Thunderstorms produced two EFO tornadoes in Nodaway County, in the late morning hours of April 24, 2010. These tornadoes were more like land spouts and only caused minor tree limb damage.

The episode as NWS EAX wrote it up.
Thunderstorms produced two EFO tornadoes in Nodaway County, in the late morning hours of April 24, 2010. These tornadoes were more like land spouts and only caused minor tree limb damage.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Kansas City, MO wrote its last area forecast discussion before the first event at Apr 24, 9:45 AM CST, 1 hour 52 minutes earlier.
AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE KANSAS CITY/PLEASANT HILL MO
1045 AM CDT SAT APR 24 2010
...CORRECTION TO ENDING TIME OF FLOOD WATCH...
.UPDATE...
WILL BE ISSUING A FLOOD WATCH FOR PORTIONS OF CENTRAL MISSOURI FOR
THIS AFTERNOON INTO THE EVENING PERIOD AS EXPECTING A FAIRLY LONG
TERM RAIN EVENT ACROSS THIS AREA WHERE HEADWATER GUIDANCE NUMBERS
ARE FAIRLY LOW FOR AREA RIVERS. MAY ALSO PRODUCE SOME MINOR FLASHIER
TYPE FLOODING ON SOME OF THE TRIBUTARIES...BUT MAIN CONCERN IS THAT
WE WILL LIKELY HAVE TO ISSUE WARNINGS FOR SOME OF THE RIVERS IN THE
REGION IF THE EXPECTED QPF DEVELOPS AS THE UPPER LOW INTENSIFIES TO
OUR EAST. IF THIS WERE WINTER...WOULD BE WORRIED ABOUT A DECENT
DEFORMATION BAND OF SNOW...SO GLAD WE HAVE SPRING TIME TEMPERATURES.
REGARDING TEMPERATURES...HAVE LOWERED HIGH TODAY WHERE CLOUDS AND
PRECIPITATION SHIELD WILL HOLD TEMPERATURES IN CHECK. ONLY NORTHWEST
MISSOURI AND NORTHEAST KANSAS SHOULD SEE ENOUGH SUNSHINE TO BOOST
TEMPERATURES A BIT THIS AFTERNOON.
ALSO HAVE INCREASED WINDS IN EASTERN PARTS OF THE FORECAST AREA THIS
AFTERNOON AS THE SURFACE LOW MOVES NORTHEAST INTO EASTERN MISSOURI.
DEPENDING ON HOW MUCH DEEPENING THIS SYSTEM DOES...WINDS COULD GET
PRETTY GUSTY IN THOSE AREAS THIS AFTERNOON AND EARLY EVENING.

