SPRINGFIELD, IL – In Illinois, on any given week we could see blue skies, thunderstorms and torrential rainfall. The changing weather is second nature to many of us, but as the calendar flips from winter to spring, it is important to not become complacent about severe weather threats that exist in our state. As part of Severe Weather Preparedness Month, the Illinois Emergency Management Agency (IEMA) and the National Weather Service (NWS) have teamed up to publish a Severe Weather Preparedness Guide to help Illinoisans be better prepared when severe weather strikes.
