AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LINCOLN IL 1130 AM CDT THU JUL 22 2004 .DISCUSSION... UPDATED THE FORECAST LATE THIS MORNING TO LOWER CHANCES OF RAIN SE IL AND ELEVATE HIGHS TO LOWER 90S THIS AFTERNOON WHERE MORE SUNSHINE EXPECTED AND HIGHER HEAT INDICES FROM 100 TO 105. MAY NEED TO UPDATE AGAIN TO INCREASE CHANCE OF RAIN FROM THE IL RIVER VALLEY NW WHERE MCS IMPACTING SE IOWA AND NW IL AND DRIFTING ENE. 16Z SURFACE ANALYIS SHOWS A COLD FRONT NEAR THE WI/IL BORDER INTO SE IOWA AND CENTRAL KANSAS. THIS FRONT TO EASE SE TOWARD NORTHERN COUNTIES AROUND 00Z AND COLLDING WITH VERY UNSTABLE TROPICAL AIR MASS OVER CENTRAL IL WHERE LIFTED INDICES AROUND MINUS 10C AGAIN TODAY. WEAKER CAP THAN YESTERDAY PLUS BOUNDARY MOVING IN WILL PRODUCE GOOD CHANCE OF CONVECTION THIS AFTERNOON. SPC CONTINUES SLIGHT RISK OF SEVERE WX THIS AFTERNOON AND EVENING NW OF I-70. PRECIPITABLE WATER VALUES FROM 1.75 TO 2 INCHES TO ENHANCE CHANCES OF HEAVY RAIN THIS AFTERNOON NORTH OF I-70. TEMPS HAD WARMED INTO THE 80S FROM THE IL RIVER EAST AND DEWPOINTS IN THE 70S GIVING HEAT INDICES IN THE 90S AT 11 AM. EXPECT HIGHS TO RANGE FROM THE MID 80S NW BY GALESBURG TO LOWER 90S SE BY LAWRENCEVILLE WITH HEAT INDICES PEAKING NEAR 95 FROM PEORIA NW TO 100 TO 105 OVER SE IL. && .PREV DISCUSSION...MAIN FORECAST PROBLEM IN THE SHORT TERM CONTINUES TO BE THE FRONTAL BOUNDARY...WHEN IT WILL RAIN AND HOW MUCH RAIN WILL FALL. SHORT TERM...TODAY THROUGH FRIDAY NIGHT... 00Z ETA AND GFS CONTINUE TO BE VERY SIMILAR IN HOW THEY HANDLE THE FRONTAL BOUNDARY. HOWEVER GFS HAS FEEDBACK ISSUES AND WILL GO CLOSER TO ETA/S QPF NUMBERS IN THE SHORT TERM. FOR TODAY...SOME LINGERING SHOWERS AND THUNDERSTORMS EARLY THIS MORNING DUE TO OLD OUTFLOWS FROM MCS THAT MOVED SOUTHEAST ACROSS THE EASTERN HALF OF ILLINOIS LAST NIGHT. SO WILL KEEP HIGHER POPS IN THE SOUTHERN SECTIONS OF THE CWA DURING THE MORNING HOURS. IN THE MEANTIME...FRONT TO SLOWLY SINK TO THE SOUTH OVER THE CWA AND WILL BE ALONG THE I-72 COORIDOR BY 00Z. THIS WILL BE THE MAIN FOCUSING MECHANISM FOR ACTIVITY FOR THE NEXT 36 HOURS...WITH MID 70S DEWPTS POOLING ALONG THE BOUNDARY AND PWS IN EXCESS OF TWO INCHES. ETA AND GFS CONTINUE TO FORECAST LI/S APPROACHING MINUS 6 AND ILLINOIS REMAINS IN THE RIGHT ENTRANCE REGION OF THE UPPER LEVEL JET MAX THROUGH FRIDAY MORNING. HOWEVER...SURFACE BASED CAPES HAVE FALLEN FROM PREVIOUS MODEL RUNS AND ARE ONLY BETWEEN 1500 AND 2000 J/KG TODAY. BUT WITH SO MUCH WARMING ALOFT AND HIGHER DEWPTS ADVECTING IN...MUCAPES WILL BE BETWEEN 2000 AND 3000 J/KG...WITH A MAX NEAR 4500 J/KG OVER NORTHERN PORTIONS OF THE CWA THIS AFTERNOON. SPC/S NEW DAY ONE OUTLOOK HAS MOST OF CWA IN A SLIGHT RISK FOR THIS AFTERNOON AND TONIGHT...MAINLY ALONG AND NORTH OF I-70. WILL GO WITH HIGHER POPS ALL LOCATIONS FOR THIS AFTERNOON AND TONIGHT AND WILL ADD MENTION OF HEAVY RAINFALL POSSIBLE. AS FOR HIGH TEMPS TODAY...WITH ALL OF THE DEBRIS CLOUDS AND ONGOING CONVECTION STILL FEEL THAT UPPER 80S THE BEST BET...JUST A COUPLE OF DEGREES COOLER THAN THE MAV NUMBERS. SHOWERS AND THUNDERSTORMS WILL BE ONGOING FOR TONIGHT WITH SEVERAL ROUNDS OF PRECIPITATION. FRONT WILL CONTINUE TO SINK TO THE SOUTH AND WILL BE SOUTH OF THE OHIO RIVER BY 12Z. FOR FRIDAY...EVEN THOUGH FRONT WILL BE TO THE SOUTH OF CWA...SOME OVERRUNNING PCPN NOT OUT OF THE QUESTION AS ADDITIONAL SHORTWAVES MOVE EAST ALONG THE BOUNDARY. BY EARLY FRIDAY EVENING...PRECIPITATION WILL COME TO AN END WITH COOLER AND DRIER CONDITIONS RETURNING TO THE REGION. LONG TERM...SATURDAY THROUGH WEDNESDAY... NO MAJOR CHANGES MADE TO THE EXTENDED FORECAST AS EXTENDED GFS AND ENSEMBLES CONTINUE TO KEEP CWA RAINFREE THROUGH THE PERIOD WITH COOL AND DRY WEATHER. && .ILX WATCHES/WARNINGS/ADVISORIES...
