What a difference a month makes.

StormTRACKER meteorologist Jesse Ritka said rain since mid-August has made a big difference in the Upper Midwest and Northern Plains on the U.S. Drought Monitor.

That's especially the case on the southern side of the Red River Valley in parts of North Dakota, South Dakota and Minnesota, as well as into Iowa, Illinois and Wisconsin. Those areas have seen great improvement in soil moisture, she said.

While drought conditions have improved somewhat, the impact of the hot, dry summer remains. The U.S. Department of Agriculture on Wednesday, Sept. 8, announced feed transportation assistance for ranchers in drought areas.

Soil moisture percentile has started worsening again in much of the region, Ritka said, and there's isn't a lot of rain in the forecast for the coming weeks.
