All week long on Alabama Public Radio, we’ve been looking back at the tornado outbreak on April 27, 2011. The storms impacted homeowners and businesses, and you’ve heard from many of them during our coverage.

Now we’ll look ahead. For the past two months, dozens of scientists have been conducting groundbreaking research on tornadoes and severe weather right here in Alabama.

APR’s Alex AuBuchon has more on the impact that research could have on meteorologists' understanding of severe weather and forecasters’ ability to predict it.

The Tennessee Riverkeeper has announced its intention to sue several entities including chemical manufacturer 3M over pollution in the Wheeler Reservoir.

The riverkeeper plans to sue 3M as well as BFI Waste Systems of Alabama, Decatur Utilities and the City of Decatur. They allege those groups are responsible for contaminating the waterway with perfluorinated compounds, or PFCs. PFCs tend to accumulate in the bodies of humans and animals, and exposure has been linked to diseases like cancer, thyroid disease and ulcerative colitis.
