.DISCUSSION...
Issued at 1047 PM CDT Wed Jul 8 2026

Tonight through Friday...

A cluster of thunderstorms have developed along a front draped
across northeast Nebraska earlier this evening, supported by a
shortwave trough pushing across the northern Plains. Rather
limited deep-layer shear (around 20 kts) has kept the initial
storm development rather stationary along this boundary. Ample
instability (MLCAPE > 2500 J/kg) along with the sufficient shear
has brought pockets of strong to severe storms along this
cluster. Cold-pool development behind the line will lead to an
eventual southward push of this system into the overnight
period.

As the cold-pool helps force the storms into more of an upscale
cluster, isolated pockets of damaging wind gusts (pockets of 60
mph) will be one of the primary hazards over the next few
hours, aided by DCAPE of 1000-1200 J/kg. The severe weather
potential will gradually decay into the overnight period.
Locally heavy rainfall and flash flooding will remain another
concern. PWAT values near 1.80-2" (above the 90th percentile of
sounding climatology) and warm cloud depths of 4 km have brought
efficient rainfall processes, especially when coupled with the
longer residence time. Pockets of 3- 4.50 inches of rainfall
have been reported, with the highest totals in western Iowa. CAM
guidance continues to hint at a few scattered storms
redeveloping behind the main cluster overnight, though the
severe weather potential will be limited with these storms given
the increasing inhibition and decreasing shear.

Storms will push southward across the area overnight, clearing much
of the forecast area by 7 AM. Can`t rule out a few afternoon
storms redeveloping along the front in far southeast Nebraska
and southwest Iowa, though the better shear and instability
should stay just to our south. The lingering cloud cover and
slightly cooler air mass will bring afternoon highs in the low
to upper 80s. Similar temperatures are expected on Friday with
partly cloudy skies.

Saturday and Beyond...

This weekend into early next week, an amplifying mid- to upper-level
ridge is expected to build over the Front Range and gradually expand
eastward into the mid-Missouri Valley, leading to a warming trend
and relatively dry conditions. Highs on Saturday and Sunday will
take a step upward into the upper 80s to mid 90s. By Monday, most
locations are expected to reach the 90s a few spots in northeast
Nebraska expected to reach the triple digits. Overnight lows
will remain in the low 70s. Heat index values are expected to
reach the mid 90s to around 105 degrees daily. This hot pattern
with minimal precipitation chances will continue into the work
week.

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1210 AM CDT Thu Jul 9 2026

Showers and thunderstorms are now south of all three TAF sites.
Could see a isolated shower or two pop up overnight at KOMA or
KLNK, but at odds of under 20%, have left out of TAF for now.

Expect dry conditions to be most likely. KOFK is likely to see
LIFR conditions develop with fog and low cigs developing just
before sunrise. Otherwise expect VFR conditions to return by 10
AM.

.KEY MESSAGES...

- Scattered storms, a few severe, is expected this evening
  between mainly 6PM and 3AM. Hail up to the size of half
  dollars with wind gusts up to near 70MPH will be possible
  within the strongest storms.

- A few more scattered thunderstorms will be possible Thursday
  night for mainly a few western and southern portions of the
  area. Hail up to the size of golfballs with wind gusts up to
  near 60MPH may be possible.

- Though a small 10-30% storm chance returns Friday night, the
  rest of the 7-day forecast period will be favored to remain
  dry (10-40% chance of >0.1" of precipitation)

- Temperatures are expected to warm up over the weekend with at
  least a 4+ day streak of 90+ degree highs expected next week.

Tonight and Thursday...

A cold front, currently draped across northern Nebraska, will later
be expected to dip southward into much of south central Nebraska
this evening and later on into north central Kansas overnight. A few
storms will be expected to fire up along this front between mainly
6PM and 3AM as the front drifts southward. In addition, a cluster of
scattered storms (recently observed cumulus expanding across
northeast Colorado) will later be expected to roll in from off the
High Plains. These storms will possibly merge with activity
developing along the cold front, expanding the coverage of and
extending the time of lingering storms through the early morning
hours of Thursday.

