KEY MESSAGES

- Critical fire weather conditions appear likely for much of western and central Nebraska on Monday with a Fire Weather Watch now in effect.

- At least elevated to near critical fire weather concerns are expected to last through mid week. Tuesday and Wednesday both have potential for localized near critical to critical fire weather thresholds. Tuesday, the greater concern is for areas east of Highway 83, with the greatest concerns on Wednesday west of Highway 83.

- Well above seasonal temperatures are expected to last all week and into the weekend. Some uncertainty remains in the late week forecast, which will largely depend on a potential plume of Gulf moisture.

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 212 AM CDT Sun May 10 2026

Early this morning, residual showers with a few weak thunderstorms quickly passed from west to east across southwest Nebraska. This was associated with a disturbance that dived southeast across Wyoming and northeast Colorado, leading to strong to severe thunderstorm potential in these areas. An influx of drier air hampered instability in the local area therefore the earlier severe threat was never realized for any of the local forecast area. Rainfall amounts also remained on the lighter side with locations remaining at or below a tenth of an inch. Some light showers may persist in these areas through the early morning on Sunday, but little additional rainfall is expected.

Sunday/Sunday Night...expect a mild and dry day across the area. High pressure will settle south into the area with westerly flow becoming established by daybreak for much of the area as this feature settles south. Drier air will arrive in and combined with building mid-level heights will support eroding clouds and seasonable temperatures. While cooler h85 temperatures will initially settle into the area, modest warm air advection (WAA) will resume this afternoon with steady winds around 10-20 mph. While moisture may mix out slightly in the afternoon, the lack of stronger mixing will prevent minimum humidity values from falling below 25% for most if not all locations. This and lighter winds will keep fire weather concerns low. A warm front will lift north and east through the evening/overnight Sunday. This will fetch richer moisture into the area and should support another mild night. The going forecast is fairly bullish on how cool things get with potential for increases later on. That said, values should generally settle into the 40s for all locations.

Monday/Monday Night...much warmer temperatures along with gusty southwest winds have prompted the issuance of a Fire Weather Watch for all west central Nebraska fire weather zones. Details pertaining to this can be found below in the fire weather discussion. The aforementioned warm front will lift north into South Dakota as a surface low begins to take shape over eastern Wyoming. An approaching thermal ridge will propel h85 and h7 temperatures above the 90th percentile. Within gusty southwest winds, afternoon highs should quickly climb into the upper 80s to lower 90s. While record highs appear to be out of reach (96F and 98F at LBF and VTN respectively), values are certainly in the higher percentile ranges of each site's climatology. Higher level clouds should filter in through the day, but is not expected to have a significant impact on daytime temperatures. As the surface low extends further east into Nebraska, the pressure gradient should constrict and winds actually strengthen heading into the evening as a stout LLJ sets up. A flip is then expected as a crashing Pacific front settles through the area. Further strengthening winds appear possible immediately behind the front as pressures tendencies approach +2-4 hPa/3 hour. Precise timing and expected magnitude of winds remains somewhat uncertain by overall thinking is frontal passage occurs in the predawn hours Tuesday. The persistent winds will keep lows on the mild side, with readings only in the upper 40s to middle 50s west to east.

LONG TERM /TUESDAY THROUGH SATURDAY/

Issued at 212 AM CDT Sun May 10 2026

Winds remain gusty behind the cold front on Tuesday, with northerly winds expected across the region. Strongest wind gusts are expected to remain along and east of Highway 83, with gusts up to 30 mph throughout the afternoon. Highs on Tuesday are expected to be slightly cooler, but remain above average for this time of year, with highs in the upper 70s to lower 80s expected. Even with these slightly cooler temperatures, very dry air is expected across the region, with dewpoints in the 30s. This will cause minimum humidity values on Tuesday afternoon to drop at or below 20 percent across most of the region. The warm, dry, and windy conditions bring at least elevated to near critical fire weather concerns across most of the region. The greatest potential for near critical to critical conditions appears to be areas along and east of Highway 83, where stronger wind gusts are expected.

