The Alberta Clipper expected to supply portions of Greater Lafayette with our first measurable snowfall of the season remains centralized over parts of western Wisconsin, but is already generating scattered snowfall over Northern Illinois.
The fast moving system will continue on its southeastward track during the overnight hours. The organized line of snowfall advancing ahead of its cold front will likely reach our northernmost counties after 3:00 A.M. ET.
The latest model data continues to downplay heavy accumulations for all but our northeastern counties. In fact, much of the region appears as though they will receive little more than a fraction of an inch.
The initial line of snow along with its associated cold front will pass to our east and out of our viewing area by 9:30 A.M. ET. This initial line represent all of the snow many of us will see throughout the event.
Once the cold front is safely tour east, strong northerly winds will settle in over the region; temperatures will drop and moisture will be pulled southward from Lake Michigan across our north-easternmost counties in the form of lake-effect snowfall.
Most of our western and southern counties will see below an inch of accumulation between now and Saturday afternoon. The heaviest areas of accumulation will be found among those of us who receive the lake-effect snow later in the day.
Portions of the northeastern quarter of the viewing area could see as much as two to four inches of snow by the time it’s all said and done late tomorrow evening.
Be safe and enjoy the snow!