.DISCUSSION...
/420 AM CDT SAT APR 24 2010/
INTERESTING STUFF GOING ON IN THE UPPER LEVELS. WATER VAPOR LOOP
SHOWS THE MAIN UPPER LEVEL LOW PRESSURE AREA SPLITTING INTO TWO
DISTINCT CIRCULATIONS...ONE ROTATING NORTHWESTWARD OVER
NEBRASKA...THE OTHER EASTWARD OVER SOUTHERN KANSAS. ALSO SEE A
CONVECTIVELY INDUCED LOW PRESSURE AREA MOVING NORTHEAST INTO
ARKANSAS. THIS ONE IS AIDED BY A FAIRLY STRONG UPPER LEVEL JET MAX
AND WILL LIKELY BECOME THE STRONGER LOBE OF THE MULTI-LOBE UPPER
LEVEL LOW. WATER VAPOR IMAGERY SHOWS PLENTY OF DRY AIR WRAPPED INTO
THE WESTERN SYSTEMS ALOFT. AT THE SURFACE...LOW LEVEL MOISTURE
REMAINS IN PLACE ACROSS ALL BUT THE EXTREME NORTHWEST PORTION OF
MISSOURI OVERNIGHT...WITH DEW POINTS MAINLY IN THE LOWER 60S.
SFC-850MB TRAJECTORIES SUGGEST THIS MOISTURE WILL REMAIN IN PLACE
THROUGH AT LEAST MIDDAY...WHEN THE SFC LOW DEEPENS SOUTHEAST OF THE
FORECAST AREA THEREBY REFOCUSING SFC-850MB WINDS. MEANWHILE...THE
BROAD UPPER LEVEL LOW WILL BE MOVING OVERHEAD AROUND MIDDAY. THIS
WILL LIKELY GIVE A FAIRLY NARROW TIME FRAME OF 16-20Z FOR BEST CAPE
AND BEST SHEAR TO INTERACT ACROSS THE AREA. WHILE THIS WOULD BE THE
BEST TIME FOR STRONG TO SEVERE STORMS...NUMEROUS SHOWERS AND
THUNDERSTORMS ARE EXPECTED ACROSS THE REGION DUE TO BROAD SCALE LIFT
ASSOCIATED WITH THE PROXIMITY OF THE UPPER LOW AND DAYTIME HEATING.
THE UPPER LOW WILL CONTINUE TO MOVE EAST OF THE REGION ON SUNDAY.
HOWEVER MODELS CONTINUE TO SHOW A VORT LOBE ROTATING AROUND THE
BROAD UPPER SYSTEM...SO WILL HOLD ON TO THE CHANCE OF SHOWERS
THROUGH SUNDAY...GRADUALLY ENDING SUNDAY NIGHT.
A BRIEF PERIOD OF UPPER RIDGING WILL MOVE THROUGH THE REGION ON
MONDAY MORNING...BUT ANOTHER SHORT WAVE DROPPING SOUTHEAST OUT OF
WESTERN CANADA WILL BE ARRIVING BY MONDAY NIGHT AND INTO TUESDAY.
THIS SYSTEM WILL BE ACTING MORE LIKE A WINTERTIME CLIPPER TYPE
SYSTEM...WITH THE BETTER CHANCE OF SHOWERS TO THE NORTH AND EAST OF
THE LOW. AT THIS POINT WILL JUST GO WITH LOW POPS AS THE TIMING OF
THIS SYSTEM AND EXACT TRACK IS STILL A BIT UNCERTAIN.
FURTHER OUT...A PERIOD OF STRONGER UPPER RIDGING WILL BE MOVING
THROUGH MIDWEEK...BUT ANOTHER STRONGER SHORT WAVE WILL BE MOVING
ONSHORE IN THE WEST...AND IS EXPECTED TO BECOME A PLAYER IN OUR
WEATHER TOWARD THE END OF THE WEEK. THIS SYSTEM MAY HAVE THE
POTENTIAL OF SETTING OFF STRONG STORMS IN THE REGION LATER ON
THURSDAY AND INTO FRIDAY...SO IT LOOKS LIKE ANOTHER ROUND OF
SPRINGTIME WEATHER.

.AVIATION...
/645 AM CDT SAT APR 24 2010/
FOR THE 12Z TAFS...IFR STRATUS POISED ON THE DOORSTEP OF ALL THREE
TAF SITES THIS MORNING. DEVELOPING SURFACE LOW PRESSURE SYSTEM
OVER NORTHWEST ARKANSAS WILL RESULT IN BACKING AND STRENGTHENING LOW
LEVEL FLOW IN THE NEXT FEW HOURS...WHICH SHOULD DRAW THE STRATUS
NORTHWEST INTO THE TERMINAL SITES BY 13-14 UTC. NEXT AVIATION IMPACT
WILL BE FROM SCT SHRA AND TSRA DEVELOPING BY LATE MORNING...AS
INDICATED BY NAM BUFR AND RUC FORECAST SOUNDINGS. WITH COLD CORE
LOW MOVING ACROSS...ANTICIPATE ISOLATED TSRA ALSO DEVELOPMENT...BUT
UNSURE OF COVERAGE. DECIDED TO CARRY VCSH IN ALL THREE TERMINAL
SITES BETWEEN 24/16UTC AND 25/01Z...AND COVERED ISOLD TSRA
DEVELOPMENT WITH CB GROUP. CONVECTIVE THREAT SHOULD WANE BY
EARLY THIS EVENING...WITH STRATUS BUILDING INTO ALL THREE
TERMINALS FOR THE REST OF THE OVERNIGHT HOURS.
