AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
149 PM CDT WED APR 17 2013

.MESOSCALE DISCUSSION...
ISSUED AT 135 PM CDT WED APR 17 2013

18Z SPECIAL WEATHER BALLOON RELEASE SHOWING A VERY UNSTABLE
ATMOSPHERE PRIMED FOR STRONG TO SEVERE CONVECTION DEVELOPMENT.
CAPE VALUES APPROACHING 3000 TO 3500 J/KG ACROSS SOUTHERN
MISSOURI. SURFACE TEMPERATURES HAVE WARMED UP INTO THE LOWER 80S
WITH DEWPOINTS IN THE MIDDLE 60S. THE CAP IS WEAKENING AND WAS
AROUND -20 J/KG. 0-3KM STORM RELATIVE HELICITY VALUES ARE 250
M2/S2. PW VALUES AROUND 1.25 INCHES. STEEP LAPSE RATES ON THE
ORDER OF 8C/KM. WATER VAPOR IMAGERY IS SHOWING A WEAK MID LEVEL
WAVE OVER NORTHERN OKLAHOMA MOVING NORTHEAST AND WILL MOVE ACROSS
OUR WESTERN HALF OF THE AREA THIS AFTERNOON WHICH WILL HELP IN THE
DEVELOPMENT OF CONVECTION.

RADAR IS CURRENTLY SHOWING AN AREA OF STRONG CONVECTION ACROSS
WEST CENTRAL MISSOURI MOVING TOWARDS CENTRAL MISSOURI AT THIS
TIME. FOR THE NEXT COUPLE OF HOURS...EXPECT SCATTERED SHOWERS AND
THUNDERSTORMS TO CONTINUE TO DEVELOP MAINLY OVER SOUTHEAST KANSAS
AND FAR WESTERN MISSOURI THROUGH MID AFTERNOON. THERE WILL BE A
CONCERN FOR AN ISOLATED SUPERCELL POTENTIAL WHICH WILL BE ABLE TO
PRODUCE VERY LARGE HAIL...DAMAGING WIND GUSTS UP TO 70 MPH...AND
ISOLATED TORNADOES THROUGH THE REST OF THE AFTERNOON.

&&

.SYNOPSIS...
ISSUED AT 341 AM CDT WED APR 17 2013

A VERY ACTIVE 48 HOURS OR SO ARE ON TAP AS A SLOW MOVING STORM
SYSTEM TRAVERSES THE REGION. THE MAIN FORECAST CONCERNS CONTINUE TO
BE THE POTENTIAL FOR SEVERE STORMS AND FLOODING FROM THIS
AFTERNOON THROUGH THURSDAY. THE FLOODING THREAT HAS BEEN ADDRESSED
IN THE HYDRO SECTION BELOW. THERE ARE ALSO OTHER FORECAST CONCERNS
INCLUDING FOG EARLY THIS MORNING...TEMPERATURES...AND THEN THE
POTENTIAL FOR A FEW NIGHTS OF FROST/FREEZING TEMPERATURES LATER
THIS WEEK.

AS OF 3 AM...A WARM FRONT WAS ANALYZED FROM NORTHWESTERN ARKANSAS
INTO FAR SOUTH CENTRAL MISSOURI. THIS FRONT HAS JUST RECENTLY
STARTED TO RETURN NORTH WITH PRESSURE FALLS NOW NOTED ALONG AND
NORTH OF THE OZARK PLATEAU. ADDITIONALLY...THE KSGF 88D VAD WIND
PROFILE IS NOW INDICATED SOUTHERLY WINDS AT ALL LEVELS. THUS...THE
FRONTAL INVERSION OVERHEAD HAS THINNED OUT SINCE LATE TUESDAY
EVENING. MEANWHILE...SCATTERED SHOWERS AND THUNDERSTORMS HAVE
DEVELOPED FROM SOUTH CENTRAL KANSAS INTO FAR NORTHERN MISSOURI. THIS
ELEVATED CONVECTION HAS DEVELOPED IN AN AREA WHERE ISENTROPIC
UPGLIDE HAS ERODED A CAPPING INVERSION FOR PARCELS ROOTED AROUND OR
JUST BELOW THE 850 MB LEVEL.

