AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE QUAD CITIES IA IL
319 AM CDT TUE AUG 4 2009

.SYNOPSIS...
SOMEWHAT COMPLEX SFC PATTERN THIS MORNING. INITIAL COLD FRONT...WHICH
PUSHED INTO NORTHWEST CWA LATE YESTERDAY... HAS UNDERGONE
FRONTOLYSIS. MAIN COLD FRONT EXTENDS FURTHER NORTH FROM WESTERN WI
THROUGH SOUTHERN MN AND SOUTHEAST SD. MEANWHILE... SFC LOW WAS
LOCATED OVER NORTHERN KS WEST OF CONCORDIA (KCNK) WITH STATIONARY FRONT
EXTENDING EASTWARD ACROSS NORTHERN MO AND CENTRAL IL. THIS BOUNDARY
QUITE EVIDENT IN MSAS SFC LI AND THETA-E. DEEP MOISTURE HAS POOLED
NEAR AND SOUTH OF THE STATIONARY BOUNDARY WITH SFC DEWPTS IN L/M 70S
AND H85 DEWPTS OF 15-17C... WHILE STRONG INSTABILITY NOTED WITH
MLCAPES OF 3000-4000 J/KG WITH PLENTY OF SHEAR WITH 0-6KM BULK SHEAR AT
30-40 KTS. CLUSTER OF SEVERE STORMS HAS DEVELOPED ACROSS FAR SW IA AND
NW MO AND DRIFTING E... WITH ADDITIONAL ACTIVITY FURTHER SOUTH INTO
NE KS. IN ADDITION... MCS WAS ADVANCING SE THROUGH CENTRAL NE AHEAD OF
MID LEVEL SHORTWAVE. NEW CONVECTION HAS RECENTLY DEVELOPED OVER SOUTHEAST
IA AND SHOWING GOOD GROWTH. OTHERWISE...MOISTURE POOLING ACROSS CWA AND
NEAR CALM/CALM WINDS HAS RESULTED IN PATCHY DENSE FOG EARLY THIS MORNING.
..05..

&&

.SHORT TERM...TODAY AND TONIGHT...
MAIN FOCUS IS WITH CONVECTIVE TRENDS AND ATTENDANT POPS/SEVERE POTENTIAL.

MONITORING TSTM CLUSTER OVER SW IA AND NW MO AS IT SLIDES E. RUC 310K SFC
DEPICTS ACTIVITY QUITE WELL AND SUPPORTS UPSCALE GROWTH TO MCS SLIDING
EASTWARD THIS MORNING AS 30+ KT LOW LEVEL JET VEERS AND IMPINGES ON THE
BAROCLINIC ZONE DRAPED ACROSS NORTHERN MO. PRESENCE OF CAPPING
INVERSION MUDDIES PICTURE A BIT AND POTENTIAL FOR STORMS TO DIVE MORE TO
THE SOUTH FEEDING INTO BEST INSTABILITY AND HIGH THETA-E AIR. NONETHELESS
WITH VEERING JET AND WARM ADVECTION IT WOULD APPEAR LIKELY THAT THE
ACTIVITY WILL DEVELOP EASTWARD AND IMPACT SOUTHERN TIER TO TWO TIERS OF
COUNTIES THIS MORNING AS ALSO SUGGESTED BY 4KM WRF WHICH HANDLED THE
CONVECTION (OR LACK OF) YESTERDAY THE BEST. GIVEN DEGREE OF INSTABILITY
WITH MLCAPES IN EXCESS OF 3000 J/KG AND 30-40 KTS OF BULK SHEAR...
POTENTIAL FOR SEVERE WX WITH STORMS IN FORM OF LARGE HAIL AND IF CAN BECOME
SFC BASED THEN DAMAGING WINDS. VERY HEAVY RAIN AND FLASH FLOODING A CONCERN
AS WELL GIVEN COPIOUS AMOUNTS OF MOISTURE WITH PW/S OF 1.4 TO 1.6.
SFC FRONT ACROSS WI AND MN TO SLIDE SE AND ACROSS CWA TODAY EXITING FAR
SOUTH EARLY EVE. THIS BOUNDARY MAY BE FOCUS FOR ISOLD/SCT STORMS THIS AFTN
MAINLY FROM QUAD CITIES SE. HIGHS WILL BE DEPENDENT ON DURATION OF
CONVECTIVE DEBRIS AND FEELING IS SHOW BE AROUND MOST OF MORNING CENTRAL
TO SOUTH... SO STAYED SOMEWHAT CONSERVATIVE ON MAXES WITH WIDESPREAD
L/M 80S. FEW SHRA/TSRA MAY LINGER EARLY EVE FAR SOUTH. OTHERWISE...
COOLER AND DRIER AIR TO OOZE IN. ADDITIONAL STORMS EXPECTED TO THE WEST
AND SOUTHWEST OF CWA ALONG BAROCLINIC ZONE. LOWS COOLEST IN NORTH AND
WARMEST SOUTH... AND ANTICIPATE 10-15 DEG GRADIENT ACROSS CWA.  ..05..

