KEY MESSAGES

- Well above normal temperatures and gusty west winds will lead to increased fire weather concerns the next two days with a Fire Weather Watch in place for portions of western Nebraska Monday.

- A pair of cool fronts later this week will bring a few days of cooler temperatures and precipitation potential to the local area, including the threat of light snow.

- Rain and snow is expected across portions of the Sandhills and northern Nebraska Tuesday into Wednesday. At this time, any accumulations are expected to remain light.

- Critical fire weather concerns are looking increasingly likely on Thursday due to a combination of strong west winds and very low relative humidity.

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 304 AM CDT Sun Mar 8 2026

Early this morning, skies remain most clear with high cirrus covering the central and northern Rockies. This sky cover was tracking north to south and should remain west of the area through the duration of Sunday. A modest surface track was stalled across central Nebraska, hinted at by a subtle wind shift but increased moisture to the west of the feature where dew points were in the middle to upper 20s versus upper teens to lower 20s east. Steady westerly winds will keep low temperatures on the mild side with middle 20s to middle 30s, or nearly 5 to 15F above normal for early March.

Sunday/Sunday night...surface trough will continue to slowly track south and east as Pacific origin air continues to infiltrate the area from the northwest. Eventually, winds will back to the southwest as lee troughing deepens later in the day. This may draw in drier Desert Southwest air while also boosting afternoon highs considerably from Saturday's values. Saturday evening RAOB data measured an h85 temperature of 4.4C which nears the median value for the date in the station's climatology. Looking ahead to today, persistent downsloping winds will help to push these values into the middle to upper teens. With snowpack effectively erased, temperatures should climb quickly across the area. Afternoon highs received a good bump into the upper 60s and middle 70s. These values are roughly 20 to 30F above normal for early to middle March. With h7 trajectories nearly perpendicular to the Front Range, expecting to see very dry air working in from the west. This will promote increased fire weather concerns with details contained below in the Fire Weather Discussion. Steady west winds continue overnight Sunday into Monday. This will keep temperatures on the mild side with lows ranging from the middle 30s to lower 40s.

Monday/Monday night...what appears to be the day of greatest fire weather concern with details contained below in the Fire Weather Discussion. Westerly mid-level flow will strengthen as the Polar Jet settles south. A subtle shortwave will cross the Central Rockies with lee cyclogenesis leading to a surface low developing over eastern Wyoming. As a surface trough works down from the higher terrain, westerly winds will increase markedly as more significant dry air invades the region. The warming and drying of air descending the topography will support even warmer temperatures as h85 temperatures make a run at 20C in our western zones. The going forecast calls for widespread 70s to near 80F in our far south, but this still undercuts NBM median values as well as most if not all statistical outputs. The MAV solutions, which handles downslope dry regime temperatures fairly well, suggests numerous spots hit 80F including LBF which would be within 2F of a new record high. Gusty west winds will largely be limited to the Sandhills, with fairly quick decreases further south and east from this area. A notable cold front will stall along the Nebraska/South Dakota border late in the day, with a late push from increasing flow orthogonal to the boundary as central low pressure shifts east. The result will be a quick cooldown late Monday night. For now, forecast lows range from lower 20s in the northwest to lower 30s south and east. As timing of the front becomes more precise, expect some variability in these forecast values.

LONG TERM /TUESDAY THROUGH SATURDAY/

Issued at 304 AM CDT Sun Mar 8 2026

A cold front quickly clears the area by late Tuesday morning, as a surface low ejects east across Nebraska through the early morning hours. This will bring a return of cooler temperatures for Tuesday afternoon, with highs in the middle 40s across northern Nebraska to the upper 50s south of I-80. This system will also bring a return of precipitation, primarily across the Sandhills and northern Nebraska. This is in response to the mid-level trough axis ejecting across the area, with a constricting thermal gradient and increasing FGEN with its passage. The increasing forcing will lead to initial light rain and snow quickly moving from northwest to southeast across this area, with an all snow p-type expected overnight. The speed of this system combined with some low level dry air that will need to be eroded should keep any precipitation amounts light across the area. NBM probabilities continue to support this, with probabilities of >0.10" only maximizing as high as 30-40% north of HWY 2. Associated snow amounts are expected to remain <1" at this time.

