Precipitation, mainly as rain, will move into central SD Monday afternoon and move east through the night before turning into some snowfall Tuesday morning. The highest liquid totals are expected over eastern SD, however the area of highest totals could shift depending on if the system is more to the north or south. Additionally, areas of heavier rain Monday night could see some sleet occurring for a bit.
While the majority of the precipitation from Monday's system will fall as rain, there will be a transition over to snow sometime early Tuesday morning, though there is uncertainty in how late Monday night into early Tuesday morning this change over will be. Current snowfall totals are showing from a trace to a tenth of an inch of snow accumulating mainly in the Sisseton Hills and along the eastern side of the Prairie Coteau, however if the band of snow sets up just right, then up to an inch of snow could fall over areas of higher elevation.
