.DISCUSSION...
Issued at 320 AM CST Thu Dec 18 2025

Light to moderate rain is moving across eastern Nebraska and
western Iowa this morning as a cold front moves across the area.
Winds have generally shifted to northwesterly behind the front
with an ongoing lull in winds before stronger winds develop
later this morning. This all stems from a strong low pressure
system moving across North Dakota into Minnesota today, and as
it deepens we`re seeing a strengthening pressure gradient on
the back-side of the Low generate strong winds across much of
North and South Dakota as well as Nebraska, Iowa, Kansas, and
Missouri. Forecast models indicate likely wind gusts across our
area of 40 to 60 mph with strongest winds in northeast and
portions of east-central Nebraska, indicated by the High Wind
Warnings in place for these areas. Locations under a Wind
Advisory will still see wind gusts 40 to 50 mph today. With
regard to precipitation, rain will be moving out over the next
several hours, but as temperatures fall we do see indications in
our Hi-Res models for the potential for a a band of snow to
develop later this morning over northeast Nebraska. If this
develops, the combination of snow and strong winds could lead to
rapidly reduced visibilities nearing whiteout conditions for a
brief period (snow squall). Right now potential is around 15-20%
chance this happens.

Winds will relax by this evening bringing a long period of
fairly benign weather through the weekend into early next week
with no mentionable chances for precipitation. Fairly zonal flow
sets up across the CONUS leading to small fluctuations in
temperature as weak shortwaves move through at times, but in
general daily high temperatures look to remain in the 40s and
50s through the days leading up to Christmas. I could go on to
explain how a ridge starts to build in early next week, but this
only leads to more of the same benign weather. Looking farther
out at the CPC 8-14 day outlook, they`re predicting more of the
same even through the next week with high confidence in above
normal temperatures continuing and moderate confidence in below
normal precipitation. We do start to see below-normal
temperatures return in their week 3-4 outlook, so that`s
probably our next chance for an appreciable cool-down. This is
supported by ensemble guidance all showing a greater chance for
maintaining above normal temperatures into the New Year.

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1052 PM CST Wed Dec 17 2025

Strong winds remain on track with current gusts of 20-30 kts
expected to pick up into the 40-55 kt range on Thursday with any
remaining southerly winds becoming northwesterly early in the
period. Could also see some low level wind shear early in the
period, especially at OFK with 50 kt winds at 2000 ft agl, but
with stronger surface gusts moving in, that threat should
diminish. As the winds shift, could also see some light rain
showers along with MVFR ceilings. A few pieces of guidance also
continue to hint at snow shower potential from 12 to 18Z, though
confidence remains low on if it develops (15-20% chance). If it
does, could see some brief MVFR to IFR visibility, depending how
heavy it is. Otherwise, outside of precipitation, expect VFR
conditions with winds diminishing Thursday evening.
