What forecasters said that day

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

NWS Kansas City, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at Aug 4, 3:45 AM CDT, 2 hours 13 minutes earlier.

Area forecast discussion, Aug 4, 3:45 AM CDT, 2 hours 13 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
345 AM CDT TUE AUG 4 2009

.DISCUSSION...
BUSY MORNING WITH THE STORMS SO WILL KEEP THIS DISCUSSION ON THE
SHORT SIDE.

CURRENT CONVECTION IN NORTHWEST MISSOURI AND NORTHEAST KANSAS
COURTESY OF ISENTROPIC LIFT SHOWING UP BEST AROUND THE 316K LEVEL ON
THE NAM. STORMS IN NEBRASKA ASSOCIATED WITH A SHORT WAVE MOVING DOWN
IN THE NORTHWEST FLOW.  EXPECTING SOME FORM OF A MERGER BETWEEN
THESE TWO COMPLEXES TOWARD 12Z WITH THE SHORT WAVE THEN CONTINUING
TO MOVE THE CONVECTION TO THE EAST SOUTHEAST THIS MORNING. HOPING
THAT IN THE WAKE OF THIS CONVECTION WE WILL SEE SOME STABILIZATION
THIS AFTERNOON...SO WILL DOWNPLAY AFTERNOON POPS AND TARGET THEM FOR
AREAS WHERE MODELS ARE INDICATING THE CAPPING WILL BE THE WEAKEST.

SURFACE FRONT SHOULD PRESS SOUTH AFTER THE MORNING CONVECTION MOVES
THROUGH WITH A WEAK SURFACE WAVE ALSO EXPECTED ON THIS FRONT. THUS
TEMPERATURES TODAY WILL BE A BIT TRICKY...BUT WILL TREND TOWARD THE
SLIGHTLY COOLER NAM.

THEN FOR TONIGHT...WITH SURFACE BOUNDARY LIKELY TO BE JUST SOUTH OF
THE FORECAST AREA...MODELS ARE SHOWING THE BETTER ISENTROPIC LIFT TO
BE AIMED MORE INTO THE SOUTHERN PART OF THE FORECAST AREA. WILL KEEP
SOME CHANCE POPS FOR OVERNIGHT TO COVER THIS POSSIBILITY...BUT ALSO
KEEP SLIGHT CHANCE POPS GOING MUCH FURTHER NORTH DUE TO THE
UNCERTAINTY IN THIS FORECAST DUE TO THE POTENTIAL A WAVE IN THE
NORTHWEST FLOW APPROACHING FROM NEBRASKA TOWARD 12Z. WITH THE
POTENTIAL OF THIS SHORT WAVE MOVING ACROSS THE FORECAST AREA
WEDNESDAY MORNING...WILL RAISE POPS INTO THE CHANCE CATEGORY DURING
THE DAYTIME.

WEDNESDAY NIGHT COULD BE ANOTHER REPEAT OF STORMS WITH THE AREA ON
THE PERIPHERY OF THE UPPER RIDGE THAT WILL BE MOVING INTO THE TEXAS
PANHANDLE. WEAK RIDGE RUNNING WAVES WILL KEEP THE POTENTIAL OF
STORMS IN THE FORECAST AREA UNTIL THIS RIDGE BUILD STRONGER GOING
INTO FRIDAY. WITH THIS STRENGTHENING UPPER RIDGE...THE HEAT WILL
RETURN AS WELL. LONGER TERM PART OF THE CURRENT FORECAST HAS THIS
WELL DEPICTED SO NO MAJOR CHANGES MADE AFTER THURSDAY.

PC

&&

.AVIATION...
/1148 PM CDT MON AUG 3 2009/
FOR THE 06Z TAFS...A WEAK FRONT LOCATED NR KSTJ WL SAG SLOWLY SOUTH
THROUGH THE TERMINALS DURING THE MORNING HOURS. ALONG AND NORTH OF
THE BOUNDARY...A FEW THUNDERSTORMS MAY DEVELOP TONIGHT DUE TO
ISENTROPIC LIFT. AREAL COVERAGE IS EXPECTED TO BE LIMITED. THEREFORE
WILL ONLY MENTION VCTS. ANOTHER CONCERN IS THE LARGE AREA OF
CONVECTION IN NRN NEB. IT IS UNCLEAR WHETHER THE AREA OF STORMS WILL
SURVIVE BEFORE MAKING IT INTO THE TERMINALS AFT DAYBREAK.
OTHERWISE...THE FRONT WILL LIKELY NOT TRIGGER ANY THUNDERSTORMS IN
THE AFTN DUE TO THE INCREASING CAP.

