.DISCUSSION...
Issued at 318 PM CDT Mon Jun 16 2025

Today and tonight...

An upper ridge extends from northern Mexico up towards Kansas and
southern Nebraska. A shortwave trough in the upper flow will move
over the area this afternoon into tonight. A cold front has began to
push into western and northern portions of Nebraska this afternoon.
Atmospheric lift is being enhanced along the front and shortwave
trough. Dewpoint temperatures across south central and central
Nebraska and north central Kansas are in the 60s. A surface trough
will be present ahead of the cold front with winds mostly out of the
south. Lift and instability will be enhanced along this surface
trough. High to very high surface CAPE values will be across the
area with values increasing to the northwest along the surface
trough. Mid-level lapse rates and wind shear will also be fairly
high. Thunderstorms are expected to develop, possibly as early as
around 4 PM and as late as 9 PM, and will continue across the area
into the overnight hours. Severe storms are expected given the
previously mentioned conditions. Damaging winds and large hail will
be the main threats although there is a slight chance (around 20%)
of an isolated tornado or two.

There is some uncertainty in the models as to when convection will
start to develop and possibly where it will develop first. One hi-
res model shows a line of storms developing around 5 PM from Greeley
County southwest to Dawson County and moving southeastward through
the evening. This models shows most, if not all, of the storms out
of the area by 2 AM. Another hi-res model shows storms just
beginning to enter Valley County around 9 PM with other storms
moving in from the northwest through the overnight hours. This model
shows storms still ongoing during the morning hours. High
temperatures today will range from the lower to upper 90s. Low
temperatures tonight will range from the upper 50s to mid/upper 60s.

Tuesday and Tuesday night...

An upper trough will begin moving over Nebraska and Kansas on
Tuesday. Showers and storms may still be ongoing, especially across
north central Kansas, Tuesday morning. There is also some model
uncertainty in regards to timing and placement of convection on
Tuesday. Some models start storm development in the afternoon while
others hold off until evening with a line of storms that sweeps in
from the west. Tend to think that any storm development in the
afternoon will be weaker and the main storms will impact the area
during the evening and possibly overnight hours. One hi-res model
shows storms developing across the area during the early evening
hours then a line of storms moving in from the west through the rest
of the evening into the overnight hours. Strong to severe storms are
expected on Tuesday, especially during the late afternoon through
evening hours. The area of greatest threat for severe storms on
Tuesday will be north central Kansas and along the Nebraska-Kansas
border while instability will be highest. Large hail and damaging
winds will be the main threats with these storms although an
isolated tornado or two is possible. High temperatures Tuesday will
be in the mid 70s to mid 80s and low temperatures Tuesday night will
be in the mid 50s to mid 60s.

Wednesday through Sunday...

Some lingering showers and thunderstorms may remain across eastern
portions of the area on Wednesday (15% to 25% chance); otherwise,
Wednesday is expected to be mostly dry. Winds will be mostly out of
the north across south central and central Nebraska and north
central Kansas on Wednesday with temperatures warming up into the
upper 70s to mid 80s. Winds will switch to to south to southwest
Wednesday night with low temperatures in the mid 50s to low 60s. An
upper ridge will extend northward into Kansas and Nebraska on
Thursday with winds across the area strengthening out of the south
to southwest. Mostly sunny skies will be present with temperatures
warming up into the low to mid/upper 90s. Low temperatures Thursday
night will be in the mid 60s to low 70s. The upper ridge will extend
from the Gulf Coast northward over Nebraska and Iowa on Friday. The
ridge will become more amplified on Saturday extending towards the
Great Lakes. Friday and Saturday are expected to be the hottest
days so far this season with highs in the mid 90s to around 105
degrees. Heat index values across the whole area will mainly be
in the triple digits ranging from 100 to around 105. The upper
ridge shifts a little further east on Sunday with temperatures
across the area cooling slightly.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 655 PM CDT Mon Jun 16 2025

For KGRI/KEAR Airports:

Significant weather: Strong-severe thunderstorms with high wind
gusts possible 03-06Z at both terminals.

Tonight: Rather complex scenario possible late this everning
into the overnight. Current expectation is for clusters of
thunderstorms to congeal NW of the terminals next few hours,
then roll E/SE towards the Tri-Cities in the 03-06Z time frame.
Thunderstorms will likely be on the strong side, and could be
severe, with wind gusts of 45-55kt the primary concern -
particularly along the leading edge. Behind this cluster after
06Z, it's highly uncertain what the sensible weather will be -
both in terms of observed weather/CIGs AND wind speed/direction.
Some models depict scattered convection lingering over or nearby
through around dawn, whereas other guidance is mainly dry with a
variable or E/NE wind ~10kt and VFR conditions. Will maintain
some PROB30 groups for -TSRA in the 06-12Z time frame, with
potentially the strongest activity capable of brief dips to MVFR
CIGs/VSBYs. Overall confidence is medium through 06Z, then LOW.

Tuesday: Uncertainties linger into Tuesday as sensible weather
conditions will depend greatly upon how things play out tonight.
There's at least a chance (20-40%) that some MVFR stratus could
unfold at some point in the morning and continue into early
aftn...but haven't gone this low just yet considering the
uncertainty. Otherwise, expect at least SCT to BKN mid to high
clouds much of the day. Conceptually, would expect a break in
the rain/storms for a good chunk of the AM- early aftn, before
perhaps another round develops/moves in for the late aftn and
evening. Timing/coverage/placement with this is also very
uncertain, so only PROB30 for now. It's possible any convection
could hold off until closer to/after sunset Tue eve. Winds may
be quite variable in the AM, but expect mainly NE-E flow to
develop by midday. Confidence: VERY LOW.

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

.DAY ONE...Tonight.

There is a slight to enhanced risk of severe thunderstorms across
the whole outlook area this evening into tonight. Thunderstorms
are expected to develop or move into the area along a line from
roughly Gothenburg to Fullerton between 8PM and 10PM. The main
hazards with these initial storms will be wind gusts up to 70 MPH
and golf ball to tennis ball size hail. There is a low threat for
an isolated tornado or two. By 10PM, multiple clusters of storms
are forecast to merge over south central Nebraska, then move
south and southeast across the remainder of the area. The main
hazard overnight will be wind gusts up to 70 MPH, and perhaps
quarter size hail. Locally heavy rain of 2 to 2.5 inches will be
possible, but widespread flooding is not expected.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.

There is a marginal to slight risk of severe thunderstorms
Tuesday into Tuesday night across the outlook area with the
highest threat across north central Kansas and along the Nebraska-
Kansas border. While thunderstorms may develop during the morning
and afternoon hours, the greatest severe potential will be from
around 6 PM to 2 AM. The main hazards with these storms will be
damaging winds and large hail. There is a low threat for an
isolated tornado or two.

On both Friday and Saturday afternoons, heat index values are
forecast to reach as high as 100 to around 105 degrees across
most of our forecast area.

.SPOTTER INFORMATION STATEMENT...Spotters are encouraged to
report any thunderstorm-related severe
weather or damage that might occur this evening and overnight,
including wind gusts around 60 MPH or higher, and hail 1 inch
diameter or larger.
