.SHORT TERM /THROUGH FRIDAY/...
Issued at 402 AM MDT Thu Sep 18 2025
KCYS radar and observations early this morning show showers have
moved out of the CWA. The upper-level low responsible for the
precipitation over the last few days has moved eastward into South
Dakota. As a result, coverage of precipitation has decreased.
However, wrap around moisture on the backside of the low has
contributed to low stratus currently being observed across the
eastern half of the CWA. Wrap around moisture and calm winds may
also lead to some patchy fog this morning. Low stratus will begin to
dissipate later this morning as the low continues to slowly move
eastward. Due to the sluggish nature of this system, clouds will be
slow to clear out of the Nebraska panhandle. A few stray showers
could also make it into the panhandle through the morning and into
the afternoon hours. By the evening, most clouds and any lingering
showers should be out of the CWA. With the low gradually moving out,
warmer temperatures will move into the area. High temperatures today
will be almost 10 degrees warmer than Wednesday thanks to more
sunshine and warmer and drier air aloft.
Early Friday morning, a weak upper-level shortwave will graze the
northern tier of the CWA. This shortwave will have enough lift and
moisture to generate a few showers Friday morning. Locations in
Niobrara County and the northern Nebraska panhandle may wake up
to a wet ground Friday morning. Luckily, this shortwave is
quick moving and will be out of the CWA by the afternoon. The
rest of Friday will be dry and pleasant as warmer and drier air
continues to move in. High temperatures will be about 5 degrees
warmer than Friday, with most locations in the 70s under partly
cloudy skies.

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Issued at 245 PM MDT Wed Sep 17 2025
While periods of active weather will be ongoing during the long
term for regions bordering our CWA, our overall area looks to
remain mostly quiet as we move into next week. Friday should see
clearing precipitation but areas of clouds lingering and highs
still in the 70`s for most of the CWA. Moving into the weekend,
we`ll see the influence of a ridge moving in to warm our region
up, but a passing shortwave to the north should bring just
enough energy to produce a few showers or storms mainly in the
high terrain or adjacent regions on both Saturday and Sunday.
Into Monday a strengthening system will pass across and while
we`ll see our temperatures drop once again into the widespread
70`s, the bulk of the moisture associated with this feature will
be to our north and east and precipitation chances are expected
to be overall fairly meager to nil outside of once again the
high terrain. And then by Tuesday ridging starts to build back
in as we`ll see temperatures rising once again to move into the
middle of next week. Overall there is moderate to high
confidence in the forecast with ensembles agreeing on the
overall forecast pattern and the features associated within,
with the primary discrepancies lying with some minor variances
in strength and placement.

.AVIATION /12Z TAFS THROUGH 12Z FRIDAY/...
Issued at 539 AM MDT Thu Sep 18 2025
Low stratus continues to linger across areas east of the Laramie
Range, affecting KCYS and western Nebraska terminals. Low stratus
will likely continue throughout much of the morning across the
Nebraska panhandle, leading to MVFR CIGs. Clouds will lift by late
morning/early afternoon, leading to VFR conditions later in the
day.
