DISCUSSION

A shortwave trough is currently pushing southeast from the northern Plains to the Great Lakes. This has led to numerous showers and thunderstorms across the high plains to the west of our area. Further to the east, showers and thunderstorms have begun to push into the area late this evening. The best rain chances are anticipated over southeast Nebraska with a few showers further north as we head through the overnight hours. With rain and clouds in the forecast tonight, temperatures remain mild through Thursday morning, only falling into the upper 50s to low 60s.

Thursday into Friday sees a largely stalled front from the aforementioned trough draped across the southern Plains up into the Midwest. Meanwhile, surface high pressure sets up to our north. This results in cooler temperatures on Thursday ranging from the low to mid 70s. Additional scattered showers and thunderstorms are forecast to develop, but with greatest forcing to our south and surface high pressure sitting to our north, coverage may be limited. Overall, rain chances are low (20-40% chance) for most of the area with slightly higher rain chances (50-70%) across far southeast Nebraska and far southwest Iowa. Temperatures remain mild with continued rain chances Thursday night into Friday morning with more upper 50s and low 60s. Showers and thunderstorms begin to push east of the region by Friday evening as temperatures warm slightly into the upper 70s.

A pattern shift arrives this weekend as mid- to upper-level ridging takes hold across the central and eastern CONUS. The heat holds off on Saturday with 80s currently expected, but the same can not be said on Sunday. Hot and humid weather overspreads the region by Sunday afternoon and this pattern should largely hold into at least early next week. Temperatures push well into 90s with dewpoints hovering in the upper 60s to low 70s. This combination results in heat indices in the low 100s for most of the area, likely approaching 105 for some. These temperatures will be closely monitored for potential heat products in future forecasts. Heading into next week, the worst of the heat subsides, but this only shaves a few degrees off our temperatures. The more substantial change will be the return of thunderstorm chances. As troughs round the periphery of the ridge, evening and overnight thunderstorm systems may develop to our west and push through portions of the area. It is too early to say how widespread these thunderstorms may be or if severe weather will be possible, but as a reminder severe weather season is not over just yet, so remain weather aware.

AVIATION /06Z TAFS THROUGH 06Z FRIDAY/

Issued at 1244 AM CDT Thu Jun 25 2026

VFR conditions favored through the period with ceilings generally around 5000-8000 ft. Winds will be out of the northwest to north to start the period, but will become northeasterly to easterly during the day Thursday, with speeds generally remaining under 10 kts. The main thing to watch will be shower and isolated storm potential throughout the period. LNK will likely see a few showers to start the period, though not expecting much impact outside of some brief wind shifts. Some guidance suggests additional development around 14-15Z and lingering through much of the rest of the period. Highest chances for impacts look to remain south of the TAF sites with several models suggesting most areas stay dry, but can't completely rule out some brief periods of TS and visibility reductions. For now, left out any mention, but trends will need to be monitored.
