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

N. Platte/Lee Bi, NE (KLBF), launched 12:00Z, 7.2 hours before the alert went out and 118 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, Jun 2, 2:30 AM MDT, 10 hours 41 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTH PLATTE NE
330 AM CDT WED JUN 2 2010

.SYNOPSIS...
SURFACE FRONT WELL TO THE SOUTH THIS MORNING...STRETCHED FROM SW KS
TO A CENTRAL IA LOW. SURFACE HIGH PRESSURE CENTERED OVER THE
DAKOTAS. MID LEVEL FLOW IS IN THE MIDDLE OF TRANSITIONING FROM ZONAL
TO NW FLOW. MID LEVEL SHORT WAVE MOVED ACROSS THE STATE
OVERNIGHT...AND NOW IS INTO EASTERN NEB. SECONDARY WEAKER WAVE
PRODUCING SOME LIGHT SHOWERS MOVING ALONG THE CENTRAL NEB/S DAKOTA
BORDER.

&&

.DISCUSSION...
TODAY...DEPARTING SHORT WAVE WILL BRING A BRIEF END TO SHOWERS
LATER THIS MORNING. HOWEVER...AS THE NEXT WAVE...ALREADY REACHING
THE CENTRAL ROCKIES...WILL BE PUSHING INTO THE PANHANDLE BY MID
AFTERNOON. MARGINAL MOISTURE...DEW PTS IN THE MID TO UPPER
50S...WILL RETURN THIS AFTN AHEAD OF NEXTS WAVE. THEN AS THE WAVE
PUSHES ACROSS THE AREA...A BAND OF INSTABILITY IS EXPECTED TO
DEVELOP...WITH CAPE VALUES APPROACHING 800 J/KG...AND LIMITED
AMOUNT...LESS THAN 100 J/KG...OF CIN. SHOULD BE ABLE TO GET SOME
ISOLATED SHOWERS TO DEVELOP IN THE AFTN...FIRST ACROSS THE HIGHER
TERRAIN IN THE PANHANDLE. THE ACTIVE WILL THEN MOVE EAST ONTO THE
PLAINS DURING THE LATE AFTN HOURS...CONTINUING OVERNIGHT.

THURSDAY THE ELONGATED SURF HIGH WILL SHIFT SOUTH INTO THE
MISSOURI RVR VALLEY AND TURN WINDS TO THE SOUTH. THIS WILL RETURN
MORE MOISTURE...DEW PTS IN THE LOWER 60S...DURING THE DAY ON
THURS. NEXT TROF TO PUSH ACROSS THE AREA THURS AFTN. CAP TO
SUPRESS ACTIVITY FOR PART OF THE DAYTIME. BY MID AFTN CAP WILL
BEGIN TO WEAKEN AS HIGHS PUSH INTO THE 80S. SPC HAS MOST OF THE
AREA IN A SLIGHT RISK FOR SVR STORMS. LOCATION OF SVR STORMS WILL
DEPEND ON HOW FAR EAST THE TROUGH MAKES IT BY PEAK HEAT. GFS IS A
LITTLE FURTHER EAST THAN THE NAM...AND BLENDED FOR A FIRST GUESS.
THURSDAY NIGHT THE SYSTEM WILL CONTINUE ACROSS THE STATE WITH A
CONTINUED CHANCE FOR STORMS.

FRIDAY INTO NEXT WEEK WILL CONTINUE TO BE ACTIVE. MAIN FRONT TO
MEANDER JUST TO THE SOUTH OF THE CWA...WITH A CONTINUED TRAIN OF
SHORT WAVES TO RIDE IN WESTERLY/NORTHWESTERLY FLOW. EACH PASSING
WAVE WILL BRING THE CHANCE FOR SHOWERS OR THUNDERSTORMS NEARLY
EVERYDAY...ESPECIALLY IF TIMING IS IN THE AFTN OR EVENING. TIMING
WILL BE KEY TO POTENTIALLY SEVERE WEATHER...AND WILL BE ANALYZED
IN MORE DETAIL AS THE DAYS APPROACH. TEMPERATURES REMAIN SEASONAL
WITH FLUCTUATIONS UP AND DOWN FROM THE LOWER/MID 70S TO THE
LOWER/MID 80S...WARMEST IN THE SOUTHWEST.

&&

.AVIATION...
SCATTERED LIGHT RAINSHOWERS WILL CONTINUE OVER WESTERN AND NORTH
CENTRAL NEBRASKA EARLY THIS MORNING. SOME MVFR CONDITIONS CIGS WILL
CONTINUE OVER SOUTHWEST NEBRASKA EARLY. VFR CONDITIONS TODAY WITH
ISOLATED THUNDERSTORMS MOVING OFF BOUNDARY TO THE WEST LATE THIS
AFTERNOON AND EARLY EVENING. CONFIDENCE NOT HIGH SO WILL LEAVE TRW
OUT OF FORECAST THIS EVENING AT BOTH KLBF AND KVTN.
