AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
403 AM CDT SAT AUG 2 2003

.DISCUSSION...
UNSEASONABLY STRONG GREAT LAKES CYCLONE CONTINUES TO SIT AND SPIN
AND HAS CREATED SOME UNSETTLED WEATHER ACROSS THE NATIONS MID
SECTION THE LAST FEW HOURS.   THE APPROACH OF AN UPPER LEVEL SPEED
MAX AND STRONG 850 MB MOISTURE SURGE INTO SOUTHEAST KANSAS HAS
PROVIDED THE NECESSARY INGREDIENTS FOR STRONG TO SEVERE STORMS THIS
MORNING.  LOOK FOR STORMS TO CONTINUE THROUGH A GOOD PORTION OF
TODAY AND ALL FORECAST ELEMENTS IN THE FIRST PERIOD WILL BE THE PRIMARY
FORECAST CHALLENGE.

SHORT TERM (TODAY - MONDAY)
MESO ETA IS NOT QUITE AS AGGRESSIVE WITH PUSHING SURFACE BOUNDARY
THROUGH SOUTHERN MISSOURI AS PREVIOUS RUNS.  ETA IS CERTAINLY THE
MODEL OF CHOICE AND SHORT TERM FORECAST WILL BE WEIGHTED HEAVIEST
WITH THE MESO ETA OUTPUT.

THE INITIAL CHALLENGE IS THE ONGOING CONVECTION AND HOW THIS WILL
MODIFY TODAYS FORECAST.  CONVECTIVE CLUSTER SOUTH OF THE PLATEAU IS
FINALLY HEADING SOUTH TOWARD THE ARKANSAS STATE
LINE...HOWEVER...SCATTERED ACTIVITY HAS REDEVELOPED NORTH OF THE
MAIN COMPLEX.  OTHER CLUSTERS HAVE DEVELOPED OVER SOUTHERN KANSAS
AND THIS ACTIVITY WILL LIKELY AFFECT EXTREME SOUTHWEST MISSOURI
WITHIN THE FIRST PERIOD.  LOW LEVEL BOUNDARY HAS BECOME ALMOST
QUASI-STATIONARY AND MESO ETA SOUNDING PROGS SHOW SURFACE BASED
CAPES OF AROUND 3000 J/KG THIS AFTERNOON.  SO FIRST PERIOD FORECAST
WILL CONTAIN THUNDERSTORM CHANCES ACROSS THE BOARD FOR THIS MORNING
AND THIS AFTERNOON.

WITH WARM AND UNSTABLE AIRMASS LINGERING ACROSS SOUTHERN
MISSOURI...WILL HAVE TO INTRODUCE PRECIP CHANCES INTO SATURDAY NIGHT
AND SUNDAYS FORECAST AS WELL.  OVERALL SYNOPTIC PATTERN AMPLIFIES TO
A DEGREE...AND 200 MB SPEED MAX PIVOTS IN MORE OF A NORTH TO SOUTH
FASHION.  CWA REMAINS IN A STRONG AREA OF UPPER LEVEL DIFFLUENCE
POSITIONED UNDER THE LEFT EXIT REGION OF THIS FEATURE.  THIS IN
CONJUNCTION WITH A COUPLE OF DEVELOPING MID LEVEL DISTURBANCES WILL
PROVIDE ENOUGH FORCING FOR REDEVELOPMENT OF CONVECTION.

LONG TERM (TUESDAY - FRIDAY)...
TWO MAIN SYNOPTIC FEATURES CONTROLLING THE UPPER FLOW WILL GRADUALLY
SHIFT EAST NEXT WEEK.  ECMWF IS A LITTLE MORE AGGRESSIVE WITH
BUILDING IN THE UPPER RIDGE OVER THE HIGH PLAINS AND PROGRESSING
EASTERN CONUS TROUGH TOWARDS THE COAST.  IN EITHER CASE...THE
NATIONS MID SECTIONS REMAINS UNDER THE INFLUENCE OF NORTHWEST FLOW.

