ST. LOUIS (AP) — Growers in key farm states punished by the nation’s worst drought in two generations welcomed recent rains that at least for a time soaked their parched crops and eased the dryness. But with Hurricane Isaac’s remnants crawling their way, some farmers wonder whether too much relief is on the horizon.

Forecasters expect Isaac, which since making landfall Monday on the Gulf Coast has been downgraded to a tropical storm, could slide into Missouri, Illinois, Indiana, Iowa and Ohio as early as Friday, dumping as much as 12 inches of rain on the region.
