.DISCUSSION...
Issued at 227 PM CDT Sat Sep 12 2026

Despite relatively cool and stable air at the surface, scattered
storms have continued to develop over central Nebraska. These
storms, fueled by decent elevated instability (1000-2000 J/kg
MUCAPE), have resulted in several strong to marginally severe
updrafts (including 1.25" hail in Holdrege around noon). Near-
term modeling has struggled to handle the subtle forcing
responsible for these storms, but the expectation is that
coverage will diminish this afternoon, with a potential uptick
again this evening over southeast parts of the area. Most
activity will likely remain non-severe, but a few strong to
marginally severe storms remain possible. Given the elevated
nature of the storms, hail will be the primary threat.

Additional showers/storms may develop late tonight into Sunday
morning, aided by warm air advection in the low levels, although
this is unlikely to become severe given the timing. The highest
coverage will gradually shift eastward through the morning
hours, with dry conditions returning for Sunday afternoon.
Lingering cloud cover will keep temperatures on the cooler side
for Sunday (highs only in the 70s for most).

Monday is the main day to watch for severe weather. Ahead of an
advancing cold front, we should see substantial warming with
many areas returning to the 90s. This, of course, also yields a
very unstable environment as the cold front moves into the area
during the afternoon and evening. The latest Day 3 SPC outlook
has upgraded part of the area to a "Slight Risk" (Level 2 of 5),
which seems appropriate.

After this front moves through, the rest of next week looks
relatively wet and cooler than normal. Continued southwesterly
flow aloft, combined with a stalled front just to our south will
result in daily chances for rain and thunderstorms. Details
remain uncertain, but ML severe guidance would suggest that the
severe threat remains fairly low. Models vary on exactly "how
wet" next week will be, but all of the global ensembles (EPS,
GEFS, CMCE) along with their AI counterparts favor above-normal
rainfall totals over the next 7 days.

.AVIATION /00Z TAFS THROUGH 00Z SUNDAY/...
Issued at 603 PM CDT Sat Sep 12 2026

For KGRI/KEAR Airports:

MVFR ceilings expected sunrise-mid afternoon hours on Sunday.
SCT low and high level clouds are possible through midnight but
skies are not expected to become MVFR before midnight. After
midnight, a cluster of scattered showers is possible through the
mid-morning hours (indicated with PROB30 groups). Within this
cluster of showers, MVFR stratus is possible at times, becoming
prevailing MVFR around sunrise. The MVFR stratus will linger
into the afternoon hours, before gradually rising to VFR by the
mid-late afternoon. There`s some uncertainty on how long MVFR
CIGS last, and opted to go with a longer lasting scenario. Light
easterly winds increase during the afternoon hours on Sunday.
