The main hazards will be pockets of strong wind gusts and locally heavy rainfall. - Near-normal temperatures continue into Friday, with highs generally in the 80s. - A stretch of hot weather is expected this weekend into next week, with highs in the 90s and heat indices approaching 100 degrees. && .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. && .OAX WATCHES/WARNINGS/ADVISORIES...

.DISCUSSION...
Issued at 203 PM CDT Wed Jul 8 2026
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.
