The radar

The North Platte radar (KLNX), 179 km from the middle of the area, began a volume at 00:11 UTC, the scan nearest the moment this went out.

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

Aberdeen, SD (KABR), launched 00:00Z, 0.2 hours before the alert went out and 229 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 26, 6:31 PM CDT, 38 minutes before

Area Forecast Discussion
National Weather Service North Platte NE
631 PM CDT Sun May 26 2019

.SHORT TERM...(This evening through Monday night)
Issued at 352 PM CDT Sun May 26 2019

Strong to severe thunderstorms will be possible tonight, and
again Monday afternoon and evening. Deep southwesterly flow aloft
is in place across the region this afternoon and will remain in
place through Monday night.

Surface low pressure in eastern Colorado will track into southern
Nebraska tonight. A strong disturbance in the TX panhandle and
nern NM will move quickly northeast this evening and produce
clusters of thunderstorms, initially in southwest Nebraska to
spread northeast overnight. Severe storms are possible south of
highway 2, with strong storms to the north. Large hail and
damaging winds will be possible. The focus for heavy rainfall is
expected to be east of Imperial through Stapleton and Bassett.
Rainfall amounts of a half inch could be widespread with locally
an inch and a half overnight. Less coverage across western areas.

On Monday, a surface front will strengthen, generally near Highway
2. Shower or thunderstorm activity will be fairly isolated in the
morning, then new development should quickly occur by 4 pm cdt.
Nearly all of western Nebraska is in a slight risk for severe
thunderstorms except for far southwestern areas, where strong
storms are still possible. Due to the existence of a warm front
and strong shear aloft, an isolated tornado is possible in
addition to large hail and damaging winds late afternoon into
Monday evening. Heaviest rainfall amounts to be across north
central Nebraska up to a half inch with locally an inch.

.LONG TERM...(Tuesday through Sunday)
Issued at 352 PM CDT Sun May 26 2019

On Tuesday, the upper low will begin to move into the panhandle
and southwest Nebraska in the afternoon. The risk for severe
weather should shift east to still include areas east of Burwell
through Bassett. Rainfall amounts will increase significantly by
Tuesday afternoon across north central Nebraska. Areas north and
west of the upper low center can expect the heaviest rainfall into
Tuesday night, which again includes north central Nebraska. Have
extended the Flood Watch through 12Z Wednesday to include rainfall
Tuesday night.

Shower chances linger Wednesday as the upper low lifts slowly
eastward. Highs limited to the lower 60s most areas. Lesser
chances for showers or thunderstorms Thursday through Sunday. Yet,
synoptically the flow will remain fairly zonal and a moist
atmosphere will remain in place. Highs look to range in the 70s.

&&

.AVIATION...(For the 00Z TAFS through 00Z Monday evening)
Issued at 631 PM CDT Sun May 26 2019

Showers and thunderstorms will become more widespread this evening
and tonight across western Nebraska while MVFR cigs continue.
Gusty erratic winds, hail, and torrential rainfall are the primary
threats with these storms. Brief rapid drops in visby are likely
with any storm, along with lower cigs. The consistent rain tapers
off by 12z for most of western Neb, but cigs drop into IFR
category. Easterly surface winds strengthen heading into Monday
afternoon with gusts exceeding 20 kts.

&&

.HYDROLOGY...
Issued at 352 PM CDT Sun May 26 2019

River levels continue to fall on the Elkhorn river at Atkinson
and Ewing. Atkinson gauge remains above minor flood stage with the
latest reading at 7.90 ft. A flood warning remains in effect for
west central Holt county through early Sunday evening and may
need to be extended. Elsewhere, a Flood Warning remains in effect
in northern Brown County though officials reported water levels
have decreased there. A Flood Advisory remains in effect for the
Cedar river near Erickson as water levels remained high with
additional heavy rainfall possible tonight.

Otherwise, rainfall totals were increased slightly with amounts
near 2 inches across parts of far northern NE. Storms and
significant rainfall totals remain possible tonight through
Tuesday night with the Flood Watch extended 12 hours until 12Z
Wednesday. The heaviest widespread rain is expected to occur
Sunday night, Monday night, Tuesday afternoon and Tuesday night.
Overall, total rainfall amounts of 1 to 2 inches are forecast
across northern NEB and the northern Sandhills with locally higher
amounts possible.

north central Nebraska.

.DAY ONE...TONIGHT.

Flood warnings and advisories remain in effect across portions of
north central Nebraska, including the Elkhorn and Cedar Rivers.
Please refer to the latest flood products for details.

Isolated to scattered strong/severe thunderstorms are possible
this evening and into the overnight for all of western and north
central Nebraska. The main threats will be large hail, damaging
winds, and torrential rainfall. The area of greatest concern will
be across portions of southwest Nebraska into south central
Nebraska, generally along and south of Interstate 80. Moderate to
heavy rainfall will be possible this evening and overnight hours
with rainfall amounts between a half inch to three quarters of an
inch across portions of central Nebraska.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.

Isolated to scattered severe thunderstorms will be possible late
Monday afternoon and into Monday night. The area of greatest
concern is across the Sandhills and northern Nebraska. The main
threats will be large hail, damaging wind gusts, torrential
rainfall and isolated tornadoes.

Storms and significant rainfall totals are possible through
Tuesday evening. The heaviest widespread rain is expected to
occur Monday night and Tuesday. Total rainfall amounts between 1
to 2 inches are in the forecast. The additional rainfall will
increase the potential for flooding due to already saturated
soils, increased runoff, and high water tables. A Flood Watch goes
into effect Sunday evening through Tuesday evening for the
northern Sandhills and northern Nebraska.

.SPOTTER INFORMATION STATEMENT...

Spotter are encouraged to report hail, wind, and flooding to the
National Weather Service over the next several days.
