Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

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 Nov 6, 2:28 AM CST, 16 minutes earlier.

Area forecast discussion, Nov 6, 2:28 AM CST, 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
228 AM CST THU NOV 6 2008

.DISCUSSION...

MAIN FOCUS FOR THIS FORECAST PERIOD WILL BE WITH STRONG STORM
SYSTEM CURRENTLY AFFECTING THE FORECAST AREA.

STRONG 100-120KT UPPER LEVEL JET PUNCHING INTO SOUTHEAST KANSAS
AND THE SOUTHWEST CORNER OF MISSOURI. THIS AIDED IN STORMS RAMPING
BACK UP OVER THE LAST COUPLE OF HOURS. A FEW STORMS EMBEDDED
WITHIN THE MAIN LINE HAVE HAD DECENT ROTATION REQUIRING TORNADO
WARNINGS. 0-1KM HELICITIES OF 450-500 M2/S2 EAST OF THE FRONT SO
WILL STILL NEED TO MONITOR FOR ROTATING STORMS WITHIN THE LINE.
MAIN LINE OF CONVECTION WILL LIKELY BEGIN TO WEAKEN OVER THE NEXT
COUPLE OF HOURS BUT WILL STILL HAVE THE POTENTIAL OF BEING SEVERE
OVER THE EASTERN MISSOURI OZARKS THROUGH THE EARLY MORNING.

MOST OF THE CONVECTION WILL LIKELY BE EXITING THE CWA BY 12Z...BUT
WILL CONTINUE CHANCES FOR 12-18Z FORECAST PERIOD OVER THE EASTERN
MOST COUNTIES. DRIER AIR WILL BEGIN TO PUNCH INTO THE AREA FROM
THE SOUTHWEST DURING THE DAY WITH MOSTLY SUNNY SKIES EXPECTED
DURING THE AFTERNOON OVER MOST OF THE AREA.

WRAP AROUND MOISTURE WILL BEGIN TO ENTER BACK INTO THE AREA LATE
TONIGHT INTO FRIDAY SPREADING CLOUD COVER BACK TO ABOUT THE
NORTHEAST 2/3 OF THE CWA. NORTHEAST SECTIONS OF THE CWA WILL
LIKELY HAVE THE MOST CLOUD COVER AND WILL SEE TEMPERATURES
STRUGGLE TO REACH THE LOW 50S. COULD SEE UPPER 50S TO NEAR 60 OVER
THE SOUTHWEST PORTION OF THE CWA WITH MORE POTENTIAL OF SUNSHINE.
HAVE THROWN IN SOME LOW POPS IN CENTRAL MO WHERE MOISTURE DEPTH
WILL BE MORE SIGNIFICANT AND BETTER LIFT WILL BE POSSIBLE AS UPPER
SHORTWAVE ROTATES THROUGH. ANY PRECIPITATION SHOULD REMAIN LIGHT.

CLOUDS SHOULD BEGIN TO PULL OUT BY FRIDAY NIGHT INTO SATURDAY. BY
SATURDAY NIGHT ANOTHER STRONG JET STREAK WILL BEGIN TO ENTER THE
WEST COAST. THE ECMWF DIGS THE SYSTEM DEEPER INTO THE SOUTHERN
PLAINS THAN THE GFS AND THE 00Z RUN WAS PRETTY CONSISTENT WITH THE
12Z MODEL RUN. AS A RESULT...THE ECMWF KEEPS THE PRECIPITATION
FURTHER TO THE SOUTH UNTIL LATE MONDAY NIGHT INTO TUESDAY WHILE
THE GFS BRINGS PRECIPITATION INTO THE AREA BY SUNDAY NIGHT INTO
MONDAY. BECAUSE OF THE SIGNIFICANT DIFFERENCES...HAVE GONE MORE
CONSERVATIVE ON POPS AT THE ONSET AND HAVE BUMPED UP POPS TO 40S
BY MONDAY INTO MONDAY NIGHT. FOR NOW WILL KEEP PRECIPITATION AS
ALL RAIN...HOWEVER GFS IS SHWOING MUCH COOLER TEMPERATURES AT 850
BY LATE MONDAY INTO MONDAY NIGHT OVER THE WESTERN CWA AND WILL
NEED TO MONITOR FOR THE POTENTIAL OF SNOW.

LINDENBERG

&&

.AVIATION...

FOR THE 06Z TAFS...WILL CONTINUE TO INCLUDE WIND SHEAR IN TAFS
THROUGH THE NIGHT BASED ON LATEST WIND PROFILER DATA. LINE OF
STORMS PERSISTING NEAR THE MO/KS BORDER FOR THE PAST SEVERAL HOURS
IS FINALLY SHOWING SIGNS OF EASTWARD MOVEMENT AS SQUALL LINE
BEGINS TO DEVELOP...SO WILL CONTINUE VICINITY THUNDER WITH
EMBEDDED TEMPO FROM AROUND 06-10Z.

MAIN WIND SHIFT WITH COLD FRONT PASSAGE IS EXPECTED BY MID/LATE
MORNING WITH DRY SLOT CLEARING OUT CLOUD COVER BY EARLY AFTERNOON.
