There is potential for a winter storm system to occur in the North Plains and into the Midwest.
On April 14, a strong low pressure system will slide across the nation’s midsection. This low pressure system will be producing abundant precipitation. Just for show, an additional trough will be pulled by the low pressure system to create more precipitation.
That low pressure system will pull down the jet stream to open up a flow of cold Canadian air into the North Plains. That said, there is now a chance for abundant snowfall to occur. According to the NAM, potentially over a foot of snow could occur.
On the east side of the precipitation will be more of a rain situation, affecting cities such as Chicago, Madison and potentially even St. Louis.
The low will then push into Illinois. High pressures will collapse southward and keep the cold air around the North Plains.
So overall, there is a chance for a snowstorm in the North Plains and a rain event in the Great Lakes.
