Thursday starts a snowy a very cold stretch that continues through the weekend. 


Temperatures fall overnight Wednesday and continue falling through Thursday. Temperatures will be in the upper teens just after midnight, falling to the lower teens by afternoon and single digits by Friday morning ( Fig 1).

The arctic air blowing across the open lake will ramp up lake effect snow by 3 a.m. Bands of snow continue through Thursday evening. The main question will be where the main band of snow sets-up (Fig 2). The latest model runs show the main band wavering east to west, holding over western St. Joseph county, then fading back to the east. 

In classic lake effect fashion, amounts will vary greatly across the area, most should plan for 2" to 4" with 4" to 6" possible under the heaviest bands. 

Stay tuned as Saturday could bring a similar round of snow and frigid temperatures.
