DETROIT, MI — Tuesday is shaping up to be a day worth watching closely across a broad stretch of the eastern United States.

What the Current Outlook Is Showing
The latest severe weather outlook map is painting a two-tier risk zone across the eastern half of the country for Tuesday’s storm potential. Two distinct shaded areas tell the geographic story of this setup.
The yellow zone — representing the higher-confidence portion of the severe weather risk — covers the core of the threat area. This zone stretches from southern Illinois and Missouri northeastward through Indiana, Ohio and into southern Michigan and western Pennsylvania. This is where organized severe thunderstorm development is considered most likely during the Tuesday afternoon and evening window if the atmosphere cooperates.
The brown zone — a broader, more uncertain severe weather area — extends the potential risk outward in all directions from that yellow core. It reaches from Arkansas and Missouri in the southwest all the way northeast through Michigan’s Lower Peninsula, northern Ohio, Pennsylvania and into New York.
