.SHORT TERM /THROUGH FRIDAY/...
Issued at 355 AM CST Wed Nov 19 2025

Currently, patchy fog persists across portions of southwest Nebraska
early this morning. Temperatures range from the low 40s in north
central Nebraska to the low 30s in the Platte River Valley. Aloft,
southwesterly flow prevails ahead of an upper low centered over
southern California.

For today, expect southerly flow to strengthen into this afternoon
as surface low pressure deepens across eastern Wyoming. By this
afternoon, the surface low will drift east into south central South
Dakota, dragging a surface trough to near Highway 83. Southwest
winds ahead of this boundary will boost highs back into the 50s
today, though not quite as warm as further west. West of HWY 83,
westerly downslope flow will lead to temperatures climbing back into
the low to middle 60s for much of the Sandhills.

Attention then turns to the aforementioned upper low, currently
centered over southern California, as it ejects east into the
Plains Thursday into Friday. An associated surface low will
eject out of southeastern Colorado by Thursday night, moving
across southern Kansas Friday morning. To the north of this
surface low, a deformation axis will pivot north across northern
Kansas and into far southern Nebraska. Guidance continues to be
in good agreement with the bulk of precipitation remaining
across Kansas and well to the south of the area. That said,
accumulations of ~0.25-0.50" may spread as far north as I-80
Thursday night into Friday. Confidence in the northward extent
of precipitation remains low for now, with likely a sharp cutoff
in amounts. This is driven by drier high pressure spilling
south into the area Friday. This will likely limit any
precipitation to areas south of HWY 2. The system begins to
slowly exit the area Friday night, with any lingering
precipitation ending across southwest Nebraska prior to sunrise
Saturday.

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
Issued at 355 AM CST Wed Nov 19 2025

Northwest flow establishes aloft in the wake of the departing upper
low, leading to drier conditions into the weekend. Persistent warm
advection boosts highs back into the upper 50s to low 60s and should
lead to a pleasant weekend across the area. By early next week, a
big pattern shift may be on the way across much of the central US.
Guidance has begun to suggest a much colder airmass for the majority
of the country east of the Rockies, arriving by early to middle next
week. This is in response to a deep upper low moving along the
International Border through early week. This could bring a return
of much colder highs (highs in 30s) for much of next week, and will
need to be monitored closely. With cold air also looking to be in
place, will have to watch for a threat for wintry precipitation,
especially with the increasing holiday travel.

.AVIATION /12Z TAFS THROUGH 12Z THURSDAY/...
Issued at 520 AM CST Wed Nov 19 2025

Low stratus and fog persists across much of southwest Nebraska
this morning, with IFR/LIFR persisting. This low stratus and fog
will erode by late morning, with VFR conditions returning to all
terminals this afternoon.

A frontal boundary will stall near Highway 83 this afternoon,
with southwest winds of 10 to 15kts expected east of Highway
83. West of Highway 83, west winds are expected, also at 10 to
15kts.
