AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
1247 PM CDT SAT JUN 10 2006

.DISCUSSION...
QUASI-STATIONARY FRONT DRAPED ACROSS THE CWFA FROM SOUTH OF
KIRKSVILLE TO NEAR ST. LOUIS DOWN TO NEAR CAPE GIRARDEAU WILL BE THE
PRIMARY WEATHER-MAKER FOR THE NEXT 24-48 HOURS.  SHORT-RANGE MODEL
OUTPUT WAVES THE FRONT AROUND ACROSS THE CWFA WITH SEVERAL ROUNDS OF
CONVECTION FORMING ALONG IT THROUGH SUNDAY EVENING WHEN IT FINALLY
HEADS SOUTHWARD INTO ARKANSAS.  WHILE THE MODELS ARE IN FAIRLY GOOD
AGREEMENT ON THE POSITION OF THIS FRONT ON A SYNOPTIC SCALE...THERE
WILL DOUBTLESS BE 10-20 DEGREE TEMPERATURE DIFFERENCES ON EITHER
SIDE OF THE FRONT...AND NAILING DOWN ITS EXACT POSITION AS IT IS
WORKED OVER AND SHOVED AROUND BY CONVECTION IS IMPOSSIBLE.
THEREFORE...HAVE SIMPLY TRIED TO BLEND THE PREVIOUS FORECAST IN WITH
MOST UP-TO-DATE GUIDANCE FOR THIS PACKAGE.  I WILL DOUBTLESS BE VERY
WRONG AT VARIOUS TIMES IN VARIOUS PLACES ALL ACROSS THE AREA AS THE
FRONT MOVES BACK AND FORTH THROUGH SUNDAY.

PRECIPITATION FORECAST IS ALSO PROBLEMATIC TIL THE FRONT MOVES OUT
OF THE AREA SUNDAY EVENING.  I AM FAIRLY CONFIDENT THAT THE MAJORITY
OF THE AREA WILL AT LEAST SEE SOME RAIN THROUGH SUNDAY NIGHT...BUT
TIMING THE VARIOUS WAVES OF PRECIPITATION...RAINFALL AMOUNTS/HEAVY
RAIN POTENTIAL...AND SEVERE WEATHER POTENTIAL ARE THE REAL
CHALLENGES.  THE HIGHEST POPS SHOULD OVER-SPREAD THE AREA FROM THE
NORTH TODAY AND TONIGHT AS THE LOW LEVEL BAROCLINIC ZONE TIGHTENS
ALONG THE MISSOURI AND IOWA BORDER IN RESPONSE TO A DECENT 850MB JET
RUSHING IN FROM THE SOUTHERN PLAINS...AND COOLER AIR FILTERING IN
FROM THE NORTH AS A STRONG CANADIAN RIDGE BUILDS INTO THE GREAT
LAKES.  THERE SHOULD BE ONGOING PRECIPITATION ALONG AND NORTH OF THE
BAROCLINIC ZONE THROUGH THE PERIOD...WITH WAVES OF CONVECTION
FORMING ON THE FRONT DURING THE LATE AFTERNOON OR EARLY EVENING
DURING THE MOST UNSTABLE PART OF THE DAY.  COULD SEE SOME DAMAGING
WINDS AND/OR LARGE HAIL DURING THE LATE AFTERNOON OR EARLY EVENING
BOTH TODAY AND SUNDAY--INDEED SPC HAS US OUTLOOKED IN A SLIGHT RISK
FOR BOTH DAY 1 AND DAY 2--BUT I THINK WELL SEE THE THREAT
TRANSITION FROM SEVERE WEATHER TO HEAVY RAIN DURING THE OVERNIGHT
HOURS AS STORMS BECOME MORE ELEVATED.  P-WATS ACROSS THE AREA ARE
ALREADY AT 100% OF CLIMATOLOGY OR BETTER ACROSS THE REGION AND THAT
SHOULD INCREASE AS THE LOW LEVEL JET CONTINUES TO PUMP MORE GULF
MOISTURE UP INTO THE MISSISSIPPI VALLEY.

MANY THANKS ONCE AGAIN TO SURROUNDING WFOS THIS MORNING FOR
COORDINATION AND COLLABORATION

CARNEY

.AVIATION...
FOR THE 18Z TAFS...
FRONT BISECTING THE CWA AT THE MOMENT...ALIGNING ITSELF PARALLEL
TO INTERSTATE 70. LOOK FOR SEVERAL ROUNDS OF STRONG TO SEVERE
THUNDERSTORMS TO OCCUR LATE THIS AFTERNOON AND THIS EVENING ALONG
THIS BOUNDARY. A CONTINUED THREAT OF RAIN...POSSIBLY
HEAVY...OVERNIGHT ALONG THIS CORRIDOR WHERE BROAD LOW LEVEL JET
WILL INTERSECT STALLED FRONTAL BOUNDARY. WINDS WILL REMAIN OUT OF
THE EAST TO THE NORTH OF THE FRONT AND SOUTHWEST TO THE SOUTH.

CONVECTIVE WIND GUSTS ABOVE 60 MPH AND HAIL UP TO THE SIZE OF

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF EASTERN AND
CENTRAL MISSOURI AS WELL AS SOUTHWEST ILLINOIS.

.DAY ONE...TONIGHT

THUNDERSTORMS WILL RAPIDLY DEVELOP THIS EVENING ALONG A STATIONARY
BOUNDARY THAT IS ORIENTATED FROM WEST TO EAST ACROSS MISSOURI AND
ILLINOIS. SEVERAL ROUNDS OF STRONG TO POTENTIALLY SEVERE THUNDERSTORMS
ARE EXPECTED THIS EVENING AND OVERNIGHT. THE GREATEST THREAT FROM
THE SEVERE THUNDERSTORMS WILL BE DAMAGING WINDS IN EXCESS OF 60
MPH AND LARGE HAIL UP TO THE SIZE OF GOLF BALLS.

IN ADDITION TO THE SEVERE WEATHER THREAT...THESE CLUSTERS OF
THUNDERSTORMS ARE EXPECTED TO MOVE REPEATEDLY ALONG THE FRONTAL
BOUNDARY WHICH WILL LIE PARALLEL TO INTERSTATE 70...LEADING TO AN
ENHANCED THREAT OF FLASH FLOODING ACROSS CENTRAL AND EAST CENTRAL
MISSOURI AS WELL AS SOUTHWEST ILLINOIS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

PERIODS OF THUNDERSTORMS WILL CONTINUE INTO SUNDAY WITH HEAVY
RAINFALL AND FLASH FLOODING POSSIBLE EARLY SUNDAY MORNING.
ADDITIONAL THUNDERSTORM DEVELOPMENT IS EXPECTED SUNDAY AFTERNOON
ALONG THE STATIONARY FRONT...WITH A SLIGHT RISK OF SOME OF THESE
THUNDERSTORMS BECOMING SEVERE WITH LARGE HAIL AND DAMAGING WINDS.

THE FRONTAL BOUNDARY WILL SINK SOUTH OF THE REGION SUNDAY
NIGHT...ENDING THE THREAT OF THUNDERSTORMS ACROSS THE REGION.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS ARE ASKED TO RELAY ALL SEVERE WEATHER REPORTS AND FLASH
FLOODING TO THE NATIONAL WEATHER SERVICE.
