Intense flooding and violent tornadoes left a path of destruction across the southern Plains, claiming multiple lives in Missouri, Oklahoma and Iowa.
The focus of the tornado outbreak was on Jefferson City, Missouri, which took a direct hit from a massive tornado on Wednesday night. On Thursday, Missouri Governor Mike Parsons confirmed power outages and damage dealt to state buildings. Earlier in the week, he had previously declared a state of emergency in response to the flood threats and severe weather.
One of the fatalities was a result of drowning when a driver attempted to cross a flooded roadway in Perkins, Oklahoma, emergency management officials said. Two more bodies were found in a submerged vehicle near the Mississippi River in Missouri.
According to the National Weather Service's Storm Prediction Center (SPC), there were more than 120 tornado reports from Monday to Thursday. This does not mean that exactly 120 tornadoes occurred, as some of the reports can come from multiple people for the same tornado.
In Golden City, Missouri, three residents were killed Wednesday after a tornadic thunderstorm tracked from Ottawa County to Golden City. The roof of a fertilizer plant was also ripped off during the storm, causing an evacuation within a 1-mile radius due to the threat of a chemical leak.
In total, nine people were killed as a result of the severe weather and flooding this past week in the Central states.
The SPC issued a high risk for severe weather across portions of Oklahoma and Texas on Monday, the first time a high risk area has been issued by the agency since May 2017. The severe outbreak brought the highest tornado risk since April 14, 2012.

On Thursday, Jefferson City Mayor Carrie Tergin imposed a curfew from 9 p.m. to 5 a.m. as crews continue to assess the damage. According to poweroutage.us, the deadly storms left over 21,000 Missouri residents without electricity on Wednesday night.
As a result of the heavy rain, at least four levees were overwhelmed across Missouri. According to the Twitter account @MissouriLevees, 51 of the state’s 64 levees are forecast to overtop by the end of the week.
“Emergency personnel are continuing to contact displaced residents in the affected area,” officials said in a statement. “Citizens are urged to stay away from the impacted area to allow emergency personnel to access.”
Flooding was a big concern for some communities in Oklahoma in the wake of the tornadoes as several communities were forced to evacuate. The Arkansas River near Tulsa reached its highest level since 1986 on Wednesday when it reached moderate flood stage.
The town of Webbers Falls, Oklahoma, was one of the communities that ordered evacuations earlier this week due to the floodwaters. Town officials said it remained closed on Thursday due to rising waters.
The "life-threatening situation was compounded by the fact that two barges, carrying about 1,500 tons of non-toxic fertilizer, broke loose and began floating uncontrollably down the swollen river and towards the Webbers Falls Lock and Dam.
On Thursday, the two barges hit the dam and sunk immediately, leaving some damage but not causing a catastrophic dam failure as some had feared.
The U.S. Army Corps of Engineers said damage from the barges was "minimal."
"Tulsa District engineers were immediately deployed to the structure to inspect the integrity of the dam. Initial observations are that the structural damage is minimal," officials with the corps said. "We found no integrity issues that make us concerned that it will not perform as designed.
The officials added that the submerged barge debris was obstructing three flood gates on the dam from being able to fully close.
This still image from video provided by KFOR-TV shows two unmanned barges that broke loose on the swollen Arkansas River in Oklahoma, head down stream hours earlier and crashing into a dam and sinking Thursday, not causing the structure to fail, which officials feared might happen.
Thousands of miles away in the Atlantic, threats of severe weather were avoided when Subtropical Storm Andrea weakened to an extratropical storm. Andrea became the first named storm of the 2019 Atlantic season on Monday.
While Andrea weakened within 24 hours of naming, AccuWeather forecasters continue to predict for 12 to 14 tropical cyclones to occur this season. Of those 14, two to four are forecast to become major hurricanes.

The same storms responsible for the rounds of severe storms also produced some wintry conditions across the country.
Thirteen states, mainly in the western U.S., received measurable snowfall early this week. While some social media users expressed excitement with this May snowfall, many more expressed disappointment with snow only several days before Memorial Day weekend.
The heavy, late-season snowfall caused travel disturbances and a major pileup in the Denver area. Several surrounding regions in Colorado accumulated more than a foot of snow by Tuesday morning. Black Forest was clobbered by 20 inches, and Peyton was buried by 18 inches.
Colorado was not the only state to experience considerable snowfall early this week. Several locations in South Dakota were inundated with over a foot of snow, and in one case over 2 feet of snow, into Wednesday. For example, a whopping 25 inches buried Pactola Reservoir by Wednesday morning.
In Canada, thousands of Alberta residents have been forced to leave their homes as a result of 30 active wildfires raging through the province. High Level, the town most directly impacted by the blazes, performed a controlled burn on Wednesday afternoon to slow the spread of the fires.

High Level Fire Chief Rodney Schmidt added that favorable conditions, such as light winds, have assisted firefighters and helped crews protect electrical poles in the town. The Chuckegg Creek Fire has covered nearly 400 miles of land near the town and is one of six fires that are out of control.
Thanks to the favorable winds and assistance from firefighters across the country, no homes have been damaged by the Chuckegg Creek Fire. Although the blaze has knocked out power in the area, the region was able to organize a widespread evacuation, as over 5,000 Albertans traveled south away from the blazes.
