.KEY MESSAGES...

- Critical fire weather conditions are expected across all of
  western and north central Nebraska today, due to a combination
  of abnormally warm temperatures, low relative humidity, and
  very strong westerly winds. Across western Nebraska, westerly
  wind gusts up to 65 mph are expected this afternoon.

- This evening, a cold front brings a second round of strong
  winds across north central Nebraska. Northwesterly wind gusts
  behind the front of 55 to 60 mph are expected this evening
  into the overnight hours.

- Near critical fire weather concerns are expected again
  Saturday, as warm, dry, and windy conditions continue across
  the area.

- Light rain and snow is possible behind a cold front Saturday
  night into Sunday. At this time, the greatest snow
  accumulations are expected for areas along and north of HWY
  20.

.SHORT TERM /THROUGH FRIDAY NIGHT/...
Issued at 245 AM CDT Thu Mar 12 2026

Strong downslope flow today will bring strong westerly winds and
warm air advection across the region. This will usher in abnormally
warm high temperatures, with highs roughly 20 to 25 degrees above
normal. In fact, highs today are expected to push into the 70s
across most of the region, with some locations in southwest Nebraska
possibly pushing into the upper 70s. These very warm temperatures
will also bring very low relative humidity this afternoon, with
minimum values dropping into the 13 to 23 percent range.

In addition to the very warm temperatures and low humidity, the
downslope flow will also bring strong westerly winds across the
entire region this afternoon. The strongest winds generally remain
along and west of Highway 83 this afternoon, with sustained westerly
winds around 35 to 45 mph and gusts up to 65 mph. East of Highway
83, winds still remain strong, with sustained west winds of 25 to 30
mph gusting to 45 mph. For areas west of Highway 83, a High Wind
Warning goes into effect this morning through the evening. Strong
westerly winds will make for difficult travel on north-south
oriented roads due to crosswinds. Additionally, and more
importantly, the combination of very strong winds, abnormally warm
temperatures, and low relative humidity will lead to critical fire
weather conditions across all of western and north central Nebraska.
In addition to the High Wind Warning, a Red Flag Warning is in
effect for all of western and north central Nebraska this afternoon
into the evening. In fact, the entire state of Nebraska is under a
Red Flag Warning this afternoon, as very widespread critical fire
weather conditions are expected. Any fire starts this afternoon will
rapidly grow and spread, becoming difficult to contain.

As afternoon transitions into the evening, a cold front tracks in
from the north. With this cold front, another round of strong winds
tracks into the region, this time across portions of north central
Nebraska. Behind the front, strong sustained northwesterly winds of
25 to 30 mph are expected, with winds gusting 55 to 60 mph. With
increased confidence in these higher winds, have issued a second
High Wind Warning for areas east of Highway 83, and mostly along and
north of Highway 2 for Thursday evening into early Friday morning.
This will have some overlap with the ongoing Red Flag Warning in the
early evening, so again, any fire starts will rapidly grow and
spread. Winds are expected to finally diminish shortly before
sunrise Friday morning.

As for Friday, a temperature gradient sets up across the region.
Cooler temperatures are expected across north central Nebraska in
the wake of the cold front. Highs across north central Nebraska are
expected to drop into the 40s. Across the Sandhills, highs are
expected to remain in the 50s. Across southwest Nebraska, warmer
temperatures remain, driven by some additional downslope flow, where
highs in the 60s are expected, with a few locations potentially
breaking into the lower 70s. The warmer temperatures across far
southwest Nebraska will contribute to lower relative humidity values
in the 20 to 25 percent range. Southerly winds are expected to
remain around 10 to 15 mph, with gusts up to 25 mph at times. This
may lead to some additional elevated to near critical fire weather
concerns across southwest Nebraska on Friday afternoon. This threat
will largely be driven on the eastern extent of stronger wind gusts,
so will continue to refine the forecast in the next few forecast
cycles.

Friday night, a band of showers is expected to track south across
South Dakota, bringing slight chance to chance PoPs across far north
central Nebraska. If precipitation is realized with this system,
expect that precipitation initially starts as rain/snow mix, before
switching over to snow as overnight lows plummet into the 20s.
However, any precipitation amounts are expected to remain very
light, with a dusting of snow expected at most. This would roughly
be a couple hundredths of an inch liquid, so very little in terms of
wetting precipitation.

