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 Aug 20, 3:47 AM CDT, 2 hours 41 minutes earlier.

Area forecast discussion, Aug 20, 3:47 AM CDT, 2 hours 41 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
347 AM CDT SAT AUG 20 2011

.DISCUSSION...

A COMPLEX OF THUNDERSTORMS CONTINUES TO ADVANCE EAST SOUTHEAST
ACROSS NORTHWESTERN MISSOURI THIS MORNING. THIS AREA OF CONVECTION
IS EXPECTED TO CONTINUE TO TRACK EAST SOUTHEAST ACROSS CENTRAL AND
SOUTHERN MISSOURI THROUGH DAYBREAK. EARLIER...THESE STORMS WERE
CAPABLE OF STRONG STRAIGHT LINE WINDS AND HAIL UP TO THE SIZE OF
QUARTERS AND ARE STILL CAPABLE OF STRONG TO SEVERE STRAIGHT LINE
WINDS.

MAIN FORECAST CONCERN CONTINUES TO BE THE STORM MOTION AND TIMING
OF THE MCS INTO THE FORECAST AREA. STORMS HAVE CONTINUED TO
TAKE ON AN EAST SOUTHEAST TRACK THIS EVENING. THIS IS SUPPORTED
BY SOUTHEASTWARD ORIENTED CORFIDI AND FORWARD PROPAGATING CORFIDI
VECTORS. CONVECTION CONTINUES TO BE SLIGHTLY ELEVATED IN
NATURE...AS THE STORMS MIGHT BE A LITTLE COLD POOL DOMINANT WITH
ONLY APPROXIMATELY 15 TO 20 KTS OF 0-3 KM SHEAR AVAILABLE AND COLD
POOL STRENGTH OF APPROXIMATELY 25 KTS. AS THE CONVECTION NEARS
CENTRAL MISSOURI IT WILL LIKELY FOLLOW THE MORE SOUTHEASTWARD
TRACK OF THE FORWARD PROPAGATING CORFIDI VECTORS GIVEN THE
SLIGHTLY BETTER REGION OF INSTABILITY AND THE DECENT RIDGE OF
HIGHER THETA E AIR EXTENDING INTO THE OZARKS. THE MAIN LINE
SEGMENT CONTINUES TO SHOW SIGNS OF WEAKENING AS IT MOVES SOUTH
HOWEVER AND IS MOST LIKELY DUE TO THE COLD POOL DOMINANCE. AS THE
COMPLEX CONTINUES TO MOVE SOUTHEASTWARD IT WILL ENCOUNTER
DECREASING 0-3 KM SHEAR VALUES. THIS WILL CONTINUE TO AID IN
WEAKENING THE LINE AS IT MOVES INTO THE FORECAST AREA. WINDS
ASSOCIATED WITH THIS LINE WILL CONTINUE TO BE STRONG UNDER THE
STRONGEST PORTION OF THE LINE...BUT THE SEVERE WIND THREAT WILL
CONTINUE TO DIMINISH THROUGH THE EARLY MORNING.

THE MCS WILL CONTINUE TO TRACK EAST SOUTHEAST ACROSS CENTRAL
MISSOURI THROUGH DAY BREAK. WILL KEEP LIKELY POPS ACROSS THE FAR
NORTHEASTERN COUNTIES THROUGH 12Z AS THE SYSTEM MOVES SOUTH
SOUTHEAST ACROSS THE EASTERN OZARKS. WENT AHEAD AND KEPT CHANCE
POPS ACROSS THE NORTHEAST FOR ANY DEVELOPMENT BEHIND THE MAIN
LINE...MUCH LIKE FRIDAY MORNING.

TEMPERATURES WILL ONCE AGAIN BE A CHALLENGE TODAY AS AREAS UNDER
HEAVY CLOUD COVER FROM THIS MORNINGS MCS WILL BE SLOW TO WARM.
AREAS MAINLY EAST OF THE HIGHWAY 65 CORRIDOR WILL SEE TEMPS RISE
INTO THE UPPER 90S WITH LOWER 100S POSSIBLE ACROSS FAR
SOUTHWESTERN MISSOURI. LOCATIONS TO THE EAST WILL BE THE ONES SLOW
TO RECOVER WITH HIGHS FORECAST TO REACH THE MID 80S TO LOWER 90S.

FOR THE REMAINDER OF THE WEEKEND INTO NEXT WEEK...MID AND LONG
RANGE GUIDANCE CONTINUES TO SHOW DECENT AGREEMENT WITHIN THE LARGE
SCALE PATTERNS. THE UPPER LEVEL RIDGE WILL REMAIN ORIENTED OVER
THE INTER-MOUNTAIN WEST WITH A SLIGHTLY AMPLIFIED RIDGE AXIS OVER
THE ROCKIES. THIS WILL KEEP PLAINS AND LOWER MISSOURI RIVER VALLEY
REGIONS UNDER NORTHWEST FLOW THROUGH THE MIDDLE OF NEXT WEEK. THIS
WILL ALLOW A SERIES OF UPPER LEVEL WAVES TO MOVE THROUGH THE REGION
NEARLY EVERY DAY...WITH EACH INTRODUCING A CHANCE FOR
PRECIPITATION. TEMPERATURES WILL REMAIN FAIRLY CONSTANT...WITH
HIGHS EACH DAY RISING INTO THE UPPER 80S TO LOWER 90S ACROSS THE
EAST TO THE MID TO UPPER 90S ACROSS OUR WESTERN COUNTIES. WHILE
LOWS EACH NIGHT WILL DROP INTO THE LOW TO MID 70S.

.AVIATION...

FOR THE 06Z KSGF...KJLN AND KBBG TAFS...MAIN AVIATION CONCERNS
OVERNIGHT INTO SATURDAY WILL BE ON CONVECTION POTENTIAL.
CONVECTION IS CURRENTLY PUSHING ACROSS NORTHEASTERN KANSAS AND
NORTHWESTERN MISSOURI LATE THIS EVENING. THIS ACTIVITY WILL SLIDE
TO THE SOUTHEAST OVERNIGHT INTO SATURDAY MORNING. THE MAJORITY OF
THIS ACTIVITY SHOULD REMAIN NORTH AND EAST OF THE TAFS SITES
OVERNIGHT...BESIDES POSSIBLE KSGF WHERE THE WESTERN EDGE OF THIS
ACTIVITY MAY CLIP THIS SITE AREA.

ADDITIONAL STORMS MAY THEN BE POSSIBLE SATURDAY AFTERNOON AS A WEAK
FRONTAL BOUNDARY SLIDES THROUGH THE AREA.