&&

.SHORT TERM...(TODAY THROUGH FRIDAY)
ISSUED AT 341 AM CDT WED APR 17 2013

AS WE HEAD INTO THIS MORNING...PATCHY FOG WILL CONTINUE ACROSS
CENTRAL MISSOURI TO THE NORTH OF THAT WARM FRONT. MEANWHILE...THE
RAP AND OTHER SHORT RANGE MODELS REFOCUS A LOW LEVEL JET ACROSS
EASTERN OKLAHOMA AND VEER IT INTO SOUTHWESTERN MISSOURI.
TYPICALLY...A SETUP LIKE THIS WOULD YIELD SCATTERED TO NUMEROUS
SHOWERS AND THUNDERSTORMS ACROSS SOUTHEASTERN KANSAS AND WESTERN
MISSOURI. ONE THING THAT WILL BE INTERESTING TO SEE IS OUR 12 UTC
RAOB. INDICATIONS ARE THAT AN ELEVATED MIXED LAYER REMAINS
ENTRENCHED ACROSS THE REGION. EVEN ABOVE THIS LAYER...THERE IS AT
LEAST SOME QUESTION AS TO WHETHER OR NOT PARCELS WILL BE BUOYANT
GIVEN THE IMPINGING LOW LEVEL JET. AT THIS TIME...MY GUT FEELING
SAYS THAT WE WILL SEE ELEVATED CONVECTION DEVELOP ALONG AND WEST
OF THE HIGHWAY 65 CORRIDOR A BIT LATER THIS MORNING.

ONE SCENARIO WE WILL HAVE TO WATCH VERY CLOSELY TODAY IS THE
POTENTIAL FOR CONVECTION TO BECOME ROOTED IN THE BOUNDARY LAYER.
THERE ARE STILL SOME INDICATIONS BY SHORT RANGE MODELS THAT THIS
COULD OCCUR ACROSS THE MISSOURI OZARKS THIS AFTERNOON. AGAIN...THE
ASSUMED PRESENCE OF THAT ELEVATED MIXED LAYER WILL REALLY PLAY A
ROLE HERE. IF SURFACE BASED CONVECTION CAN DEVELOP...ENOUGH DEEP
LAYER SHEAR EXISTS FOR SUPERCELLS. ADDITIONALLY...THAT WARM FRONT
WILL BE RETURNING NORTH ACROSS THE OZARKS THROUGHOUT THE DAY. THAT
FRONT WILL BEEF UP LOW LEVEL SHEAR PROFILES AND PROMOTE THE
POTENTIAL FOR LOW LEVEL ROTATION. ANY NORTHEASTWARD MOVING LINE
SEGMENTS WOULD ALSO HAVE MESOVORTEX POTENTIAL GIVEN LOW LEVEL
SHEAR PROFILES. WE WILL THEREFORE ADVERTISE A LIMITED RISK FOR ALL
MODES OF SEVERE THIS AFTERNOON.

TEMPERATURE FORECASTS WILL BE JUST AS CHALLENGING AS THOSE OF
TUESDAY WITH THAT WARM FRONT RETURNING NORTH. AT THIS TIME...WE
FEEL THAT THE FRONT WILL MAKE IT INTO THE TRUMAN LAKE AND LAKE OF
THE OZARKS REGION BY LATE THIS AFTERNOON. THIS SHOULD RESULT IN
MOST AREAS WARMING AT LEAST INTO THE LOWER OR MIDDLE 70S.
LOCATIONS ACROSS SOUTH CENTRAL MISSOURI SHOULD APPROACH THE 80
DEGREE MARK.

