The unusually warm weather in northern Illinois is starting to take its toll on crops, causing some DeKalb County farmers to worry about yields.

The county is short about six inches of rain this year compared to average rainfall amounts, said Gilbert Sebenste, meteorologist for Northern Illinois University. With only 1.83 inches of rainfall so far in June, precipitation in the county is down 25 percent to 30 percent just this month.

Mariam Wassmann, DeKalb County Farm Bureau director of information, said although the weather is dry, crops seem to be faring well.
