Today is the day of big changes across the TV9 viewing area, including some changes to the forecast. We are still expecting the arrival of a very cold airmass to being today, but it appears increasingly likely that ingredients for accumulating snow will now accompany this transition. Most of eastern Iowa will see some snow, with 2 to 4 inches possible in a band between US Highway 20 and US Highway 34, which runs from Ottumwa to Mount Pleasant. Surrounding that area, a trace to 2 inches is possible. Winds will be strong and the snow somewhat fluffy, so blowing and drifting will be a concern during the day on Monday. Snow begins late this evening, likely after 7 pm, and lasts as late as Noon on Monday in the south. After that, record cold remains possible during the early week, with gradual warming.
