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, 5.5 hours before the alert went out and 73 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

400 AM CDT SAT MAY 28 2005

...FORECAST CHALLENGE WILL BE THUNDERSTORM ACTIVITY TEMPERATURES OVER
THE HOLIDAY WEEKEND...

.DISCUSSION...
SURFACE HIGH PRESSURE OVERHEAD COMBINING WITH DRY AIR AND NO CLOUDS
TO PRODUCE GOOD RADIATION AND NEAR RECORD COLD TEMPERATURES THIS
MORNING. AS THE SURFACE HIGH MOVES SOUTHEAST...RETURN SOUTH FLOW
WILL USHERING IN HIGH DEW POINTS. CLOUDLESS SKIES WILL ALLOW FOR A
QUICK WARM UP THIS MORNING...THEN AS MOISTURE INCREASE A GOOD
CU FIELD WILL DEVELOP. BY PEAK HEATING AN UPPER LEVEL WAVE WILL DRIFT
ACROSS THE REGION GIVING THE FINAL KICKER FOR SHOWERS AND
THUNDERSTORMS TO DEVELOP. NAM HAS A POCKET OF VERY UNSTABLE AIR BY
21Z (LIS AROUND -5) NEAR THE NEB/KS BORDER. WILL HAVE TO WATCH FOR
POSSIBLY SOME PULSE SEVERE STORMS THIS EVENING.

A COLD FRONT WILL MOVE ACROSS THE REGION TONIGHT THEN STALL IN THE
AREA. THIS WILL KEEP THE CHANCE FOR SHOWERS AND POSSIBLY A FEW
THUNDERSTORMS ALONG AND SOUTH OF THE BOUNDARY THROUGH THE HOLIDAY
WEEKEND. MODELS CONTINUED TO TREND COOLER AS MODELS HAVE A BETTER
HANDLE ON COLD AIR AVAILABLE.

THE END OF NEXT WEEK REMAINS DRY AND WARMER. WILL LIKELY SEE A DAY OR
TWO OF THUNDER HOWEVER THE MODELS STILL CAN NOT AGREE ON WHEN OR
WHERE...THUS WILL HOLD OFF BEFORE ADDING.
