Severe weather left a trail of destruction across the Heartland on Friday, with 83 tornado outbreaks reported across five states.
A multi-day tornado outbreak continues Saturday, with powerful storms expected from Texas to the Great Lakes.
Tornado watches were in effect late into the night for parts of six states, from Texas to Iowa. This clock may expand slightly to the east as the day progresses.
Saturday's outlook calls for a moderate risk (Level 4 out of 5) for parts of Texas, Oklahoma, Kansas and Missouri, with the storm expected to intensify again in the afternoon and evening across large parts of the country. It is expected. In addition to strong, long-track tornadoes, very large hail up to 3 inches in diameter and thunderstorms with wind speeds of up to 80 mph are possible.
In addition to dozens of tornado reports Friday, there were 33 reports of damaging winds and 60 reports of large hail.
In Iowa, four people were injured and about 120 structures were damaged as severe weather hit Pottawattamie County on Friday, county officials said.
The city of Minden was hardest hit by Friday's storm, according to the county. Gas and electricity were cut off and a 10pm curfew was imposed until further notice.
Gov. Kim Reynolds, Pottawattamie County and the city of Minden have all declared states of emergency.
Severe damage was also reported in eastern Nebraska on Friday, including in Douglas County, where hundreds of homes were damaged in the Omaha area.
Preliminary information suggests two “strong and unusual tornadoes” touched down in Douglas County, Chris Franks of the National Weather Service said at a news conference Saturday. Franks said the National Weather Service found evidence of EF-2 and EF-3 tornado damage there after Friday's storm.
No deaths have been reported so far from the storm, officials said.
“It's hard to imagine a storm of this magnitude causing such extensive property damage with no loss of life,” Douglas County Emergency Management Director Paul Johnson said at a news conference. “This is a great attribute for the city of Omaha.”
Nebraska Gov. Jim Pillen urged the public to continue to stay safe as the storm threat continues into Saturday night.
There have been seven tornado reports so far Saturday. One tornado emergency was issued in Knox, Texas, after a large and damaging tornado was reported near the town. The tornado storm reportedly produced hail the size of baseballs.
On Saturday, a tornado was confirmed near the intersection of Kansas, Nebraska, and Missouri. The confirmed tornado occurred 8 miles north of Robinson, Kansas.
All modes of severe weather are expected on Saturday.
Damaging winds, large hail, and long-track tornadoes are possible, especially in Kansas, Oklahoma, and northeast Texas. Overall, there is a threat of severe weather extending across the central United States from Canada to Mexico.
The threat of these dangerous storms continues into the night.
In addition to the threat of thunderstorms, this major storm system also carries the risk of flash flooding.
Flood watches are in place for eight states from Texas to Iowa until Monday afternoon. This is because heavy rain can cause large amounts of rain to fall in a short period of time, potentially causing dangerous flash flooding.
More than 2 to 5 inches of rain could fall in a short period of time, and the Weather Prediction Center has issued a “moderate risk” for excessive rainfall from Texas to Missouri.
“Significant flash flooding remains likely across parts of east-central Oklahoma, with Saturday precipitation totals increasing late this evening into Saturday night,” the Weather Prediction Center said.
A “high risk” of excessive rainfall is the highest possible level of threat. One-third of flood-related deaths occur in high-risk areas. This is a prediction of a rare and life-threatening severe flood event, leading to a high-risk issuance.
The National Weather Service plans to conduct a damage survey this weekend to determine details such as the number of confirmed tornadoes and strength ratings.
The threat will reduce by Sunday, but wind damage, large hail, and a few tornadoes are possible from Austin, Texas, to Davenport, Iowa, including Shreveport, Louisiana. Little Rock, Arkansas. Kansas City and St. Louis, Missouri.
