AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
425 AM CDT THU JUN 5 2008

.UPDATE...
MONITORING RECENT RADAR TRENDS...FLASH FLOODING POTENTIAL ACROSS
THE SE CWFA APPEARS TO HAVE ENDED. BULK OF MCS CLUSTERS MOVING
OUT OF S CENTRAL IA ARE DISSIPATING AT THE SOUTHERN END AND
LIFTING NORTHEAST. ONLY ISOLATED SHOWERS AND FEW THUNDERSTORMS
WERE SEEN IN ELEVATED CONVECTION RIDING NE ACROSS NE MO INTO W
CENTRAL IL...WHERE WARMING MID LEVEL TEMPS ON LAPSE SOUNDINGS
WAS INCREASING THE CAP. HAVE UPDATED FLASH FLOOD WATCH TO REMOVE
FAR SE IA...NE MO AND ALL BUT FAR NW IL. EVEN IF STORMS DO DEVELOP
OR INCREASE INTO THIS AREA...THE ACTIVITY SHOULD BE PROGRESSIVE
AND LESS PRONE TO TRAINING OF STORM COMPLEXES THAT HAS BEEN SEEN
ALONG AND NORTH OF THE WARM FRONT. E CENTRAL IA INTO FAR NW IL STILL
LOOKS TO BE AT GREATEST RISK FOR SHORT TERM FLASH FLOODING AND
CONTINUE WATCH THERE THROUGH 10 AM. ..SHEETS..

.AVIATION...
STRONG TO SEVERE TSRA MVNG RAPIDLY NE THROUGH KCID AND KDBQ EARLY
THIS MORNING. STORMS OVER SCNTRL IA MAY HOLD TOGETHER LONG ENUF TO
IMPACT KMLI/KBRL IN THE 12Z TO 15Z TIME FRAME. EXPECT IFR
CONDITIONS WITH TSRA AND WND GUSTS LIKELY 35 TO 45KTS. WARMING MID
LEVELS THIS MORNING SHOULD DECREASE TSRA THREAT FOR KBRL AFTER 15Z
AND AT KMLI AFT 18Z. TSRA THREAT AT KMLI/KBRL SHOULD BE LOW THE
REST OF THE AFTERNOON AND EVENING. WARM FRONT APPEARS TO STALL
JUST S OF KCID AND KDBQ THROUGH EARLY AFTERNOON WHICH SUGGESTS AT
LEAST SCATTERED SHRA/TSRA TO REMAIN NEAR THOSE TAFS SITES THROUGH
MID AFTERNOON. WARM FRONT TO PUSH N OF KCID/KDBQ DURING THE LATE
AFTERNOON OR EARLY EVENING WHICH WILL PROVIDE A BREAK IN THE TSRA
DURING THE LATE EVENING AND EARLY MORNING HOURS. STRONG TO SEVERE
TSRA EXPECTED TO DEVELOP OVER CENTRAL IA LATE TONIGHT...MAY MAKE
IT INTO KCID AFTER 06Z. ...DLF..

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF NORTH CENTRAL
ILLINOIS...NORTHWEST ILLINOIS...WEST CENTRAL ILLINOIS...EAST
CENTRAL IOWA...NORTHEAST IOWA...SOUTHEAST IOWA AND NORTHEAST
MISSOURI.

.DAY ONE...TODAY AND TONIGHT

AN EMERGENCY MANAGER CONFERENCE CALL HAS BEEN SCHEDULED FOR 130 PM
TODAY...FOR AREAS ALONG THE MISSISSIPPI RIVER AND WESTWARD. THE
TOPIC OF THE CONFERENCE CALL WILL BE AN UPDATE ON THE FLOODING AND
SEVERE WEATHER THREATS OVER THE NEXT FEW DAYS.

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS OVER THE ENTIRE
AREA THROUGH TONIGHT.

