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 May 27, 3:34 PM CDT, 1 hour 11 minutes earlier.

Area forecast discussion, May 27, 3:34 PM CDT, 1 hour 11 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
334 PM CDT FRI MAY 27 2011

.DISCUSSION...
/ISSUED 253 PM CDT FRI MAY 27 2011/

A LOW AMPLITUDE SHORTWAVE MOVING EAST INTO THE FAR SW MO/NW AR
REGION COUPLED WITH ISENTROPIC LIFT AND INCREASED MOISTURE
ADVECTION ALONG WITH MUCAPES OF 500-1000 J/KG HAS LED TO A SMALL
CLUSTER OF STRONG TO MARGINALLY SEVERE TSTMS OVER THE
SOUTHERN/SOUTHWEST CWFA...WITH HAIL THE MAIN ISSUE. STORMS ARE NOW
OUTRUNNING THE STRONGER INSTABILITY...SO EXPECTED A DOWNTICK IN
UPDRAFT STRENGTH.

ADDITIONAL STORMS ARE EXPECTED TONIGHT/OVERNIGHT...MAINLY AFTER
MIDNIGHT...AS LIFT INCREASES AGAIN WITH AN IMPULSE APPROACHING
THE REGION...INCREASED ASCENT WITH A MODESTLY INCREASING LOW LEVEL
JET...AN APPROACHING WARM FRONT FROM THE SOUTH...AND ELEVATED
MUCAPES OF 1000-1500 J/KG. AREA IS STILL UNDERNEATH FAIRLY STRONG
MID LEVEL FLOW WITH 40KT 0-6KM BULK SHEAR FOR STORM ORGANIZATION.
THE MAIN THREAT WILL BE LARGE HAIL GIVEN THE ELEVATED NATURE OF
THE CONVECTION.

SOME STORMS MAY RE-FIRE OR BE ONGOING ON SATURDAY...ESPECIALLY
OVER THE NORTHERN CWFA WHERE MOISTURE ADVECTION IS EXPECTED TO BE
MAXIMIZED. OTHERWISE...THE OVERALL TRANSITION TO A MORE SUMMERTIME
PATTERN IS STILL EXPECTED AS A RIDGE BUILDS FROM THE GULF OF
MEXICO TO THE MID ATLANTIC...THEN GRADUALLY SHIFTS NORTH...PUSHING
THE MAIN STORM TRACK WEST AND NORTH OF THE REGION BY EARLY NEXT WEEK.
MAX TEMPERATURES COULD TOUCH LOW 90S IN SOME AREAS NEXT WEEK. A
SMALL CHANCE FOR PRECIP MAY EXIST AS A SHORTWAVE MOVES NORTHEAST
FROM THE CENTRAL/NORTHERN ROCKIES INTO THE NORTHERN PLAINS AND
UPPER MIDWEST DURING THE MON-TUE PERIOD WITH THE TAIL END OF A
WEAK FRONT TRYING TO EDGE INTO THE AREA TUE. UPPER RIDGING IN
PLACE WILL LIKELY LIMIT PRECIP CHANCES TO A GREAT EXTENT.

DSA

&&

.AVIATION...

CURRENTLY AN ELEVATED LINE OF CONVECTION HAS DEVELOPED ALONG A
DISTURBANCE ACROSS EASTERN KANSAS AND WESTERN MISSOURI. AS THIS
CONVECTION LIFTS NORTH NORTHEAST ACROSS SOUTHWEST MISSOURI IT WILL
IMPACT ALL THREE TAF SITES THIS AFTERNOON. EXPECTING A LULL IN
CONVECTION ONCE THIS LINE MOVES THROUGH LATE IN THE AFTERNOON AND
EARLY EVENING BEFORE A WARM FRONT LIFTS NORTH ACROSS THE MISSOURI
ARKANSAS BORDER AND ONCE AGAIN BRINGS SHOWERS AND THUNDERSTORMS
ACROSS THE REGION IMPACTING ALL THREE SITES AGAIN. PINPOINTING THE
EXACT TIMING AND LOCATION OF STORMS WILL BE NEXT TO
IMPOSSIBLE...THEREFORE HAVE MENTION OF VCTS AND VCSH THROUGH THE
OVERNIGHT AND EARLY SATURDAY MORNING. EXPECTING VFR CEILINGS AND
VISIBILITIES TO PREVAIL THROUGH MOST OF THE TAF PERIOD...HOWEVER
AN MVFR STRATUS DECK CONTINUES TO HOVER OVER BBG...AND IS EXPECTED
TO PREVAIL THROUGH MOST OF THE AFTERNOON. COULD SEE MVFR OR IFR
CONDITIONS IF ANY SITE IS DIRECTLY IMPACTED BY A THUNDERSTORM.
