A powerful low-pressure system swept through the Midwest, spawning severe thunderstorms and high winds. Several tornadoes were reported in Iowa, which was among numerous states reporting damage from the fast-moving system.

The Wednesday evening event qualified as a derecho, according to Stu Ostro, Senior Director of Weather Communications at The Weather Channel.

The storms “met the criteria for length and concentration of the swath of wind damage reports,” said Ostro. “This fit more into the ‘serial’ derecho type of classification than a ‘progressive’ derecho.”

One particular blaze threatened several homes as it was whipped by strong winds, according to KWCH.com.

Officials do not believe there were any injuries caused by the inferno.

Missouri

The severe weather in Missouri caused a chlorine gas leak Wednesday evening at a water treatment plant in Parkville, outside Kansas City, KMBC reports. Tanks of chlorine at the site are fitted with special caps that tighten when the power goes off and reopen when the power comes back on. One of the caps failed after the power flickered on and off numerous times due to the heavy weather in the area.

“Northwesterly winds were still gusting over 40 mph near Parkville Wednesday evening, and in a way that would have been good because all that air rushing by would have diluted any cloud of chlorine gas that may have tried to form,” said weather.com senior meteorologist Nick Wiltgen.

According to KMBC, crews contained the leak just before 8 p.m, and no evacuations or injuries were reported.

Kansas City Power & Light reported that nearly 18,000 customers were without power late Wednesday afternoon across its territory in western Missouri and far eastern Kansas. The vast majority of those outages were on the Missouri side of the line, including 6,000 customers in Kansas City proper. The outages were primarily the result of strong winds behind the cold front as skies cleared, and not from thunderstorms.

KCP&L showed 11,000 customers still in the dark as of 7:30 p.m. Wednesday. Most of those outages were restored by Thursday morning.

Ameren reported a smattering of outages across the northern half of the state, amounting to about 2,000 customers at one point Wednesday evening.

Oklahoma

At least one house and one barn in Lenepah went up in flames due to a large wildfire that broke out Wednesday afternoon, Osage Sky News reports. The fire was one of several burning across the state, fanned by high winds that followed severe weather earlier in the day.

The Oklahoma Department of Emergency Management requested the evacuation of Lenepah and Delaware in Nowata County earlier that afternoon. The Oklahoma Forestry Services issued a red flag warning for most of the state lasting until 6 p.m. Wednesday due to high winds across the region.

“Wind gusts of 40 to 50 mph have been reported throughout that region due to the strong low-pressure system moving by to the north,” said Wiltgen. “Nowata County missed out on precipitation from this storm system, so conditions were also dry.”

According to a KFOR.com report, Jones Middle School outside of Oklahoma City, Oklahoma was evacuated after a power pole snapped near the school, likely due to high winds. No injuries were reported immediately following the incident.
