AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
643 PM CDT TUE MAR 20 2012

...MESOSCALE CONVECTIVE DISCUSSION...

.UPDATE...

LOW END SEVERE CHANCES CONTINUE ACROSS THE EASTERN PORTIONS OF THE
CWA THIS EVENING. SHARP AIRMASS BOUNDARY HAS BEEN ANALYZED ACROSS
THE CENTRAL TO EASTERN OZARKS...GENERALLY IN A NORTH/SOUTH LINE
FROM GAINSVILLE TO FT. WOOD TO OSAGE BEACH. AIRMASS REMAINS A BIT
UNSTABLE EAST OF THIS BOUNDARY...WITH OBJECTIVE ANALYSIS
INDICATING ONLY A COUPLE HUNDRED JOULES/KG OF CAPE AVAILABLE OVER
THIS AREA. SHEAR IS CERTAINLY NOT A PROBLEM...WITH VERY STRONG
EFFECTIVE BULKS AND LOW LEVEL SRH IN PLACE OVER THE AREA.

WITH SUCH A STRONGLY SHEARED ENVIRONMENT...WILL NEED TO KEEP A
CLOSE EYE ON POTENTIAL FOR ISOLATED MESOVORTS AND/OR MINI/LOW-TOPPED
SUPERCELL STRUCTURES THROUGH THE FIRST PART OF THE EVENING. HAVE
OBSERVED WHAT APPEARS TO BE SOME WAVE STRUCTURES MOVING NORTH AT A
FASTER PACE THAN THE OVERALL CONVECTION...WHICH SEEM TO RESULT IN
CONVECTION PERKING UP A BIT AS THEY INTERACT WITH THESE FEATURES.
THIS WILL ALSO NEED TO BE WATCHED THROUGH THE EVENING. MAIN
THREATS THIS EVENING WOULD BE BRIEF SPIN-UP TORNADOES AS WELL AS A
FEW STRONG WIND GUSTS AS 50 KT ENVIRONMENTAL 850 MB WINDS
OCCASIONALLY MAKE IT DOWN TO THE SURFACE.

OVERALL THREAT DOES REMAIN LIMITED...AND PER PHONE COORDINATION
WITH SPC...WILL BE HOLDING OFF ON ANY SORT OF WEATHER WATCH
ISSUANCE UNLESS ADDITIONAL SEVERE WEATHER REPORTS ARE RECEIVED.

.DISCUSSION...

SHORT TERM (TONIGHT THROUGH THURSDAY)...

THE STALLED OUT UPPER LEVEL LOW IS CURRENTLY OVER WESTERN TEXAS
THIS AFTERNOON. SPOKES OF ENERGY CONTINUE TO PIN WHEEL AROUND THIS
SYSTEM BRINGING ROUNDS OF SHOWERS WITH ISOLATED STORMS. SO FAR
WITH THIS EVENT...THERE HAS BEEN A GENERAL 3 TO 5 INCHES OF
RAINFALL ALONG AND WEST OF HIGHWAY 71 WITH ONE TO TWO INCHES ALONG
AND WEST OF HIGHWAY 65. AREAL FLOODING AND RIVER FLOODING CONTINUES OVER
PORTIONS OF SOUTHEAST KANSAS AND EXTREME WESTERN MISSOURI.
EXPECTING AN ADDITIONAL ONE TO THREE INCHES OF RAINFALL ACROSS THE
AREA WITH THE HIGHER AMOUNTS BETWEEN HIGHWAY 71 AND HIGHWAY 5
THROUGH TOMORROW NIGHT.

