We may continue to see a few lingering storms along the secondary front associated with the upper-level trough overnight across southeast Nebraska and southwest Iowa. These storms are elevated in nature and won't be tapping into the enhanced low- level shear which should keep severe potential very low with these storms overnight. CAMs clear them mostly out of our area by 1AM, with a few lingering showers possible across far southeast Nebraska into early Friday morning.

With storms clearing out of the area, we look ahead to Friday with higher pressure sliding across the region. This will lead to clearer skies, but the stationary front to our south will be blocking any tap into the warmer air to our south. This will keep temperatures cooler under the High with daytime high temperatures only peaking in the upper 50s.

As this High starts to clear to the east Friday night into Saturday, we see the cooler air mass get picked up and pushed east on the northern fringe of the Subtropical Ridge over the Southeast, leading to enhanced southerly flow across the Great Plains. This will bring temperatures up as well as bring back in moisture from the Gulf. With the return of warm, moist, unstable air to the region, as well as volatile southwesterly flow ejecting shortwaves through ahead of an approaching trough, we'll see shower and thunderstorms return to the forecast on Saturday. These chances hold through most of the day with a marginal risk for severe storms (level 1 of 5), main threats being large hail and strong winds.

Rain chances lessen, but don't completely clear on Sunday depending on how quickly the upper-level trough can push the cold front through Saturday night into Sunday. While the primary deterministic models clear us out by Sunday afternoon, some of the ensembles hold onto some lingering showers through Sunday evening. Ahead of the cold front on Sunday we do continue to see strong southerly flow bringing temperatures Sunday afternoon up into the mid 70s to low 80s.

Next Week...

We're watching potential for a couple rounds of severe storms Monday and Tuesday next week as we continue to tap into the warm, moist, unstable air mass from the Gulf as a couple more shortwaves eject out of the deep upper-level trough over the West Coast. While details remain hazy this far out, there does appear to be a broad area of shear and instability forecast to set up ahead of these system Monday into Tuesday, leading to potential for all hazards including tornadoes, hail, and damaging winds across a good portion of the Great Plains from central Texas north into eastern Nebraska northeast toward the Great Lakes. The severe threat shifts off to the east on Wednesday as the deep upper-level trough over the West Coast finally kicks free and moves through our area. While we will continue to see chances for rain on Wednesday, the low-level jet which has been advecting in the unstable environment shifts off to the east leading to lower chances for anything severe.

The upper-level pattern continues to remain unsettled going into the latter half of next week. Though temperatures trend back closer to normal, we'll continue to see additional low chances for showers and storms through the end of the week.

AVIATION /00Z TAFS THROUGH 00Z SATURDAY/

Issued at 555 PM CDT Thu Apr 9 2026

Showers and storms are staying well south of KOFK this evening, leaving this site VFR overnight into Friday. Storms will be moving out of KOMA mostly by 01Z with a few scattered showers lingering for a couple more hours. A band of MVFR cigs will slide south into KOMA around 01Z and make it down to KLNK around 01-02Z this evening, expected to linger for a few hours before clearing around 04Z. Meanwhile winds remain mainly out of the north around 10KT. Once low clouds clear, expect VFR conditions to prevail through the rest of the TAF period with winds shifting to the northeast later in the morning on Friday.
