.DISCUSSION...
ISSUED 1040 AM CDT SUN JUN 13 2010

UPDATED THE FORECAST TO INCREASE CHANCES OF SHOWERS AND
THUNDERSTORMS ACROSS THE IL RIVER VALLEY WEST OF I-55 TO LIKELY
CHANCES TODAY. REST OF FORECAST APPEARS ON TRACK WITH ANOTHER
VERY WARM AND HUMID DAY WITH SCATTERED SHOWERS AND THUNDERSTORMS
DEVELOPING IN THE TROPICAL AIR MASS ESPECIALLY OVER THE IL RIVER
VALLYE. HIGHS IN THE UPPER 80S TO NEAR 90F WITH SE IL IN THE LOWER
90S WHERE AFTERNOON HEAT INDICES PEAK FROM 96 TO 101. THIS IS
BELOW THE HEAT ADVISORY CRITERIA AROUND 100F BUT WILL ISSUE A
SPECIAL WEATHER STATEMENT FOR SE IL TO ADDRESS THIS HIGH HEAT
AND HUMIDITY THIS AFTERNOON.

LOOP OF RADAR MOSAIC SHOWS LINE OF CONVECTION AS FAR EAST AS
EASTERN IA INTO WEST CENTRAL IL MOVING NE TOWARD SCHULER AND SCOTT
COUNTIES. WIDESPREAD CONVECTION OVER IA FROM MCS WITH ANOTHER LINE
OF CONVECTION EXTENDING ACROSS NW MO. WARM FRONT OF MCS TO LIFT NE
ACROSS CENTRAL IL THIS AFTERNOON AND BRING A MORE UNSTABLE AIRMASS
BACK INTO THE AREA WITH MLCAPES ELEVATING BETWEEN 2000-3000 J/KG
AND LIFTED INDICES OF MINUS 6-8C. THIS TO DEVELOP SCATTERED
SHOWERS AND THUNDERSTORMS AGAIN THIS AFTERNOON WITH BEST CHANCES
OVER THE IL RIVER VALLEY AND LESS COVERAGE IN SE IL WHERE MORE
SUNSHINE AND HOTTER. SPC HAS CENTRAL AND SOUTHERN IL FROM I-80 SOUTH
IN A SLIGHT RISK THIS AFTERNOON INTO MID EVENING WITH DAMAGING
WIND GUSTS THE MAIN SEVERE WX THREAT. WET MICROBURTS WILL ALSO
HAVE VERY HEAVY RAINS UP TO 1 INCH IN LESS THAN A HALF HOUR AND
FREQUENT CLOUD TO GROUND LIGHTNING. PRECIPITABLE WATER VALUES
AROUND 1.75 INCHES TO RISE BACK UP TO 2 INCH OR MORE LATER TODAY
SUPPORTING VERY HEAVY RAINS.

AREAS OF FOG AND LOCALLY DENSE HAS LIFTED BY LATE MORNING OVER NE
AREAS AND TEMPS HELD BACK IN THE MID 70S WHILE 80 TO 85F IN SW AREAS.
SO WARMEST AREAS IN SW TO REACH THE LOWER 90S AND WITH DEWPOINTS
70 TO 75F TO GIVE AFTERNOON HEAT INDEX READINGS OF 96 TO 101F AND
HOTTEST ALONG THE WABASH RIVER AGAIN NEAR LAWRENCEVILLE AND ROBINSON.

