KEY MESSAGES

- Elevated to near-critical fire weather conditions are again likely for much of western and central Nebraska on Friday.

- A passing disturbance will bring additional rain and thunderstorm chances to the area on Saturday with the threat for severe weather low.

- Well above average temperatures are expected next week, with highs returning to the 80s. Highs on Monday are expected to break into the lower 90s.

- With the warm temperatures, low humidity is expected nearly every day next week. Gusty conditions are also expected nearly every day, bringing near daily fire weather concerns. Confidence is highest for at least elevated to near critical fire weather conditions Monday and Wednesday.

SHORT TERM /THROUGH SATURDAY NIGHT/

Issued at 216 AM CDT Fri May 8 2026

Early this morning, a few areas of rain showers were crossing west central Nebraska. The most notable are were a narrow band just south of the Highway 20 corridor in north central Nebraska. This was forming on the forward edge of modest h7 fgen. Though on the northern periphery of steeper mid-level lapse rates, no thunder was anticipated. Lingering dry low-level air, characterized by surface dew point depressions exceeding 15F, was inhibiting some precipitation from reaching the surface but enough lift allowed for some lower level saturation which yielded light rain at KANW. Believe this potential should persist through the overnight hours and even with little to no QPF for many, will maintain a Slight Chance (up to 20%) mention through daybreak.

Friday/Friday Night...expecting another mild day with breezy north winds. A subtle shortwave will dive southeast out of central Wyoming early. This will propel a surface boundary further south and lead to northerly sustained winds through the day. Even with the northerly flow supporting weak cold air advection (CAA), temperatures will remain quite warm. Afternoon highs were boosted 2-3F across the forecast area, largely due to warm h85 temperatures in the 14-18C range, fairly dry air, and gusty winds promoting a well mixed boundary layer. All of these will combine to lead to some fire weather concerns. Leaned on MAV/MET guidance with some influence from the NAM12 for afternoon highs. This produced fairly widespread 70s, reaching around 75F southeast of an Imperial to Butte line. Modest flow off the surface will continue as a belt of stronger h7 flow will sit over northern Nebraska. Forecast soundings show adequate mixing to tap into these stronger winds with momentum transfer gusts likely supporting gusts around 30 mph, decreasing to around 20-25 mph for areas south of an Ogallala to Burwell line. As the shortwave trough settles southeast, subsidence may draw some drier air to the surface with afternoon humidity minimums falling to around 20%. While this remains above critical levels for most of western Nebraska, Zone 209 bears close watching with the higher humidity criteria. For now, believe a few locations may touch Red Flag Warning criteria in this zone, but should fall short of hitting for three hours. HREF mean humidity minimums during the afternoon fall to around 20% and similarly, probabilities of seeing < 20% RH and > 15 mph (sustained) winds is less than 20%. This seems reasonable as an expansive afternoon cumulus field should develop and may support less mixing. So after careful consideration and collaboration with eastern neighbors, have opted to forego any headline at this time. Northwesterly flow will lead to some increased convergence downstream of the Black Hills. NWP guidance remains fairly pessimistic but will insert a small mention of light rain showers in close proximity to the Pine Ridge. Other output suggest some steep lapse rates above the developing cu field to support some spotty showers during the afternoon. Confidence in any shower yielding precipitation that reaches the ground is low so will maintain a dry forecast during the day for most locations. Beneath increasing clouds, mild overnight temperatures are again expected with lows holding in the 40s.

