AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
644 PM CDT SAT APR 29 2006

.DISCUSSION...
INVERTED SURFACE TROUGH EXTENDS NORTH FROM A LOW CENTER OVER EASTERN
OK ATTM. THE FORECAST REGION...FOR THE MOST PART...HAS BEEN COVERED
WITH LOW CLOUDS. SMALL BREAKS THAT HAD DEVELOPED UNDER THE MID/UPPER
LEVEL DRY SLOT ROTATING NORTHEAST INTO THE WESTERN PORTION OF THE
FORECAST AREA HAS QUICKLY FILLED IN WITH SHALLOW CONVECTION OVER
NORTHWEST AR AND SOUTHERN/SOUTHWEST MO.

THE LOW CENTER OVER OK IS EXPECTED TO LIFT RAPIDLY NORTH THROUGH MO
LATE THIS AFTERNOON AND THIS EVENING. MID LEVEL LAPSE RATE SHOULD
ALSO CONTINUE TO INCREASE WITH THE APPROACH OF AN UPPER LEVEL TROUGH
OVER KS/OK. THE OBVIOUS LIMITATION TO STRONG/SEVERE CONVECTIVE
REDEVELOPMENT WILL BE AVAILABLE SURFACE (OR NEAR SURFACE) BASED
INSTABILITY...WHICH LOOKS TO REMAIN LIMITED ATTM...HOWEVER THERE IS
PLENTY OF DEEP LAYER SHEAR AVAILABLE (500MB WIND OF 65KTS AT CONWAY
PROFILER ATTM). LINE OF STORMS IS DEVELOPING IN SOUTHEAST OK IN AXIS
OF STRONGER INSTABILITY ALONG WITH WEAKER CONVECTION DEVELOPING IN A
WEAK AXIS OF LOW LEVEL MOISTURE CONVERGENCE FROM NORTHEAST OK INTO
SOUTHWEST MO. ALSO SEEING ISOLATED STORMS IN NORTHWEST AR DEVELOPING
DECENT UPDRAFTS DESPITE ONLY 500 J/KG MU CAPE...HOWEVER THESE
QUICKLY WEAKENED AS THEY MOVED NORTH. LOOKS LIKE BEST CHANCES FOR
STRONGER STORMS WILL BE WITH THE INSTABILITY AXIS ASSOCIATED WITH
THE CLEARING NOW MOVING INTO EASTERN OK AS IT ROTATES NORTHEAST
TOWARD SOUTHWEST MO LATE THIS AFTERNOON AND EARLY THIS EVENING.

THE SURFACE WIND IS VERY BACKED OVER ARKANSAS...NORTHEAST OF THE
SURFACE LOW. RUC INDICATES 0-1KM HELICITY OF 800 M2/S2 OVER CENTRAL
AR...AND EXPECT THAT ENVIRONMENT TO MOVE NORTHWARD INTO SOUTHERN MO
WITH THE SURFACE LOW LATER THIS AFTERNOON. WITH VERY FAVORABLE WIND
PROFILES...WE WILL ONLY NEED MODEST INSTABILITY TO GET STRONG/SEVERE
CONVECTION GOING...SO HAVE HIT THE WORDING A LITTLE HARDER IN THE
HWO...MAINLY FOR SOUTHERN MO...BUT LOSING CONFIDENCE IN SEVERE
CHANCES AS THE AFTERNOON WEARS ON GIVEN VERY LIMITED INSTABILITY.

WE HAVE ONGOING RIVER AND GENERALLY MINOR FLOODING ONGOING IN
SCATTERED AREAS...AND WE WILL NEED TO CONTINUE TO MONITOR FOR HEAVY
RAIN AND FLOODING...ESPECIALLY OVER THE WESTERN CWA WHERE...IN
GENERAL...THE HEAVIEST RAIN OCCURRED YESTERDAY. THE WAY THIS IS
EVOLVING...THIS LOOKS TO BE MORE OF HYDROLOGIC EVENT VERSUS SEVERE.
WE ARE GETTING SOME MUCH NEEDED RAINFALL OVER THE REGION.

UPPER LOW WILL MEANDER NORTH OF THE REGION SUNDAY INTO MONDAY...AND
HAVE MAINTAINED RAIN CHANCES FOR THAT TIME PERIOD AS SHORTWAVES
ROTATE AROUND THE MAIN UPPER SYSTEM. THE UPPER LOW SHOULD WEAKEN AND
BE KICKED EAST AS ANOTHER SYSTEM MOVES INTO THE PACIFIC NORTHWEST.
THIS NEXT UPPER TROUGH AND ASSOCIATED SURFACE COLD FRONT IS STILL
EXPECTED TO AFFECT THE FORECAST AREA LATE WEDNESDAY INTO THURSDAY.
CONSIDERABLE DIFFERENCE IN TIMING EXISTS WITH MEDIUM RANGE
MODELS...WITH THE ECMWF BEING MUCH FASTER THAN THE GFS. AS A
HEDGE...HAVE INTRODUCED SMALL POPS INTO WESTERN PORTIONS OF THE
FORECAST AREA LATE IN THE DAY WEDNESDAY. THE TIMING WILL NO DOUBT
NEED TO BE ADJUSTED. DSA

.AVIATION...
FOR THE 00Z TAFS...SURFACE LOW WAS LIFTING NORTH ALONG THE KANSAS
MISSOURI BORDER THIS EVENING AND WAS NEAR JLN AS OF 2340Z.  RAIN HAD
BRIEFLY ENDED AS OF TAF ISSUANCE AT JLN WITH MORE CONVECTIVE BAND
MOVING THROUGH SGF TERMINAL LOCATION.  SOME WRAP AROUND RAIN WILL
STILL AFFECT JLN AND POSSIBLY SGF BUT IT APPEARS MAIN BAND OF
PRECIPITATION SHOULD END SHORTLY FOR SGF/JLN.  CEILINGS OVERNIGHT
WILL LIKELY REMAIN AROUND 1000 TO 2000 FEET WITH VISIBILITIES OF 2
TO 5 MILES AND FOG.
