Isaac set to bring much needed rain to Northern Illinois

As Isaac comes ashore south of New Orleans with 80mph wind tonight, it will begin its weakening phase. As that happens, it will also begin its 3 1/2 day trek toward Rockford. With a landfall in Louisiana and little/no steering wind until it reaches Oklahoma, I believe this is far enough west we’ll get rain from it. The storm will likely be a depression by Wednesday afternoon and just a remnant low pressure by Thursday. But it will still bring some drought-busting rain to Oklahoma, Missouri, and Illinois. Rainfall amounts from our models are still all over the place but the driest model gives Rockford more than a half inch of rain! There’s even a chance of some flash flooding in Central Illinois as Isaac moves toward Northern Indiana.

Because this will be taking place on Labor Day Weekend, it appears the timing of the rain (and gusty 40mph wind) will be from Saturday morning to Sunday afternoon. -Eric