Saturday/Saturday Night...northwest flow will continue as ridging stalls across the western CONUS. Another shortwave impulse will dive southeast along the Northern Rockies early in the day. This will drive a cool front south into western Nebraska by midday. Uncertainty in placement of the front by early afternoon limited confidence in afternoon highs. Recent NWP output has suggested placement near the I-80 corridor by early afternoon. With stronger northerly flow across much of the local area, forecast highs have fallen some. Though 70s to near 80F appear on track for southwest and central Nebraska, a few locations in the north may hold onto the 60s. This is hedging towards CAA winning out which models tend to not handle the best but should be considered medium confidence at best. As forcing increasing from an approaching PV anomaly and developing fgen, scattered showers and a few thunderstorms will become possible favoring the western Sandhills through southwest Nebraska. While deep-layer shear will be moderate, instability will again be lacking and this will limit the threat for strong to severe thunderstorms with greater focus south and east of the area closer to the now stalled boundary and influx of greater low-level moisture. Still though, cannot rule out a stronger storm with gusty winds and small hail during the afternoon and evening hours. With activity being showery convection, QPF will be spotty. Some locations may see wetting rains while adjacent areas fail to record measurable rain. Believe HREF ensemble max output is vastly overdone with probability matched mean output being more reasonable and suggesting spotty amounts nearing 0.25" while most locations fail to see 0.10". Precipitation potential should persist into the evening hours, though likely in lesser coverage and intensity. Persistent cloud debris should hold temperatures on the milder side, even as cooler air filters in. Lows will touch the middle 30s in the western Sandhills but favor upper 30s to lower 40s elsewhere.

LONG TERM /SUNDAY THROUGH THURSDAY/

Issued at 216 AM CDT Fri May 8 2026

By Sunday, an upper level ridge is expected across the western United States, with an upper level low over the Ontario-Quebec border. This will keep northwesterly flow aloft across western Nebraska, with the ridge remaining just to the west of the forecast area. For Sunday, near seasonal highs are expected, with forecast highs in the upper 60s to lower 70s. Sunday night, the upper level low tracks further to the east, allowing the ridge to begin tracking over western Nebraska. This will set the stage for well above seasonal temperatures through the work week.

As the upper level ridge tracks further over western Nebraska Monday, a shortwave trough tracks across the northern Plains, causing a slight flattening of the ridge. As an intensifying surface low tracks across the Dakotas, gusty southwesterly winds are expected across western and north central Nebraska. In addition to this, warm air advection is expected across the region, bringing well above seasonal temperatures. In fact, highs on Monday may be pushing near 20 degrees above average, bringing highs in the upper 80s to lower 90s. This brings at least hot and windy conditions Monday, the main question will be humidity. There is a notable difference in the ECMWF and GFS solutions for surface dewpoints, with the ECMWF trending towards higher dewpoints across the region. However, the GFS and NBM trend towards lower dewpoints, and thus, lower relative humidity values. All three at least show a gradient developing across the Highway 61 corridor, with lower humidity values to the west. As the forecast currently stands, at least elevated to near critical fire weather concerns may be expected Monday afternoon, with the highest confidence for areas along and west of Highway 61. Given that there is some uncertainty on moisture still in the models, will continue to monitor trends. However, will certainly be keeping a close eye for potential fire weather headlines given the higher confidence for lower humidity across western Nebraska.

A cold front tracks through the region Monday night, bringing a shift to northerly winds and slightly cooler temperatures. Highs on Tuesday are expected to be around the upper 70s to lower 80s. This still remains above average for this time of year. However, by Wednesday, temperatures rebound back to the mid to upper 80s, remaining so through the end of the week. Comparing these highs to local climatology, these temperatures are generally above the 90th percentile for early to mid May, but still below record highs.

With these unseasonably warm temperatures, expect to see low relative humidity values through the end of the week as well, generally at or below 20 percent. Also appears that gusty winds will be possible each day through the end of the week. The combination of well above seasonal temperatures, low humidity, and gusty winds may lead to elevated to near critical fire weather conditions throughout the week. Highest confidence at this time would be Wednesday, when gusty conditions appear most likely. However, marginal wind gusts are expected nearly every day, so will keep a close eye on forecast trends as we approach next week.

AVIATION /06Z TAFS THROUGH 06Z SATURDAY/

Issued at 1230 AM CDT Fri May 8 2026

VFR conditions are expected to prevail across western and north central Nebraka throughout the effective TAF period. Winds remain mostly light and variable overnight, with mid to high cloud cover expected through the night. By early morning, cloud cover is expected to break, with cumulus developing throughout the morning and afternoon. Winds begin to pick up out of the northwest, becoming gusty by mid morning. Strongest wind gusts are expected across the Sandhills and northern Nebraska, with peak gusts between 25 to 30 knots. Winds decrease by the evening, as an inversion develops, bringing a return to light and variable winds.
