  Eastern Dundy County in southwestern Nebraska...
  Hitchcock County in southwestern Nebraska...

* Until 1015 AM MDT /1115 AM CDT/.

* At 814 AM MDT /914 AM CDT/, Doppler radar indicated thunderstorms 
  producing heavy rain across the warned area. Between 1 and 2.5 
  inches of rain have fallen. Additional rainfall amounts of 1 to 2 
  inches are possible in the warned area. Flash flooding is ongoing 
  or expected to begin shortly.

  HAZARD...Flash flooding caused by thunderstorms.

  SOURCE...Radar.

  IMPACT...Flash flooding of small creeks and streams, urban
           areas, highways, streets and underpasses as well as
           other poor drainage and low-lying areas.

* Some locations that will experience flash flooding include...
  Trenton, Stratton and Max.

Additional heavy rain is moving in from the north with 1-2 inch per 
hour amounts possible.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood 
deaths occur in vehicles.

Be aware of your surroundings and do not drive on flooded roads.

In hilly terrain there are hundreds of low water crossings which are 
potentially dangerous in heavy rain. Do not attempt to cross flooded 
roads. Find an alternate route.

Please report observed flooding to local emergency services or law 
enforcement and request they pass this information to the National 
Weather Service when you can do so safely.

Area Forecast Discussion
National Weather Service Goodland KS
511 AM MDT Tue Jun 23 2026

.KEY MESSAGES...

- Sub-severe showers/storms and fog are forecast for most of
  the area this morning.

- Severe storms capable of producing up to 3 inch diameter hail,
  80 mph wind gusts and maybe a tornado or two are possible this
  afternoon and evening. The favored area is Eastern Colorado,
  but the entire area has a chance.

- Locations that received heavy rain during the past 24-48 hours
  are more prone to experience flash flooding, should additional
  heavy rain occur this afternoon.

- Severe weather chances continue through at least Thursday.

.SHORT TERM /THROUGH TONIGHT/...
Issued at 156 AM MDT Tue Jun 23 2026

Current observations show an upper low close to the US/Canada border
around MT/ND. Meanwhile, a large upper high is positioned
across much of the Southwestern and Southern United States. This
has been giving the area persistent northwest flow aloft. Near
the surface, there is a broad high pressure system across much
of the Midwest, with lower surface pressure over the Rockies.
This has kept the area in decent southerly/southeasterly flow
with speeds around 10-20 mph. This has also been transporting
low level moisture into the area with dewpoints generally in the
60s. The combination of these conditions has been supporting
the storms that we had earlier in the day. However, the constant
convection that has been in place the last few hours seems to
be draining the instability as storm intensity and coverage have
been lowering across the southern parts of the area. This
shifts concerns to northern parts of the area where additional
storms have been developing near Southwestern Nebraska. With the
help of the upper low axis swinging southeast, the storms might
be able to shift south into the area during the early morning
hours. If this is the case, showers and storms could linger in
Southwest Nebraska and Northwest Kansas through much of the day.
They would likely be sub-severe with little instability from
prior convection and increased low level cloud cover and fog
that is forecast to move in this morning with the moisture
advection. With the cloud cover and showers/storms, most of the
area should only warm into the 70s with 80s more likely for
counties along the Colorado border (away from the forecast
showers/storms).

This afternoon and evening, 2 different scenarios may play out. If
the showers, storms, and cloud cover linger in most of the area,
additional convection will be limited to whatever storms develop
along the higher terrain to the west of the area within the
continued upper level northwest flow. The other scenario is that we
get a break further east into the area that allows initial storms to
develop in counties along the Colorado border. In the second
scenario, we would not only have the initial storms, but the storms
moving in from the west as well. This presents a risk for
significant severe weather, mainly in Eastern Colorado and adjacent
counties. The forecast environment is forecast to have MUCAPE around
2000-3500 J/kg, 0-6km shear around 50-60 kts, and downshear vectors
around 50-60 kts. This would suggest and environment supportive of
very large hail up to 3 inches and wind damaging wind gusts likely
around 60-70 mph, but maybe up to 80 mph. With the high amounts of
shear, large hail may struggle to form as storms split and cluster.
Storm motions though around 15-25 mph may be slow enough to keep the
updraft together. The slow storms motions also pose a flooding
problem with these storms likely to be efficient rain makers. A
tornado or two may be possible as storms get themselves
together initially, but weak low level shear less than 10 kts
may hinder a bit too much. LCLs around 1000 meters also would
only marginally support tornadoes. Be careful though as a strong
tornado may occur with an isolated and well organized
supercell.

Late this evening and into tonight, the storms should cluster and
move east/southeast across the area. Depending on where the cluster
forms, the cluster could move across the entire area with wind as
the main threat at that point. Otherwise, those south of I-70
currently seemed to be favored. Once the cluster moves out of the
area, some linger showers/storms may be isolated across the area.
The main story then will be the cloud cover and fog moving back into
most of the area. In the absence of storms, the fog may be
dense at times. Temperatures should stay in the 60s, with maybe
some 50s for western portions of the area if the skies can
clear.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Issued at 126 PM MDT Mon Jun 22 2026

Chances for showers and thunderstorms continue Wednesday and
Thursday for the county warning area (CWA). Our region is forecast
to be in a mostly zonal flow with multiple shortwaves traversing
through the area. Severe weather is possible for the CWA with
Probability of Precipitation (PoPs) from 60-90% Wednesday and
Thursday. The environment is moderately unstable with around 1500-
2500 J/kg of CAPE and 20-40 knots of deep-layer shear. Supercells
with large hail and strong winds are possible withs storms that
develop. Flooding will also be a concern since the entire CWA has
received substantial rain recently.

Friday, we enter more of a weak ridging pattern with an incoming
trough west of the Rocky Mountains. Expect sunny skies and high
temperatures forecast in the 80s. Saturday through the end of the
forecast period continues to warm with high temperatures forecast in
the mid to high 90s for the CWA.

.AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/...
Issued at 505 AM MDT Tue Jun 23 2026

For KGLD... IFR conditions are forecast to start as ceilings
linger around 400-1000ft through about 18Z. Some fog with
visibility down to 1-2SM is also possible through 15-16Z. There
should be some improvement with the ceilings, likely to
1500-2000ft but with the possibility for VFR conditions from
18-02Z. Storms then become possible again after 22Z but mainly
around 02-06Z. Ceilings should lower again after that back to
500-1000ft with fog again. A lot of rinse and repeat.

For KMCK... IFR conditions with ceilings around 300-800ft
forecast through much of the period. Showers and storms are also
expected through much of the morning, clearing likely around
20Z. Ceilings may briefly get above 1000ft after 21Z, but should
lower again close to 03-06Z down to a few hundred feet. Showers
and storms may also move through after 06Z.

&&

.HYDROLOGY...
Issued at 209 PM MDT Mon Jun 22 2026

Through Thursday, we are looking at near daily chances of convection
as PWATs range around 0.9-1.75 inch. We are also expecting 0C level
to be around 15,000 feet AGL, leading to deep melting layers,
promoting efficient rainfall producing storms.

A Flood Watch has been issued for Dundy, Hitchcock, Cheyenne (KS),
Rawlins and Decatur counties until Tuesday morning. Over the past 48
hours, 3-6 inches of rain has fallen in the area, leading to
flooding. Additional storms are expected through this morning,
which may compound the flooding issue.

Tuesday, another round of storms is forecast to impact the Tri-State
area. Intensity and location are still up in the air, based on
today's storms and how much convection occurs early Tuesday morning.

Through at least Thursday, there are returning chances of
precipitation across the CWA.
