Weekly Wrap-Up: Powerful Storms Bring Flooding, Tornadoes and Snow to Central US

An outbreak of violent thunderstorms lashed portions of the central and southern Plains states early this week, spawning tornadoes and causing flash flooding in the region.

Widespread disruptions and power outages were reported across the Central states into Sunday night.

More than 100 award-ceremony attendees at a high school in Lake City, Iowa, were also caught in the midst of the severe weather outbreak Sunday evening as a possible tornado tore the roof apart right over their heads.

Fortunately, the 150 people inside South Central Calhoun High School were moved to the basement and locker room area two minutes before the potential tornado struck.

In Texas, a significant amount of rainfall led to flash flood emergencies in some areas with the heaviest rain falling southeast of Dallas.

The town of Corsicana received more than twice the amount of rain that they typically receive in all of May within a six-hour period. The area received 9 inches of rain in a span of six hours.

Five fatalities were reported on Sunday as storms swept from Texas to South Dakota. One person died due to flooding in Corsicana, Texas.

Interstate 45, a highway that connects Dallas to Houston, was closed for several hours as the torrential rain inundated the road. Secondary roadways in the area remained closed into Monday morning. Numerous water rescues were performed across Texas throughout the weekend.

Two were killed in Nashville, Arkansas, after a possible tornado swept through a trailer park Sunday night.

Thousands were without power Sunday into Monday morning in Texas and Arkansas as winds up to 60 mph continued to lash the region.

The potent storm system continued to move eastward across the Central states into Monday night.

After violent thunderstorms rattled the Plains both days of the weekend, the threat shifted from the Lower Peninsula of Michigan to southern and coastal Texas.

Heavy rain continued to soak the area through midweek, leaving some areas of Texas and Oklahoma under floodwaters.

In addition to severe storms across the southern and central Plains states, heavy snow fell from Denver to Cheyenne and Casper, Wyoming, and eastward to South Dakota on Sunday. The snow fell on the back edge of the same storm system walloping the Plains with severe storms and flooding.

The highest totals in Colorado include 26 inches at Wolf Creek, at an elevation 11,000 feet and Echo Lake with 23 inches at 10,600 feet. Hayden Pass also received 21 inches at an elevation of 10,720 feet.

Denver International picked up 4 inches, AccuWeather Meteorologist Rebecca Elliot said.

"Colorado was the hardest hit with nearly 2 feet of snow at the higher elevations and up to 8 inches of rain falling along the Front Range," she said. "While the mountains were getting snow, the eastern half of the state was receiving a lot of rain."

In Nepal, another deadly earthquake rattled the region just weeks after the area suffered a devastating quake that killed more than 8,200 people, according to The Associated Press.

The second powerful earthquake, 7.3 in magnitude, struck Nepal on Tuesday. According to the USGS, Tuesday's earthquake is the largest aftershock to date of the magnitude-7.8 on April 25, 2015, Nepal earthquake - known as the Gorkha earthquake.

The earthquake was able to be felt in the nearby countries of India, Bhutan and Bangladesh, according to reports from the USGS.

The epicenter was located 76 km (47 miles) east of Kathmandu, the capital of Nepal, according to the U.S. Geological Survey.

This earthquake is considered to be a shallow earthquake, having a depth of only 15 km (9.3 miles). Shallow earthquakes of this nature typically cause more damage than those of a similar magnitude at a greater depth.

The Nepal Times reported that houses collapsed in Kathmandu, Bhaktaput, Lalitpur, Dolakha and Sindhupalchok districts following the tremor which has killed dozens of people and left thousands more injured.
