High snowfall rates of 1 to 2 inches per hour may occur over a 1 to 3 hour time window in some areas which would lead to travel conditions quickly deteriorating and becoming treacherous. There is the potential for a moderate to even a heavy band of snow to set up across parts of the area and thundersnow may occur. Currently the most favored area for a heavier band appears to be somewhere from the Boone to Ames northwards towards Fort Dodge areas then northeastward towards Mason City and Waverly. Will continue to monitor that situation. The winds will become gusty at times today with gusts up to around 35-40 mph. Blowing snow is not expected to be a big impact due to the heavy and wet nature of the snow. Warmer air will be arriving from south to north today and tonight. Therefore, the snow will gradually transition to rain in central Iowa by late morning to midday. Stay tuned to continued updates on this impactful winter weather.