PRECIPITATION COVERAGE MAY THEN ACTUALLY DIMINISH ACROSS MUCH OF THE
AREA THIS EVENING. THE ONE EXCEPTION WILL BE EXTREME SOUTHEASTERN
KANSAS AND WEST CENTRAL MISSOURI WHERE STRONG UPPER LEVEL DIFFLUENCE
SHOULD PROMOTE CONTINUED SHOWER AND THUNDERSTORM DEVELOPMENT.
CONVECTION IS THEN EXPECTED TO BECOME MORE FOCUSED LATE TONIGHT AS
HEIGHT FALLS OVERTAKE A COLD FRONT ACROSS EASTERN KANSAS. A LINE OF
STRONG TO SEVERE THUNDERSTORMS SHOULD SHARPEN UP AND PUSH INTO
WESTERN MISSOURI SOMETIME AFTER 2 AM. THIS LINE OF THUNDERSTORMS
WILL THEN MAKE SLOW PROGRESS TO THE EAST ACROSS THE MISSOURI OZARKS
DURING THE DAY ON THURSDAY...BEFORE EXITING SOUTH CENTRAL MISSOURI
EARLY THURSDAY EVENING. DAMAGING STRAIGHT LINE WINDS AND PERHAPS
SOME HAIL WILL BE POSSIBLE WITH THIS LINE OF STORMS. 0-3 KM BULK
SHEAR VECTORS ARE ALSO EXPECTED TO ALIGN FAVORABLY WITH THE FRONT TO
PROMOTE MESOVORTEX AND ATTENDANT ISOLATED TORNADO POTENTIAL.

HIGH TEMPERATURES ON THURSDAY WILL BE COMPLETELY DEPENDENT ON
FRONTAL TIMING. MANY LOCATIONS ACROSS THE CENTRAL AND EASTERN OZARKS
WILL SEE THEIR HIGH TEMPERATURES IN THE MORNING. BEHIND THAT
FRONT...A BRISK NORTHWEST WIND AND TEMPERATURES FALLING THROUGH THE
50S INTO THE 40S WILL BE A RUDE AWAKENING AFTER THE MILD
TEMPERATURES OF TODAY. CONTINUED COLD ADVECTION WILL THEN SET THE
STAGE FOR A POTENTIAL LIGHT FREEZE THURSDAY NIGHT. AT THIS TIME...IT
APPEARS THAT WINDS MAY BE A BIT TOO STRONG TO PROMOTE FROST
POTENTIAL. MUCH BELOW NORMAL TEMPERATURES WILL CONTINUE INTO FRIDAY
WITH HIGHS ONLY IN THE LOWER 50S. TEMPERATURES WILL AGAIN APPROACH
THE FREEZING MARK FRIDAY NIGHT ALTHOUGH MODELS DO INDICATE AN UPTICK
IN SOUTHWESTERLY SURFACE WINDS. IF THESE WINDS MATERIALIZE...IT
COULD KEEP MOST AREAS IN THE MIDDLE 30S VERSUS LOWER 30S. AT THIS
POINT...WE HAVE KEPT LOWS IN THE LOWER 30S.

.LONG TERM...(FRIDAY NIGHT THROUGH TUESDAY)
ISSUED AT 341 AM CDT WED APR 17 2013

MEDIUM RANGE MODELS THEN CONTINUE TO ADVERTISE WEAK SHORT WAVE
ENERGY MOVING ACROSS THE CENTRAL UNITED STATES LATER SUNDAY INTO
MONDAY. WE STILL BELIEVE THAT THIS WAVE WILL BE MOISTURE
STARVED...THUS WE HAVE KEPT POPS IN THE 20-30 PERCENT RANGE. MUCH
STRONGER ENERGY IS THEN PROGGED TO DIG THROUGH THE CENTRAL ROCKIES
AND EJECT OUT TOWARDS THE OZARKS AROUND MIDWEEK. THIS WILL BE OUR
NEXT GOOD SHOT AT WIDESPREAD RAINFALL. AS FOR TEMPERATURES...A
SLOW WARMING TREND IS EXPECTED FROM THIS WEEKEND INTO THE START OF
NEXT WORK WEEK.

&&

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON)
ISSUED AT 1158 AM CDT WED APR 17 2013

ACTIVE PERIOD FOR THIS TAF ISSUANCE. WARM FRONT HAS LIFTED NORTH
OF ALL 3 TAF SITES WHICH ARE NOW FIRMLY IN THE WARM SECTOR.
SHORTWAVE ENERGY SPREADING INTO THE AREA FROM THE SOUTHWEST COULD
HELP TO INITIATE CONVECTION WITHIN THE WARM SECTOR. MORE FAVORABLE
DEVELOPMENT WILL BE IN THE VICINITY OF THE FRONTAL BOUNDARY OVER
THE FAR NORTHWESTERN PORTION OF THE CWA AND PLAN ON KEEPING JLN
WITHIN A TEMPO GROUP FOR CONVECTION FOR SEVERAL HOURS THIS
AFTERNOON. THE MAIN SHOW FOR CONVECTION WILL LIKELY OCCUR AFTER
05Z AS THE UPPER LEVEL WAVE BEGINS TO KICK THE COLD FRONT
EASTWARD. LOW LEVEL WIND SHEAR WILL BE LIKELY FROM THIS EVENING
THROUGH THE OVERNIGHT HOURS. GENERALLY EXPECTING VFR CONDITIONS
UNTIL THE CONVECTION BEGINS AND THEN IFR/LIFR BOTH AHEAD OF AND
BEHIND THE FRONT.