Northwest flow returns aloft in the wake of this system, pointing to drier conditions as we head into late week. At least some fire concerns look to quickly return by Wednesday and become very concerning by Thursday. As for Thursday, the threat for critical fire concerns is becoming increasingly likely, as strong downslope flow returns to the area. Strong H7-H85 flow on the order of 40- 50kts will overspread western Nebraska during the afternoon hours Thursday. As ample diurnal mixing is achieved, this high momentum flow will lead to wind gusts increasing to as much as 45 to 55 miles per hour. Some guidance suggests the potential for even higher (55+ mph) though confidence in this remains low for now. However, these strengthening wind gusts will overlap near record temperatures (70s to near 80) and humidity values in the teens. This points towards a period of critical fire concerns across the area on Thursday. The one caveat at this range looks to be a threat for high cloudiness, which could impact the degree of mixing somewhat. Trends will need to be monitored for concerning fire weather by Thursday. Another cold front then pushes through the area Thursday night, bringing a return of cooler highs (50s to low 60s) for Friday and the weekend. Some threat for precipitation may return to the area as well, though confidence remains low in this for now.

AVIATION /06Z TAFS THROUGH 06Z MONDAY/

Issued at 1130 PM CST Sat Mar 7 2026

VFR conditions are expected to prevail through Sunday night across western and north central Nebraska. Winds remain west through sunrise, at 10 to 15kts. Winds then strengthen Sunday afternoon, with westerly wind gusts of 20 to 30kts for all area terminals.

FIRE WEATHER

Issued at 304 AM CDT Sun Mar 8 2026

Fire weather concerns remain high over the next two days, culminating in a Fire Weather Watch for much of western Nebraska on Monday.

Sunday...west to southwesterly flow will promote deep mixing into an approaching thermal ridge nosing in from the southwest. Forecast highs will climb into the upper 60s to lower 70s, or approximately 20-30F above normal for early March. While the anomalous warmth is cause for concern, the potential for reaching critical humidity levels (< 15% for 204, 206, 208, 210, 219; < 20% for 209). HREF probabilities of falling below 20% RH are largely limited to areas south of the Platte River system where winds are expected to be the weakest. Gust potential over the Sandhills is nominal, with 60%+ signal from NBM output of exceeding 34 knot (~39 mph) gusts. It's noteworthy to point out that high resolution guidance in addition to the GFS, with it's over-mixing bias, does not explicitly show critical humidity levels being met. Typically, with the lack of a signal from these particular sets of guidance, it casts additional doubt on seeing critical humidity levels reached. Because of this as well as the lack of overlap of lower humidity and the stronger gusts, will continue to highlight near-critical conditions.

Monday...the greater fire weather concern day for the early week with a Fire Weather Watch for much of western Nebraska. A mid-level disturbance will cross the Laramie Range with a surface low taking shape over eastern Wyoming. This will result in a surface trough with gusty west to southwesterly winds tracking west to east across the area. Temperatures off the surface will see a sizable boost with increasing influence of a thermal ridge anchored across the central and southern Rockies. With increasingly dry air working in from the Southwest, humidity levels should quickly plummet and reach critical values by early afternoon. The afternoon temperature forecast was increased 3-5F across the board, but given the overall pattern, this may not be enough. The going forecast falls closer in line with the NBM 25th percentile output and is closer to MET guidance. Believe further increases with later forecasts may be necessary, perhaps closer in line with MAV guidance, which suggests record highs may be in jeopardy at a few sites (LBF, IML, and maybe BBW). With further increases in temperatures but little to no adjustments to low-level moisture, humidity levels falling below 15% for many locations appear to be a safe bet. Wind gusts should see a slight increase from Sunday's peak speeds, especially across the Sandhills. NBM probabilities for exceeding 34 knots ranges from 60- 90% for Zone 204, and westerly Zone 206/208. Forecast soundings show deep mixing into stronger h7 flow with momentum transfer supporting gusts closer to 40 to 45 mph. What casts some uncertainty in how exactly the day will evolve is a steady stream of high level clouds working off the central Rockies. While low-level drying of air is likely as air descends west to east across the Panhandle, forecast highs and boundary layer mixing could be hampered enough to limit gusts from achieving their full potential. For now, confidence is high enough to warrant a Fire Weather Watch for much of our western zones with adjustments possible with later forecasts.

Near record temperatures quickly return to the area by Thursday, bringing a quick return of fire weather concerns. These temperatures in the 70s to low 80s will combine with dry air to push relative humidity values into the teens Thursday afternoon. Most concerning, strong west winds look to develop across western Nebraska into the Sandhills as well, with gusts as high as 45 to 55 miles per hour possible. This looks to lead to a period of critical fire concerns Thursday, and points towards a very concerning setup for large and rapid fire spread. Trends will need to be monitored very closely and future fire weather headlines may be needed across much of western and north central Nebraska on Thursday.
