STRONG WEEKEND STORM FOR THE MIDWEST:
The second major storm in 4 days is expected to bring a wide variety of weather back to the Midwest this weekend. Currently advisories for winter weather are in effect over this part of the upper Midwest.
As with the previous system, most of the precipitation with this disturbance in my area will come down as rain. However, by Sunday as the upper air low passes over the region it will drag a pocket of cold air aloft with it. That results in a window of 6-8 hours Sunday where there will be enough cold air and instability for snow showers.
The best forcing will be well to the north and that is where the heavier snow accumulations will be (Minnesota, Wisconsin, and northern Iowa). Since precipitation is going to be showery in nature in my area, coverage is going to be spotty, meaning pockets or bands of snow up to an inch could fall. Other areas not far away might see only a light dusting. As it stands now, I would plan on minor accumulations. Worst case an inch, best case a small dusting. The exception would be near and north of HWY 20 where there could be some isolated 1-2" amounts. Due to recent mild temperatures, some of the snow might have a tough time sticking to roads unless it's a quick heavy burst.
Here are the latest snowfall forecasts:
