FORWARD-PROPAGATING MCS WILL CONTINUE TO DIVE SOUTH THROUGH

UPDATE...

IMPRESSIVE SQUALL LINE IS CURRENTLY TAKING SHAPE JUST NORTH OF THE
KANSAS CITY METRO...DIVING SOUTH/SOUTHEAST ON 310-315K GRADIENT.
LATEST SHORT-TERM GUIDANCE (NAM...RUC...HRRR...NORMAN WFO LOCALLY
RUN WRF) ALL SUGGEST THIS COMPLEX COULD CLIP PORTIONS OF SOUTHEAST
KS...GENERALLY EAST OF A LINE EXTENDING FROM COTTONWOOD FALLS TO
EUREKA TO INDEPENDENCE. ENVIRONMENT IS CHARACTERIZED BY STRONG
INSTABILITY...HIGH THETA-E AND STRONG DEEP LAYER SHEAR...AND
GIVEN STRONG SYSTEM RELATIVE INFLOW THINKING THIS COMPLEX SHOULD
CONTINUE TO DIVE SOUTHEAST...WITH AN ENHANCED THREAT FOR
WIDESPREAD DAMAGING WINDS.

ADK

PREV DISCUSSION... /ISSUED 646 PM CDT THU AUG 18 2011/

AVIATION...00Z TAFS KRSL/KSLN/KHUT/KICT/KCNU

A FEW HIT-AND-MISS THUNDERSTORMS WILL BE POSSIBLE ACROSS PORTIONS
OF CENTRAL AND SOUTH-CENTRAL KS THIS EVENING...POSSIBLY AFFECTING
ALL SITES EXCEPT KCNU. HAVE INSERTED "CB" CLOUD DESCRIPTOR THIS
EVENING FOR ALL SITES EXCEPT KCNU. MAIN THREATS WILL BE ISOLATED
STRONG/SEVERE WIND GUSTS DUE TO INVERTED-V SOUNDINGS. THINKING
THIS ACTIVITY SHOULD TEND TO WANE BEFORE MIDNIGHT. ATTENTION THEN
TURNS TO A LARGE THUNDERSTORM COMPLEX EXPECTED TO TRACK SOUTHEAST
ACROSS FAR EASTERN KS AND MISSOURI TONIGHT. THIS COMPLEX COULD
FLIRT WITH KCNU FROM ROUGHLY MIDNIGHT ON. A FAIRLY EXPANSIVE
OUTFLOW BOUNDARY IS THEN EXPECTED TO SURGE SOUTH ACROSS THE
FORECAST AREA LATER TONIGHT AND TOMORROW...LIKELY PROVIDING A
FOCUS FOR RENEWED AFTERNOON/EVENING THUNDERSTORM DEVELOPMENT
FRIDAY ACROSS THE AREA.

ADK

PREV DISCUSSION... /ISSUED 305 PM CDT THU AUG 18 2011/

DISCUSSION...
MAIN FORECAST UPDATES WILL FOCUS ON THUNDERSTORM CHANCES FOR THE
NEXT COUPLE DAYS ALONG WITH EXCESSIVE HEAT ON FRIDAY AFTERNOON.

TONIGHT
CURRENT CONDITIONS SHOW THUNDERSTORMS ERUPTING OVER NORTHEAST
NEBRASKA WITH A STRONG INSTABILITY AXIS EXTENDING FROM EASTERN
NEBRASKA SOUTHWARD INTO SOUTHEAST KANSAS. THE THUNDERSTORMS WILL
BECOME MORE NUMEROUS AND EVOLVE INTO A MCS AND RACE SOUTH/SOUTHEAST
TONIGHT ALONG THE INSTABILITY AXIS AND COULD CLIP SOUTHEAST KANSAS
TONIGHT. SEVERE WEATHER IS LIKELY WITH THIS COMPLEX OF STORMS. MEANWHILE
A FEW HIGH-BASED STORMS COULD POP OVER NORTH CENTRAL OKLAHOMA AND
SOUTH CENTRAL KANSAS FOR LATE THIS AFTERNOON/EVENING WHERE SOME
WEAK LOW LEVEL CONVERGENCE IS OCCURRING. PATCHY FOG COULD FORM OVER
CENTRAL KANSAS TOWARDS DAYBREAK...AS LIGHT MOIST EASTERLY FLOW
COMMENCES.