AS FOR THIS EVENING AND TONIGHT...WHILE THE SEVERE THREAT IS NOT
COMPLETELY ZERO...THE CHANCES ARE EXTREMELY LOW FOR A SEVERE WIND
GUST OR SPIN UP TORNADO. AGAIN THE LIMITING FACTOR CONTINUES TO BE
THE INSTABILITY TO DEVELOP DEEP CONVECTION. ONE BAND OF CONVECTION
WILL CONTINUE TO MOVE ACROSS THE EASTERN OZARKS THIS EVENING WITH
ANOTHER BAND OF CONVECTION NOW DEVELOPING DOWN IN WESTERN ARKANSAS
WILL ROTATE UP ACROSS SOUTHEAST KANSAS AND SOUTHWEST MISSOURI
LATER THIS EVENING. ANY ADDITIONAL RAINFALL ON SATURATED GROUNDS
WILL AGGRAVATE AREA STREAMS AND RIVERS. THE CENTRAL AND EASTERN
OZARKS HAVEN'T SEEN THAT MUCH RAINFALL YET WITH THIS SYSTEM AND
WILL TAKE A WHILE FOR THE RAIN TO SATURATE THE GROUND IN THESE
AREAS. BUT IF THERE IS ANY TRAINING OF HEAVIER SHOWERS AND
STORMS...THERE COULD BE SOME ADDITIONAL FLOOD WARNINGS ISSUED
LATER TONIGHT. LOOKING AT MODEL DATA...SUGGESTION ANOTHER JET
STREAK COMING AROUND THE BASE OF THE UPPER LEVEL LOW UP THROUGH
THE OZARKS TONIGHT ALONG WITH A DECENT LOW LEVEL JET. THIS COULD
LEAD TO ANOTHER ENHANCEMENT OF RAINFALL LATER THIS EVENING FOR
SOUTHWEST MISSOURI.

LOOKING INTO TOMORROW...THERE APPEARS TO BE A SLIGHT BREAK IN THE
RAIN MID TO LATE MORNING WITH ANOTHER ROUND OF SHOWERS AND MAYBE
AN ISOLATED THUNDER DEVELOPING BY LATE AFTERNOON INTO WEDNESDAY
EVENING. THIS APPEARS TO BE THE LAST OF THE HEAVIER RAINFALL WITH
THIS LOW AS THE LOW WILL START MOVING TO THE NORTHEAST AND
SHIFTING THE MAIN CONVEYOR BELT OF MOISTURE AND CONVECTION OUT OF
THE AREA.

GRIFFIN

LONG TERM (FRIDAY THROUGH TUESDAY)...

THE UPPER LEVEL LOW WILL CONTINUE TO MOVE EASTWARD ON
FRIDAY...KEEPING SCATTERED SHOWERS AND THUNDERSTORMS OVER THE AREA
THROUGH THE DAY...DIMINISHING IN THE EVENING HOURS.  THE PERSISTENT
CLOUD COVER ON FRIDAY WILL KEEP TEMPERATURES COOL...WITH HIGHS IN
THE LOWER 60S EXPECTED.  TEMPERATURES WILL WARM INTO THE WEEKEND AS
A RIDGE BUILDS INTO THE AREA AND SKIES BEGIN TO CLEAR.  HIGH TEMPERATURES
WILL RISE INTO THE UPPER 60S BY SATURDAY WITH MID 70S EXPECTED BY
SUNDAY.  THESE WARMER TEMPERATURES WILL PERSIST INTO THE BEGINNING
OF THE WORK WEEK.  THERE IS THE POTENTIAL FOR MORE RAINFALL ON
TUESDAY AS ANOTHER STORM SYSTEM PASSES JUST NORTH OF THE AREA.
SIGNIFICANT MODEL DIFFERENCES EXIST AT THIS TIME...SO THERE IS NOT
MUCH CONFIDENCE FOR THE TUESDAY PRECIPITATION FORECAST AT THIS TIME.

.AVIATION...

FOR THE 18Z TAFS...EXPECTING CEILINGS AND VIS TO DROP TO MVFR BY
LATE AFTERNOON AND THIS EVENING FOR ALL TERMINALS AS SHOWERS AND
ISOLATED TS MOVES ACROSS THE OZARKS. WINDS WILL REMAIN GUSTY THIS
AFTERNOON OUT OF THE SOUTH-SOUTHEAST EXCEPT FOR JLN WITH WINDS OUT
OF THE EASTERLY DIRECTION. BBG MAY DROP DOWN TO IFR CELINGS LATER
TONIGHT. SHOWERS WILL BE LIKELY TONIGHT THROUGH TOMORROW MORNING.
