Local storm reports filed while the alert was in force, from inside its polygon or its counties.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado 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.

Area forecast discussion, May 16, 2:32 PM CDT, 5 hours 5 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HASTINGS NE
232 PM CDT SUN MAY 16 2004

.SHORT TERM...TONIGHT THRU TUE NIGHT. NO SIG CHANGES TO FCST. AT
SFC...RAPIDLY DEVELOPING LOW OVR SERN CO WITH WARM FRONT EXTENDING
FROM ERN CO THRU NWRN KS...E THRU SRN NE...THEN NORTHEAST INTO NERN
NE. COLD FRONT FROM SWRN MN SWWD THRU NRN NE...INTO ERN WY AND ON UP
TO SRN MT. WEAK DRYLINE FROM WRN NE INTO NERN CO AND ANOTHER
STRONGER DRYLINE FROM SERN CO LOW INTO ERN NM. CONVERGENT BOUNDARY
EXTENDS FROM WRN DAWSON COUNTY THRU NRN BUFFALO...SHERMAN AND HOWARD
COUNTIES...THEN ON UP NORTH.

WIND ADVISORY FOR ALL OF FA...WITH S WINDS INCREASING...BUT NOT
QUITE AT ADV LVL JUST YET. EXPECTING STRONGEST WINDS HOWEVER BETWEEN
3 AND 7 PM...SO STILL WAITING. OTHERWISE...AREA FROM SRN BORDERS OF
SHERMAN AND HOWARD COUNTIES MOST LIKELY AREA FOR POSSIBLE STORM
INTENSIFICATION THIS AFTERNOON WITH 60 DEW PTS...WEAKENING CAP...AND
BEST LL FORCING IN THIS AREA. OTHERWISE ONGOING CONVECTION ELEVATED
AT THE MOMENT. SPACE PICS HAVE LEAD SHORTWAVE JUST NOW OVR SERN WY
AND ERN CO. BETTER CHANCES FOR MORE WIDESPREAD TSRA ACTION WILL COME
LATER IN EVENING AS WAVE KICKS OVRHEAD. SCATTERED CLOUDS LEFT FROM
THIS MORNINGS ACTION HAS HELPED TO KEEP TEMPS A BIT COOLER...IN
ADDITION TO KEEPING THE LID ON THINGS A BIT LONGER WITH STABLE AREA
AT LOW LVLS...DESPITE EVER INCREASING INSTABILITY ALOFT. SO ISOLATED
TO SCATTERED CHANCES AROUND THRU REST OF AFTERNOON AND OVERNIGHT.

FOR MON AND TUE...CHANCES FOR THUNDERSTORM CONTINUE EACH DAY...WITH
SFC FRONT/BOUNDARY HANGING UP ONCE AGAIN ACROSS CWA MON...AND JUST
TO SOUTH OF FA ON TUE...SO CONTINUING CHANCES SEEM GOOD...AS QUICK
MOVING WAVES SKIRT THROUGH NEARLY ZONAL UPR LVL PATTERN. TEMPS ON
SEASONAL SIDE...AND JET HANGING OUT JUST TO NORTH OF AREA WILL KEEP
THINGS INTERESTING.

.LONG TERM...12Z WEDNESDAY TO SUNDAY...ONCE AGAIN THE CHANCE OF
PRECIPITATION IS THE MAIN CONCERN DURING THIS PORTION OF THE
FORECAST. SEVERAL WEAK SHORT WAVES MOVE ACROSS THE AREA ON SOUTHWEST
FLOW. STRONGEST WAVES ARE THURSDAY NIGHT AND SATURDAY NIGHT. FROM A
SURFACE STAND POINT...LOW PRESSURE DEVELOPS ALONG THE LEE OF THE
ROCKIES...MOVES EAST WITH A FRONTAL BOUNDARY TO THE EAST WHICH SINKS
SOUTH ACROSS THE FORECAST AREA BEFORE THE NEXT LOW PRESSURE DEVELOPS
ALONG THE LEE OF THE ROCKIES. THIS PATTERN REPEATS ITSELF DURING THE
FORECAT PERIOD. THE TIMING AND THE LOCATION OF THE SURFACE FRONT
WILL BE PART OF THE DEPENDANT FACTORS ON THUNDERSTORM CHANCES.

THE FIRST OCCASION OF THE FRONT MOVING ACROSS THE FORECAST AREA IS
WEDNESDAY NIGHT. WITH THE UPPER WAVE MOVING IN ALONG WITH IT...HAVE
A CHANCE OF THUNDERSTORMS ACROSS THE AREA. SATURDAY NIGHT INTO
SUNDAY IS THE NEXT TIME THAT A FRONTAL BOUNDARY SINKS ACROSS THE
FORECAST AREA...COINSIDING WITH THE NEXT WAVE OF UPPER LEVEL
SUPPORT. IN BETWEEN...THERE IS ENOUGH MOISTURE AROUND THAT THE WEAK
UPPER LEVEL WAVES THAT MOVE THROUGH HAVE THE POTENTIAL TO PRODUCE
SOME SHOWERS...SO HAVE SLIGHT CHANCES FOR MOST OF THE AREA MUCH OF
THE PERIOD.

TEMPERATURES CAUSE SOME CONCERN DURING THE PERIOD. WITH CHANCES OF
PRECIPITATION AND SOME CLOUD COVER...TEMPERATURES WOULD TEND TO BE
LOWER. ON THE OTHER HAND...THERE WILL BE SOME SUN AND TEMPERATURES
AT 850MB ARE RELATIVELY WARM. HAVE OPTED TO GO SLIGHTLY ABOVE
GUIDANCE DUE TO THE POWER OF THE MID-MAY SUN AND RELATIVELY WARM AIR
AT 850MB.
