AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 135 PM CDT THU JUL 27 2006 .DISCUSSION... BIGGEST CHALLENGES THIS PACKAGE REVOLVE AROUND EVOLUTION OF PRECIPITATION IN THE SHORT-TERM...HEAT OVER THE WEEKEND...AND CHANCE OF PRECIP TOWARD WEDNESDAY AND THURSDAY. SHORT TERM...TONIGHT THROUGH FRIDAY NIGHT... COMPLICATED PATTERN EXPECTED OVER NEXT 36 HOURS OVER THE MIDWEST AS A TRAIN OF SHORT WAVES EVIDENT IN WATER VAPOR IMAGERY CROSS THE AREA. DEW POINTS IN THE 70S AND A PLETHORA OF BOUNDARIES LEFT OVER FROM LAST NIGHTS STORMS WILL ADD FUEL TO THE MIX. THEN THROW IN A WEAK SURFACE LOW OVER NORTH CENTRAL ILLINOIS COMBINED WITH A CONVERGENCE BOUNDARY EXTENDING SOUTHWEST FROM THE LOW INTO UIN AREA AND IT APPEARS CHANCES ARE GOOD FOR CONVECTION OVERNIGHT INTO FRIDAY. 18Z SOUNDING SHOWING MIXING HEIGHT NEAR 16.6 KFT SO HAIL THREAT IS EXTREMELY LIMITED BUT LOW LCL AND BOUNDARIES SUPPORT THE POSSIBILITY OF A REPEAT OF YESTERDAYS TORNADO EVENT. BEST THREAT MAY BE HEAVY RAINFALL ONCE AGAIN. WITH OVER SIX INCHES IN PARTS OF THE REGION LAST NIGHT...WE WILL BE ISSUING A FLOOD WATCH FROM SCHUYLER COUNTY EAST TO CHAMPAIGN COUNTY. CONVECTION SHOULD PUSH REMNANTS OF THE BOUNDARY INTO SOUTHERN ILLINOIS...BUT WITH BUILDING HEIGHTS BY LATE FRIDAY BOUNDARY WILL LIKELY WASH OUT BY FRIDAY NIGHT. TEMPS SHOULD CONTINUE TO BE ABOVE NORMAL GIVEN 850 TEMPS EXPECTED OVER 18C AND A RETURN OF SUN THROUGH MUCH OF CWA FRIDAY. LONG TERM...SATURDAY THROUGH THURSDAY... MODELS CONSISTENT IN MID-LEVEL RIDGE BUILDING IN OVER THE WEEKEND. HOWEVER THEY DO DIFFER WITH STRENGTH WITH GFS KEEPING GENERALLY LOWER HEIGHTS. ECMWF HAS BEEN MORE CONSISTENT WITH ITSELF AND UKMET AND CANADIAN AND IS PREFERRED KEEPING HEIGHTS ABOUT 30 METERS HIGHER THAN GFS. THIS SHOULD LEAD TO STRONGER CAP AND HIGHER TEMPS THAN MEX GUIDANCE SUGGESTS. WILL KEEP GOING FORECAST WHICH IS ABOUT ONE CATEGORY HIGHER. THE DIFFERENCE IN THE STRENGTH OF THIS RIDGE ALSO HAS A BEARING ON WHEN CHANCES OF PRECIP WILL RETURN TO REGION. 12Z GFS MOVES A SIGNIFICANT WAVE INTO THE RIDGE BREAKING IT DOWN ON WEDNESDAY AND THEN PUSHING A COLD FRONT THROUGH WEDNESDAY NIGHT. GIVEN THE STRENGTH OF THE RIDGE AGAIN FAVOR ECMWF SLOWER EVOLUTION AND QUESTION HOW FAR AND FAST THIS FRONT WILL MOVE INTO THE MIDWEST. WILL GO AHEAD AND INTRODUCE POPS WEDNESDAY THROUGH THURSDAY BUT WILL GO LOW WITH UNCERTAINTY HIGH. HEAT INDEX SHOULD BE OCCASIONALLY IN THE 100 TO 105 RANGE WITH HIGHS IN THE 90S AND DEW POINTS IN THE 70S. VALUES ARE NOT QUITE TO HEAT ADVISORY CRITERIA...BUT LATER SHIFTS WILL NEED TO MONITOR THE SITUATION FOR SUNDAY THROUGH TUESDAY CLOSELY. && .ILX WATCHES/WARNINGS/ADVISORIES...
