A large part of Indiana is in severe to extreme drought, and prospects for rain through the weekend are weak, at best.

Storms in the Bloomington area southward on Sunday may have improved the situation somewhat there, but as a whole, the drought is worsening across the state.

"In portions of central Indiana immediately along and south of Interstate 70, little to no rainfall has occurred since June 1," the National Weather Service in Indianapolis said in a statement on its website.

Through Saturday, Indianapolis' year-to-date rainfall was about 7.5 inches below normal.

Recent extreme heat compounded the drought, with high temperatures averaging above 100 degrees over an eight-day period, the highest for any eight-day stretch since July 1936.

There are some rain chances late in the week, but it doesn't appear to be drought-busting rain.

"Looks like the best chance of rain will not be again until Saturday and Sunday," said Storm Team 6 meteorologist Todd Klaassen. "Even then, it will only be a few scattered showers and thunderstorms."

Agricultural interests are expected to take a big hit this year, with the possibility that corn and soybean crops could have their worst yields since 1988.
