What was reported inside it
| Time | Report | Where | Remark |
|---|---|---|---|
| Jun 17, 7:05 PM CDT | Hail 1.75 | Orleans, NE |
NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in.
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, 11.5 hours before the alert went out and 144 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.

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Jun 17, 2:06 PM CDT, 4 hours 23 minutes before
SOUTH CENTRAL NEBRASKA/NORTH CENTRAL KANSAS FORECAST DISCUSSION NATIONAL WEATHER SERVICE HASTINGS NE 206 PM CDT MON JUN 17 2002 ...MAIN FORECAST CHALLENGE IS FOCUSING ON PERIODS WITH BETTER CHANCES FOR THUNDERSTORMS... NEARLY IMPOSSIBLE TO TOTALLY DISCOUNT CONVECTION ESPECIALLY IN THE NIGHT THROUGH EARLY NEXT WEEK...BUT THAT/S NORMALLY THE CASE IN JUNE. TONIGHT LOOKS LIKE IT COULD BE A REPEAT OF LAST NIGHT. SURFACE TROUGH ON A HON-LBF LINE COUPLED WITH S/W INDICATED ON WV SATELLITE OVER NEB PANHANDLE MAY BE ENOUGH TO FIRE THUNDERSTORMS LATE THIS AFTERNOON. ANY THAT FORM WOULD LIKELY BECOME MORE WIDESPREAD AS THEY ENCOUNTER SOMEWHAT DEEPER MOISTURE AND DEVELOPING LOW LEVEL JET AS THEY MOVE EAST. APPEARS A LULL IN THE ACTION TUESDAY INTO WEDNESDAY AS UPPER RIDGE AND WARMER MID LEVEL TEMPERATURES BUILD IN. WEDNESDAY NIGHT AND SATURDAY NIGHT APPEAR TO OFFER THE GREATEST CHANCE FOR RAIN/THUNDERSTORMS ACROSS GID CWA. RIDGE WEAKENS AND DRIFTS EAST AS WIDE WESTERN STATES WAVE APPROACHES WEDNESDAY NIGHT. NEXT WAVE TAKES A NORTHERN TRAJECTORY BUT CHASES ANOTHER FRONT ACROSS NEBRASKA LATE SATURDAY. WILL CONTINUE CHANCE FOR RAIN/STORMS SUNDAY AND MONDAY WITH WEAK SURFACE FRONT AND EXPECTED SHORT WAVES ROUNDING THE TOP OF SOUTHWEST UPPER RIDGE. .GID...NONE. SCHURR