ONGOING EXTENDED FORECASTS LOOKS LIKE ITS IN GREAT SHAPE AND SEE NO
REASON TO MAKE ANY DRASTIC CHANGES.  CHALLENGES AS ALWAYS WILL EXIST
IN TIMING ANY DISTURBANCES RIDING DOWN THE NORTHWEST FLOW...WHICH
WILL BECOME MORE APPARENT WITH TIME.  TWEAKED TEMPS AND CLOUD COVER
SOME TO BLEND IN BETTER WITH SURROUNDING OFFICES.

.AVIATION...
CLUSTERS OF CONVECTION CONTINUE TO AFFECT AREAS OF SOUTHEAST KANSAS
AND THE SOUTHWEST MISSOURI THIS MORNING.  EXPECT THIS ACTIVITY TO
SLOWLY DRIFT SOUTHWARD AS THE MORNING PROGRESSES...POSSIBLY
REDEVELOPING THIS AFTERNOON.  A COLD FRONT WILL LINGER ACROSS THE
REGION THE NEXT 24 TO 48 HOURS...CONTINUING THUNDERSTORM CHANCES
INTO SUNDAY.

.SGF WATCHES/WARNINGS/ADVISORIES...
.MO...NONE.
.KS...NONE.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE SPRINGFIELD MO
1219 AM CDT SAT AUG 2 2003

THIS HAZARDOUS WEATHER OUTLOOK IS FOR THE MISSOURI OZARKS AND EXTREME
SOUTHEAST KANSAS.

.DAY ONE...SATURDAY.

WEATHER HAZARDS EXPECTED:

THUNDERSTORMS CONTAINING HAIL TO THE SIZE OF QUARTERS...WIND GUSTS
IN EXCESS OF 70 MPH...AND TORRENTIAL RAINS CONDUCIVE FOR FLASH
FLOODING.

AREAS AFFECTED AND TIMING:

ALL OF EXTREME SOUTHEAST KANSAS AND THE MISSOURI OZARKS THROUGH THE
OVERNIGHT HOURS.

DISCUSSION:

STRONG TO SEVERE THUNDERSTORMS WILL CONTINUE TO ERUPT ACROSS THE
REGION THROUGH THE PRE-DAWN HOURS.  THE COMBINATION OF A STRONG LOW
LEVEL MOISTURE SURGE AND AN APPROACHING JET MAX ALOFT WILL PROVIDE
NECESSARY INGREDIENTS FOR RAPIDLY DEVELOPING SEVERE THUNDERSTORMS.
THESE STORMS WILL LIKELY EVOLVE INTO A CLUSTER THE NEXT FEW
HOURS...AND THE TRAINING OF STORMS OVER SPECIFIC LOCATIONS IS
LIKELY.  THIS WILL LEAD TO INCREASED FLASH FLOOD POTENTIAL
ESPECIALLY OVER THE ROCKY TERRAIN OF THE OZARK HILLS.  STRONG
DIRECTION CHANGE WITH WINDS ALOFT WILL ALLOW SOME OF THESE STORMS TO
MAINTAIN ROTATING UPDRAFTS FOR LONG PERIODS OF TIME.  OTHER THAN
FLASH FLOODING...HAIL UP TO THE SIZE OF HALF DOLLARS AND STRONG WIND
GUSTS IN EXCESS OF 70 MPH WILL ACCOMPANY THE STRONGER STORMS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.

AN UPPER LEVEL DISTURBANCE WILL APPROACH THE REGION MONDAY NIGHT
INTO TUESDAY.  ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS WILL BE
POSSIBLE UPON PASSAGE OF THIS SYSTEM.  FREQUENT LIGHTNING AND
TORRENTIAL DOWNPOURS WILL BE THE PRIMARY HAZARDS FROM THIS ACTIVITY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL LIKELY BE REQUIRED OVER EXTREME SOUTHEAST
KANSAS AND THE MISSOURI OZARKS THROUGH MUCH OF THE EARLY MORNING
HOURS.
