.UPDATE...
Issued at 131 AM CDT Sun Sep 20 2026

Scattered showers/storms will move into west/southwestern portions
of the area early this morning. Aloft a trough is centered over the
Rockies with weakly zonal-northwesterly flow over the eastern U.S.
Showers/storms will lift east/northeast across the area during the
day, with rain coming to an end over NE portions of the area by the
late afternoon hours. Widespread stratus and rain will help to keep
the day seasonably cool. Highs in the 60s are expected across most
of the area, with temperatures in the low 70s across southwestern
portions of the area where some sunshine is possible.

A weakening cluster of storms that develops over western NE/Eastern
CO may sneak into far western portions of the area this evening
before dissipating. Given the anticipated weakening trend, storms
are expected to fall below strong/severe strength by the time they
reach western portions of the area. Overnight, scattered showers
along the NE/SD border may sink into far northern portions of the
area (along/N of Highway 92) though any accumulations would be
light.

Troughing persists over the area on Monday with low stratus locked
in place over central/northern portions of the area. Under the
stratus highs will be confined to the 60s.
Southern/southwestern portions of the area could see more
sunshine, allowing temperatures to climb into the mid 70s. A few
showers may linger across the area throughout the day, but most
areas look to remain dry. Otherwise seasonable-seasonably cool
weather persists throughout the school week with highs generally
in the 60s and 70s. Passing disturbances will bring off and on
chances for showers/storms through the end of the forecast
period with the most widespread chances Wednesday night-
Thursday.

.DISCUSSION...
Issued at 236 PM CDT Sat Sep 19 2026

A line of showers and thunderstorms has developed across western
portions of the area this afternoon. These showers and
thunderstorms are expected to rapidly weaken and dissipate as
they track eastward through early evening hours with a more
robust line of showers and thunderstorms eventually developing
to our southeast later this afternoon along yesterdays cold
front. In general, the 18Z HRRR seems to have caught on to this
initial line of showers and thunderstorms stretching from Dawson
in to Furnas counties, and largely updated the pops for the next
few hours to reflect this.

Later tonight, expect a cluster of showers and thunderstorms
developing across the Rockies to move into the plains, bringing
a better shot for some more widespread shower and thunderstorm
activity overnight. Given limited instability and shear, this
cluster should be weakening as it crosses the local area, but
cannot completely rule out a stronger thunderstorm across our
west initially, especially across areas west of Highway 183.
Further east, thunderstorm coverage will diminish and only light
rainfall accumulations are anticipated by Sunday morning.

After a seasonable day this afternoon, expect temperatures to be
on the cooler side of climo Sunday afternoon, which will mark
the start of a prolonged period of seasonal to seasonably cool
temperatures across the region. At the same time, the flow aloft
will fluctuate between westerly and southwesterly, which should
allow multiple upper level disturbances to cross the local area
through the period - bringing off and on chances for unsettled
weather across the central plains. It certainly will not rain or
storm across the entire area every day, but expect at least a
chance for precipitation across the local area with each passing
disturbance.

.AVIATION /18Z TAFS THROUGH 18Z MONDAY/...
Issued at 1227 PM CDT Sun Sep 20 2026

For KGRI/KEAR Airports:

MVFR or lower stratus will prevail at both terminals through the
period with generally light northwestelry winds less than 10
KTS. Expect some improvement in CIGS to near 1.5K feet over the
next few hours, with all indications that they will lower again
overnight to around 500 FT along with some light BR. While there
could be a few light showers mixed in, the odds for this are so
low that no mention was made in 18Z TAFS. In addition, contemplated
lower VSBYs overnight as there are some hints in HRRR for dense
fog as well as in LAMP and NAM guidance towards daybreak
Monday, but want to see additional forecast data come in along
these lines before biting. Overall, light northeasterly flow and
near zero dewpoint depressions are favorable for at least more
widespread fog development.
