KEY MESSAGES

- Critical fire weather conditions are expected Monday with Red Flag Warnings in place for much of western Nebraska.

- A cool front will dive south early Monday evening into Tuesday, bringing cooler temperatures as well as the potential for a light rain/snow mix if not all snow for portions of the area.

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

SHORT TERM /THROUGH TUESDAY NIGHT/

Issued at 245 AM CDT Mon Mar 9 2026

Early this morning, stray mid-level clouds continue to shuffle west to east across the area. Westerly winds remain elevated across the area with stray gusts in the 20 to 25 mph range noted over the Sandhills into the Panhandle. KLNX VWP data shows 20-30 knot winds just off the surface and this is likely to persist through the remainder of the predawn hours. The result is mild overnight lows once again with values likely to remain above the freezing mark and some areas likely holding onto the 40s.

Monday/Monday Night...enhanced mid-level flow across the Northern CONUS will slowly settle south overnight into early Monday. Zonal mid-level flow will continue through the day. As a mid-level disturbance approaches the Laramie Range by early afternoon, a surface low and associated lee troughing will form to the west. Gradually through the afternoon, this low will track east along the Nebraska/South Dakota border lifting a warm front north and east through western Nebraska. Behind this feature, winds will strengthen beneath a modest h7 speed max nearing 40 knots. With strong downsloping winds, temperatures should again quickly climb this afternoon across the whole forecast area. Leaned heavily on MET/MAV guidance, which paints upper 60s to near 80F northeast to southwest, as these solutions were the warmest and showed fairly good agreement in our warmest areas (Highway 2 and points south). It's these areas where upper 70s to near 80F is in place and a few record highs could be threatened. Details pertaining to that can be found in the Climate section below. Given the expected warm temperatures of up to 30F above normal, invading dry air, and gusty winds, fire weather concerns are the main issue for today and details can be found in the following Fire Weather discussion. Late tonight, as the weak surface low continues to move east, a trailing cold front will quickly clear the area by early Tuesday morning. Winds behind this front should be gusty as pressure rises quickly fill in the region. Cold air advection (CAA) will lead to cooler lows across the area with forecast values in the middle 20s to low 30s.

Tuesday/Tuesday Night...northerly flow will continue through the day and prolong CAA. Forecast highs were decreased slightly as a result utilizing a NAM/MET blend which typically handles CAA setups better. Forcing will lag the front by a few hours and be more closely tied to a PV anomaly crossing Wyoming. While PoPs may arrive as early as late morning near the Pine Ridge, more widespread precipitation potential should hold off until Tuesday evening into early Wednesday. Highs during the day will still be plenty warm to support all rain, with middle 40s north to near 60F south, but as cooler air continue to filter in a transition to at least a snow mix if not all snow appears likely during the overnight. Top down saturation should allow for a clean rain to snow transition and as mid-level forcing peaks closer to Midnight, moderate to perhaps briefly heavy snowfall will be possible. NBM probabilities of exceeding 0.05" liquid equivalent climb to around 60% along the Nebraska/South Dakota border but NAM/GFS deterministic outputs are both further south and show bullseyes of 0.10" for a few locations. For now, confidence is fairly low in seeing the heavier scenarios play out. Because of this, snowfall totals remain light at one inch or less for anywhere in the area. We can't rule out some necessary increases in expected snowfall with later forecasts so stay tuned. The colder incoming air should lead to a fairly cold night with lows in the upper teens to middle 20s for western Nebraska.

LONG TERM /WEDNESDAY THROUGH SUNDAY/

Issued at 245 AM CDT Mon Mar 9 2026

Northwest flow establishes aloft into midweek, pointing to drier conditions across the area. Though temperatures will be much cooler on Wednesday (highs in upper 40s to low 50s) versus earlier in the week, very dry air will still push humidity values to as low as 18- 25% Wednesday afternoon. Winds remain gusty from the northwest through the day as well, with gusts of 25 to 30 expected for all. This will lead to elevated to near critical fire weather concerns.

Confidence continues to increase in a higher end fire weather threat across the area for Thursday. As strong downslope flow establishes by Thursday afternoon (H7-H85 flow ~40-50kts), wind gusts will increase to as high as 45 to 55 miles per hour for much of western and southwest Nebraska. These strong west wind gusts will overlap near record temperatures and relative humidity values in the teens. The current forecast continues to sit on the lower end of the guidance envelope (near the 25th percentile), with highs in the lower to middle 70s. Should these temperatures continue to trend warmer, with 50th percentile guidance in the upper 70s/low 80s, this will only lead to lower relative humidity and further increase fire concerns. The one caveat at this range looks to be a threat for high cloudiness, which could impact both the degree of mixing and high temperatures somewhat. Regardless, confidence is increasing in a higher end fire weather day, with a threat for large fire growth and rapid fire spread across the area.

A cold front then passes through the area Thursday night, as a surface low ejects across Kansas and Missouri. This brings a return of cooler temperatures Friday, primarily for north central Nebraska. Warmer temperatures remain across southwest Nebraska, and fire concerns may persist into late week as well. A second cold front pushes through into Sunday morning, bringing a return of cooler temperatures for the entire area as we head into early next week. This could also bring a return of precipitation, though confidence in this remains low for now.

AVIATION /12Z TAFS THROUGH 12Z TUESDAY/

Issued at 612 AM CDT Mon Mar 9 2026

VFR conditions are expected to prevail through tomorrow morning across western and north central Nebraska. Winds strengthen from the west-southwest by late this morning, with gusts of 20 to 30kts for all terminals this afternoon. Winds briefly weaken from the south this evening, before a cold front moves through after sunset. North wind gusts of 20 to 25kts can be expected with its passage.

FIRE WEATHER

Issued at 245 AM CDT Mon Mar 9 2026

Red Flag Warnings remain in effect for Zones 204, 206, 208, and 210 on Monday.

Approaching mid-level disturbance will foster a developing low pressure center over eastern Wyoming by midday. As this feature tracks east along the Nebraska/South Dakota border, a warm front will lift north and east across the area. The resulting strengthening west to southwesterly winds will boost afternoon highs to near record levels with values in the upper 70s to near 80F. Deep mixing within the warming/drying downslope winds will promote strong momentum transfer wind gusts beneath a belt of stronger winds around h7 (~3km AGL). Though mid and high level clouds may hamper the diurnal warmup slightly, confidence is fairly high in afternoon temperatures. Higher resolution guidance is fairly bullish on critical humidity levels with many locations south of Highway 2 and west of Highway 183 falling into the lower teens and potentially approach single digits in portions of Zone 210. Winds should be strongest across the western Sandhills where peak gusts should climb up to 40 mph. Elsewhere, gusts should fall off considerably with peak speeds of 20 mph or less. These marginal winds are the justification for omitting Zones 209 and 219 at this time. As the frontal boundary sags south tonight, winds should abruptly shift from westerly to northerly and gusts may remain elevated for a brief moment. Even with this potential, the decision was made to keep the end time as is due to the magnitude of cold air coming in should allow for reasonable humidity recovery within the first few hours of frontal passage.

After a brief return of cooler temperatures and increased humidity on Tuesday, fire concerns are expected again for Wednesday and this persists into late week. Though cooler highs are expected Wednesday (highs in upper 40s to 50s), very dry air will lead to low relative humidity overlapping gusty northwest winds (20 to 30mph). Elevated to near critical fire concerns are expected on Wednesday.

Attention then turns to a potentially higher end fire weather day on Thursday across the area. Near record 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.
