AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ST LOUIS MO
341 PM CDT THU JUL 8 2010

.DISCUSSION...
/341 PM CDT THU JUL 8 2010/

 ...SYNOPSIS...
SLOW MOVING COLD FRONT THAT HAS AFFECTED THE MIDWEST ALL WEEK
CONTINUES IT/S SLOW PROGRESSION S/E...CURRENTLY EXTENDING ALONG I-70
IN IL AND I-44 IN MO. NUMEROUS SHRA/TSTMS HAVE DEVELOPED ALONG AND
AHEAD OF THE BNDRY. PLUME OF SUBTROPICAL MOISTURE STILL EVIDENT ON
SAT IMAGE. LOWER DPS WILL BE SLOW TO FILTER INTO THE AREA AS SURFACE
OBS SHOW UPPER 60 DEGREE DPS WELL TO THE NORTH INTO SOUTHERN/EASTERN
IA AND NORTHERN IL.

...SHORT TERM (TONIGHT THRU SUNDAY)...
ANOTHER SHORTWAVE IN THE BROAD TROUGH ACROSS THE GREAT LAKES IS
PROGGED TO MOVE THROUGH THE AREA TONIGHT AND FRIDAY. THIS LOOKS TO
BE THE KICKER THAT WILL FINALLY PUSH THIS STUBBORN FRONT THROUGH THE
CWA BY FRIDAY NIGHT. CONVECTION SHOULD CONTINUE TO INCREASE IN
COVERAGE THIS AFTERNOON INTO THIS EVENING AS THE SHORT WAVE
APPROACHES AND THE ATMOSPHERE MAXIMIZES INSTABILITY. LOW SHEAR VALUES
AND A MOIST PROFILE LIMIT SVR POTENTIAL TO OUTFLOW DOMINATED
CLUSTERS. HAVE LIKELY POPS FROM THE STL METRO AND POINTS SOUTH AND
EAST OVERNIGHT...THEN CONFINED TO THE EASTERN OZARKS AND PARTS OF
SOUTHERN ILLINOIS ON FRIDAY.  THERE HAS BEEN LIMITED THUNDER WITH
THE ACTIVITY OVER THE PAST SEVERAL DAYS...CAN FIND NO REASON THERE
WILL BE AN INCREASE THROUGH FRIDAY. LACK OF THUNDER IS DUE TO WARM
CLOUD PROCESSES...WITH FREEZING LEVELS NEAR 15 KFT AND PWATS AOA 2
INCHES ON THE 12Z SOUNDINGS AT ILX AND SGF...THE CORES OF MOST OF
THESE CELLS HAVE BEEN BELOW 20 KFT.  THIS ALLOWS THEM TO BE VERY
EFFICIENT RAIN PRODUCERS.  THIS SHOULD BE THE CASE OVERNIGHT AND
THROUGH THE DAY TOMORROW.  HAVE INCLUDED HEAVY RAIN POTENTIAL IN THE
GRIDS AND WILL HIGHLIGHT IN THE HWO.

AFTER THE SHORTWAVE LIFTS OUT OF THE AREA FRIDAY...UPPER FLOW
TRANSITIONS TO NW FLOW AS SURFACE HIGH PRESSURE BUILDS INTO THE
MIDWEST FOR THE WEEKEND.  THIS WILL PROVIDE SEASONAL TEMPS WITH DPS
IN THE LOW/MID 60S ON SATURDAY.  SURFACE RIDGE PASSES OVERHEAD LATE
SATURDAY.  RETURN FLOW COMMENCES SUNDAY AS WINDS TURN SOUTHERLY AND
MOISTURE SLOWLY INCREASES THROUGH THE DAY WITH DPS APPROACHING 70 BY
SUNDAY EVENING. THIS SETS THE STAGE FOR THE NEXT 500MB IMPULSE TO
AFFECT THE AREA EARLY NEXT WEEK. WENT WITH A BLEND OF MOS GUIDANCE
THROUGH THE WEEKEND.  HAVE CONCERN THAT THE GUIDANCE...HENCE THE
FCST...MAY BE A LITTLE ON WARM SIDE SAT/SUN.  850 TEMPS ARE PROGGED
TO BE 14-16 DEGREES WHICH CORRESPONDS TO LOW/MID 80S.  COMBINE THAT
WITH A LIGHT NORTHERLY BREEZE AND UPPER 80S MAY BE TOUGH TO REACH.
THAT BEING SAID...IT IS MID JULY AND THERE WILL BE NEARLY FULL
INSOLATION...SO REALLY COULDN/T GO AGAINST GUIDANCE ATTM.

...LONG TERM (SUNDAY NIGHT THRU THURSDAY)...
MODELS IN DECENT AGREEMENT ABOUT BRINGING ANOTHER SHORT WAVE TROUGH
THROUGH THE MIDWEST EARLY NEXT WEEK.  THIS DRIVES A FRONT THROUGH
THE CWA MONDAY/NIGHT.  GIVEN STRENGTH OF PERSISTENT RIDGE TO OUR
SOUTH...NOT SURE HOW FAR SOUTH THIS FEATURE WILL MAKE IT BEFORE
STALLING OUT.  MOST MODELS HAVE IT REACHING THE I-70 CORRIDOR BEFORE
STALLING.  UNLIKE CURRENT COLD FRONT AFFECTING THE REGION..THIS
FRONT LOOKS TO LOOSE IT/S IDENTITY RATHER QUICKLY AND BECOME DIFFUSE
BY WEDNESDAY/NIGHT.  THEREFORE...ENDED SCATTERED POPS ON TUESDAY AND
SLIGHT CHANCE POPS ON WEDNESDAY FRO AREAS SOUTH OF I-70.

THE AREA GETS BACK INTO RETURN FLOW ON WEDNESDAY NIGHT/THURSDAY AS
THE UPPER RIDGE ATTEMPTS TO RESET.  AGAIN...DECENT MODEL AGREEMENT
THAT THE UPPER RIDGE TIRES TO EXTEND FROM THE SE US ALL THE WAY WEST
TO THE DESERT SW.  THIS PUTS US FIRMLY IN ZONAL FLOW WITH THE BEST
CORE OF WESTERLIES NEAR THE CANADIAN BORDER. WITH 850 TEMPS IN THE
18-22 DEGREE RANGE AND SURFACE DEWPOINTS NEAR 70...THE END OF NEXT
WEEK AND THE WKND LOOK TO BE WARM AND MUGGY.

.AVIATION...
/1214 PM CDT THU JUL 8 2010/

SCT SHOWERS AND ISOLATED THUNDERSTORMS SHOULD BECOME MORE NUMEROUS
THIS AFTERNOON ALONG AND AHEAD OF THE COLD FRONT WHICH IS NOW JUST
NORTH OF INTERSTATE 70. COULD SEE SOME MVFR CEILINGS AND
VISIBILITES INSIDE STRONGER SHOWERS/STORMS. OTHERWISE...DRIER AIR
WORKS ITS WAY INTO THE AREA LATE TONIGHT AND ON FRIDAY WITH
NORTHERLY WIND.

SPECIFICS FOR KSTL...
WILL SEE INCREASE IN CONVECTION THIS AFTERNOON/EVENING AS COLD
FRONT SLOWLY SAGS ACROSS AND SOUTH OF THE TERMINAL. LIGHT AND
VARIABLE WIND WILL BECOME NORTHERLY OVERNIGHT...WITH RAIN CHANCES
ENDING BY MORNING. CAN'T RULE OUT SOME TEMPORARY MVFR OR EVEN IFR
CONDITIONS INSIDE HEAVIER CONVECTION.
