This weekend's extreme weather conditions, that included damaging thunderstorms and tornadoes in several Southern states, will continue through the first half of this week, reports the Washington Post.

Why it matters: More than 100 million Americans are facing an "elevated threat of thunderstorms" on Monday, some of which could prove severe, per the Post.

Details: A tornado touched down in the Atlanta area Monday morning and a tornado watch is in effect for parts of Georgia and Alabama. Storms could reach the Ohio river valley on Tuesday, reports CNN.

  • A tornado warning was issued Monday for Charlotte, North Carolina, reports the Post.
  • Roughly six tornadoes moved through Mississippi Sunday evening, causing "extensive residential damage" in some parts as the storm system moved through the state. Tornadoes also touched down in Nebraska and Colorado, per the Post.
  • Storm damage was also reported in Kentucky and a tornado warning issued for parts of Tennessee, reports the New York Times.

Our thought bubble, from Axios' climate reporter Andrew Freedman: The highest probability of severe weather stretches from northeastern Texas to western Kentucky and Tennessee through Monday night.

  • However, the ongoing storm system has already proved to be especially menacing, with a "tornado emergency" declared for Tupelo, Miss. on Sunday night, and tornado warnings issued for downtown Atlanta as well as the city of Charlotte so far on Monday.
  • Over the weekend, grapefruit-sized hail fell in Texas and Oklahoma, with more large hail forecast today.

The CDC announced in new guidance Thursday that anyone who is fully vaccinated can participate in indoor and outdoor activities without wearing a mask or physically distancing, regardless of crowd size.

What they're saying: "If you are fully vaccinated, you are protected, and you can start doing the things that you stopped doing because of the pandemic," CDC Director Rochelle Walensky will say at a White House press briefing.

Colonial Pipeline paid hackers linked to the DarkSide cybercrime group nearly $5 million in cryptocurrency after last week's ransomware attack, Bloomberg first reported and the New York Times confirmed.

Why it matters: The breach of the largest refined fuels pipeline in the U.S. triggered new concerns about the vulnerability of the country's increasingly digitized energy systems.

President Biden on Thursday warned gas companies to not price gouge amid major shortages following the Colonial Pipeline cyberattack.

The big picture: Biden added that the FBI does not believe the Russian government is behind the attack, but they do know that those responsible "are living in Russia."
