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 Jun 1, 2:47 PM CDT, 8 hours 54 minutes earlier.

Area forecast discussion, Jun 1, 2:47 PM CDT, 8 hours 54 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
245 PM CDT FRI JUNE 1 2001

MAIN FOCUS HAS BEEN ON TIMING AND STRENGTH OF STORMS AHEAD OF COLD
FRONT TONIGHT.

CUMULUS HAVE DEVELOPED OVER THE AREA OVER THE PAST COUPLE OF HOURS
AS WE WARMED RAPIDLY INTO THE 70S FROM EARLY MORNING TEMPS NEAR 50.
STRONG TO SEVERE STORMS ARE ALREADY FIRING UP AHEAD OF THE FRONT
THAT EXTENDS FROM NORTH OF DES MOINES TO GOODLAND KANSAS. DEWPOINT
TEMPS ARE INCREASING OVER WESTERN SECTIONS OF THE FORECAST
AREA...BUT 60+ DEWPOINTS REMAIN OFF TO THE WEST. LATEST LAPS DATA
SHOWS LIS BELOW ZERO WEST OF AN OSAGE BEACH TO SPRINGFIELD
LINE...WITH CAPES FROM 100 TO 600 J/KG. ALTHOUGH INSTABILITY IS NOT
FORECAST TO BE TOO IMPRESSIVE BY THE TIME THE STORMS GET HERE (AFTER
03Z) AMPLE LOW LEVEL MOISTURE AND STRONG VORT MAX APPROACHING THE
AREA CONTINUE TO FAVOR LIKELY POPS FOR TONIGHT. 100 KT JET
ACCOMPANYING STORMS WILL ENHANCE DOWNBURST POTENTIAL...ESPECIALLY
OVER NORTHERN AND WESTERN ZONES WHERE BEST DYNAMICS/INSTABILITY WILL
BE LOCATED.

LATEST RUC80 HAS A GOOD HANDLE ON PRECIP FIELD THIS AFTERNOON...WITH
MESOETA NOT PICKING UP ON PRE-FRONTAL PRECIP WELL. REST OF THE
MODELS SEEM TO HAVE A GOOD HANDLE ON FRONT LOCATION AND MOVEMENT. IT
STILL LOOKS LIKE PRECIP WILL REMAIN IN A RATHER NARROW BAND AS FRONT
MOVES QUICKLY THROUGH THE AREA BY 12Z SATURDAY. THEREAFTER...ANOTHER
QUICK RIDGE BUILDS INTO THE REGION...DRYING US OUT TEMPORARILY.

LOOKS LIKE OVERRUNNING PATTERN SETS UP SATURDAY NIGHT OVER THE
SOUTHERN PLAINS...WITH STRONG 850 THETA E ADVECTION SETTING UP OVER
OUR SOUTHWEST ZONES AFTER 06Z. THEREFORE WILL ADD POPS FOR LATE
SATURDAY TO THE SOUTHWEST.

WEATHER PATTERN FOR EARLY NEXT WEEK LOOKS INCREASINGLY WET...AS
FRONT STALLS TO OUR SOUTH AND EVENTUALLY RETURNS NORTHWARD AS A WARM
FRONT SUNDAY/MONDAY. FRONT MAY THEN REMAIN OVER THE AREA THROUGH
TUESDAY AS SURFACE WAVE DEVELOPS OVER THE TEXAS PANHANDLE...AND
PROPAGATES EASTWARD ALONG THE BOUNDARY. THIS PATTERN TYPICALLY
BRINGS FLOODING TO OUR AREA...AND FEAR THAT MODEL QPF MAY BE
UNDERDONE.
