The National Weather Service says large parts of rural Missouri and Illinois had between three-to-five inches of rainfall this weekend.
In St. Louis, Oakville received three and a half inches of rain, the most in the metropolitan area. But National Weather Service Meteorologist Jayson Gosselin said it will take much more rain to snap this summer's historic drought.
Drought-stricken Missouri is preparing for what has been an unusual occurrence this summer - a couple of rainy days. Forecasters expect remnants of tropical storm Isaac to reach Missouri on Friday, with rain spreading over southern, central and eastern portions.
The National Weather Service says the St. Louis region could get 3 to 5 inches. Soaking rains are expected to help alleviate Missouri's drought but not break it. More than 97 percent of the state is now listed in the two most severe categories of drought.
Officials with Ameren say they are closely monitoring Hurricane Isaac's progress now that it has made land fall. Projections from the National Weather Service indicate the remnants of the storm could pass over Missouri and Illinois this weekend.
Kevin Anders, Ameren Missouri's manager of distribution services, says that could mean a lot of rain and - potentially - some high winds or tornadoes.
