Forecasters warned Tuesday that a broad severe-weather outbreak could bring tornadoes, very large hail, damaging winds and flash flooding from the Midwest into the Northeast, with more than 132 million people in the threat area.
Severe storms threatened a large swath of the U.S. on Tuesday, with forecasters warning of tornadoes, very large hail, damaging winds and flash flooding from the Midwest into the Northeast.
The National Weather Service and NOAA weather products said the system could produce severe thunderstorms across parts of the central U.S. and Great Lakes region, while AP reported that forecasters were warning of renewed storm damage across the Plains and Midwest during the afternoon and evening.
FOX Weather said the severe-weather threat covered more than 132 million people from the Midwest to the Northeast on April 14, 2026.
What forecasters said
Official weather guidance flagged several hazards in the same corridor. Those included very large hail, tornadoes, severe wind gusts, heavy rain and possible flash flooding.
The Weather Prediction Center also highlighted rounds of strong to severe thunderstorms and heavy rain across the Upper Midwest and Great Lakes around April 14 and 15.
A local National Weather Service page in Minnesota and Wisconsin marked Tuesday as part of Severe Weather Awareness Week and specifically flagged severe storms, lightning and hail.
What to watch
The highest-risk corridor could shift through the evening as the storm system moves east. The main question for later in the day is whether the Northeast sees organized severe storms or only isolated activity.
Any confirmed tornadoes would still need to be verified by NWS surveys after the event.
This is a developing weather story and should be updated as forecast guidance and warnings change through the day.
