The radar

The Springfield radar (KSGF), 120 km from the middle of the area, began a volume at 20:43 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

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.

The nearest sounding before it

Springfield, MO (KSGF), launched 12:00Z, 8.7 hours before the alert went out and 162 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

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, 3:00 PM CDT, 41 minutes earlier.

Area forecast discussion, Aug 20, 3:00 PM CDT, 41 minutes before

AREA FORECAST DISCUSSION...UPDATE FOR AVIATION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
300 PM CDT MON AUG 20 2007

.DISCUSSION...

MAIN FORECAST CONCERN TODAY IS THE AREA OF HEAVY RAIN SLOWLY
TRAVERSING SOUTHWEST AND SOUTH CENTRAL MISSOURI. THE BACK SIDE OF
THIS ACTIVITY IS QUITE SHARP WITH MODERATE SUBSIDENCE IN ITS
WAKE...AND IT APPEARS IT SHOULD BE OUT OF THE CWA BY EARLY EVENING.
ATTENTION THEN TURNS TO PRECIPITATION CHANCES AND THE ASSOCIATED
TEMPERATURE RESPONSE TOWARD THE END OF THE WEEK.

SHORT TERM (TODAY THROUGH WEDNESDAY)

AS THE REMNANTS OF TROPICAL STORM ERIN EXIT TO THE EAST...SUBSIDENCE
IS OVERTAKING THE AREA IN ITS WAKE AND GIVING A SHARP END TO THE
PRECIPITATION. HAD TO KNOCK TEMPS DOWN QUITE A BIT IN THE RAINY
SECTOR OF THE CWA BUT WE ARE WARMING UP NICELY BEHIND THIS ACTIVITY.
A CUMULUS FIELD HAS BEEN ABLE TO MAINTAIN ITSELF WITH THE NEW FOUND
SURFACE MOISTURE BUT LITTLE MORE IS EXPECTED TO DEVELOP THROUGH THE
EVENING. THE PRESSURE GRADIENT SHOULD REMAIN STRONG ENOUGH TONIGHT
TO KEEP THE LOW LEVELS MIXED...PREVENTING ANY MAJOR FOG FORMATION.
HOWEVER...A SHARP DROP IN WIND SPEEDS TOWARD MORNING COULD LEAD TO
SOME FOG DEVELOPMENT. WILL BE SOMETHING TO WATCH OVERNIGHT.

TEMPERATURES TOMORROW SHOULD REBOUND NICELY INTO THE MID 90S IN THE
ABSENCE OF ANY MAJOR CLOUD COVER. DEWPOINTS WILL REMAIN NEAR 70 IN
THE WESTERN CWA WHICH SHOULD BRING HEAT INDICES INTO THE 100 PLUS
DEGREE RANGE. HOWEVER IT DOES NOT APPEAR TO WARRANT ANY SORT OF HEAT
ADVISORY AT THE MOMENT. LITTLE CHANGES WILL OCCUR BETWEEN TUESDAY
AND WEDNESDAY WITH UPPER PATTERN REMAINING FAIRLY STAGNANT.

LONG TERM (WEDNESDAY THROUGH SUNDAY)

BY FRIDAY EVENING THE UPPER HIGH FLATTENS OUT AND SHIFTS SLIGHTLY
SOUTHEAST. THIS SHOULD ALLOW THE TRAIN OF MID LEVEL WEAKNESSES
CURRENTLY IMPACTING THE MID MISSOURI VALLEY TO SHIFT THEIR
COLLECTIVE TRACKS FARTHER TO THE SOUTH. CURRENT INDICATIONS POINT TO
CYCLOGENESIS ACROSS WESTERN KANSAS FRIDAY AFTERNOON. SOUTH WINDS
WILL BRING A SLIGHT INCREASE TO SURFACE MOISTURE AND OVERALL
INSTABILITY AS THE SYSTEM APPROACHES FRIDAY NIGHT INTO
SATURDAY...BRINGING A CHANCE FOR THUNDERSTORMS INTO THE CWA. AT
PRESENT...SHEAR APPEARS MODEST AT BEST BUT WILL BE MONITORED IN
FUTURE SHIFTS FOR SEVERE POTENTIAL. EXACT TIMING OF PRECIPITATION
AND CLOUDS WILL DICTATE TEMPERATURES. CURRENT FEELING IS THAT LOW
90S WILL PREVAIL AHEAD OF THE SYSTEM WITH UPPER 80S AFTER THE
FRONTAL PASSAGE. 500 HEIGHTS BEGIN A SLOW RISE AGAIN AFTER THIS WAVE
EXITS THE AREA AND IT SHOULD BE FAIRLY QUIET AFTER SATURDAY.

.AVIATION...

FOR THE 18Z TAF PACKAGE...SYSTEM HAS MOVED OFF AND WEAKENED IN
EASTERN MISSOURI LATE THIS MORNING. RADAR SHOWING PRECIP OFF TO THE
EAST OF SPRINGFIELD. HAVE SOME LOW MVFR CEILINGS OVER JOPLIN THAT
HAS SHOWN SIGNS OF LIFTING AND SHOULD BREAK IN THE NEXT HOUR OR SO.
WITH ALL THE MOISTURE ON THE GROUND...NEED TO START THINKING OF
POSSIBLY SOME FOG TOMORROW MORNING. MOS GUIDANCE SHOWING WINDS
REMAINING STRONG FROM THE SOUTH OVERNIGHT...SO ONLY WENT WITH A
SLIGHT REDUCTION IN VISIBILITIES. SHOULD WINDS TAPER OFF EVEN
MORE...THEN FOG WILL BE A GREATER THREAT. WILL CONTINUE TO MONITOR
CONDITIONS.
