An upper-level trough digging across the central U.S. will bring chances for heavy precipitation and depending on where the freezing line sets up, heavy snow will be possible.  Here is the latest forecast.

Upper-Level Set-Up

A large dip in the upper-level winds will allow cold air to drive south out of Canada for the end of the week and into the weekend.  This cold air will be the big factor in what areas could see some heavy snow or heavy rain.

Forecast

Here is the latest forecast for the developing surface low that will take over the forecast. The track shows it heading right towards the Great Lakes by Saturday.

Snow showers will begin in the Rockies and the Central Plains before moving into the Upper Mississippi Valley and the Midwest.  South of this energy will be the potential for heavy rain and even a few thunderstorms for states like Oklahoma, Texas, Arkansas, Missouri and Illinois.

Snowfall Forecast

The latest snowfall forecast is showing the heavy snow dropping over Iowa, Wisconsin and Michigan.  Any change in this forecast track could lead to the heavy snow being more north or more south, so keep checking with WeatherNation for all the latest updates on this forecast.
