Severe storms in great lakes, Kendra Patrick

Disturbances aloft will continue to rotate around the periphery of a hot high-pressure system centered over Missouri and Kansas. These impulses will help ignite thunderstorms, some severe, from the Rockies to the northern Plains, Great Lakes and Northeast into midweek.

Tuesday's Greatest Severe Storm Threat

Tuesday's Greatest Severe Storm Threat

(LIVE: Radar, Watches and Warnings)
Tuesday, the most organized threat of severe weather (large hail, damaging winds, and perhaps a tornado) will be in the Great Lakes, including states like Wisconsin, Michigan, Ohio and Indiana. See the red area on our inset map for details.
More hit-or-miss thunderstorms will rumble again over parts of the Rockies and Desert Southwest, with the threat of local flash flooding, hail, and brief wind gusts possible. Lightning strikes may initiate new wildfires, and shifting winds and/or heavy rain may cause headaches near existing wildfires.
For parts of the Gulf Coast states, scattered thunderstorms may interrupt your beach or golf plans, especially along the Texas coast and southwest Florida. Be sure to head indoors as soon as you hear thunder. The best chance for heavy rainfall is expected to focus on the Louisiana and Texas portions of the Gulf Coast.
