KEY MESSAGES

- Temperatures will continue to remain on the warm side this weekend into early next week, especially for areas along and west of Highway 83.

- Elevated fire weather concerns remain across western Nebraska, especially given the expected hot and dry conditions. Winds will continue to be the determining factor.

- Confidence continues to build in a pattern shift towards cooler, wetter weather starting mid week.

SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 238 PM CDT Sat Aug 8 2026

Upper level ridging is observed across the western United States, with the main core of the jet stream remaining across the Dakotas. Below the ridge, an area of warm air advection aloft is noted tracking across the Plains. This push of warmer temperatures aloft will not only lead to warmer surface temperatures, but also provides a solid cap on the environment, as seen in the 18z KLBF sounding. However, a fair amount of instability remains above the cap, and is expected to remain through the evening as the boundary layer decouples. Much like last night, a low level jet is expected to develop across the Plains. However, this jet is expected to push further north, firing convection across South Dakota late this evening into the overnight hours. With the marginal forcing, cannot completely rule out that a few elevated storms develop across northern portions of Nebraska, but have generally limited this to slight chance PoPs in the forecast. Should be worth mentioning that with the strength of the cap, expecting any convection that could develop will be above the cap, greatly limiting a severe threat this evening into the night. However, as the stronger storms across South Dakota track east-southeast tonight, may see a few of the stronger cells clip portions of north central Nebraska, generally areas north of the Niobrara River. These cells may pose a better wind risk, especially if more linear convection occurs over South Dakota, however, probabilities remain on the lower side at this time. For what it's worth, the Storm Prediction Center has greatly trimmed the Marginal Risk for today and tonight, as well as early morning across the North Platte CWA. In fact, the main concern would be (as previously mentioned) any of the stronger cells in South Dakota potentially clipping portions of north central Nebraska.

Further to the south, may see some additional fog development in the predawn hours, lasting into the early morning hours. The main areas of concern remain in lower lying regions and river valleys across southwest and central Nebraska. Overnight, fairly light winds are expected, with dewpoints remaining in the 60s. At this time, not thinking a Dense Fog Advisory will be needed, but may see some patchy fog, especially along the river valleys early morning, which may impede visibility.

For Sunday, expecting a fairly hot and dry day across the region. While highs are expected to reach the 90s across most of the region, the warmest temperatures are expected west of Highway 83, where stronger warm air advection is expected. For areas west of Highway 83, expecting that highs will push into the mid to upper 90s both Sunday and Monday. Latest guidance has trended these highs just a few degrees cooler, now keeping highs mostly below 100. In fact, even heat indices are expected to remain below 100, with the best chances of seeing anything above 100 limited to far southwest Nebraska. These temperatures, while warm, are only around 10 degrees above average for early to mid August, with typical highs right around 87 to 89.

However, this heat is also expected to be accompanied by fairly dry conditions. This may bring greater concern for areas across western Nebraska, mainly west of Highway 61, where the latest drought monitor still shows severe to extreme drought conditions. These relatively hot and dry conditions may drive at least some elevated fire weather concerns into early next week. However, have seen a slight trend towards slightly higher humidity during the afternoon, with areas west of Highway 61 expected to remain just above 25 percent humidity. With this slightly better humidity, winds will be the primary factor in whether or not elevated concerns are achieved the next few days. Expecting mostly easterly winds on Sunday, with gusts up to 25 mph, and more southeasterly gusts on Monday, with peak gusts again around 25 mph.

LONG TERM /TUESDAY THROUGH FRIDAY/

Issued at 238 PM CDT Sat Aug 8 2026

Conditions are expected to remain warm on Tuesday, and much like the previous days, expecting warmest conditions will remain along and west of Highway 83, with highs pushing into the mid to upper 90s. Will also be keeping an eye out for potential elevated fire weather concerns west of Highway 61 again, as humidity drops around 25 percent in the afternoon with gusty easterly winds, up to 25 mph.

By mid week, guidance suggests an upper level trough attempts to track over the western United States, slightly pushing the ridge to the west. This signal continues to be noted with the latest forecast cycles, continuing to build confidence in the pattern shift. However, there is still a bit of uncertainty in the amplitude of the various upper level features, so there may still be some slight refinement on timing over the next few forecast cycles as guidance comes into consensus. Regardless, this is expected to usher in a more active upper level pattern, increasing chances of precipitation Wednesday onward. Ensemble guidance suggests fairly strong chances for at least measureable precipitation, with the European ensembles remaining more optimistic than the GEFS solutions on precipitation chances and amounts. Along with the increasing precipitation potential, expecting to see a cooling pattern by mid week as well. In fact, this trend continues to suggest highs that may be around 10 to 15 degrees below average to end the week, with highs dropping into the 70s.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1226 PM CDT Sat Aug 8 2026

VFR conditions are expected to prevail across western and north central Nebraska throughout most of the effective TAF period. Some lingering low stratus is observed over southwest Nebraska this afternoon, continuing to erode. Through the afternoon and evening, mostly clear skies are expected, with southerly gusty winds across the region. Tonight, another round of showers and thunderstorms may attempt to form along northern Nebraska, with low confidence in any impact to the KVTN terminal. Further to the south, additional fog may develop in low lying regions and river valleys, potentially bringing fog into KLBF in the predawn and early morning hours.
