Forecasters at WSAW in Wausau told central and north-central Wisconsin viewers on Sunday, September 13, 2026, that the weekend would end breezy and cool, with an early chance of frost in the region before a change in the pattern. The outlook called for a few dry days with seasonable temperatures into the middle of September, followed by the possibility of rain and storms late Monday. The frost potential is notable in mid-September because it can damage late-season gardens and sensitive crops. The cool air mass over the Upper Midwest contrasted with unseasonable warmth further south in the United States on the same day, illustrating a sharply split national temperature pattern. Local forecasters advised residents to cover or bring in sensitive plants and suggested the dry stretch would be suitable for yard work. The station's First Alert Weather team issued the guidance in its regular Sunday forecast update.
