.DISCUSSION...
Issued at 135 PM CDT Wed Jul 8 2026

Showers and a few weak thunderstorms have fired up along a cold
front and are currently moving across northeastern
Nebraska/northwestern Iowa. This activity is expected to continue
over the next few hours. Heading into the evening, models are
showing a line of thunderstorms developing along the cold front.
MLCAPE values of 2500+ are expected along with DCAPE values of
1000+, particularly for areas extending from along and south of a
line from Fremont to Utica. A few single thunderstorms will
eventually congeal into a line as it moves southeast. Strong to
severe thunderstorms are expected with wind, hail, and localized
flooding be the main concerns. Precipitable water values are in the
1.4-1.7" range, so any storms that are able to get going could be
efficient rain makers. Right now, the best chance for strong storms
will be after 7pm. Thunderstorm chances will continue overnight.

A few showers/storms may linger into the morning Thursday, before
tapering off by early afternoon. Enjoy the cooler temperatures as
highs reach the mid-80s for most locations. Afternoon high
temperatures will be dependent on how soon the rain and clouds clear
out. A quicker exit would allow us to warm slightly higher than
forecasted temperatures, while a delayed exit would result in cooler
temps. Despite the slightly cooler temperatures, dewpoints will be
in the 60s and 70s, so it will feel pretty muggy. A shortwave trough
moves across the region Thursday afternoon/evening, bringing a
chance for a few additional showers and storms.

Friday will bring more relief from the heat as highs climb into the
low to mid-80s. However, dewpoints will once again be in the 60s and
70s, so it will feel pretty muggy. Another shortwave trough slides
across eastern Nebraska Friday afternoon, bringing another chance
for showers and thunderstorms.

Saturday through the rest of the extended forecast: An upper ridge
builds over the region with surface high pressure centered over Iowa
and Illinois. While we will have a break from the thunderstorms, the
heat is expected to return. The CPC is showing that there is a good
chance of above normal temperatures occurring across the Midwest and
Great Plains in the 6-10 and 8-14 day outlooks. Sunday highs will
reach into the 80s and low 90s. Heading into the start of next week,
widespread 90s will return. Lows will be in the low 70s several
nights.

.AVIATION /00Z TAFS THROUGH 00Z FRIDAY/...
Issued at 522 PM CDT Wed Jul 8 2026

Thunderstorm development is underway along a front draped across
northeast Nebraska this evening. Storms will quickly grow into
a larger cluster that slowly pushes southward into the overnight
period. Confidence is high (80%) that each terminal will see
thunderstorms tonight, with some amendments/refinements likely
needed in exact timing. Patchy MVFR to IFR conditions are
possible under any heavier thunderstorms. Strong to severe
storms will also be possible, with pockets of damaging wind
gusts (up to 50 kts) and hail (up to 1.50 inches). Severe
weather potential will gradually diminish into the overnight
period.

Storms will clear from north to south during the early morning
hours Thursday, with patchy MVFR ceilings possible into the
morning hours behind the clearing showers. Winds will remain
out of the south ahead of the front, quickly shifting to
northerly behind the front. Winds will remain at 8-12 kts,
besides when augmented by thunderstorm gusts.
