The worst severe weather outbreak so far this year will continue to unfold through Sunday night with the danger of violent tornadoes high in the vicinity of Arkansas and southern Missouri.
Places from northeastern Texas and northern Louisiana to southern Iowa and Illinois will remain at risk for one or two rounds of violent thunderstorms to close out the weekend.
The danger zone also extends back to Nebraska.
The strongest thunderstorms will remain capable of producing damaging winds, large hail, frequent lightning and destructive tornadoes.
Cities within this zone include St. Louis, Jefferson City, Joplin and Springfield, Mo.; Jonesboro and Little Rock, Ark.; Shreveport, La.; and Tyler, Texas.
The greatest risk of violent tornadoes is centered around Arkansas and southern Missouri.
Some tornadoes that develop in this area could be long-lived, tracking on the ground for many miles before the storm weakens and the twister lifts off the ground.
An added danger will accompany the storms as they continue into Sunday night with the cover of darkness making it difficult to see a storm as it approaches.
It is important to know the difference between a tornado watch and a tornado warning.
A tornado watch means that conditions are conducive to the development of thunderstorms capable of producing a tornado. Meanwhile, a warning means that a tornado is imminent or may already be on the ground.
If you find yourself in a tornado warning, you should take shelter until the storm has passed and the tornado warning has been lifted.
If you have plans to spend any time in the outdoors, you should pay close attention to the forecast and fast-changing weather conditions so you don't get stuck in the middle of a severe thunderstorm.
Now would be a good time to review tornado safety measures and make a plan in case you are impacted by one of these severe storms.
The threat for severe weather will slowly shift eastward heading into the start of this week, stretching from Alabama to Ohio on both Monday and Tuesday.
Another round of rain is expected to move through the Carolinas on Saturday, which may lead to rises on some small streams and creeks.
A strengthening storm system will bring the threat for flooding, mudslides and severe thunderstorms to areas from Italy into the Balkans later Friday into the weekend.
Winter will kick off with mild weather in the Northeast and mid-Atlantic as an intensifying El Nino influences the weather pattern across the country.
A "blob" of abnormally cold water in the North Atlantic, located near Greenland, has the potential to put enough drag on the ocean current to impact weather conditions in the years to come.
“It was by far the most intimidating natural disaster I have ever chased,” Storm Chaser and Extreme Meteorologist Reed Timmer said of the historic flooding in South Carolina.
Cool weekend weather is in store for the Northeast after rain and thunderstorms dampen the region on Friday.