.AVIATION...
ISSUED 1255 PM CDT SUN JUN 13 2010

IVFR TO MVFR VISIBLITIES AND CEILINGS POSSIBLE WITH SHOWERS AND
THUNDERSTORMS THIS AFTERNOON AND EARLY EVENING OVER CENTRAL IL AND
AGAIN LATER TONIGHT AND MONDAY MORNING. HAVE WSW WIND GUSTS OF 35
TO 40 KTS AT PIA NEXT HOUR AND POTENTIALLY STRONGER WINDS AND THEN
INTO BMI IN ANOTHER HOUR OR TWO. THIS LINE OF CONVECTION WITH
GUSTY WINDS AND VERY HEAVY RAINS AND FREQUENT LIGHTNING COULD
DEVELOP SOUTHWARD TOWARD I-72 FROM SPI EAST TO CMI. ALSO SCATTERED
THUNDERSTORMS TO DEVELOP IN INCREASINGLY UNSTABLE AIR MASS OVER
CENTRAL IL DURING THIS AFTERNOON. MCS DEVELOPING OVER THE CENTRAL
PLAINS TONIGHT WILL MOVE INTO CENTRAL IL MON MORNING AS A FRONTAL
BOUNDARY IN NORTHERN IL SAGES SLOWLY SOUTHWARD INTO CENTRAL IL.
THIS WILL BRING ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS LATER
TONIGHT INTO MON WITH IFR TO MVFR CEILINGS AND VISIBILITIES AGAIN.
SW WINDS GENERALLY LESS THAN 10 KTS EXPECT GUSTY NEAR
THUNDERSTORMS.

.PREV DISCUSSION...
ISSUED 244 AM CDT SUN JUN 13 2010

MAIN FORECAST CONCERN CONTINUES TO BE HEAVY RAIN THREAT OVER THE
NEXT COUPLE OF DAYS...AS FRONTAL BOUNDARY REMAINS IN THE VICINITY.

07Z SURFACE ANALYSIS SHOWS STATIONARY FRONT EXTENDING FROM NORTHERN
ILLINOIS/INDIANA SOUTHWESTWARD INTO THE CENTRAL PLAINS. CONVECTION
HAS ONCE AGAIN DEVELOPED ON THE NOSE OF THE LOW-LEVEL JET ALONG THE
BOUNDARY ACROSS KANSAS AND THE TEXAS/OKLAHOMA PANHANDLES. ALOFT...
HIGH PRESSURE DOMINATES THE GULF COAST...WHILE DEEP LOW SPINS OVER
THE GREAT BASIN.

SHORT TERM...TODAY THROUGH TUESDAY
FIRST QUESTION OF THE DAY IS HOW THE ONGOING MCS ACROSS KANSAS WILL
EVOLVE LATER THIS MORNING. MODELS HAVE BEEN HANDLING CONVECTION
QUITE POORLY OVER THE PAST COUPLE OF DAYS...SO MUST LOOK AT CURRENT
RUN WITH A GOOD DEGREE OF SKEPTICISM. GFS DID NOT VERIFY WELL AT
06Z...AS IT PUSHED QPF BULLS-EYE TOO FAR NORTH TO THE
KANSAS/NEBRASKA BORDER...THEN FURTHER NORTHEAST INTO WESTERN IOWA BY
12Z. NAM-WRF/4KM WRF-NMM/LOCAL WRF ALL ARE IN VERY GOOD AGREEMENT
INITIALLY AND CORRECTLY PLACED THE 06Z QPF MAX OVER SOUTHERN KANSAS
AND THE OKLAHOMA PANHANDLE. WILL THEREFORE REJECT THE GFS AND FOLLOW
THE WRF CONSENSUS IN THE SHORT-TERM. LOW-LEVEL JET IS PROGGED TO
REMAIN IN A N/S ORIENTATION ACROSS THE SOUTHERN PLAINS THROUGH THE
MORNING...SO THE MCS WILL LIKELY TEND TO BACKBUILD AND REMAIN
VIRTUALLY STATIONARY ACROSS KANSAS INSTEAD OF SURGING E/SE AS THE
ONE YESTERDAY MORNING DID.

