Mix Today; A Look Ahead

SnowCrystals.com
A mix will continue to pass through the area as a large blizzard attacks northern Wisconsin and Minnesota. Below is the NWS snow accumulation forecast for Sunday.

Extreme SE Wisconsin will see all rain, with no snow accumulations. As you move farther north, you can see accumulations of 4-6" in central Wisconsin. The Green Bay/ Detroit Sunday night game will likely be a snow game (should be a good game). NW Wisconsin will receive the heaviest accumulations, with amounts possibly exceeding a foot.

The soundings are showing cooler profiles, so advisories and watches are extended farther south. Even if you aren't under a watch, you still need to drive slowly on the roads, as a mix can create very slippery conditions.

A Look At the Week Ahead

After the Sunday system finally passes through, you can expect dry conditions for several days. Highs will struggle to reach the mid 30s due to cold air advection. Depending on how much snow you receive this weekend, snow covers could also assist in creating cooler temperatures this week. 

The next system will enter the region next weekend. As with any system nearly one week out, there is much uncertainty with this storm. Many models are showing mostly rain. The latest GFS, however, trended the storm out of the area, leaving us dry for Saturday. The Euro gives us rain, as do most models.

As I said before, there is much uncertainty with this storm, but most of the models are showing rain. We will have to watch the system as it is very likely that the models will bounce back and forth over the next week. 

Thanks for reading the update!
