Two storm systems are making their presence felt in various ways as they impact the nation this week.

Participants: Rod Bain and USDA meteorologist Brad Rippey.

Transcript

Two weather systems are being observed by weather watchers like USDA meteorologist Brad Rippey through the week.

The first, what Rippey described as the more powerful of the two, parked itself early this week across the middle Mississippi Valley into the Great Lakes region.

It's a very large and slow moving system.

We have already seen considerable weather hazards associated with this storm, including severe weather outbreaks Monday and Tuesday.

The good news as we move into midweek and beyond, that severe weather threat will end fairly abruptly.

Later in the week, cold is expected to be left in the wake of the early week storm.

There is some concern that we could see some frost and near freezing temperatures extending all the way southward into the Tennessee Valley and the southern Appalachians.

With blooming fruit trees and heading winter wheat vulnerable to freeze, a second system is expected to bring beneficial moisture late week from the west to the Great Plains.
