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

N. Platte/Lee Bi, NE (KLBF), launched 00:00Z, 11.2 hours before the alert went out and 76 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.

.DISCUSSION...

FORECAST CHALLENGE TODAY WILL BE SEVERE THREAT. AT 08Z RADAR
CONTINUED TO SHOW TWO SEVERE STORMS TO THE NORTH THAT WILL
CONTINUE TO MOVE SOUTHEAST NEAR 40 MPH.CLUSTER OF STORMS ARE
MOVING EAST WITH HAIL THE PRIMARY THREAT WITH WINDS REMAINING A

ONGOING CONVECTION WILL MOVE EAST BY MID MORNING WITH THE FORECAST
CHALLENGE TODAY TO BE SEVERE STORMS AGAIN BY LATE AFTERNOON. ANOTHER
ROUND OF SEVERE STORMS ANTICIPATED AS PEAK HEATING OF THE DAY TO
LEAD TO EXTREME INSTABILITY IN THE AFTERNOON AS WARM FRONT LIFTS
NORTH TO THE NEBRASKA KANSAS BORDER. MODELS ARE SIMILAR WITH UPPER
RIDGE TO BREAK DOWN OVER THE PLAINS WITH HEIGHTS FALLING THIS
AFTERNOON. H25 ANTICYCLONICALLY CURVED JET CROSSES WITH JET MAX TO
ENHANCE LIFT IN THE WEST FOR STORMS TO FIRE TO THE WEST THAT WILL
MOVE EAST TONIGHT THROUGH MIDNIGHT CDT. EXISTING BOUNDARIES FROM
OVERNIGHT CONVECTION MAY ALSO SERVE AS FOCUS. THE H85 JET
STRENGTHENS OVERNIGHT WITH BETTER MOISTURE ADVECTION TO START PUSHING
EAST ALTHOUGH ADDITIONAL STORMS LIKELY INTO TUESDAY AS SURFACE LOW
DEEPENS OVER EASTERN KANSAS AND MOVES EAST. EXTENSIVE CLOUD
COVERAGE EXPECTED THAT WILL HOLD TEMPERATURES DOWN FOR A FEW
DEGREES YET READINGS INTO THE 70S TO MIDDLE 80S SOUTHWEST.

TUESDAY THE LOW PRESSURE SYSTEM MOVES EAST ACROSS KANSAS BUT WITH
THE PROGRESSIVE PATTERN THE THREAT FOR STORMS WILL EXIST EACH
DAY THROUGH FRIDAY.

TO THE NORTH WILL INCREASE FOR MVFR CONDITIONS INTO THE
AFTERNOON. BY AFTERNOON CLOUDS WILL BEGIN TO LIFT FOR VFR
CONDITIONS UNTIL 03/00Z WHEN STORMS ARE EXPECTED TO BE ONGOING
THAT WILL DROP CEILING AND VISIBILITIES DOWN TO MVFR CONDITIONS
DUE TO CONVECTION.
