Periodic thunderstorm chances and above-normal temperatures continue into next week. && .DISCUSSION... Issued at 1059 PM CDT Thu Aug 27 2026 A damaging thunderstorm complex is ongoing across southern Nebraska and northern Kansas late this evening. High cirrus from this system 200 miles to our west may partially obscure tonight`s lunar eclipse. Beyond this, there is a low chance for showers or an isolated thunderstorm tonight, but most remain dry. Temperatures fall into the low 60s by Friday morning with quiet weather conditions. Our next weather system begins to take shape to our west during Friday afternoon. This will cause south winds to slowly increase throughout the day as temperatures warm into the mid 80s. A shortwave trough glances the area to the north late Friday night into early Saturday. The better thunderstorm chances remain focused north of the area, but scattered showers or thunderstorms may dip into northeast Nebraska and western Iowa as this system passes. This weekend sees temperatures build. A combination of the Southwest ridge and troughing to the north will not only fuel warmer temperatures, but also result in breezy conditions. It is expected that temperatures on Saturday and Sunday push into the low to mid 90s across most of the area. It will be humid as well, resulting in heat index values approaching 100. With any weather disturbances passing far to the north of the area and hot temperatures in place, thunderstorm chances are unlikely. Even if thunderstorms approach the area, increasing stability under the ridge should limit their persistence. Heading into next week, the ridge will begin to flatten. This helps lower temperatures back into the upper 80s to low 90s, though this remains above normal. With more zonal upper-level winds returning to the northern Plains, periodic thunderstorm chances return to the forecast. The best chance for thunderstorms will primarily be focused during the evening and overnight hours. && .AVIATION /06Z TAFS THROUGH 06Z SATURDAY/... Issued at 1221 AM CDT Fri Aug 28 2026 As the storm cluster continues south into Kansas to our west, high clouds will clear north to south overnight tonight.