THE MAIN FOCUS FOR CONVECTION ACROSS CENTRAL ILLINOIS TODAY APPEARS
TO BE THE OLD OUTFLOW BOUNDARY LEFT BEHIND BY STORMS THAT ROLLED
THROUGH YESTERDAY. NAM-WRF PICKS UP ON THIS QUITE WELL...WITH
SCATTERED STORMS DEVELOPING ALONG THE BOUNDARY AS IT LIFTS
NORTHEASTWARD INTO WEST-CENTRAL ILLINOIS LATER THIS MORNING AND
ACROSS THE ENTIRE AREA DURING THE AFTERNOON. WITH PARTIAL SUNSHINE
ALLOWING FOR RAPID DESTABILIZATION AND NO MID-LEVEL CAPPING IN
PLACE...STORMS WILL READILY DEVELOP ALONG THE ADVANCING BOUNDARY.
GUSTY WINDS...FREQUENT LIGHTNING...AND LOCALLY HEAVY RAINFALL WILL
BE LIKELY. OUTSIDE OF STORMS...IT WILL BE ANOTHER VERY WARM AND
HUMID DAY WITH HIGHS TOPPING OUT IN THE UPPER 80S AND LOWER 90S.
HEAT INDEX READINGS WILL AGAIN RISE WELL INTO THE 90S...BUT SHOULD
BE A BIT LOWER THAN YESTERDAY DUE TO ADDITIONAL CLOUD COVER.

LOW-LEVEL JET IS EXPECTED TO SHIFT EASTWARD TONIGHT...RUNNING FROM
THE SOUTHERN PLAINS DIRECTLY INTO CENTRAL ILLINOIS. AS A
RESULT...NUMEROUS SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP
ON THE NOSE OF THE JET...ESPECIALLY IN THE VICINITY OF THE SYNOPTIC
FRONTAL BOUNDARY THAT WILL BE SAGGING SOUTHWARD INTO NORTH-CENTRAL
ILLINOIS. WILL THEREFORE CARRY LIKELY POPS ACROSS THE NORTHERN HALF
OF THE KILX CWA...WITH CHANCE POPS FURTHER SOUTH. LOCALLY HEAVY
RAINFALL WILL AGAIN BE A GOOD BET. FLASH FLOOD WATCH MAY NEED TO BE
CONSIDERED BY LATER SHIFTS IF IT BECOMES APPARENT ANOTHER NOCTURNAL
MCS WILL DEVELOP AND MOVE INTO THE AREA LATE TONIGHT INTO MONDAY. AT
THIS TIME...ENOUGH UNCERTAINTY EXISTS TO PREVENT WATCH ISSUANCE.
WILL INSTEAD MENTION POTENTIAL FOR HEAVY RAINFALL IN ZONES AND HWO.

SHOWERS AND THUNDERSTORMS WILL BE WIDESPREAD ACROSS CENTRAL ILLINOIS
ON MONDAY...AS SLOW-MOVING FRONT INTERACTS WITH A MOISTURE-RICH
ENVIRONMENT. PRECIPITABLE WATER VALUES WILL REMAIN AROUND 2 INCHES
THROUGH MONDAY...SO MAIN CONCERN IS FOR HEAVY RAINFALL...ALTHOUGH
PERIODIC ROUNDS OF STRONG TO SEVERE STORMS WILL BE POSSIBLE AS WELL.
WILL CARRY LIKELY POPS ACROSS THE BOARD ON MONDAY AND HIGH CHANCE
POPS INTO MONDAY NIGHT. BY TUESDAY...FRONT BEGINS TO SHIFT SOUTHWARD
INTO THE OHIO RIVER VALLEY...HOWEVER MODELS CONTINUE TO INDICATE
WAVES RIDING ALONG THE BOUNDARY THAT WILL KEEP RAIN CHANCES ALIVE
INTO TUESDAY NIGHT BEFORE THE FRONT FINALLY GETS PUSHED FURTHER
SOUTH AND EAST.

LONG TERM...WEDNESDAY THROUGH SATURDAY
DRIER WEATHER ARRIVES DURING THE EXTENDED AS A ZONAL UPPER PATTERN
DEVELOPS ACROSS THE CONUS. NEXT FRONT LOOKS TO ARRIVE ACROSS
ILLINOIS BY LATE THURSDAY NIGHT INTO FRIDAY...ALTHOUGH WITH FAST
FLOW ALOFT...IT WILL NOT LINGER ACROSS THE REGION AS THE CURRENT
FRONT HAS DONE...SO RAIN CHANCES WILL BE LIMITED. AT THIS
TIME...WILL ONLY MENTION SLIGHT CHANCE POPS MAINLY DURING THE DAY
FRIDAY...WITH DRY WEATHER RETURNING BY THE WEEKEND.

