What forecasters said that day

The local office's own words before this flash flood 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 flash flood warning went out at May 1, 2:48 PM CDT, 34 minutes earlier.

Area forecast discussion, May 1, 2:48 PM CDT, 34 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPRINGFIELD MO
248 PM CDT FRI MAY 1 2009

.DISCUSSION...

A LARGE COMPLEX OF CONVECTION WAS SHIFTING EAST ACROSS THE OZARKS
THIS AFTERNOON AND SHOWING AN OVERALL WEAKENING TREND. HOWEVER A
CLUSTER OF STRONG STORMS PERSISTED ACROSS NORTHEAST OKLAHOMA. THIS
ACTIVITY HAS BEEN SUPPORTED BY A MINOR SHORTWAVE TRACKING EAST OUT
OF SOUTHERN KANSAS...A VEERED LOW LEVEL JET IMPINGING ALONG A
FRONT NOW STALLING ALONG THE MISSOURI ARKANSAS BORDER...AND UPPER
LEVEL DIFFLUENCE.

A COLD FRONT THAT SAGGED SOUTH ACROSS THE AREA TODAY WILL STALL
ACROSS NORTHERN ARKANSAS UNDERNEATH A QUASI-ZONAL FLOW. UPPER
LEVEL DISTURBANCES WILL CONTINUE TO MOVE EAST ALONG THE BOUNDARY
PRODUCING ADDITIONAL ROUNDS OF SHOWERS AND THUNDERSTORMS...AND THE
CONTINUED RISK OF HEAVY RAINFALL AND FLOODING.

EXPECT RAINFALL TO DIMINISH LATE THIS AFTERNOON AND EVENING BUT
INCREASE AGAIN LATER TONIGHT AS THE LOW LEVEL JET STRENGTHENS AND
INTERSECTS THE FRONT. GOOD LOW LEVEL MOISTURE CONVERGENCE AND
ISENTROIC ASCENT WILL DEVELOP OVER TOP THE FRONTAL ZONE. THIS
SCENARIO IS EXPECTED TO PERSIST THROUGH THE DAY SATURDAY AS A MORE
DEFINED SHORTWAVE SLIDES INTO THE REGION. THE RESULT WILL BE MORE
WIDESPREAD RAINFALL.

850 DEWPOINTS OF 10 TO 14 DEGREE CELSIUS AND PRECIPITABLE WATER
VALUES APPROACHING 1.5 INCHES WILL SUPPORT EFFICIENT RAINFALL.
ADDITIONAL RAINFALL AMOUNTS OF ONE TO TWO INCHES WILL BE COMMON
PARTICULARLY ACROSS FAR SOUTHERN MISSOURI WITH LOCALLY HEAVIER
AMOUNTS. WITH SATURATED SOILS AND ONGOING FLOODING...FLASH
FLOODING WILL BE A MAJOR CONCERN. THE FLASH FLOOD WATCH CONTINUES
INTO SUNDAY. THE RISK FOR SEVERE STORMS WILL BE VERY LOW AND
CONFINED TO AREAS NEAR THE ARKANSAS BORDER.

ONE LAST PRIMARY SHORTWAVE WILL LIFT INTO THE AREA SUNDAY WITH
SURFACE LOW DEVELOPMENT ACROSS THE LOWER MISSISSIPPI RIVER VALLEY.
WE WILL LIKELY SEE LINGERING SHOWERS TAPER OFF DURING THE DAY AND
MODELS HAVE TRENDED SHIFTING RAINFALL SOUTHEAST OF THE AREA.
TEMPERATURES WILL REMAIN COOL ALL WEEKEND AS CLOUDS AND A
NORTHEAST WIND PERSIST.

A BREAK IN THE ACTION IS EXPECTED EARLY NEXT WEEK. HOWEVER MORE
ACTIVE WEATHER WILL RETURN THE MIDDLE OF NEXT WEEK.

FOSTER

&&

.AVIATION...

A FRONT HAS MOVED ACROSS THE AREA AND STALLED ALONG THE ARKANSAS
BORDER. MEANWHILE A SERIES OF UPPER LEVEL DISTURBANCES WILL
CONTINUE TO TRACK ACROSS THE REGION. MULTIPLE ROUNDS OF SHOWERS
AND THUNDERSTORMS WILL IMPACT THE SPRINGFIELD AND JOPLIN
TERMINALS THROUGH TONIGHT. MVFR CONDITIONS WILL BECOME PREVALENT WITH
AREAS OF IFR CEILINGS. VISIBILITIES WILL LOWER INTO MVFR AND
PERHAPS IFR CATEGORY AT TIMES WITHIN AREAS OF RAINFALL.