FRI-SUN
THE DANGEROUS HEAT INDICES WILL AFFECT MUCH OF THE REGION AGAIN
FOR FRIDAY AFTERNOON...AND WILL KEEP THE HEAT ADVISORY IN PLACE.
MEANWHILE LOCATION OF THE OUTFLOW BOUNDARY FROM THURSDAY NIGHT MCS
WILL PLAY A ROLE IN FAVORED AREAS FOR THUNDERSTORM REDEVELOPMENT
BY LATE FRIDAY AFTERNOON. EXPECTING DECENT MOIST UPSLOPE FLOW TO
SPARK OFF THE NEXT ROUND OF STORMS IN THE HIGH PLAINS REGION
FRIDAY AFTERNOON...WITH ANOTHER AREA OF STORMS POSSIBLE ALONG THE
OUTFLOW BOUNDARY. THE ACTIVITY COMING OFF THE HIGH PLAINS WILL
CONGEAL AND FORM ANOTHER MCS WHICH LOOKS TO IMPACT CENTRAL KANSAS
FRIDAY NIGHT. SEVERE WEATHER WILL ONCE AGAIN BE A POSSIBILITY
GIVEN EXPECTED SHEAR/INSTABILITY COMBINATION. THIS FRIDAY NIGHT
ACTIVITY WILL MURKY THE FORECAST WATERS FOR SATURDAY WITH
UNCERTAINTY ON LOCATION OF MESO-SCALE BOUNDARIES...THEREFORE WE WILL
GO WITH SMALL CHANCE POPS FOR SATURDAY. WE WILL KEEP SUNDAY DRY
AT THIS JUNCTURE FOR KANSAS WITH THE BOUNDARY LIKELY REMAINING
SOUTH OF THE AREA.

EXTENDED: MON-THU
MODELS IN GOOD AGREEMENT THAT THE UPPER RIDGE WILL AMPLIFY OVER THE
ROCKIES...WITH NORTHWEST FLOW ALOFT PERSISTING ACROSS THE CENTRAL
PLAINS THIS PERIOD. A COUPLE UPPER WAVES WILL TRAVEL DOWN THE
NORTHWEST FLOW REGIME WITH THE MOST ROBUST WAVE PREDICTED BY THE
MODELS MOVING FROM THE NORTHERN PLAINS INTO THE GREAT LAKES DURING
THE TUESDAY/TUESDAY NIGHT TIME FRAME. SHOWERS AND THUNDERSTORMS ARE
LIKELY AHEAD OF THESE WAVES...BUT THE HIGHER CHANCES OF
PRECIPITATION LOOK TO BE EAST OF KANSAS WHERE MOISTURE TRANSPORT IS
FOCUSED. NEAR NORMAL TEMPERATURES AND DRY WEATHER SHOULD PREVAIL FOR
WED/THU AS SURFACE HIGH PRESSURE BUILDS SOUTHWARD INTO THE CENTRAL
PLAINS.

JAKUB

AVIATION...18Z TAFS KRSL/KSLN/KHUT/KICT/KCNU
TWO TAF CONCERNS...FIRST WILL BE A CHANCE OF ISOLD/WIDELY SCT
TSRA FROM EAST OF KSLN TO KCNU EARLY THIS EVENING IN CLOSE
PROXIMITY TO A WARM FRONT LOCATED BASICALLY FROM KMHK TO KCNU.
WILL PLACE A VCTS IN THE KSLN/KCNU TAFS FOR THIS INITIAL CHANCE.

NEXT CONCERN WILL BE A CHANCE OF MORE NUMEROUS STORMS OVER SE NEB
AND NE KS FORMING INTO A COMPLEX OF TSRA AND SURGING SOUTH TOWARDS
SE KS VERY LATE THIS EVENING BETWEEN 03-07Z/FRI. THIS SURGING
COMPLEX WILL AFFECT THE KCNU TAF SO WILL GO WITH A WIND SHIFT TO THE
NORTH AND VCTS FOR THIS CHANCE. NOT COMPLETELY CONFIDENT TO ADD A
TEMPO TSRA GROUP FOR GUSTY WINDS JUST YET...BUT COULD SEE A CHANCE
OF VARIABLE GUSTY WINDS OF 25 TO 45 KTS WHEN IT ARRIVES. WILL ALSO
TRY AND TIME A POSSIBLE OUTFLOW BOUNDARY FROM THIS COMPLEX INTO
KICT/KSLN/KHUT BY AROUND 06Z WITH A WIND SHIFT TO THE EAST.
