What forecasters said that day

The local office's own words before this flash flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Wichita, KS wrote its last area forecast discussion before this flash flood warning went out at Aug 29, 2:37 AM CDT, 2 hours 36 minutes earlier.

Area forecast discussion, Aug 29, 2:37 AM CDT, 2 hours 36 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WICHITA KS
237 AM CDT FRI AUG 29 2008

.DISCUSSION...
MAIN FORECAST CONCERNS WILL DEAL WITH LINGERING PRECIPITATION FOR
TODAY...FOLLOWED BY CHANCES AGAIN ON SATURDAY AND NEXT WEEK.

TDY-TONIGHT
LINGERING SHOWERS AND THUNDERSTORMS WILL AFFECT SOUTHERN KANSAS THIS
MORNING AS WEAK ISENTROPIC LIFT PERSISTS. MEANWHILE...THE FRONTAL
BOUNDARY WILL CONTINUE TO PUSH SOUTHWARD ACROSS KANSAS AND STALL OUT
ACROSS OKLAHOMA TODAY. THUNDERSTORMS SHOULD REDEVELOP ALONG THE
FRONT LATER THIS AFTERNOON BUT SHOULD BE MAINLY SOUTH OF THE BORDER.

SAT-SUN
COOLER MID-LEVEL TEMPS AND STRONG DAYTIME HEATING ON SATURDAY SHOULD
LEAD TO AN UNCAPPED ENVIRONMENT ACROSS SOUTHERN KANSAS...AND A WEAK
UPPER LEVEL WAVE COULD BE ENOUGH TO DISTURB THE ENVIRONMENT FOR
WIDELY SCATTERED ACTIVITY. TEMPS SHOULD WARM UP A BIT ON SUNDAY AS
THE WARM FRONT KEEPS ON MOVING FURTHER NORTH WITH DRY WEATHER
EXPECTED.

EXTENDED: MON-THU
WARM AND HUMID CONDITIONS LOOK TO PREVAIL FOR MONDAY AND TUESDAY
BEFORE NEXT FRONTAL BOUNDARY AND COOLER WEATHER AFFECTS KANSAS BY
MID-WEEK.

WE HAVE SLOWED DOWN THE TIMING OF THE FRONTAL BOUNDARY FOR
TUESDAY...AS HURRICANE GUSTAV COULD HAVE A SLOWING DOWN EFFECT FOR
WEATHER SYSTEMS ACROSS THE CENTRAL PLAINS. PRECIPITATION CHANCES
LOOK DECENT FOR TUESDAY NIGHT INTO WEDNESDAY AS A COLD FRONT MOVES
INTO JUICY GULF MOISTURE RESIDING OVER THE AREA.

JAKUB

.AVIATION...06Z TAFS: KRSL/KSLN/KHUT/KICT/KCNU
COLD FRONTAL BOUNDARY CONTINUES TO MAKE SLOW PROGRESS ACROSS
SOUTHERN  KS AT THIS TIME...WITH THE SLOWEST PROGRESS BEING MADE
OVER SOUTHEASTERN KS. SOME ELEVATED CONVECTION CONTINUES TO DEVELOP
JUST TO THE NORTH OF THIS BOUNDARY GENERALLY TO THE NORTHWEST OF
KCNU.  EXPECT THIS CONVECTION TO SLOWLY DRIFT SOUTHEAST AS THE
OVERNIGHT PROGRESSES....SO WILL KEEP A VCTS GROUP IN KCNU TAF FOR
NOW. THE REST OF THE TAF SITES WILL SEE A RETURN TO VFR CONDITIONS
OVERNIGHT INTO FRI AS NORTHERLY WINDS SETTLE INTO THE AREA AFTER THE
FRONTAL PASSAGE.

FRONTAL BOUNDARY COULD STILL LINGER OVER SOUTHEAST KS FOR THE
AFTERNOON ON FRI. NOT TOO SURE WE WILL SEE ANY CONVECTION IN AND
NEAR THE KCNU TAF SITE...SO WILL ONLY GO WITH A CB CLOUD DECK FOR
NOW.