As for Wednesday, temperatures remain well above average with highs in the 80s across the region. Another round of dry air is expected, with afternoon humidity values once again dropping around 20 percent across most of the region. Southerly winds are expected across the region, with strong wind gusts along and west of Highway 83. Gusts across the Panhandle and western Sandhills are expected to reach around 40 to 45 mph. The greatest concern for near critical to critical fire weather conditions will also remain generally west of Highway 83 with the strong wind gusts. However, at least elevated to near critical fire weather concerns are expected across the entire region, given the warm temperatures, low humidity, and gusty winds.

By late week, uncertainty builds in the forecast as some question remains on the amount of moisture tracking across the region. Latest guidance from the deterministic GFS and ECMWF continues to suggest a plume of Gulf moisture tracking into the region, with potential to bring surface dewpoints into the 50s. If this is realized, then expect higher humidity values in the afternoon, which may help limit fire weather concerns. Additionally, a more moist environment may support some increasing chances for rain and thunderstorms. In fact, GEFS and European ensemble guidance are beginning to show increasing chances for precipitation given the expected moisture plume, bringing around a 40 percent chance of seeing measureable precipitation. However, the NBM remains on the drier side of guidance, suggesting potential for fire weather conditions to continue. Much of the late week forecast will be dependent on whether or not this moisture plume develops and also how moist the airmass becomes. What does remain more certain is continued well above seasonal temperatures, with potential for temperatures to break into the lower 90s Thursday and Friday. Additionally, winds appear to remain gusty late week, but will continue to monitor whether or not winds reach critical fire weather thresholds. This pattern remains for the weekend, as well, with higher confidence in warm temperatures lasting this weekend. Still some question on precipitation chances as well as available moisture, so will continue to monitor forecast trends at this time.

AVIATION /12Z TAFS THROUGH 12Z MONDAY/

Issued at 618 AM CDT Sun May 10 2026

VFR conditions are expected to prevail across western and north central Nebraska today and tonight. Westerly to northwesterly winds will begin to prevail this morning, remaining so through the afternoon. By the evening, winds return to light and variable across the region. For cloud cover today, mid level clouds are expected to persist this morning, with passing mid level clouds through the afternoon. Though cloud cover is expected throughout most of the TAF period, no impacts are expected to ceilings. By the evening, skies are expected to clear.

FIRE WEATHER

Issued at 212 AM CDT Sun May 10 2026

Monday...A Fire Weather Watch has been issued for Zones 204, 206, 208, 209, 210, and 219 for much of the daytime hours. Though a lifting warm front should introduce increasing dew points early in the day, a forming low pressure center over eastern Wyoming/the Nebraska Panhandle will compress the pressure gradient and lead to gusty southwest winds. These favorable winds beneath a fairly strong thermal ridge with 1000-500 thickness values pushing 575+ dam and h7 temperatures near 8-10C. This will propel temperatures to values 15- 25F above normal for Monday. This should lead to fairly expansive critical humidity levels as even more pessimistic output from model blend guidance paints 15% or less afternoon humidity. This is especially true across Zone 204 and western Zone 206 and Zone 208 where a surface trough/pseudo-dryline will push in from the west and, coincident with the warmest temperatures in the area, will also bring with it < 30F dew points. Winds appear to be the most uncertain aspect of the potential event. A quick glance at multiple NWP solutions shows fairly good agreement in h85 flow exceeding 20 knots across the area with some stronger h7 flow over northern Nebraska. It's this area where NBM paints 80% or greater probabilities for exceeding 22 knot (25 mph) gusts with greater than 50% generally elsewhere. Later in the evening, winds should remain steady if not increase slightly as a strong low-level jet forms over the area. This will occur ahead of an approaching Pacific front that will bring about an abrupt wind shift sometime late Monday evening/early Tuesday morning. Gusts may increase at least briefing in the wake of this front and the persistent winds ahead of and behind this feature should limit humidity recovery as Tuesday morning lows likely remain in the upper 40s to lower 50s for all of western Nebraska.