&&

.HYDROLOGY...
ISSUED AT 341 AM CDT WED APR 17 2013

SCATTERED TO PERHAPS NUMEROUS SHOWERS AND THUNDERSTORMS ARE EXPECTED
FROM TODAY INTO THIS EVENING...WITH THE BEST COVERAGE EXPECTED TO
OCCUR ACROSS EXTREME SOUTHEASTERN KANSAS AND WEST CENTRAL MISSOURI.
LOCALLY HEAVY RAINFALL WILL BE POSSIBLE WITH THIS ACTIVITY. THE MAIN
THREAT FOR FLOODING IS THEN EXPECTED TO START LATE TONIGHT AND
CONTINUE INTO THURSDAY AS A SLOW MOVING LINE OF THUNDERSTORMS
ADVANCES EAST ACROSS THE MISSOURI OZARKS ALONG A COLD FRONT.
WIDESPREAD RAINFALL AMOUNTS OF ONE AND A HALF TO TWO AND A HALF
INCHES ARE EXPECTED FROM THIS MORNING THROUGH EARLY THURSDAY
EVENING. LOCALLY HIGHER AMOUNTS WILL BE LIKELY. ONE IMPORTANT NOTE
IS THAT RAINFALL RATES WITH THAT LINE OF STORMS WILL LIKELY APPROACH
1 AND 3 HOUR FLASH FLOOD GUIDANCE. THE CURRENT FLASH FLOOD WATCH
COVERS THIS WELL AND NO CHANGES ARE PLANNED AT THIS TIME. WE DID
CONSIDER ADDING A FEW COUNTIES TO THE SOUTH AND EAST OF THE CURRENT
WATCH...BUT HELD OFF TO GET A FEEL FOR FRONTAL SPEED AND BECAUSE THE
MAIN IMPACTS WILL OCCUR THURSDAY AFTERNOON. ONE FINAL NOTE IS THAT
WE WILL BE LOOKING AT RIVER CONTINGENCY FORECASTS CLOSELY TODAY TO
GAGE THE PROSPECTS FOR RIVER FLOODING.

1258 PM CDT WED APR 17 2013

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

.DAY ONE...THIS AFTERNOON AND TONIGHT.

WEATHER HAZARDS EXPECTED...

  ELEVATED TORNADO RISK.
  SIGNIFICANT HAIL RISK.
  ELEVATED THUNDERSTORM WIND DAMAGE RISK.
  ELEVATED FLOODING RISK.
  SIGNIFICANT LIGHTNING RISK.
  LIMITED NON THUNDERSTORM WIND RISK.

DISCUSSION...

  SCATTERED THUNDERSTORMS ARE EXPECTED TO DEVELOP BY EARLY
  AFTERNOON OVER THE WESTERN AREAS MAINLY WEST OF THE HIGHWAY 65
  CORRIDOR OF WESTERN MISSOURI AND SOUTHEAST KANSAS. HAIL UP TO
  THE SIZE OF HALF DOLLARS...DAMAGING WIND GUSTS UP TO
  60 MPH...FREQUENT LIGHTNING...AND BRIEF LOCALIZED HEAVY
  RAINFALL WILL BE POSSIBLE WITH SOME OF THESE STORMS.

  THERE IS AN ELEVATED THREAT FOR SUPERCELL THUNDERSTORM
  DEVELOPMENT FROM THIS AFTERNOON INTO EARLY THIS EVENING OVER
  THE WESTERN HALF OF THE AREA... PRIMARILY ALONG AND WEST OF THE
  HIGHWAY 65 CORRIDOR. IF THESE STORMS CAN DEVELOP...THERE WOULD
  BE A THREAT FOR HAIL TO THE SIZE OF GOLF BALLS...DAMAGING WIND
  GUSTS UP TO 70 MPH...AND A FEW TORNADOES POSSIBLE.

