706 FXUS63 KOAX 200832 AFDOAX Area Forecast Discussion National Weather Service Omaha/Valley NE 232 AM CST Thu Nov 20 2025 .KEY MESSAGES... - Another round of fog/drizzle is expected overnight, with visibilities dropping to near one mile after 2 AM. - Another storm system will move into the region Friday, bringing a 20-60% chance for rain across southeast Nebraska and far southern Iowa. - Mild, dry weather returns over the weekend before a third system arrives on Monday. - Thanksgiving temperatures look slightly cooler than normal for this time of year (around 45 degrees for Omaha). && .DISCUSSION... Issued at 221 AM CST Thu Nov 20 2025 Today... Winds began to shift to the north overnight, as a cold front moved in from the northeast. Radiational cooling enhanced by clear skies ahead of the front allowed for the development of patchy fog early last night. Another area of fog developed behind the front. By 2 AM the front remained draped from Neligh, NE to Yankton, SD. Visibilities ranged from a quarter to 5 miles with temperatures in the 30s and low 40s. Lower visibilities are expected to continue to spread southeast with the passing front through the early morning hours. The rising sun will struggle to erode fog this morning. Temperatures will vary based on how much sunlight is allowed to reach the surface through the decreasing cloud cover. Overall, highs will generally top out in the low to mid 50s. Thursday night through Friday... Fog will likely redevelop tonight, as temperatures dip into the mid 30s and low 40s. A low pressure system will move out of the Four Corners region and into Central Kansas tonight, with precipitation overspreading the southern Plains. A few showers could sneak into southeast Nebraska and far southwest Iowa late this evening and overnight, with rain chances continuing to overspread the southern half of the forecast area on Friday. Temperatures will remain cooler than the previous few days, topping out in the upper 40s and low 50s Friday afternoon. Saturday and Beyond... Rain chances will diminish Friday evening as the low shifts east and subtle upper ridging builds in for the weekend. Temperatures will rebound back into the upper 50s and low 60s on both Saturday and Sunday. Another low will move out of the southwestern CONUS, and into the Central Plains on Monday. This will bring another chance for showers early next week, with the best chance once again across the southern half of the forecast area on Monday. A clipper system will drop southeast out of Canada by mid week bringing noticeably cooler temperatures to the region just in time for the Thanksgiving holiday. While the track of this system remains uncertain at this time, if it drifts far enough south as a few of the longer range models indicate, we could see a couple snow flakes late next week. && .AVIATION /06Z TAFS THROUGH 06Z FRIDAY/... Issued at 1106 PM CST Wed Nov 19 2025 Fog will be the main concern at the terminals through 15Z. Fog has developed to the east and west of the terminals, reported at KJYR, KMLE, K4V9, KTQE, and KOFF. Fog will continue to expand in coverage over the next couple of hours, bringing visibility down to MVFR to IFR levels, which will impact terminals. Patchy dense fog may be possible in some locations; however, confidence in this occurring at the terminals is uncertain at this time, so this was held out of prevailing conditions. The fog should burn off around 15-18Z. North winds will be fairly light through the day, turning to the north- northeast heading into the afternoon at KOFK and KOMA. Ceilings should improve to VFR heading into the afternoon. Toward the end of the forecast period, there will be a chance of a few rain showers at KLNK, with coverage increasing northward to include KOMA overnight. && .OAX WATCHES/WARNINGS/ADVISORIES...