A STATIONARY FRONT ACROSS NORTHERN MISSOURI AND CENTRAL ILLINOIS
WILL BE THE FOCUS FOR THUNDERSTORM DEVELOPMENT TODAY. SCATTERED
THUNDERSTORMS ARE EXPECTED ALONG AND SOUTH OF INTERSTATE 80 THIS
MORNING. AN ISOLATED SEVERE STORM IS POSSIBLE...ESPECIALLY SOUTH
OF HIGHWAY 34...WITH PENNY SIZE HAIL AND DAMAGING WIND GUSTS.

THE RISK OF SEVERE THUNDERSTORMS WILL SPREAD NORTH THIS AFTERNOON
AND OVERNIGHT AS THE STATIONARY FRONT...BEGINS TO MOVE NORTH AS A
WARM FRONT. THE PRIMARY SEVERE THREAT WITH THE AFTERNOON AND
OVERNIGHT STORMS WILL BE DAMAGING THUNDERSTORM WINDS AND LARGE
HAIL. AN ISOLATED TORNADO IS ALSO POSSIBLE...MAINLY DURING THE
LATE AFTERNOON AND EVENING HOURS.

THE POTENTIAL FOR MORE FLASH FLOODING EXISTS OVER THE AREA THROUGH
TONIGHT. HEAVY RAINS OVER THE PAST SEVERAL DAYS HAS RESULTED IN
SATURATED SOILS OVER MUCH OF THE AREA. ANY MODERATE TO HEAVY RAINS
TODAY AND TONIGHT WILL RESULT IN RAPID RUNOFF AND FLASH FLOODING.
A FLASH FLOOD WATCH IN EFFECT WEST OF A DUBUQUE IOWA...MACOMB
ILLINOIS LINE TODAY AND TONIGHT.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THURSDAY INTO
THURSDAY NIGHT ROUGHLY NORTH OF A LINE FROM SIGOURNEY...THROUGH
CEDAR RAPIDS...TO FREEPORT ILLINOIS. THE MAIN SEVERE WEATHER THREATS
WILL BE DAMAGING WINDS AND LARGE HAIL. A FEW NON-SEVERE
THUNDERSTORMS WILL BE POSSIBLE DURING THE DAY THURSDAY FROM HIGHWAY
34 NORTH TO THIS AXIS. DUE TO HIGH LEVELS OF MOISTURE IN THE
ATMOSPHERE...THERE WILL BE A CONTINUED RISK OF HEAVY RAINFALL WITH
ANY THUNDERSTORM.

ON FRIDAY...THE STORM PREDICTION CENTER HAS PLACED THE ENTIRE
OUTLOOK AREA UNDER A SLIGHT RISK OF SEVERE THUNDERSTORMS. THE MAIN
SEVERE WEATHER THREAT WILL BE DAMAGING WINDS AND HEAVY RAINFALL.
THERE IS ALSO A POTENTIAL FOR SUPERCELL THUNDERSTORMS CAPABLE OF
PRODUCING LARGE HAIL AND ISOLATED TORNADOES.

WITH THE GROUND SATURATED FROM RECENT HEAVY RAINS...ANY ADDITIONAL
HEAVY RAIN THROUGH THE PERIOD MAY LEAD TO FLASH FLOODING.

THERE IS A CHANCE FOR THUNDERSTORMS OVER ESPECIALLY THE NORTHWEST
HALF OF THE OUTLOOK AREA SATURDAY NIGHT THROUGH MONDAY. IT IS TOO
EARLY TO DETERMINE THE POTENTIAL FOR SEVERE WEATHER.

MINOR TO MAJOR FLOODING WILL CONTINUE ON MANY SEVERAL EASTERN IOWA
TRIBUTARY RIVERS...WITH MINOR FLOODING ALONG THE MISSISSIPPI RIVER
FROM GLADSTONE SOUTHWARD. MORE DETAILED INFORMATION CAN BE FOUND IN
THE LATEST FLOOD STATEMENT PRODUCT.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE REQUIRED TODAY AND TONIGHT.
