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 Jul 8, 7:07 PM CDT, 6 minutes earlier.

Area forecast discussion, Jul 8, 7:07 PM CDT, 6 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
707 PM CDT SUN JUL 8 2012

...UPDATE TO AVIATION...

...MESOSCALE CONVECTIVE DISCUSSION...

.UPDATE...
/ISSUED 707 PM CDT SUN JUL 8 2012/

CONVECTION CONTINUES TO FESTER ACROSS THE SOUTHERN HALF OF THE
OUTLOOK AREA. A WEAK SHEAR AXIS ALOFT AND A MYRIAD OF OUTFLOW
BOUNDARIES ARE THE FOCI FOR THIS ACTIVITY. BOUNDARIES EARLIER THIS
AFTERNOON SURGED TO THE SOUTH...BUT OVER THE PAST HOUR CONVECTION
HAS FORCED OUTFLOW BOUNDARIES TO HEAD BACK TO THE NORTH. NEEDLESS
TO SAY...THERE ARE SEVERAL MESOSCALE FOCUSING MECHANISMS AROUND
THIS EVENING.

THE ATMOSPHERE IN GENERAL REMAINS UNSTABLE. SURFACE BASED AND
MIXED LAYER CAPE VALUES VARY CONSIDERABLY ACROSS THE REGION...WITH
AREAS PREVIOUSLY UNTOUCHED BY RAINFALL IN THE 1000-2000 J/KG RANGE
WITH MUCH LOWER AMOUNTS IN AREAS AFFECTED BY RAINFALL. LOW LEVEL
LAPSE RATES ARE BEST ACROSS FAR WESTERN MISSOURI AND EXTREME
SOUTHEASTERN KANSAS...AND AS SUCH THERE REMAINS A RISK FOR
LOCALIZED DAMAGING WIND GUSTS FOR A FEW MORE HOURS.

WITH WEAK SHEAR ALOFT...AND RATHER VARIABLE DIRECTION PROFILES IN
THE MID/UPPER LEVELS STORM MOTIONS WILL BE VARIED AND GOVERNED BY
STORM SCALE PROCESSES. SOME WILL MOVE NORTHWARD...OTHERS
SOUTHWARD. EXPECTATIONS ARE THAT COVERAGE AND INTENSITY OF
ACTIVITY WILL GRADUALLY LESSEN WITH TIME DURING THE EVENING...WITH
SOME REDEVELOP POSSIBLE JUST ABOUT ANYWHERE ACROSS THE AREA
OVERNIGHT. WINDOW OF OPPORTUNITY FOR SEVERE WILL BE THE NEXT FEW
HOURS.

.DISCUSSION...
/ISSUED 355 PM CDT SUN JUL 8 2012/

ANOTHER IN HOPEFULLY THE LAST IN A STRING OF VERY HOT DAYS WAS IN
PROGRESS ACROSS THE REGION THIS AFTERNOON. READINGS AT MID
AFTERNOON GENERALLY RANGED FROM THE UPPER 90S TO NEAR 100 DEGREES.

THUNDERSTORM DEVELOPMENT WILL CONTINUE THROUGH THE EARLY EVENING
WITH A GRADUAL INCREASE IN COVERAGE. STORM DEVELOPMENT MAY FOCUS
ALONG TWO AXIS OF CONVERGENCE. ONE AXIS SAGGING SOUTH ACROSS
CENTRAL MISSOURI AND ANOTHER ACROSS FAR SOUTHERN MISSOURI.
ISOLATED STRONG TO SEVERE STORMS MAY DEVELOP WITH DAMAGING WIND
GUSTS AND HAIL TO THE SIZE OF NICKELS. IT APPEARS THE MOST
NUMEROUS THUNDERSTORMS COVERAGE WILL OCCUR FROM SOUTHEASTERN
MISSOURI INTO ARKANSAS ON THE NORTHERN PERIPHERY OF AN MID
CIRCULATION CENTERED OVER EASTERN ARKANSAS. WILL HAVE TO MONITOR
THIS ACTIVITY SPREADING WEST INTO SOUTH CENTRAL MISSOURI.

THE WEAK AND DIFFUSE FRONT STRETCHING WEST TO EAST ACROSS
NORTHERN KANSAS AND MISSOURI WILL SAG SOUTH INTO THE AREA MONDAY
AN UPPER TROUGH BUILDS INTO THE NORTHEASTERN U.S. CONVERGENCE
ALONG THIS FRONT WILL SUPPORT SCATTERED THUNDERSTORM DEVELOPMENT
MONDAY AND MONDAY EVENING MAINLY ALONG AND SOUTH OF INTERSTATE 44.

A MORE SUBSTANTIAL CHANGE IN THE AIR MASS WILL BE EVIDENT TUESDAY
INTO THE MIDDLE OF THE WEEK WITH HIGH TEMPERATURES GENERALLY NEAR
NORMAL. THIS TREND WILL CONTINUE INTO THE WEEKEND. THE CHANCE OF
CONVECTION MAY RETURN TO THE EASTERN OZARKS NEXT WEEKEND.

.AVIATION...
/ISSUED 707 PM CDT SUN JUL 8 2012/

FOR THE 00Z TAFS (JLN/SGF/BBG)...PRIMARY ISSUE WILL REMAIN
SHRA/TSRA BEHAVIOR OVER THE NEXT FEW HOURS. DOWNBURST POTENTIAL AT
SGF/BBG IS LOWER DUE TO THE ATMOSPHERE BEING WORKED OVER. STILL AN
OUTSIDE SHOT AT A STRONG THUNDERSTORM AT JLN...THOUGH AT THIS TIME
THE STRONGEST ACTIVITY REMAINS TO THE WEST OF THE SITE. ACTIVITY
WILL GRADUALLY DECREASE IN INTENSITY AND COVERAGE THROUGH THE
EVENING...THOUGH CANNOT RULE OUT A FEW SHRA LINGERING OVERNIGHT.
WILL ONCE AGAIN BE MONITORING REDEVELOPMENT DURING THE DAY MONDAY.
LOCALIZED DAMAGING WIND GUSTS WILL BE A CONCERN. OVERALL...EXPECT
MAINLY VFR CONDITIONS...BRIEF MVFR/IFR WITH ANY TSRA...AND BRIEF
LIGHT FOG POSSIBLE TOWARD SUNRISE MONDAY...MAINLY AT BBG.
