Organizers in Wisconsin postponed the biggest air show in the U.S. as a severe storm system threatened the Midwest with potentially hurricane-force winds, tornados, hail and thunderstorms overnight.

Threat level: More than 5.9 million people could be affected by the storm system — which saw the EAA AirVenture in Oshkosh, Wisconsin, postpone events due to be held Wednesday until the following evening amid the threat of 90 mph winds.

A tweet previously embedded here has been deleted or was tweeted from an account that has been suspended or deleted.
  • Storms moving through southern Wisconsin were bringing "damaging winds along the line" and the threat of tornadoes in the southeast of the state on Thursday morning, according to the NWS.
  • "Thunderstorms associated with wind damage and a risk for a tornado, will be possible from the Ohio Valley, central Appalachians and Mid-Atlantic states on Thursday," the National Weather Service's Storm Prediction Center said early Thursday.
  • The National Weather Service issued a level 3 out of 5 storm outlook, an an "enhanced" risk of severe weather, across the Mid-Atlantic states on Thursday, including Washington, Baltimore and Philadelphia.

The big picture: The latest in a series of heat waves that was bringing extremely hot temperatures to the Central U.S. Wednesday contributed to the severe storm system in the Midwest, per Axios' Andrew Freedman.

  • Such weather patterns often lead to so-called derecho events, characterized by an organized group of severe thunderstorms that brings damaging straight-line winds across long distances, Freedman notes.

Flashback: A derecho that struck parts of Iowa and Indiana last year caused some $7.5 billion in damages.

Rare "high-risk" flash flood alert issued as Nicholas nears Louisiana

Southwest Louisiana faces a "high risk" of flash flooding from Tropical Depression Nicholas on Wednesday morning, the National Weather Service warned.

Why it matters: Such "high risk" outlooks are rarely issued anywhere in the U.S. There's also a medium risk of flash-flooding in New Orleans, which is still reeling from Hurricane Ida striking the state last month.

The Exvangelicals

Even as evangelicals maintain their position as the most popular religion in the U.S., a movement of self-described "exvangelicals" is breaking away, using social media to engage tens of thousands of former faithful.

The big picture: Donald Trump's presidency, as well as movements around LGBTQ rights, #MeToo and Black Lives Matter, drew more Americans into evangelical churches while also pushing some existing members away.

Huge wildfire reaches edge of Sequoia National Park

Firefighters in Sequoia National Park were working into the night after two wildfires merged to reach the Giant Forest Saturday.

Why it matters: This forest contains over 2,000 giant sequoias, including the General Sherman Tree — the world's largest tree by volume. Park officials wrapped the redwoods in foil last week as the Paradise and Colony Fires, now known as the KNP Complex Fire, neared. Protection efforts appeared to be working overnight.