  NON THUNDERSTORM WIND GUSTS OVER 30 MPH ARE EXPECTED LATE
  THIS AFTERNOON AND ESPECIALLY TONIGHT AS A STRONG AREA OF LOW
  PRESSURE DEVELOPS ACROSS THE CENTRAL PLAINS.

  AS THAT AREA OF LOW PRESSURE MOVES INTO NORTHERN MISSOURI LATE
  TONIGHT...A LINE OF STRONG TO SEVERE THUNDERSTORMS WILL
  DEVELOP ALONG A SLOWLY ADVANCING COLD FRONT. THIS LINE OF
  STORMS IS EXPECTED TO MOVE INTO EXTREME SOUTHEASTERN KANSAS
  AND WEST CENTRAL MISSOURI AFTER 2 AM AND WILL APPROACH THE
  HIGHWAY 65 CORRIDOR AROUND SUNRISE. DAMAGING WIND GUSTS TO
  70 MPH...HAIL TO THE SIZE OF QUARTERS...FREQUENT LIGHTNING
  AND TORRENTIAL RAINFALL WILL BE POSSIBLE WITH THIS LINE OF
  STORMS. THERE WILL ALSO BE A THREAT FOR A ISOLATED
  TORNADOES EMBEDDED WITHIN THIS LINE.

  FLOODING OF CREEKS...STREAMS...AND LOW WATER CROSSINGS
  WILL ALL BE POSSIBLE...ESPECIALLY LATE TONIGHT ACROSS
  EXTREME SOUTHEASTERN KANSAS AND WEST CENTRAL MISSOURI.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY.

  THAT LINE OF STRONG TO SEVERE STORMS WILL SLOWLY MOVE EAST
  ACROSS THE CENTRAL AND EASTERN MISSOURI OZARKS ON THURSDAY.
  DAMAGING WIND GUSTS TO 70 MPH...HAIL TO THE SIZE OF
  QUARTERS...FREQUENT LIGHTNING AND TORRENTIAL RAINFALL WILL
  ALL REMAIN POSSIBLE WITH THIS LINE OF STORMS. THERE WILL ALSO
  BE A CONTINUED THREAT FOR ISOLATED TORNADOES EMBEDDED WITHIN
  THIS LINE.

  THE THREAT FOR FLOODING WILL ALSO PERSIST INTO THURSDAY WITH
  STORM TOTAL RAINFALL AMOUNTS FROM ONE AND A HALF TO OVER
  THREE INCHES EXPECTED. RESIDUAL FLOODING MAY THEN PERSIST
  INTO AT LEAST FRIDAY...INCLUDING THE POTENTIAL FOR MAIN STEM
  RIVER FLOODING.

  NON THUNDERSTORM WIND GUSTS OVER 30 MPH ARE EXPECTED ON
  THURSDAY AS A SHARPLY COLDER AIRMASS SPREADS OVER THE REGION
  BEHIND THAT COLD FRONT. FROST AND FREEZING TEMPERATURES WILL
  THEN BE POSSIBLE THURSDAY NIGHT AND AGAIN FRIDAY NIGHT.

  THUNDERSTORMS WILL AGAIN BE POSSIBLE AROUND THE MIDDLE OF
  NEXT WEEK AS A STORM SYSTEM TAKES SHAPE ACROSS THE CENTRAL
  UNITED STATES.

.SPOTTER INFORMATION STATEMENT...

  SPOTTER ACTIVATION MAY BE NEEDED IN THE NEXT THREE HOURS FOR
  AREAS ALONG AND WEST OF THE I-49 CORRIDOR ACROSS SOUTHEAST
  KANSAS AND EXTREME WESTERN MISSOURI. SPOTTER ACTIVATION MAY BE
  NEEDED LATE THIS AFTERNOON FOR AREAS WEST OF HIGHWAY 65 AND
  LATER TONIGHT FOR ALL AREAS OF THE MISSOURI OZARKS AND SOUTHWEST
  KANSAS. ACTIVATION MAY AGAIN BE NEEDED ON THURSDAY...ESPECIALLY
  ACROSS THE CENTRAL AND EASTERN MISSOURI OZARKS.