.LONG TERM...WEDNESDAY THROUGH NEXT MONDAY...
WEDNESDAY AND THURSDAY...OPERATIONAL MODELS SIMILAR IN KEEPING
FRONTAL BOUNDARY AND BULK OF THUNDERSTORMS SOUTH OF HIGHWAY 34 AND
ON INTO MO WEDNESDAY INTO THURSDAY. TEMPERATURES SHOULD REMAIN ABOUT
NORMAL FOR EARLY AUGUST. WILL CONTINUE WITH SMALL POPS.

THURSDAY NIGHT AND FRIDAY...DEEP TROUGH MOVES INTO THE WESTERN
UNITED STATES WHICH IN TURN BEGINS BUILDING AN UPPER LEVEL RIDGE
INTO THE MID MISSISSIPPI VALLEY. WITH CYCLOGENESIS TAKING PLACE IN
THE PLAINS LOW LEVEL JET WILL STRENGTHEN. OPERATIONAL MODELS MORE OR
LESS HINT AT A RATHER LARGE MCS DEVELOPING THURSDAY NIGHT ACROSS
IA...BUT REMAINING MAINLY WEST OF THE DVN CWA. THE 00Z HI-RES ECMWF
SUGGESTS MCS AFFECTING MUCH OF THE DVN CWA ON FRIDAY AS LOW LEVEL
JET IMPINGES ON THE WARM FRONT LIFTING NORTHEAST ACROSS THE REGION.
DEPENDING ON HOW THE PARAMETERS COME TOGETHER LOOKING AT POTENTIAL
FOR SEVERE WEATHER AND HEAVY RAIN. HAVE RAISED POPS INTO THE 30 TO
40 PERCENT RANGE. DEPENDING ON HOW WIDESPREAD THIS POTENTIAL MCS
BECOMES IT COULD EASILY WRECK HAVOC WITH TEMPERATURES.

THIS WEEKEND...WITH CONTINUED SOUTHERLY FLOW AND BUILDING
HEIGHTS...WARM FRONT WILL BE LIFTED WELL TO THE NORTH OF THE CWA.
OPERATIONAL MODELS SIMILAR WITH SHOWING A STRONGLY CAPPED AND HOT
AIRMASS OVER THE REGION. 850 MB TEMPERATURES PROGGED AT ABOUT +24C
WITH 700 TEMPS AT +14C. WITH PLENTY OF SUNSHINE TEMPS SHOULD SOAR
WELL INTO THE 90S WITH DEWPOINTS 70+. HEAT INDICES EXPECTED TO REACH
INTO THE 100 TO NEAR 110 RANGE...NUMBERS WE HAVENT SEEN SINCE THE
LAST WEEK OF JUNE. HEAT ADVISORIES OR EXCESSIVE HEAT WARNINGS MAY BE
REQUIRED AS WE GET CLOSER TO THE WEEKEND. IF CONFIDENCE IS HIGH
ENOUGH LATER SHIFTS MAY NEED TO CONSIDER AN EXCESSIVE HEAT WATCH.

EARLY NEXT WEEK...BOTH THE GFS AND HI-RES ECMWF INDICATE COLD FRONT
TO MOVE THROUGH THE REGION ABOUT MONDAY OR MONDAY NIGHT...
TEMPORARILY RETURNING SOMEWHAT COOLER TEMPERATURES. THE HOT DOME
GETS SHOVED BACK WEST INTO THE PLAINS...BUT EXPECTING THE HEAT TO
EVENTUALLY RETURN.

..HAASE..

