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 Springfield, MO wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 18, 3:31 AM CDT, 2 hours 28 minutes earlier.

Area forecast discussion, Jun 18, 3:31 AM CDT, 2 hours 28 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
331 AM CDT SAT JUN 18 2011

.DISCUSSION...

FOR THIS FORECAST...MAIN CONCERNS REVOLVE AROUND ONGOING
CONVECTION ACROSS CENTRAL MISSOURI ASSOCIATED WITH AN MCV...THE
POTENTIAL FOR A SIMILAR SYSTEM TONIGHT AND CHANCES FOR
THUNDERSTORMS AND POTENTIAL SEVERE WEATHER FOR THE MIDDLE OF THE
WEEK.

THUNDERSTORMS NOW ONGOING ACROSS CENTRAL PORTIONS OF MISSOURI WILL
MOVE LIKELY BEGIN TO DEVELOP TO THE SOUTHEAST WHERE 700MB
TEMPERATURES FALL TO BELOW 14 DEGREES. FOR MUCH OF THE NIGHT THIS
CONVECTION HAS BEEN ALONG AND NORTH OF THIS LINE. WHILE THIS MAY
NOT BE THE PRIMARY FACTOR IN LIMITING STORM DEVELOPMENT TO THE
SOUTH OTHER FACTORS SUCH AS THE MCV...MUCAPE VALUES ABOVE
2000J/KG AND A 45KT LOW LEVEL JET NOSING INTO THE AREA WILL AT
LEAST KEEP THE STORMS ON AN EASTWARD TRACK WHICH WOULD EFFECT
CENTRAL MISSOURI. THIS MCS SHOULD DISSIPATE LATE THIS MORNING.
THERE IS A CHANCE THAT A SIMILAR MCS WILL DEVELOP ACROSS EASTERN
KANSAS AND IMPACT THE MISSOURI OZARKS AGAIN THIS EVENING AND
TONIGHT. THE PRIMARY THREATS WOULD BE GUSTY STRAIGHT LINE WINDS
AND SOME HAIL. A BRIEF SPIN UP ALSO CAN NOT BE RULED OUT.

THE UPPER LEVEL RIDGE AND 700MB THERMAL RIDGE IS EXPECTED TO
WEAKEN TODAY AS A WEAK UPPER LEVEL SHORT WAVE MOVES ACROSS THE TOP
OF THE RIDGE AND SUPPRESSES IT SOME. THE STORMS WOULD DIMINISH BY
EARLY SUNDAY MORNING AS THE RIDGE BEGINS TO REASSERTS ITSELF FOR
SUNDAY. THIS WOULD BRING A RETURN OF WARMER TEMPERATURES DURING
THE DAY SUNDAY. THIS ALSO WILL PLACE THE REGION UNDER MEAN
SOUTHWESTERLY FLOW...ALLOWING INCREASING MOISTURE TO FILTER INTO
THE AREA.

AS THIS OCCURS LATE SUNDAY AND INTO MONDAY AN UPPER LEVEL STORM
SYSTEM AND ASSOCIATED TROUGH WILL SWINGS INTO THE NORTHERN PLAINS.
AS THE SYSTEM CONTINUES TO MOVE TO THE EAST TUESDAY INTO WEDNESDAY
IT WILL BRING A COLD FRONT THROUGH THE REGION AND BRING THE NEXT
CHANCE FOR SEVERE WEATHER TO THE AREA. THE COMBINATION OF A WARM
AND MOIST AIRMASS AND THE FRONTAL FORCING WILL LIKELY BE ENOUGH
TO PRODUCE STRONG TO SEVERE THUNDERSTORM FOR MUCH OF THE MISSOURI
OZARKS AND EXTREME SOUTHEASTERN KANSAS.

THE COLD FRONT WILL PUSH SOUTH OF THE REGION EARLY WEDNESDAY
HOWEVER THE UPPER LEVEL LOW TAKES ITS TIME MOVING ACROSS THE
NORTHERN PLAINS INTO INTO THE GREAT LAKES REGION INTO THE END OF
THE WEEK. THIS WILL ALLOW THE UPPER LEVEL PATTERN TO SHIFT INTO A
MORE NORTHWESTERN FLOW FOR THE END OF NEXT WEEK AND FOR NEXT
WEEKEND THOUGH IT MAY BE SHORT LIVED AS ANOTHER UPPER LEVEL TROUGH
DIGS INTO THE WEST COAST.

IN GENERAL...IT APPEARS THE AREA WILL BE IN FOR A PERIOD OF ACTIVE
WEATHER FOR THIS WEEKEND AND THE COMING WEEK.

HATCH

&&

.AVIATION...
/ISSUED 1240 AM CDT SAT JUN 18 2011/

FOR THE 06Z TAF PACKAGE...PRIMARY FORECAST CHALLENGE FOR THE NEXT
6 TO 9 HOURS WILL BE THE EVOLUTION OF THUNDERSTORMS ALONG A WARM
FRONT ACROSS EAST CENTRAL KS INTO CENTRAL MO. THE BULK OF THIS
ACTIVITY...AT THIS POINT...LOOKS AS THOUGH IT WILL REMAIN TO THE
NORTH OF JLN/SGF/BBG. HOWEVER...IT IS PLAUSIBLE THAT THIS ACTIVITY
TURNS A BIT TO THE SOUTHEAST WITH TIME...ESPECIALLY AFTER 09Z.
HAVE HANDLED WITH CB AND VCTS FOR THE TIME BEING...BUT WILL UPDATE
IF CONFIDENCE IN OCCURRENCE INCREASES. OTHERWISE EXPECT VFR
CONDITIONS THROUGH MUCH OF SATURDAY INTO SATURDAY EVENING. YET
ANOTHER COMPLEX TSRA IS EXPECTED TO DEVELOP ACROSS EASTERN KS LATE
THIS AFTERNOON AND EVENING AND HAS THE POTENTIAL TO AFFECT THE TAF
SITES THIS EVENING.
