITTLE BETTER WITH THE 12Z MODEL SUITE...AND BELIEVE THAT SLOWER IS THE WAY TO GO. WILL GO AHEAD AND KEEP CHANCE POPS IN THE SOUTHEASTERN ZONES LATE SATURDAY NIGHT...BUT THE BETTER CHANCES WILL HOLD OFF UNTIL SUNDAY AND SUNDAY NIGHT. MOISTURE WILL CONTINUE ITS SLOW INCREASE...BUT THE DEEPER MOISTURE WILL BE RESTRICTED BY THE SURFACE RIDGE TO THE NORTHWEST OF HURRICANE FRANCES. AS THE FRONT APPROACHES MONDAY MORNING...ITS PROGRESS WILL LIKELY BE SLOWED UP BY FRANCES. WITH THE DISSIPATING SURFACE BOUNDARY IN THE AREA...WILL HAVE TO KEEP CHANCE POPS GOING AT LEAST IN THE CENTRAL AND SOUTH THROUGH TUESDAY. THE EXACT PATH OF FRANCES WILL BECOME AN ISSUE WITH PRECIPITATION CHANCES DURING MID WEEK. THE LATEST LONGER RANGE MODELS HAVE BEEN TRENDING FURTHER WEST WITH THE REMNANTS OF THE HURRICANE...AND THE LATEST NHC/HPC GUIDANCE BRINGS IT ACROSS TENNESSEE AND KENTUCKY IN THE WEDNESDAY TIMEFRAME. RAINFALL ON THE WESTERN PERIFERY OF THE REMANT LOW PRESSURE AREA MAY THREATEN THE SOUTHEASTERN ZONES...BUT THE EXACT TRACK IS STILL TO UNCERTAIN TO INTRODUCE MENTIONABLE POPS AT THIS TIME. WILL PUT IN 20 POPS OVER THE SOUTHEAST ON WEDNESDAY. THE GFS STARTS TO BRING RETURN FLOW INTO THE CENTRAL PLAINS ON THURSDAY AND BRINGS ITS QPF INTO THE WESTERN PORTIONS OF THE AREA. WILL HOLD OFF ON ANY POPS THIS FAR OUT TO SEE IF THE REMANTS OF THE HURRICANE SLOW THE PROGRESSION OF SYSTEMS UPSTREAM. && .ILX WATCHES/WARNINGS/ADVISORIES... .IL...NONE. && SMITH/04
