Steady snow overnight into Friday
The going forecast hasn’t changed too much for the total amounts of snow in the end. Some adjustments have been made for timing which appears to pull in the snow a tad later, between 8 PM south and 12 AM north.
Moderate intensity snow is a constant through sunrise before lightening up and moving out by late morning in the east. At times, there will be some heavier pockets overnight, especially in the areas near the state line and southward into Iowa.
Areas south of I90 and into Iowa get the slight favor to heavier snowfall totals. A widespread band of 3-6″ is likely here. Isolated spots may nose as high as 8″ in the end, although, the jumpy data has been inconsistent in pinning any one location as being favored for this. Just a bit less is likely north of the interstate, but still enough to be impactful. 2-5″ in these areas.
There is a brief opportunity at onset for some wintry mix including freezing rain, although this will be short-lived should it materialize at all. Snow is the dominant precip type.
A Winter Weather Advisory is in effect overnight through Friday morning. A few counties in north central Iowa have been upgraded to a Winter Storm Warning for the same timeframe. Winnebago, Hancock, Worth and Cerro Gordo counties are included in this. It is here that has the best chance at the higher end of the snowfall end up.
