Did it verify
Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood 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

.KEY MESSAGES...
- Scattered storms through the overnight with primary a heavy
rain and flash flood threat, but a few severe storms possible
with large hail and damaging winds.
- A cluster of storms is forecast to move into the area Saturday
evening from Colorado with damaging winds the primary hazard.

.UPDATE...
Issued at 805 PM MDT Fri Jul 3 2026
Issued a Flash Flood Watch for southwest Nebraska through the
overnight hours. This area received 2 to 5 inches of rain last
night and soils are saturated. Thunderstorms have developed in
northeast Colorado and are moving eastward. The low level jet
will become active once again similar to the previous couple of
nights and maintain the convection well into the overnight
hours. Some southerly motion may develop with time, but that is
uncertain. 21z RFS shows 2-4 inches possible in Nebraska, while
the 00z HRRR has the heavy rainfall further south. However,
given the antecedent rainfall think the threat of flooding is
enhanced for southwest Nebraska should storms move over that
area.
&&
.SHORT TERM /THROUGH SUNDAY NIGHT/...
Issued at 1212 AM MDT Sat Jul 4 2026
In the near term...thunderstorms are expected to increase in
coverage as they move out of Colorado the next few hours and
continue through the overnight as the low level jet strengthens.
Locally heavy rainfall will be the main concern, but may also
see a few embedded stronger storms with a marginal wind and hail
threat. Storms should be exiting the area to the east between
11-13z.
For the rest of today...upper ridge over west Texas and New
Mexico well start to build into the southern Rockies, turning
the flow over the central plains from zonal to slightly
northwest. Another embedded wave will move through this
afternoon and evening. CAMs show convection initiating along
the Front Range and Cheyenne Ridge 21-22z and moving southeast,
reaching the Colorado and Kansas border area 00-03z. However,
with rapidly declining instability, and lack of a low level jet,
storms are forecast to decay rather quickly. Remnant outflows
appear to be the main severe threat through the early evening
into northwest Kansas, ending by 06z at the latest, but probably
closer to 03z. Given the lack of a low level jet, not expecting
any overnight convection.
On Sunday...upper ridge continues to build northward into
Colorado, with a northerly flow around it over the central
plains. Given the lack of forcing in proximity to the ridge,
convection appears unlikely.
&&
.LONG TERM /MONDAY THROUGH FRIDAY/...
Issued at 139 PM MDT Fri Jul 3 2026
Starting with the upper pattern, there is a ridge that begins to
move in over the Dakotas and Canada. This ridge will begin to stall
out and remain stationary for the majority of the period. Along with
the ridge, there are two lows both sitting off of the northern west
and northern east coast. With this pattern our flow for the CWA will
mainly be weak zonal and will see some small embedded shortwave
troughs throughout the week. These shortwaves will likely bring some
higher precipitation chances for the area.
Sunday through Friday all look very similar with high temperatures
in the low 80s to upper 90s. Beginning Wednesday there is slight
increase with temperatures reaching near 100 degrees. The
probability of exceeding 100 degrees for Wednesday through
Friday is 5-10% for mainly areas south of I-70. Except for
Friday, areas west of KS Hwy 27 along with south of I-70 will
see 5-15% of exceeding 100 degrees. Moving to the winds they
mainly remain out of the south-southeast. Gusts look to remain
around 25-35 mph. RH values remain above 20% for the majority
of the period as well.
As for precipitation/storm chances, PoPs are showing there being 15-
30% chance for the majority of the CWA for this period. Moving to
storm potential, Guidance is showing there being around 1000-2000
J/kg of SFC-CAPE. Looking at Bulk Shear there is 25-40 kts.
NCAR AI Convective Hazard Forecast products is showing there
being around a 5-15% of severe hazards for at least one county
in the CWA. Given the shortwaves that move through the area
along with the storm ingredients there could be the potential of
storms for the period.
&&
.AVIATION /06Z TAFS THROUGH 06Z SUNDAY/...
Issued at 1138 PM MDT Fri Jul 3 2026
Scattered thunderstorms will develop across the area overnight
with around a 30% probability of impacting either terminal with
brief reductions in ceilings and visibility in rain, as well as
gusty winds. The thunderstorms should exit the area by around
12z. Otherwise, VFR expected to prevail through Saturday
afternoon. Next round of storms will move out of Colorado in the
late afternoon or early Saturday evening, with a low probability
of impacting KGLD with gusty winds from associated outflow.
