I'm keeping my eye on a fast moving Alberta Clipper that is expected to supply Greater Lafayette with our first measurable snowfall of the season!
The low, currently located along the Alberta / Saskatchewan border, will quickly migrate southeastward over the next 36 to 48 hours arriving in the Great Lakes and upper Midwest by tomorrow evening.
The latest model data suggests that the first of the snowfall should reach our northernmost counties around 12:00 A.M. ET early Saturday morning.
From there, the snow will dive southward and spread in across the viewing area. While we’ll see a period of sustained snowfall early Saturday morning, it appears as though the wave of snowfall along with its associated cold front will pass to our east by 7:00 A.M. ET or 8:00 A.M. ET.
Winds behind the passing cold front will shift northward. As a result, moisture from Lake Michigan will begin to flow southward off the lake and into our northeastern counties. Lake effect snowfall may linger in spots into the early afternoon.
Current projections indicate, by the time it’s all said and done, our viewing area will have been left with as little as a dusting of the white stuff in our southwestern counties and possibly as much as 3” of accumulation by the end of Saturday!
As for now, it appears as though the majority of Tippecanoe County (including Lafayette) will fall within the lower end of the 1”-2” projection. Though with some of the latest trends this morning, I wouldn’t be surprised to be measuring less than an inch come Sunday morning.
