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 /12Z TAFS THROUGH 12Z TUESDAY/...