&&

.AVIATION...
PATCHY FOG WILL BE FOUND ACROSS THE TERMINALS UNTIL MID MORNING WITH
VSBYS VARYING FROM IFR TO MVFR WITH PERIODS OF LIFR ESPECIALLY AT
KDBQ AND KCID. SHOWERS AND THUNDERSTORMS WILL BE FOUND THIS MORNING
NEAR AND JUST NORTH OF STATIONARY FRONT OVER NORTHERN MO. THIS
ACTIVITY MAY IMPACT KBRL AND POSSIBLY IN VICNITY AS FAR NORTH AS
KMLI. SFC COLD FRONT TO SHIFT ACROSS THE TERMINALS TODAY WITH WINDS
VEERING TO NORTHERLY 5-10 KTS AND PERSISTING TONIGHT. BANKING ON
DRIER AIR ADVECTING IN WITH NORTHERLY WINDS TO PRECLUDE ANY MENTION
OF FOG IN TERMINALS TONIGHT.  ..05..

1050 AM CDT MON AUG 3 2009

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...THIS AFTERNOON AND TONIGHT

AFTERNOON TEMPERATURES ARE EXPECTED TO SOAR TO NEAR 90 SOUTH OF
HIGHWAY 34...WITH HEAT INDICES IN THE LOWER TO MIDDLE 90S. PEOPLE
WORKING OUTDOORS SHOULD TAKE PRECAUTIONS IN THE HEAT.

A SLIGHT RISK OF SEVERE THUNDERSTORMS EXISTS LATE THIS AFTERNOON AND
EVENING FOR LOCATIONS MAINLY ALONG AND SOUTH OF INTERSTATE 80.
ISOLATED TO SCATTERED SUPERCELL THUNDERSTORMS WILL RAPIDLY DEVELOP
LATE THIS AFTERNOON AND EVENING AHEAD OF A WEAK COLD FRONT MOVING
SOUTHEAST INTO THE REGION. VERY LARGE DESTRUCTIVE HAIL OF GOLF BALL
TO TENNIS BALL SIZE AND DAMAGING WINDS OF 60 TO 70 MPH ARE THE MAIN
THREATS. THE STORMS SHOULD EVENTUALLY BECOME MORE WIDESPREAD TONIGHT
ALONG AND SOUTH OF HIGHWAY 34...WITH LOCALLY HEAVY RAIN POSSIBLE.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

THUNDERSTORMS MAY PERSIST INTO EARLY TUESDAY MORNING SOUTH OF
HIGHWAY 34. THE MAIN THREAT WILL BE LIGHTNING AND LOCALLY HEAVY
RAINFALL.

THERE IS A CHANCE OF THUNDERSTORMS REDEVELOPING SOUTH OF INTERSTATE
80 TUESDAY AFTERNOON. SOME OF THE STORMS COULD BECOME SEVERE
OVER SOUTHEAST IOWA...WEST CENTRAL ILLINOIS AND NORTHEAST MISSOURI.
THE MAIN THREATS WILL BE LARGE HAIL AND DAMAGING WINDS.

THE FRONT IS EXPECTED TO STALL ACROSS CENTRAL PORTIONS OF MISSOURI
AND ILLINOIS WEDNESDAY INTO THURSDAY...SHIFTING THE MAIN
POTENTIAL FOR SEVERE WEATHER WELL SOUTH AND WEST OF THE OUTLOOK
AREA.

AS THE FRONT RETURNS NORTH LATE THURSDAY THROUGH FRIDAY...THUNDERSTORM
CHANCES WILL BE ON THE INCREASE. EARLY INDICATIONS SUGGEST SOME
STRONG TO SEVERE STORMS AND HEAVY RAINFALL WILL BE POSSIBLE...BUT
IT IS TOO EARLY TO DETERMINE MORE SPECIFIC SEVERE WEATHER THREATS.

ALTHOUGH MUCH OF THIS SUMMER HAS BEEN COOLER THAN NORMAL...CURRENT
INDICATIONS SUGGEST THAT A SIGNIFICANT CHANGE TO HOT AND HUMID
CONDITIONS WILL OCCUR NEXT WEEKEND...WITH WIDESPREAD HIGHS IN THE
90S AND HEAT INDICES APPROACHING OR EXCEEDING 100 DEGREES.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE REQUIRED LATE THIS AFTERNOON AND INTO
EARLY TONIGHT.
