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

Rapid City, SD (KUNR), launched 12:00Z, 5.7 hours before the alert went out and 191 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.

Area forecast discussion, May 24, 3:10 AM MDT, 8 hours 34 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
410 AM CDT SAT MAY 24 2008

.DISCUSSION...
ABNORMALLY LARGE UPPER LEVEL CUT OFF LOW CONTINUING TO SPIN
ACROSS THE WESTERN CONUS...WITH SEVERAL IMPULSES RIDING ALONG THE
PERIPHERAL OF THE MAIN LOW. THE MAIN LOW IS BREAKING INTO TWO
LOWS THIS MORNING AS BLOCKING HIGH SLOW TO MOVE FROM THE MISS RVR
VALLEY. MODELS IN FAIR AGREEMENT WITH OVERALL PATTERN...HOWEVER
DIFFER SLIGHTLY WITH TIMING AND STRENGTH.

FIRST OFF...THIS MORNING AS WARM FRONT LIFTS NORTH...LOW CLOUDS
AND FOG HAS DEVELOPED. A FEW SITES HAVE DROPPED TO 1/4SM SO WILL
GO WITH A DENSE FOG ADVISORY WITH PACKAGE. ONCE MID LEVEL CLOUDS
ARRIVE FROM WESTERN KS...WOULD EXPECT VSBY TO IMPROVE. NEXT ON THE
TABLE WILL BE WINDS. WILL MONITOR CLOSELY THIS MORNING AS MAY HAVE
TO GO FROM THE FOG ADV TO A WIND ADV. MOS GUIDANCE SUGGEST WINDS
TO BE WELL BELOW ADV...HOWEVER LATEST OBS DESPITE THE FOG
CONTINUES TO BE ABOVE GUIDANCE.

JET STREAK MOVING OVER WESTERN KS...SEEN ON IR IMAGERY...MAY
SPARK A FEW SHRA/TSRA THIS MORNING...HOWEVER MAIN CONCERN WILL BE
THIS AFTERNOON. DRY SLOT WILL LIKELY CREATE BREAKS IN THE CLOUDS
THIS AFTERNOON AND ALLOW FOR DESTABILIZATION TO OCCUR TO THE EAST
OF A STALLING WARM FRONT...CLOSE TO A VTN/BBW LINE. HEAVY RAIN AND
SEVERE THUNDERSTORMS WILL BE POSSIBLE AHEAD/EAST OF THE
FRONT...HOWEVER CANNOT RULE OUT SOME STORMS BEHIND/WEST OF THE
FRONT.

TONIGHT...LOW FINALLY SUPPRESSES THE BLOCKING HIGH TO THE SOUTH
AND WILL MOVE ON TO THE NORTHEAST. DRY AIR TO FUNNEL INTO THE
REGION WITH DRYING CONDITIONS EXPECTED FROM WEST TO EAST. THINK
RESIDUAL SURFACE MOISTURE TO KEEP TEMPS FROM DROPPING AS LOW AS
GUIDANCE...AND LIKE WISE FOR HIGHS INTO SUNDAY.

NEXT SYSTEM TO ARRIVE SUNDAY AFTERNOON...HOWEVER BULK OF THE
ENERGY TO THE SOUTH AND EAST. WILL HAVE TO MONITOR HOW FAR INTO
THE CWA STORMS MAY MAKE IT...HOWEVER CURRENT SYSTEM WILL HELP IN
DETERMINING TRACK OF NEXT SYSTEM.

REMAINDER OF THE FORECAST LOOKING GOOD WITH ACTIVE PATTERN TO
CONTINUE FOR THE HOLIDAY WEEK.

.AVIATION...
TODAY...LOW CLOUDS AND FOG ASSOCIATED WITH COOL MOIST AIR REMAINS
ACROSS THE FCST AREA. ALL MODEL DATA INDICATES A WARM FRONT DRAPED
