The remnants of Hurricane Isaac dumped heavy rain on some key Midwest farming states that dramatically lessened the drought there, but conditions worsened in two of the nation's biggest corn producers, Iowa and Nebraska, which missed out on the badly needed moisture, according to a drought report released Thursday.
