Issued at 1021 PM CST Wed Nov 4 2026 Tonight through Friday: Satellite imagery this evening shows the larger weather-making trough to our east continue to shift eastward while lift associated with it joining a shortwave entering the Central Plains from the Front Range of the Rockies. The 00z OAX observed sounding features a shallow boundary layer with decently steep lapse rates -- to the point where they`re contributing to some sprinkle chances and dots on the windshield for many this evening. Those chance increase as the cloud depth increases, with nighttime RGB imagery showing that the best lift is gradually pivoting southward from SD/MN. Temperatures turn chilly tonight as those sprinkles and areas of drizzle move through, with most locations having a 10-20% chance at best to see something measurable. Just off the deck, winds are swift with a few gusts of 30+ kts sneaking through the inversion already this evening. Those speeds certainly won`t be reached regularly, but we`ve given a bit of a nudge upward in wind speeds to match through the morning hours tomorrow. By sunrise, the low-end chances for a sprinkle or two will still be lingering across southeast Nebraska, pointing into Iowa before receding to the ENE. Cloud cover will still linger if forecast soundings are to be believed, making for continued cool and dreary days that end up on the dry side for us. Forecast highs could see a bit of a dip compared to what we have in there if the cloud cover is thick enough, and overnight lows could stay a bit warmer as well. The next aspect of the forecast to check out would be those overnight lows Thursday night heading into Friday, specifically the likelihood of reaching freezing or below. Comparing the NBM`s chances of hitting freezing against the larger EPS/NAEFS members, the influence of the cloud coverage is being undersold and you`ll have to travel a bit farther to the northwest to hit freezing (with better than 50% odds starting along a line from Columbus to Wayne. Areas to the southeast will have to wait until Friday night into Saturday morning to see a shot at freezing, as widespread lows close to 30 degrees area forecast. Double check outdoor hoses and plants to minimize any damage, we`re pretty behind in terms of the cold, I`d bet there are plenty of sprinklers/watering hoses that still need to be put away/winterized. Saturday and Beyond: After a chilly morning, the busier mid/upper pattern that has been overhead will begin turning a bit warmer as mid/upper ridging builds in from the northwest. Clearing skies will work with the building thermal ridge to the west to help us reach back into the 50s Saturday and into the 60s Sunday, making for an excellent weekend to enjoy any fall activity that the heart desires. That warming carries forward one more day into the upcoming work week, with highs reaching near 70 near the KS border, cooling into the middle of next week as the upper pattern returns to zonal flow. Dry conditions may carry us through the remainder of the week as well, with model guidance showing little to stir precipitation chances and a nod towards seasonably warm temperatures. && .AVIATION /06Z TAFS THROUGH 06Z FRIDAY/... Issued at 1144 PM CST Wed Nov 4 2026 Stratus with cigs around 2500 ft blanket areas north and east of KLNK this evening. KOFK and KLNK will stay on the western fringe of MVFR stratus overnight, KLNK staying more just west of the clouds while KOFK is in early, seeing low cigs clear eastward around 09Z. KOMA will be solidly socked in with cigs even expected to lower to 1500 ft by 10Z. Occasional drizzle briefly lowering visibility. Winds remain out of the northwest, occasionally gusting to 20-25kt, but mostly around 12-15kt. We see another push of lower clouds southward Thursday morning, moving into KOFK around 15Z, with cigs around 1500 ft. These once again may or may not make it into KLNK by 17Z, so put SCT in the TAFs. Will still be just on the western edge. KOMA stays under low clouds through Thursday morning, lifting to 2500 ft around 17Z with the arrival of the weak boundary. We see KOFK clear from the low clouds by 20Z, with KOMA clearing closer to 22Z. We`ll still see lingering cigs around 10,000-20,000 ft into the evening, but should remain VFR. There is some indication we could see low clouds return Thursday night, but confidence is too low at this time to include in the TAFs (20% chance). && .OAX WATCHES/WARNINGS/ADVISORIES... NE...None.
