A new storm has entered the Northern Tier, and will bring a light swath of snow to the Northern Plains, Great Lakes, Ohio Valley, and portions of the Central Plains.
On Sunday, there will be two separate areas of where snow will be falling: the Central Plains and the Northern Plains. A light snow will be moving through most of Missouri and into southern Iowa this afternoon. That batch of snow will then move into the western Ohio Valley, including most of Illinois and western Kentucky by the evening hours. By this time, the Arctic front, which is delivering snow to the Northern Plains today, will meet up with this separate piece of energy and will make for a more organized snow event Sunday night. Speaking of the Northern Plains, several hours of light snow behind this cold front is forecast this afternoon and evening. Snow showers are expected in the afternoon across portions of North Dakota, South Dakota, and into Nebraska. Meanwhile, a light snow will be falling across most of Minnesota.
Then Sunday night, a widespread light to moderate snow is forecast to continue in Minnesota while occurring in Wisconsin, Illinois, Indiana, and Michigan during at least a portion of the overnight. Further west, a thin line of snow, lasting for only a few hours, along the frontal boundary will move through central Montana, central Wyoming, northeastern Colorado, all of Nebraska, and all of Missouri. This band of snow will be bit heavier,and will drop a quick inch of two of snow.
As we get into Monday, our storm associated with this Arctic cold front will basically sit over the Great Lakes. Therefore, snow will persist across much of this region throughout the day. That includes Wisconsin and Michigan while snow clears out by the afternoon in Illinois. The snow will then clear out of Indiana as well as Ohio by the evening, so a snowy Monday is ahead there, as snow moves into western Pennsylvania and New York during the afternoon and persists into the overnight. Again, this snow will be light for the most part but travel issues are still expected. At least most schools will be closed due to Martin Luther King Day. Snow showers along a nearly stationary boundary may also continue from northeastern Colorado through southern Nebraska and into southern Missouri throughout much of the day Monday, especially in the morning. This is where an enhancement of snowfall totals are possible. By Monday evening, snow will begin to break out across portions of the Southern Plains as the front continues to plunge southward. Stay tuned for a story on this Southern snow event.
On Tuesday, spotty snow showers may continue across much of the Northeast before a line of snow develops behind the cold front and brings snow to portions of the I-95 corridor Tuesday evening into Tuesday night. This will be the same line of snow responsible for delivering a light snow to portions of the South.
Here’s our snowfall forecast through Monday evening:
