Issued at 216 AM CST Mon Nov 17 2025 Today through Tuesday... Light southeasterly winds and patchy high clouds kept temperatures limited to the 30s and 40s overnight. An upper low will move out of the Wyoming/Colorado area into the Central Plains today. Strong warm air advection ahead of this approaching system will continue to bring increasing cloud cover to the region today, as moisture moves in. Low level dryness may prove difficult to overcome initially, but chances for light rain and drizzle reaching the surface will increase throughout the day. As rain moves out late tonight, totals will likely remain under 0.10", with highest amounts limited to northeast Nebraska and western Iowa, along and north of a line from Columbus, to Omaha, to Red Oak, IA. In addition to the rain, southeasterly winds will increase through the day, with speeds up to 20-35 mph possible. Temperatures will be boosted with the warm southerly flow, yet still limited by the persistent cloud cover, leaving afternoon highs ranging from the upper 40s over northeast Nebraska to close to 60 near the Nebraska/Kansas border. Winds will weaken by early Tuesday morning, as they turn to the north behind the passing cold front. A few sprinkles could persist into the early morning hours on the back side of the low, however a dry forecast is expected to prevail for the vast majority of the day. Temperatures will again range from the upper 40s over northeast Nebraska, to the 50s over southeast Nebraska and southwest Iowa. Overnight lows will hover just above freezing, in the mid to upper 30s both Monday and Tuesday nights. Wednesday and Beyond... Dry weather prevails through Wednesday and most of Thursday, ahead of the next approaching low pressure system. A few showers could sneak into southeast Nebraska and southwest Iowa Thursday, before precipitation begins to overspread the forecast area from the south. While rain will likely be primary precipitation type late this week and into the weekend, a few ensemble members continue to hint at light snow mixing in on the backside of the system Friday night. Dry weather returns for the remainder of the weekend into early next week. Daytime highs will remain in the 50s, however nights will dip toward freezing, beginning Friday night and continuing through the end of the forecast period. && .AVIATION /18Z TAFS THROUGH 18Z TUESDAY/... Issued at 1156 AM CST Mon Nov 17 2025 MVFR cigs have expanded eastward to around KFET, currently impacting KOFK and KLNK. Models keep the MVFR cigs west of KOMA, but seeing current trends continuing to expand eastward closer toward KOMA, went ahead and put in cigs around FL030 at KOMA starting around 20Z. MVFR cigs will hold over the area until around 00-01Z at KOMA and KLNK, and closer to 04Z at KOFK. A cold front will move across the area shifting winds to northwesterly overnight and bringing MVFR cigs back into northeast Nebraska and KOFK early Tuesday. As of right now there`s about a 20% chance MVFR cigs make it as far south as KOMA and KLNK around 12Z, so keeping these out of the TAFs. Expect MVFR cigs to hold through the remainder of the TAF period over northeast Nebraska while VFR cigs hold at KOMA and KLNK with winds staying out of the northwest. && .OAX WATCHES/WARNINGS/ADVISORIES...
