.DISCUSSION...
/319 AM CDT SAT JUL 24 2010/
MAIN CONCERN FOR THIS FORECAST DEALS WITH CONVECTIVE CHANCES TODAY
AND PARTICULARLY THIS AFTERNOON AS A COLD FRONT WILL WORK SOUTHWARD
THROUGH THE FORECAST AREA.
SYNOPSIS:
A STRONG UPPER LEVEL SYSTEM MOVING ACROSS THE NORTHERN PLAINS WAS
PROVING A SOLID PUSH TO THE FRONTAL BOUNDARY DRAPED ACROSS NEBRASKA
AND IOWA AND AIDING CONVECTION ACROSS THE UPPER MIDWEST TRAILING
SOUTHWESTWARD INTO IOWA. VERY WARM TEMPERATURES ALOFT...
CHARACTERIZED BY 700MB TEMPS OF 12 TO 14 C...WERE INHIBITING
DEVELOPMENT FURTHER SOUTH AND SOUTHWEST. HOWEVER ISENTROPIC ASCENT
AROUND 315K SEEMED TO BE TRIGGERING SHOWERS/STORMS AHEAD OF THE
FRONT. THE 00Z/24 TOP AND SGF SOUNDINGS SHOW DEEP MOISTURE ACROSS
THE REGION AS DEWPOINTS HAVE REMAINED IN THE MIDDLE 70S DESPITE
CONTINUED MIXING/GUSTY WINDS DURING THE OVERNIGHT HOURS.
TODAY:
A COLD FRONT WILL PUSH INTO THE FORECAST AREA THIS MORNING AND BE
SITUATED ROUGHLY ALONG AND SOUTH OF THE METRO BY THE AFTERNOON. WITH
AFTERNOON TEMPERATURES EXPECTED TO CLIMB INTO THE LOW TO MID 90S
AHEAD OF THE FRONT AND COPIOUS LOW LEVEL MOISTURE...INSTABILITY IS
EXPECTED TO BE EXTREME...LIKELY 3000 TO 4000 J/KG. WITH A LACK OF
SHEAR TO SUPPORT ANY KIND OF STORM ORGANIZATION THE PRIMARY
CONVECTIVE MODE WILL BE PULSEY MULTICELL CLUSTERS. WITH SUCH ABUNDANT
MOISTURE AND THE PULSEY NATURE TO THE STORMS EXPECTED THE PRIMARY
THREAT SHOULD BE FROM DAMAGING DOWNBURST WINDS. ALSO...PRECIPITABLE
WATER VALUES APPROACHING 2.5 INCHES WILL SUPPORT THE POTENTIAL FOR
LOCALIZED BUT EXTREMELY HEAVY RAINFALL WITH ANY STORM LEADING TO A
LOCAL FLASH FLOOD THREAT. WILL KEEP THE HEAT HEADLINES AS IS. WITH
FRONTAL TIMING VERY SIMILAR TO THE PREVIOUS FORECAST FEW CHANGES WERE
MADE TO TEMPS AND DEWPOINTS. THIS RESULTS IN HEAT INDEX VALUES
BETWEEN 103 AND 106 IN THE ADVISORY AREA.
TONIGHT - SUNDAY:
THE FRONT IS EXPECTED TO STALL ACROSS SOUTHERN MISSOURI AND KANSAS
WITH PRECIPITATION CHANCES CONTINUING FOR AREAS GENERALLY SOUTH OF
THE MISSOURI RIVER FOR SUNDAY. WITH THE AREA BEING ON THE COOL SIDE
OF THE FRONT AND THE POTENTIAL FOR CLOUD COVER AND PRECIPITATION
HIGHS WILL BE COOLER...LIKELY IN THE MIDDLE 80S.
EARLY NEXT WEEK:
WATER VAPOR CONTINUES TO SHOW AN UPPER LEVEL SYSTEM RAPIDLY MOVING
INTO THE NORTHWESTERN GULF OF MEXICO. THE GFS SEEMED TO HAVE THE
BEST HANDLE ON THIS CLOSED LOW AND TRACKS IT INTO WEST TEXAS BY
TUESDAY AFTERNOON. WITH SUCH WEAK FLOW ANTICIPATED OVER THE AREA
CONFIDENCE ON WHERE THIS LOW TRACKS REMAINS QUITE LOW. WILL CONTINUE
LOW END POPS THROUGH TUESDAY AS IT APPEARS THE STALLED BOUNDARY WILL
BEGIN TO LIFT NORTHWARD AS A WARM FRONT AND THE POTENTIAL IMPACTS OF
THE ABOVE MENTIONED LOW.
CDB
&&
.AVIATION...
FOR THE 18Z TAFS...WEAK COLD FRONT CONTINUES TO SLOWLY MOVE SOUTH
ACROSS THE AREA THIS AFTERNOON. PRE-FRONTAL CONVECTION THIS MORNING
IS SHIFTING NORTHEAST...LEAVING MAINLY POST-FRONTAL CONVECTION OVER
NORTHWEST MISSOURI-NORTHEAST KANSAS. HOWEVER AS THE FRONT CONTINUES
SOUTH THIS AFTERNOON...INCREASINGLY UNSTABLE AIRMASS SHOULD BE
FORCED BY THE FRONT...CAUSING AT LEAST SCATTERED STORMS ALONG IT.
THIS MAY HAPPEN OVER THE KC TAF SITES THIS AFTERNOON. ONCE THE COLD
FRONT CLEARS THE TERMINALS THIS EVENING...THE THREAT OF CONVECTION
WILL END. MAY SEE MVFR CIGS CONTINUE UNTIL ROUGHLY MID EVENING.

GIVEN THE POTENTIAL FOR EXTREME INSTABILITY ALONG AND AHEAD OF THE FRONT...THERE IS A CHANCE THAT A FEW STORMS COULD BE STRONG TO SEVERE DURING THE AFTERNOON AND EARLY EVENING HOURS. THE PRIMARY HAZARDS FROM THESE STORMS WILL BE FROM DAMAGING WINDS AND LOCALLY HEAVY RAIN WHICH MAY LEAD TO LOCALIZED FLASH FLOODING. SEVERE THUNDERSTORMS ARE MOST LIKELY ALONG AND SOUTH OF A LINE FROM KANSAS CITY TO KIRKSVILLE. WHILE SOME UNCERTAINTY EXISTS DUE TO CLOUD COVER...TEMPERATURES ARE EXPECTED TO ONCE AGAIN CLIMB INTO THE LOWER TO MIDDLE 90S THIS AFTERNOON ACROSS PARTS OF THE OUTLOOK AREA. THIS MAY RESULT IN CONTINUED DANGEROUS HEAT CONDITIONS...MAINLY ALONG AND SOUTH OF A LINE FROM PAOLA KANSAS TO MOBERLY MISSOURI. .DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY THERE IS A SMALL CHANCE FOR THUNDERSTORMS PERSISTING THROUGH THE BEGINNING OF NEXT WEEK...HOWEVER THE SEVERE WEATHER POTENTIAL REMAINS LOW. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NEEDED THIS AFTERNOON ACROSS AREAS ALONG AND SOUTH OF A KANSAS CITY TO KIRKSVILLE LINE. CUTTER
