Overview

• The National Weather Service issued severe thunderstorm warnings Sunday for multiple counties from Alabama through the Midwest to northern Pennsylvania, extending the region’s ongoing storm outbreak.
• Doppler radar guided short-duration alerts by pinpointing cells capable of gusts between 40 and 60 mph, with localized reports up to 80 mph in parts of the Upper Midwest.
• Warnings noted hail ranging from pea-size pellets to 1-inch quarter-diameter stones across affected counties in Michigan, Alabama and Oregon.
• Torrential rainfall over already saturated ground has heightened flash-flood risks, prompting repeated advisories to avoid flooded roadways and seek interior shelter.
