.DISCUSSION...
ISSUED 1023 AM CDT MON JUN 6 2011
WARM FRONT IS IN THE PROCESS OF LIFTING NORTHEASTWARD THROUGH
CENTRAL ILLINOIS THIS MORNING...ALLOWING WARMER AND MORE HUMID AIR
TO SURGE INTO THE AREA. A LARGE CLUSTER OF THUNDERSTORMS IS CURRENTLY
ONGOING AHEAD OF THE FRONT ACROSS EASTERN WISCONSIN...WITH
HIGH/THIN CONVECTIVE DEBRIS FROM THIS COMPLEX SPILLING SOUTHWARD
INTO THE NORTHEAST KILX CWA AROUND CHAMPAIGN AND DANVILLE. STORM
COMPLEX IS EXPECTED TO STAY WELL TO THE NORTH TODAY AS IT TRACKS
E/SE INTO MICHIGAN. SKIES WILL REMAIN MOSTLY SUNNY ACROSS CENTRAL
ILLINOIS...WITH PERHAPS A FEW DIURNAL CU DEVELOPING THIS
AFTERNOON. THANKS TO SOUTHWESTERLY WINDS AND FULL SUNSHINE....HIGH
TEMPERATURES WILL REACH THE LOWER TO MIDDLE 90S. 15Z READINGS HAVE
ALREADY CLIMBED WELL INTO THE 80S...SO CURRENT FORECAST APPEARS TO
BE RIGHT ON TRACK.

ISSUED 615 AM CDT MON JUN 6 2011
OTHER THAN SOME PATCHY MVFR VSBYS IN FOG AND HAZE EARLY THIS
MORNING...WE EXPECT VFR CONDITIONS TO PREVAIL THIS FORECAST
PERIOD. WARM FRONT IS EXPECTED TO SHIFT NORTH OF THE AREA LATER
THIS MORNING WITH ANY THREAT OF CONVECTION REMAINING TO THE NORTH
OF OUR TAF SITES. SATELLITE DATA AND SURFACE OBS OVER EASTERN IL
INDICATE SOME SCT-BKN MID LEVEL CLOUDS AND A FEW SPRINKLES TRACKING

SOUNDINGS SUGGEST SOME SCATTERED CU FORMING BETWEEN 4000-5000FT...ESP
FROM BMI TO CMI...FORMING AFTR 15Z. SFC WINDS WILL BE OUT OF THE

.PREV DISCUSSION...
ISSUED 220 AM CDT MON JUN 6 2011
EARLY THIS MORNING...ILLINOIS WAS ON THE PERIPHERY OF A SURFACE
HIGH PRESSURE RIDGE JUST TO OUR EAST. THE STATIONARY FRONT THAT
HAS BEEN OVER THE AREA RECENTLY IS A BIT TRICKY TO PICK OUT AMONG
THE SURFACE OBSERVATIONS...BUT APPEARS TO BE JUST WEST OF THE
MISSISSIPPI RIVER. HAVE HAD A NARROW BAND OF MID LEVEL CLOUDS
STREAMING ACROSS THE CWA FROM THE NORTHWEST...THE REMNANTS OF SOME
SHOWER ACTIVITY IN EASTERN IOWA LATE SUNDAY EVENING...ALTHOUGH AN
MCS IS BEGINNING TO FORM FURTHER UPSTREAM ACROSS NORTHEAST IOWA
AND SOUTHEAST MINNESOTA.
HEAT AND HUMIDITY CONCERNS THROUGH WEDNESDAY ARE THE PRIMARY
FORECAST ISSUE...FOLLOWED BY CONVECTIVE POTENTIAL FOR THE SECOND
HALF OF THE WEEK.
SHORT TERM...TODAY THROUGH WEDNESDAY...
UPPER RIDGING OVER THE PLAINS PROGGED TO MOVE BACK EASTWARD...AND
SHOULD BE CENTERED ALONG THE EAST COAST BY LATE WEDNESDAY
AFTERNOON. TEMPERATURES IN THE LOWER 20S CELSIUS AT 850 MB WILL
SUPPORT HIGH TEMPERATURES INTO THE 90S...WITH TUESDAY AND
WEDNESDAY THE WARMEST WITH MID 90S OR SLIGHTLY HIGHER. MAY SEE A
COUPLE LOCATIONS FLIRTING WITH RECORD HIGHS...ALTHOUGH RECORDS IN
MOST LOCATIONS ARE AROUND 99 DEGREES ON TUESDAY...AND RANGE FROM
95-99 DEGREES ON WEDNESDAY. FORECAST SOUNDINGS INDICATING
AFTERNOON DEWPOINTS SHOULD BE IN THE MID TO UPPER 60S...ENOUGH TO
BRING THE HEAT INDEX UP TO AROUND 100 DEGREES EACH DAY THROUGH
WEDNESDAY. IF THE HEAT WAVE WERE TO LAST ANY LONGER...THAT WOULD
BE ENOUGH TO JUSTIFY A HEAT ADVISORY DESPITE NOT MEETING THE DAILY
CRITERIA OF 105. HOWEVER...NO ADVISORIES ARE PLANNED AT THIS TIME.
LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY...
CONVECTIVE CONCERNS ARE EXPECTED DURING THIS PERIOD. A CUTOFF LOW
JUST OFF THE CALIFORNIA COAST EARLY THIS MORNING WILL MOVE ONSHORE
AND SHEAR OUT THE NEXT COUPLE DAYS...WITH A REMNANT PIECE OF
ENERGY FORMING A SHORTWAVE ALONG THE U.S. AND CANADIAN BORDER BY
WEDNESDAY. ASSOCIATED SURFACE FRONT IS EXPECTED TO DROP INTO
NORTHERN ILLINOIS WEDNESDAY NIGHT...BUT ITS SOUTHWARD PROGRESSION
WILL BE SLOWED AS THE UPPER RIDGE FLATTENS AND BULGES WESTWARD
ALONG THE GULF COAST.
THE LONGER RANGE MODELS ARE HAVING SOME DISAGREEMENTS IN HOW FAST
TO BRING THE BOUNDARY THROUGH THE CWA...WITH THE GFS AND CANADIAN
MOST PROGRESSIVE...ALTHOUGH AFTER 12Z FRIDAY THE CANADIAN BEGINS
TRENDING MORE TOWARD THE ECMWF. WITH CONVECTIVE DEVELOPMENT
DEPENDENT ON MESOSCALE FACTORS...AM NOT PLANNING ON ANY MAJOR
CHANGES TO RAIN CHANCES. HOWEVER...HAVE TRENDED TEMPERATURES
DOWNWARD A BIT FOR THURSDAY AND FRIDAY...PRIMARILY ACROSS THE
NORTHERN CWA WHICH IS MOST LIKELY TO BE NORTH OF THE BOUNDARY.