The latest high-resolution ensemble forecast (HREF) guidance has
recently backed precipitation potential off by around 20% with a now
a more broad range forecast of 30-70% PoPs across the area for
tonight. Both the HRRR and NAMNEST models have come in a bit drier
(more scattered storm coverage) and continue to diverge on when and
where the best storm potential will come. The HRRR is more aggressive
with the earlier convection occurring along the cold front between
mainly 5PM and midnight. As result, the HRRR keeps the bulk of the
storms mainly north of I-80. The NAMNEST on the other hand is more
aggressive with the overnight convection rolling in from the high
plains. As result, it keeps a majority of the storms concentrated
south of I-80 and later in the night (2-8AM). In reality, the best
scenario tonight would likely be a combination of the two scenarios
where a few storms do initially form along the front and approach later
in the night from the west.

Given somewhat favorable conditions for thunderstorm maintenance
(1,500-2,5000J/kg of MUCAPE with 25-40kts of bulk shear), it is more
than reasonable to suspect that a few of these storms would be able
to take on some strong to severe characteristics. Though hail up to
the size of half dollars may be possible, the hail threat will
mainly fall within the initial storms firing up along the front. The
main severe threat tonight, however, will likely be the potential
for gusty winds up to near 70MPH, especially within storms racing in
from the west. The main uncertainty for severe weather this evening
will be if the storms firing along the front earlier in the
evening/night inhibit the severe potential for the later storms
coming in from the west. There is somewhat of a concern if the
convection along the front may undercut the severe threat overnight
to a degree, though the presence of a steady 20-30kts low-level jet
across north central Kansas may also play a small role.

In addition, the merging of these two storms clusters could create
an expansive area of heavy downpours. The possibility of 1" per hour
rainfall rates (1.5-1.8" PWAT values) mixed in with the potential
for multiple waves of thunderstorm activity could bring meaningful
precipitation amounts (up to 1-2+") to a handful of locations (10-
20% of the coverage area). The Weather Prediction Center has also
introduced a slight risk of excessive rainfall (15-40% chance of
rainfall amounts exceeding flash flood guidance within 25 miles of a
given point) to the full area. Given the overall decrease in
expected storm coverage, the flash flood potential has also overall
decreased some as well.

Beyond the precipitation chances tonight, the light to steady
surface winds (5-15MPH) will back from the southerly directions this
afternoon to an easterly one overnight. Cooler temperatures behind
the cold front will drop highs to the mid 80s to low 90s for
Thursday. Though the potential for severe weather returns Thursday
night (Marginal risk for western and southern portions of the area),
the overall storm coverage may likely be more isolated and
concentrated towards far west/south central Nebraska and north
central Kansas. A few storms, again racing out from off the High
Plains just after 10PM, will have to potential to clip a few
western/southern portions of the area. These storms, given the time
of night, will probably be on a downward trend, leading us to
speculate that the severe threat should mostly be more isolated
rather than widespread.


Friday into Next Week...

Though one final low-end chance for storms does lie Friday night (10-
30% chances), the main story Friday into next week will be the heat.
Highs Friday through the middle of next week will begin a gradual
climb from the mid to upper 80s to the low to mid 90s. This warm up
will come as a massive ridge is favored to form across much of the
central U.S. and intermountain west regions starting on Saturday.
This ridging pattern is in good agreement within the long-range
ensembles to stick around for most if not all of next week (>80%
confidence). The presence of this massive ridge should bring warm,
subsiding air to the region that will work to thwart off most of the
precipitation potential next week. (The LREF {Long Range Ensemble
Forecast} only shows a 10-40% chance for at least 0.1" of
precipitation through the week).

The main uncertainty at this time will be for how substantial the
warmup will become (will highs next week peak in the upper 90s or
low 100s?). What does look almost certain will be the presence of a
streak of 90+ degree days. The only forecast element that could keep
such a streak from taking place would be from a rogue daytime
thunderstorm or excessive cloud cover that manages to peak in (not
very likely to occur underneath such pattern).

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1227 AM CDT Thu Jul 9 2026

For KGRI/KEAR Airports:

MVFR Ceilings possible ~10-15z, otherwise VFR conditions
expected during TAF period. SCT-BKN stratus will build over the
area through sunrise. Some of this stratus may fall to MVFR,
though the duration at KGRI/KEAR is uncertain. Due to the
scattered nature of MVFR status, a TEMPO group was used to
indicate this potential. Stratus clears by the mid-late morning
hours, first at KEAR then KGRI, with high level clouds possible
through the end of the TAF period. Light and variable winds
become northerly, shifting the northeast Thursday morning, then
to the east Thursday evening.