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Issued at 245 AM CDT Thu Mar 12 2026

Surface low pressure will deepen across eastern Colorado/Wyoming
Saturday morning, before ejecting east into western Nebraska and
Kansas by Saturday evening. This leads to a constricting surface
pressure gradient across the area, leading to increasing southerly
flow ahead of this low, and westerly flow behind a surface trough
moving into the Sandhills in the afternoon. The greatest fire
concerns are expected to develop behind this surface trough, as the
strong downslope winds overlap warm and very dry conditions.
Westerly wind gusts of 25 to 35 miles per hour can be expected
Saturday afternoon, with the strongest winds across the western
Sandhills.

By Saturday night, a cold front will push through the area as the
surface low ejects east, leading to increasing cold advection. This
will promote ample mechanical mixing to lead to strong northerly
winds through the overnight hours, with widespread gusts of 30 to 40
miles per hour Sunday morning and into the afternoon. Strengthening
mid-level FGEN will also lead to snow development across southern
South Dakota and far northern Nebraska. At this time, confidence in
impactful snow accumulations is highest north of the area across
South Dakota, though increasing probabilities stretch further south
into portions of northern Nebraska. For now, snow amounts locally
look highest near and north of HWY 20, though minor adjustments in
storm track will lead to drastic changes in snow amounts. This will
need to be monitored closely, with a sharp gradient expected on the
southern side of the axis of heaviest snowfall.

Attention then turns to increasing fire concerns, as guidance has
begun to hint at very anomalous upper ridging as we head
towards midweek. Temperatures quickly moderate back to above
average by Tuesday, with the potential for highs approaching
record territory for Wednesday into late week. Ensemble guidance
hints at rather impressive upper ridge, with H5 heights
approaching climo maximums across much of the western and
central US next week. This is further reinforced by very warm
low level temperatures, with ensemble guidance suggesting H7-H85
temperatures approaching the 99th percentile climo as well.
This points to impressive warmth for late March, with
probabilities for even highs approaching monthly records
beginning to creep upwards. Trends will need to be monitored
closely, as the prolonged record warmth could spell both a
return of fire concerns and could worsen ongoing drought
conditions across the area.

.AVIATION /06Z TAFS THROUGH 06Z FRIDAY/...
Issued at 1220 AM CDT Thu Mar 12 2026

VFR conditions are expected to prevail through Thursday night
across all of western and north central Nebraska. Winds quickly
strengthen from the west Thursday morning, with widespread gusts
of 45 to 55kts for all terminals Thursday afternoon. A cold
front then passes through the area after sunset Thursday,
leading to strong northerly winds with its passage. Another
period of 45 to 55kt gusts are expected into Thursday night,
particularly for north central Nebraska terminals.

.FIRE WEATHER...
Issued at 245 AM CDT Thu Mar 12 2026

Fire concerns greatly increase this afternoon, with widespread
critical fire concerns expected. Temperatures in the 70s will
combine with dry air and lead to humidity falling to as low as 12 to
20 percent across the entire area. Very strong winds are expected to
develop as well, with sustained westerly winds of 35 to 45 mph and
gusts up to 65 mph. East of Highway 83, winds still remain strong,
with sustained west winds of 25 to 30 mph, gusting to 40 mph. This
will overlap the low humidity and lead to critical fire conditions
across all of western and north central Nebraska. This will lead to
erratic fire spread and rapid fire growth. A strong cold front will
also pass through the area this evening, leading to a wind shift
from west to northwest. A corridor of very strong northwest winds
(60+ miles per hour) is expected across northern Nebraska with its
passage. A Red Flag Warning is in effect for all of western and
north central Nebraska today.

Elevated to near critical fire concerns persist into Friday and
Saturday, primarily across western and southwest Nebraska. A brief
cooldown on Sunday lessens fire concerns, before temperatures
quickly warm and could challenge record highs by middle next week.
This could mark a return of elevated to near critical conditions to
the area yet again.