1258 PM CDT MON AUG 3 2009

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHWEST...NORTH CENTRAL
AND WEST CENTRAL MISSOURI...AS WELL AS EXTREME EASTERN KANSAS.

.DAY ONE...THIS AFTERNOON AND TONIGHT

HOT AND HUMID CONDITIONS HAVE RETURNED TO THE LOWER MISSOURI RIVER
VALLEY THIS AFTERNOON. HIGH TEMPERATURES ARE EXPECTED TO TOP OUT IN
THE LOWER TO MIDDLE 90S ACROSS EASTERN KANSAS AND WESTERN MISSOURI.
HEAT INDEX READINGS WILL CLIMB TO NEAR 103 DEGREES BY MID AFTERNOON.

THERE WILL BE A CHANCE FOR AN ISOLATED THUNDERSTORM LATE THIS
AFTERNOON AS SEVERAL OUTFLOW BOUNDARIES REMAIN IN PLACE AFTER MORNING
THUNDERSTORMS. HOWEVER...AN INCREASING WARM LAYER OF AIR ALOFT MAY BE
STRONG ENOUGH TO SUPPRESS MOST ACTIVITY. SHOULD THUNDERSTORMS
DEVELOP...A HIGH DEGREE OF INSTABILITY WILL ALLOW STORMS TO QUICKLY BECOME
STRONG TO SEVERE WITH LARGE HAIL AND DAMAGING WINDS THE MAIN THREAT.
AN ISOLATED TORNADO CANNOT BE RULED OUT NEAR THE IOWA BORDER...BUT
THE THREAT REMAINS VERY LOW.

THE MORE LIKELY TIME FRAME FOR SEVERE STORMS WILL LATER THIS EVENING
AND THROUGH THE OVERNIGHT HOURS. BY THIS EVENING...A WEAK COLD FRONT
WILL BE NEARING THE IOWA MISSOURI BORDER. WITH THE SUPPORT OF A WEAK
UPPER LEVEL DISTURBANCE...STORMS ARE EXPECTED TO DEVELOP IN NORTH
CENTRAL AND NORTHEAST MISSOURI ALONG THE EDGE OF THE WARM LAYER
ALOFT. THESE STORMS MAY BUILD BACK WESTWARD ALONG THE SURFACE FRONT
TOWARDS NORTHWESTERN MISSOURI BY MIDNIGHT.  THE LEAST LIKELY AREA TO
SEE STORMS OVERNIGHT WILL BE IN WEST CENTRAL MISSOURI AND EAST
CENTRAL KANSAS TO THE SOUTH OF KANSAS CITY.

THE STORMS WILL BE CAPABLE OF PRODUCING DAMAGING WINDS AND LARGE
HAIL. HEAVY RAINFALL MAY ALSO OCCUR...AND IF STORMS REPEATEDLY
DEVELOP OVER A REGION...THIS MAY LEAD TO FLOODING ISSUES.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

THERE WILL BE A CONDITIONAL THREAT FOR THUNDERSTORMS ON
TUESDAY...WITH ACTIVITY HIGHLY DEPENDENT ON MONDAY NIGHTS
THUNDERSTORM ACTIVITY. THUNDERSTORMS ARE LIKELY TO BE ONGOING OVER
THE EASTERN PORTIONS OF THE OUTLOOK AREA TUESDAY MORNING...WITH A FEW
STRONG TO SEVERE STORMS STILL POSSIBLE. THE AFOREMENTIONED COLD FRONT
WILL SETTLE SOUTHWARD TO NEAR INTERSTATE 70 BY MID AFTERNOON...WITH
SUFFICIENT INSTABILITY DEVELOPING TO MAKE THUNDERSTORM REDEVELOPMENT
POSSIBLE. SEVERE WEATHER MAY BE POSSIBLE WITH ANY THUNDERSTORM THAT
DEVELOPS TUESDAY AFTERNOON.

MORE UNCERTAINTY FOR THUNDERSTORM ACTIVITY EXISTS ON WEDNESDAY AND
THURSDAY...WITH A POTENTIAL FOR SCATTERED THUNDERSTORMS BOTH DAYS. AT
THIS TIME...IT IS UNCERTAIN WHETHER SEVERE WEATHER WILL BE POSSIBLE.

WARMER TEMPERATURES WILL RETURN FOR FRIDAY AND LINGER THROUGH THE
WEEKEND. HIGH TEMPERATURES MAY SOAR WELL INTO THE 90S ONCE AGAIN.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED NORTH AND EAST OF A LINE FROM ST.
JOSEPH TO SEDALIA LATE THIS EVENING AND THROUGH THE OVERNIGHT HOURS.
SPOTTER ACTIVATION MAY BE NEEDED SOUTH OF INTERSTATE 70 ON TUESDAY.
