AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
640 AM CDT TUE JUN 12 2007

...UPDATE TO AVIATION...

.DISCUSSION...

SHOWERS AND THUNDERSTORMS THAT FORMED IN AN AREA OF WEAK ISENTROPIC
LIFT ALONG A BOUNDARY LEFT FROM THE STORMS MONDAY ARE BEING
PERSISTENT THIS MORNING. HEAVY RAINFALL IS OCCURRING WITH RADAR
ESTIMATES OF 3-5 INCHES HAVING FALLEN SO FAR. OF SOME CONCERN IS
THAT 0-3KM MUCAPES OVERNIGHT REMAINED IN THE 1000-1500J/KG RANGE IN
THE AREA OF CURRENT CONVECTIVE DEVELOPMENT. THIS INSTABILITY IS
BEING AIDED BY A WEAK BUT PRESENT LLJ AROUND 15KTS AND WAA NOTED AT
925MB. WHILE THE LLJ WILL DISSIPATE IN THE NEXT FEW HOURS...THE WAA
SHOULD CONTINUE AS THE SUN COMES UP WITH CAPES INCREASING TO AROUND
2000J/KG. THIS COULD BE ENOUGH TO KEEP THE STORMS GOING INTO THE
LATE MORNING AND AFTERNOON WITH A POSSIBLE TRANSITION TO MARGINALLY
SEVERE THUNDERSTORMS ALONG THE MO/KS STATE LINE. THE GREATEST THREAT
WOULD BE WIND GUSTS TO 60MPH AND HAIL TO QUARTER SIZE. IN
ADDITION...HEAVY RAINFALL WILL REMAIN A THREAT ACROSS THOSE AREAS
THAT HAVE ALREADY RECEIVED FLOODING RAINS THE PAST 48 HOURS.

.PREV DISCUSSION.../246 AM CDT TUE JUN 12 2007/

ISOLATED AREA OF HEAVY RAINFALL WITH SOME ASSOCIATED LIGHTNING
CONTINUES TO DEVELOP ALONG ONE OF SEVERAL MESOSCALE BOUNDARIES
ACROSS THE OZARKS. WEAK ISENTROPIC LIFT AND AN ARM OF THE LOW LEVEL
JET LOOK LIKE THEY ARE AIDING IN SUSTAINING THIS CONVECTION. SHOULD
SEE THIS ACTIVITY CONTINUE TO AROUND DAWN WHEN THE LLJ WEAKENS AND
THE WEAK VORTICITY CENTER IN THE MID LEVELS SHIFT EAST OUT OF THE
REGION. WITH THIS SAID...MOST AREAS SHOULD REMAIN DRY TODAY...BUT
JUST ABOUT ANY PLACE IS PRONE TO SEEING A POP-UP SHOWER OR
THUNDERSTORM AS DAY TIME HEATING AND LEFT OVER BOUNDARIES IMPACT
THE MOIST AND UNSTABLE AIRMASS IN PLACE. AFTERNOON MUCAPE VALUES
ACROSS THE SOUTHWESTERN CWA ARE PROGGED TO BE AROUND 2000J/KG WHICH
SHOULD BE SUFFICIENT TO KEEP SHOWERS AND THUNDERSTORMS OVER THE AREA
THROUGH TONIGHT.

FORECAST CHALLENGE AFTER TODAY REMAINS THE POSSIBILITY OF ISOLATED
TO WIDELY SCATTERED SEVERE WEATHER LATE THIS AFTERNOON AND EARLY
EVENING. THEN PRECIP CHANCES THROUGH THE WEEK.

GFS/ECMWF/WRF-NAM HAVE ALL BEEN DOING A PRETTY GOOD JOB WITH THE
FORECAST TO THIS POINT. HIGHLY AMPLIFIED RIDGE FROM THE GREAT LAKES
INTO TEXAS WILL REMAIN IN GENERALLY THE SAME PLACE INTO FRIDAY AS
THE TROUGH OVER THE WEST DEEPENS AND LIFTS OVER THE RIDGE DURING THE
WEEKEND. BLOCKING UPPER LEVEL LOW OVER THE EAST COAST REMAINS IN
PLACE WHICH HELPS KEEP THE RIDGE IN ANCHORED OVER THE CENTER OF THE
COUNTRY. SEVERAL SUBTLE SHORT WAVES WILL LIKELY RIDE UP AND OVER THE
RIDGE DURING THE WEEK AS A CUT OFF LOW DEVELOPS OVER THE
SOUTHWEST....AS NOTED BY THE GFS. THIS WILL KEEP THE CHANCES OF
SHOWERS AND THUNDERSTORMS IN THE AREA...ESPECIALLY OVER EXTREME
WESTERN MISSOURI AND SOUTHEAST KANSAS. SADLY...THESE ARE THE AREAS
THAT RECEIVED RECORD RAINFALL OVER THE LAST 48 HOURS AND COULD DO
WITH A FEW DAYS OF DRY WEATHER. ANY RAIN THAT FALLS AT THIS POINT
WILL ONLY EXACERBATE THE CURRENT FLOODING.
