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.

- Chance of thunderstorms late this evening into the overnight,

- Brief warm-up Friday, cooler into the weekend with some

.SHORT TERM /THROUGH FRIDAY/...
Issued at 334 PM CDT Wed Jun 10 2026

The main concern in the short term is the fire weather
concern this afternoon and storm development late this evening into
the overnight. Across western Nebraska drier conditions will exist,
generally west of HWY 61, where dew points are in the 30s leading to
min RH around 10 to 15 percent. Winds will also remain breezy out of
the west around 15 to 25 mph with gusts up to 40 mph. Looking at
local observations from rainfall yesterday into the overnight,
although there were scattered storms across western Nebraska, the
rainfall amounts were low. Given the lower rainfall amounts across
western Nebraska, the low RH and the gusty winds this afternoon, a
decision was made to issue a Red Flag warning for this afternoon
into the early evening for fire weather zone 204.

As far as thunderstorm development late this evening into the
overnight, confidence remains low in just how much convection will
develop this evening. The 18z sounding showed marginal elevated CAPE
with drier air at the sfc, decreasing confidence in evening
development. Still do expect a LLJ to develop tonight and
interact with a frontal boundary, however the frontal boundary
may push further south of the area than expected, lowering
confidence in storm development across the CWA. However there
still remains some potential for some elevated development as
the instability increases. Although think the threat for
strong/severe potential will be relatively low, still can't rule
out a potential for a supercell to develop, but latest trends
have continued pushing that threat eastward, with just a
marginal threat for elevated thunderstorms to develop. If a
thunderstorms were to develop with the strengthening LLJ given
the latest sounding, the dry air near the sfc and the weak
elevated CAPE will likely confine the hazard to mainly a strong
wind potential, although there is a remote chance of hail as a
secondary threat.

For Thursday, much cooler temperatures expected with CAA behind the
cold front. Drier conditions are also expected, although there could
be some early morning thunderstorms, beyond the morning hours a
mostly dry day is expected with dew points in the 30s to 40s. High
temperatures will be cooler with highs only in the low to mid 70s
across much of the forecast area. Winds will remain gusty behind
the cold front out of the northwest around 15 to 25 mph
sustained with gusts of 35 mph or greater possible, with the
strongest winds across the western and northwest Sandhills.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Issued at 334 PM CDT Wed Jun 10 2026

A warm front is expected to move in across western Nebraska on
Friday with WAA greatest across western Nebraska. Will see
temperatures in the 90s across western Nebraska and in the upper
80s across north central Nebraska. Could see the potential for
near critical to potentially critical fire weather conditions
across western Nebraska. Dew points decrease across western
Nebraska through the afternoon and min RH will drop around 10 to
15 percent in the afternoon. Winds will be out of the southwest
around 20 to 25 mph sustained and could see gusts up to 40 to 45
mph. Will see a couple disturbances this weekend move across
the area and could see precipitation chances late Saturday into
Sunday.

&&

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1243 AM CDT Thu Jun 11 2026

VFR conditions will prevail across all of western and north
central today. These will be a few scattered TSTMS early this
morning prior to sunrise. A cold front will cross the area with
gusty northwest wind developing around sunrise and continuing
though the day. Winds of 20-25 kts with higher gusts are
anticipated. Winds quickly diminish this evening and become
light.

257 PM CDT Wed Jun 10 2026 /157 PM MDT Wed Jun 10 2026/

This Hazardous Weather Outlook is for portions of western and north
central Nebraska.

.DAY ONE...This afternoon and tonight.

Critical fire weather conditions are expected today across western
Nebraska. A Red Flag Warning remains in effect across western
Nebraska until 8 PM MDT today.

Scattered thunderstorms are expected to develop later this evening
and overnight tonight. A couple of the storms could produce gusty
winds, with a small threat for hail, generally for areas east and
northeast of North Platte across central Nebraska.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.

Elevated to near-critical fire weather conditions are expected for
mainly western Nebraska Thursday and Friday. Recent rainfall across
north central into portions of the eastern Sandhills has helped with
the green-up, thus near critical to critical fire weather conditions
will be localized to areas that haven't received beneficial rain the
last dew days.