WOODFORD-
1107 AM CDT SUN JUN 13 2010

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL
ILLINOIS...EAST CENTRAL ILLINOIS AND SOUTHEAST ILLINOIS.

.DAY ONE...THIS AFTERNOON AND TONIGHT

THERE IS A RISK FOR SEVERE THUNDERSTORMS THIS AFTERNOON THROUGH
EARLY EVENING ACROSS CENTRAL ILLINOIS. ADDITIONAL SEVERE WEATHER
WILL BE POSSIBLE AGAIN IN THE OVERNIGHT HOURS EARLY MONDAY
MORNING. AN OUTFLOW BOUNDARY FROM PREVIOUS STORMS LOCATED OVER
EXTREME SOUTHERN ILLINOIS WILL MOVE NORTHEAST AS A WARM FRONT THIS
AFTERNOON. MEANWHILE...A DISTURBANCE OVER THE CENTRAL PLAINS THIS
MORNING WILL MOVE EAST ACROSS NORTHERN MISSOURI TOWARD WESTERN
ILLINOIS. THUNDERSTORMS ARE EXPECTED TO INCREASE OVER CENTRAL
ILLINOIS WITH THE APPROACH OF BOTH FEATURES DURING MIDDAY AND
CONTINUE INTO MID EVENING. ANY THUNDERSTORMS THAT DEVELOP WILL
HAVE THE POTENTIAL TO PRODUCE WIND DAMAGE AS WELL AS LOCALLY
TORRENTIAL RAINFALL. IN ADDITION...VERY FREQUENT DANGEROUS
LIGHTNING AND HAIL MAY ALSO OCCUR. THIS BATCH OF STORMS IS
EXPECTED TO WEAKEN AND MOVE EAST OF THE AREA AROUND SUNSET.

ADDITIONAL THUNDERSTORM DEVELOPMENT WILL BE LIKELY AGAIN OVER
SOUTHERN IOWA AND NORTHERN MISSOURI TONIGHT...AND THIS ACTIVITY
WILL MOVE EAST INTO CENTRAL ILLINOIS AFTER MIDNIGHT. ONCE
AGAIN... DAMAGING WINDS AND VERY HEAVY RAIN WILL BE THE PRIMARY
THREATS.

THE POTENTIAL FOR FLASH FLOODING WILL EXIST OVER CENTRAL ILLINOIS
THIS AFTERNOON AND TONIGHT. THE LOCATIONS OF THE HIGHEST THREAT WILL
DEPEND ON HOW THE THUNDERSTORMS INITIALLY EVOLVE TO OUR WEST...AND
THEIR IMPACT ON THE WARM FRONT THAT WILL BE IN THE AREA. SOME
UNCERTAINTY EXISTS WITH THESE DETAILS THIS FAR IN ADVANCE. KEEP
ABREAST OF THE LATEST FORECASTS AS THE SITUATION UNFOLDS.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

THE WARM FRONT OVER ILLINOIS LATER TODAY AND TONIGHT WILL TURN
NEARLY STATIONARY OVER THE AREA...WITH SEVERAL CLUSTERS OF
THUNDERSTORMS EXPECTED FROM MONDAY THROUGH TUESDAY. AS WILL BE THE
CASE TODAY...A RISK OF WIND DAMAGE AND VERY HEAVY RAINFALL WILL
EXIST WITH THESE STORMS. MULTIPLE PERIODS OF HEAVY RAIN WILL LIKELY
CAUSE RISES ON MANY RIVERS AND STREAMS...AS WELL AS FLOODING OVER
OTHER LOW AREAS AWAY FROM RIVERS. STAY INFORMED OF LATER FORECASTS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON AND TONIGHT.
