KEY MESSAGES

- Gusty northwest winds persist through the afternoon, tapering off this evening. Wind gusts of 25 to 35 mph are expected.

- Cooler air arrives tomorrow as a cold front drops into the region. Expect highs in the 40s through at least the weekend. Morning lows will fall into the 20s on Thursday and Friday.

- A storm system expected to move across Oklahoma and Texas may bring a little precipitation to areas along the Kansas/Nebraska border on Sunday.

DISCUSSION

Issued at 113 PM CST Wed Nov 11 2026

The forecast period begins with northwest flow and a fairly tight pressure gradient over the Central High Plains, High Plains, and Great Plains. An amplifying ridge is in place over the western CONUS and a trough continues to dig southeast toward the Gulf Coast. Northwest winds continue to gust to around 25-35 mph through the afternoon, decreasing after dark. High temperatures this afternoon will top out about 5-10 degrees above normal, ranging from the mid to upper 50s along and north of a line from Tekamah to Creighton. Areas south of this line can expect to reach the low to mid-60s.

Heading into this evening/tonight, the low pressure system causing the tight pressure gradient over our area will shift east while an attendant cold front continues to slide southeast. A reinforcing cold front will drop into eastern Nebraska/western Iowa from the Dakotas. This will bring a shot of colder air to the region, impacting our temperatures for the next few days. By Thursday morning, low temperatures are expected to fall into the low to mid- 30s.

Thursday, the amplified ridge shifts east over the Rocky Mountains while the trough continues to deepen over the eastern CONUS and Deep South. Models are showing 850mb temperatures decreasing heading into the afternoon and evening hours. High temperatures for some areas may occur earlier in the day, as the colder air pushes into the region behind the cold front. Additionally, cloud cover may limit how much some areas may be able to warm through the day. Expect a chilly day with expected high temperatures struggling into the 40s for some locations.

Friday morning continues to look like the coldest morning of the fall season thus far for many areas. Widespread lows in the low to mid-20s are expected as people head out the door in the morning.

Our next chance for precipitation may occur late Saturday night/early Sunday morning through Sunday afternoon. Precipitation chances (20-30%) will be limited mainly to areas along the Kansas/Nebraska border. There is still considerable model uncertainty over the path of the storm system expected to move through. The ECMWF continues to attempt to maintain a low pressure system trekking across Oklahoma and norther Texas through the day Sunday. The GFS has the low becoming an open wave as it moves east. This system is expected to be able to tap into warm Gulf air, potentially bringing a little moisture into our area, although the better chances for precipitation will be mainly south in Kansas, Oklahoma, and Texas. Expected temperatures are showing lows Sunday morning in the mid-30s for areas that could potentially see precipitation and many models are showing rain potential, while a few show the possibility of some snow. One question to consider will be whether we will have any ice in the clouds as this system comes in. Looking at potential thermal profiles, there are some questions about whether we will have any ice in the clouds to be able to have a possibility of snow development. This will be something we'll have to monitor closely in the coming days.

The cooler weather will stick around through the start of next week, warming slightly by Monday as an upper ridge moves over the Midwest. Expect highs to be primarily in the 40s and lows in the 20s nd 30s.

AVIATION /00Z TAFS THROUGH 00Z FRIDAY/

Issued at 534 PM CST Wed Nov 11 2026

VFR conditions are observed at terminals this evening. A band of clouds now at 5,000 feet will stream in from the north over the next few hours. Expect ceilings to gradually lower to 2,000 to 4,000 feet at terminals: some guidance suggests we could see drops to MVFR, but confidence on any terminal seeing these reductions remains too low for inclusion into TAF at this time. Gusty winds subside over the next hour or two, and remain from the north at 10 kts or less.
