KEY MESSAGES

- Cooler temperatures settle in behind a cold front with highs in the middle 40s north to middle 60s south.

- Precipitation potential increases this evening focused north of Highway 2 where measurable snow (50-70%) is likely but accumulations likely remain light.

- A secondary cool front with approaching high pressure will bring breezy northwest winds on Wednesday which will combine with low afternoon humidity to lead to potentially critical fire weather conditions.

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

SHORT TERM /THROUGH WEDNESDAY NIGHT/

Issued at 230 AM CDT Tue Mar 10 2026

Early this morning, surface cool front is settling south into the Sandhills, with a pronounced increase in northerly winds in its wake. This front will remain fairly progressive and should continue to move south, clearing the area by daybreak. Colder air will settle into western Nebraska with overnight lows falling into the lower 20s but values closer to 30F further south and east. Steady mid-level clouds are unlikely to dissipate much leaving partly to mostly cloudy skies.

Tuesday/Tuesday Night...high pressure across the north shifts east along the Canadian border as weak low pressure tracks into Kansas. Weak northerly flow early today will support modest cold air advection (CAA) across the area. High temperatures today were trended down slightly as a result, leaning on a blend of MAV and RAP guidance. This produced middle 40s north to middle 60s south. This evening, precipitation potential should increase across the Sandhills into portions of north central Nebraska. Forcing ramps up as a mid-level PV anomaly crosses northern Wyoming. Ascent aloft will be aided by increasing low-level frontogenesis from a reinforcing cool front with EPV reductions suggesting some banding potential. With cold air in place and top down saturation, any rainfall should transition to a wintry mix if not all snow by Midnight CDT. HREF probabilities suggest some travel difficulties are possible as joint probabilities for active snowfall and visibilities of < 1SM climb to around 50-70%. These impacts would be highest for the Highway 20 corridor across the Sandhills with up to 40% potential east of Highway 83. Though snowfall accumulations remain light at or less than 1", even light accumulations can lead to slick spots so travelers are advised to used caution. Low temperatures should fall below the freezing mark for all and threaten some teens across our western zones heading into Wednesday.

Wednesday/Wednesday Night...behind the secondary front, steady northwest winds will become established across the region. High pressure will build west of the Continental Divide. With a fairly strong pressure gradient in place across much of the Central and Northern Plains, gusty northwest winds are likely through the day and into the evening. Though the forecast is dry, the steep lapse rates will extend into the mid-levels and support non-zero instability. This could promote some "virga showers" with gusty erratic winds in their vicinity. Considering this and the expected return of temperatures in the upper 40s to middle 50s allowing afternoon humidity levels to fall to around 15-20%, we are once again concerned about anticipated fire weather conditions. At this time, believe critical conditions are possible with northwest gusts of 25 to 35 mph. Later forecasts may require fire weather headlines but for now, will wait for higher confidence before making any decision on issuing a product. Temperatures fall quickly Wednesday night with lows likely in the 20s for all.

LONG TERM /THURSDAY THROUGH MONDAY/

Issued at 230 AM CDT Tue Mar 10 2026

Confidence continues to increase in a higher end fire weather threat across the area for Thursday. By late Thursday morning, a strong surface low will eject east into the Dakotas, reaching the Great Lakes Thursday night. A surface trough will stretch south from this surface low and is expected to swing quickly through the area Thursday morning. Strong downslope flow establishes in the wake of this surface trough, with flow in the H7-H85 layer strengthening to 40-50kts. Mixing heights look adequate to tap into this higher momentum flow across western Nebraska, despite some high cloud concerns. This points towards westerly gusts strengthening to as high as 45 to 60 miles per hour, particularly for areas west of Highway 83. These winds will unfortunately overlap near record high temperatures and a very dry airmass, setting the stage for critical fire weather concerns. The strong winds will persist into the evening hours, before briefly weakening after sunset. As the surface low begins to move across the Upper Midwest by Thursday evening, a cold front will quickly progress south across the area after sunset. This will lead to a wind shift from west to northwest to north, along with a threat for strong winds with its passage. Guidance has begun to hint at a corridor of enhanced northwest winds (45 to 55mph) across northern Nebraska, where the most robust surface pressure rises are expected. This is all very reminiscent of the February 17, 2026, extreme fire day, both with the afternoon fire threat later compounded with a strong cold front (66kt gust at VTN) after dark. If this were to verify, it points towards the fire weather threat lingering into the early overnight hours across the area. Regardless, Thursday continues to look like a higher end fire weather day, with a threat for large fire growth and rapid fire spread across the area.

As the cold front clears the area by Friday morning, a cooler airmass remains in place across north central Nebraska Thursday afternoon. Strengthening southerly flow will again bring temperatures in the 70s for portions of western and southwest Nebraska. This unfortunately brings yet another day of fire weather concerns, with warm, dry, and windy conditions across western Nebraska. The fire weather concerns persist into Saturday afternoon, with the greatest concerns again across western and southwest Nebraska. A surface low will then eject across the central Plains by Saturday night, bringing a threat for precipitation across the area. Discrepancies between guidance solutions keeps confidence in placement and amounts low for now, though trends will continue to be monitored.

AVIATION /12Z TAFS THROUGH 12Z WEDNESDAY/

Issued at 630 AM CDT Tue Mar 10 2026

Low stratus with MVFR/IFR CIGs persists into early this afternoon across much of the Sandhills and southwest Nebraska, with a return to VFR expected by mid-afternoon. Low stratus and snow then overspreads northern Nebraska after sunset, with MVFR/IFR CIGs and visibilities expected. Snow exits prior to sunrise tomorrow, though low stratus persists through the end of the valid period east of Highway 83.

Winds remain gusty from the northeast through late morning, with gusts of 20 to 30kts continuing. Winds then remain northeasterly this afternoon and evening, at 10 to 15kts.
