KEY MESSAGES

- Elevated to near-critical fire weather conditions appear possible each day Thursday and Friday across portions of west central Nebraska.

- Rain and thunderstorm chances return later in the day Thursday, favoring areas west of Highway 83. While widespread severe weather is not expected, a few storms may be capable of gusty winds and occasional lightning.

- Low to moderate confidence in showers and thunderstorms Saturday night into Sunday.

- Moderate confidence in a return to warmer, above normal temperatures by early next week.

SHORT TERM /THROUGH FRIDAY NIGHT/

Issued at 334 AM CDT Thu May 7 2026

Early this morning, southerly flow continues across much of western Nebraska. These winds should veer to more westerly, strengthening as they do. As the LLJ increases, downsloping flow coincident with warm air advection (WAA) will help stall any cooling overnight. This on top of increasing high level clouds may hamper any radiational cooling. The ongoing Freeze Warning will be left alone as sheltered areas may still manage to fall to around the 30-32F range though confidence in seeing a widespread freeze is fairly low.

Thursday/Thursday Night...the first warmer day will settle in across the region today. A mid-level disturbance will track along the lee of the northern Rockies through the day as a surface low takes shape across western Nebraska towards midday. Continued downsloping flow will promote warming and drying beneath h85 temperatures climbing into the 12-16C range. The result is afternoon highs climbing into the upper 60s to lower 70s, near to slightly above normal for early May. Short-term guidance hints at fairly reasonable mixing heights which causes some concern about winds potentially overachieving across the area. This is particularly concerning as a belt of stronger h7 flow crosses central Nebraska midday through early afternoon. Deterministic guidance suggests gusts should remain less than 20 mph but inspection of BUFKIT soundings suggests momentum transfer may manage to produce gusts closer to 25-30 mph. With the warmth and approach of drier mid-level air, afternoon humidity values should fall into the 15 to 25 percent range for all of the local forecast area. Should winds trend a little stronger through the late morning, fire weather headlines may be necessary. Later this afternoon, behind a Pacific front, a midlevel disturbance within a richer moisture environment will support scattered showers and thunderstorms. Forcing will largely be driving by an approaching shortwave with modest instability in place advertised as MUCAPE < 500 j/kg from the Wednesday evening HREF run. Forecast soundings do show surface based storms overtop a deeply mixed boundary layer, the prototypical inverted-v sounding. This suggests the potential for gusty outflow winds from any activity and extended HRRR/RAP raw output shows strong surface winds in vicinity of any activity. For now, believe any gusts would be sub-severe though speeds up to 50 mph cannot be ruled out. Otherwise, limited deep layer shear should preclude any other convective hazards with this activity. HREF probability matched mean QPF shows fairly widespread measurable rain but limited coverage of anything exceeding 0.10". As the boundary layer stabilizes with loss of daytime heating, instability will wane and activity should dissipate. Dry conditions are likely to return by daybreak on Friday, likely sooner for many locations. With remaining debris clouds and the improved moisture, low temperatures will remain on the milder side in the upper 30s to lower 40s.

Friday/Friday Night...dry conditions are expected across the area for the day. Behind departing shortwave trough, heights will begin to build early. Resulting subsidence will yield clearing skies and another day of mild temperatures. Following the passage of the frontal boundary from Thursday, temperatures aloft will only fall slightly before recovering again to the low to middle teens at h85. Breezy northwest winds are likely to persist much of the day as the area resides under strong mid-level flow. The Pacific airmass will support increased dew points early but dry air will again infiltrate the area. This will result in near to slightly above normal afternoon highs (upper 60s, middle 70s) and falling afternoon humidities. Uncertainties remain regarding how low minimum humidities fall and this is likely the limiting factor with regard to fire weather concerns. Deep mixing should again promote momentum transfers capable of 25 to 30 mph gusts but where the driest air sets up may limit overlap of strongest winds and critically low humidity. For now, the going forecast calls for humidity levels reaching around 20 percent with rather limited coverage of these values in Zone 209. Thus, no headlines will be issued with this package, but we'll continue to monitor closely. Expect another similar night with lows in the upper 30s to lower 40s beneath increasing clouds within the continued northwesterly flow.

LONG TERM /SATURDAY THROUGH WEDNESDAY/

Issued at 334 AM CDT Thu May 7 2026

An active start to the extended period is expected as an upper level trough digs south across the Rockies. This system will bring the next potential for showers and thunderstorms to the region. There will be some modest instability (CAPE near 550 J/kg, lapse rates around 6 C/km) across southwest Nebraska and into the Panhandle which may result in some stronger to briefly severe storms. Overall, not expecting the severe potential to be high as these storms will likely be embedded within the larger rain pattern. If a storm or two can become more isolated and discrete, there might be a better potential for some small hail or strong winds. Still, despite rain shower potential lasting much Saturday, QPF will be minimal with this system. Generally expecting under a tenth of an inch of precipitation throughout Saturday and Saturday evening.

Drier conditions return on Sunday as upper level ridging builds across the western US and strong surface pressure returns to the region. This drier pattern will remain in place through mid-week allowing for dry conditions to persist.

For temperatures, highs will remain in the upper 60s to mid 70s Saturday and Sunday. By early next week, warm air advection will push a much warmer airmass with 850 mb temperatures in the 20 to 26 C range out of the southwest US into the central Plains allowing highs to rise back into the 80s through early week. There is even a potential for locations to hit the low 90s on Monday across southwest Nebraska. Overnight lows will remain in the upper 30s to low 40s through Sunday night, but will rise back into the mid to upper 40s through Wednesday night as the warmer air settles into the region.

AVIATION /06Z TAFS THROUGH 06Z FRIDAY/

Issued at 1255 AM CDT Thu May 7 2026

VFR conditions will prevail through much of the next day. Some thunderstorms may develop late this afternoon across portions of southwest Nebraska. Confidence is fairly high in development, but there is low confidence in exact locations of impact. Isolated to scattered storms will continue through the evening impacting KLBF with brief reductions in visibility as well as gusty and erratic winds. Conditions return to VFR shortly after Midnight CT.
