AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 323 PM CDT THU AUG 11 2005 .DISCUSSION... MAIN CONCERNS ARE TRYING TO PINPOINT PRECIP CHANCES AND TEMPS WHILE THE STATIONARY FRONT MEANDERS ACROSS C IL. THE MODELS ARE HAVING A HARD TIME AGREEING ON SUBTLE SURFACE FEATURES ALONG THE BOUNDARY, POSSIBLY EVEN CYCLOGENESIS. THEY ALL EVENTUALLY LIFT A TROUGH THROUGH THE AREA OVER THE NEXT 24 TO 36 HOURS. THE NAM IS DEEPER AND FASTER WITH THE SYSTEM THAN THE GFS/CANADIAN, AND ENSEMBLE MEAN. GFS HAS ITS OWN ISSUES WITH CONVECTIVE FEEDBACK ALONG WITH THE NAM. WILL TRY TO GO WITH A BLEND FOR THIS RUN, ALTHOUGH CONFIDENCE IS NOT HIGH IN ANY SOLUTION AT THIS POINT. THEREFORE, NO MAJOR CHANGES EXPECTED WITH THIS UPDATE. SHORT TERM...TONIGHT THROUGH SATURDAY... THE LATEST SURFACE ANALYSIS INDICATES A STATIONARY BOUNDARY STILL PERSISTING FROM WEST TO EAST ACROSS THE CENTER OF OUR CWA. IT WILL BE OUR BEST CHANCE AT A FOCUS FOR CONVECTION TONIGHT. CURRENTLY, MOST OF THE CONVECTION HAS BEEN CONFINED TO AREAS NORTH OF THE BOUNDARY. WE HAD AN OUTFLOW BOUNDARY BLAST SOUTH ALL THE WAY THROUGH OUR CWA FROM THE CONVECTION EARLY THIS MORNING. THAT WILL MOST LIKELY NOT PLAY A FACTOR TONIGHT. I WILL GENERALLY KEEP THE HIGHER POPS IN THE NORTH AND LOWER POPS ALONG THE SOUTHERN TIER, AS PREV FORECAST. THIS SEEMS THE BEST SCENARIO GIVEN THE CONVECTIVE TRENDS OF LATE. THE WATER VAPOR LOOP IS NOT INDICATING MUCH IN THE WAY OF A SHORTWAVE IN OUR NEAR FUTURE. THE NONDESCRIPT PRESSURE PATTERN IS TOUGH TO LOCALIZE ANY CONVECTIVE INITIATION. HEAT OF THE DAY AND CONVECTIVE TEMP SEEMS AS GOOD AS ANY TRIGGER AT THIS POINT. THEREFORE, 30 AND 40 POPS SEEM THE BEST WAY TO DESCRIBE PERCENT OF COVERAGE. THE BASIC TREND OF THE FRONT APPEARS TO BE, REMAINING IN OUR NW ZONES TONIGHT...DROPPING A LITTLE FARTHER SOUTH INTO OUR CWA ON FRIDAY, AS A PRESSURE CENTER LIFTS TO THE NE OF ILLINOIS...THEN REMAINING STATIONARY FROM SW TO NE ACROSS OUR CWA AS THE NEXT SHORTWAVE LIFTS NE ALONG THE BOUNDARY ON SATURDAY AFTERNOON AND SUNDAY. WITHOUT A MAJOR CHANGE IN THE AIRMASS THROUGH ALL OF THIS, CONVECTIVE CHANCES WILL BE SCATTERED IN THE UNSTABLE AND MOIST CONDITIONS. THERE LOOKS TO BE VERY LITTLE CAP THROUGH THE SHORT TERM, BUT THE TRIGGERS ARE NOT STRONG. .LONG TERM...SATURDAY NIGHT THOUGH THURSDAY. THE NEXT WAVE IS EXPECTED TO LIFT NORTH ON SATURDAY NIGHT AND SUNDAY. THIS WILL DRAW ADDITIONAL MOISTURE AND BE A FOCUS FOR LIFT. HOWEVER, THE BEST CHANCE FOR PRECIP MAY BE ON MONDAY AFTERNOON, WHEN THE BOUNDARY WILL LIFT NORTH THOUGH OUR CWA AS A WARM FRONT. LOW LEVEL CONVERGENCE AND A PUSH OF MOISTURE FROM THE GULF, APPEAR TO AID IN PRECIP CHANCES MONDAY AFTERNOON. IT HARD TO ARGUE AGAINST SMALL PRECIP CHANCES INTO WEDNESDAY, AS A MID LEVEL SHORTWAVE LIFTS NE ALONG THE BOUNDARY THEN. I KEPT WED NIGHT AND THURSDAY DRY FOR THE TIME BEING. TEMPS WILL BE HOT AND HUMID AGAIN FRIDAY, BUT THEN THE BOUNDARY DROPS INTO THE SOUTHERN PART OF THE CWA FOR MUCH OF THE REST OF THE FORECAST. TEMPS SHOULD RESPOND TO THE DIP IN THE H85 TEMPS. STILL MID 80S LIKELY IN MUCH OF THE AREA, AND HUMIDITY LEVELS WILL REMAIN UNCOMFORTABLE. && .ILX WATCHES/WARNINGS/ADVISORIES... IL...NONE. SHIMON
