November 13, 2015 - UNITED STATES - 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."
Here are the latest impacts from each state affected by this round of severe weather.

Kansas
The Kansas City Board of Public Utilities reported that more than 1,600
customers were without power Wednesday. Westar Energy reported 3,550
customers without power in central and eastern Kansas, while the utility
company Empire reported nearly 1,500 customers without power.
By Thursday morning, only a few hundred of those outages remained.
The National Weather Service office in Springfield, Missouri, reported
several grass fires across southeastern Kansas due to strong winds.
There were also numerous reports from law enforcement of power lines
down due to strong winds across Crawford, Bourbon, and Cherokee
Counties, the NWS reports.
One particular blaze threatened several homes as it was whipped by
strong winds, according to KWCH.com. It took more than a dozen
firefighting crews to push the flames away from the residences, which
was believed to have been started by arcing power lines, the Atlanta
Fire Chief in Cowley County told 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.
The NWS in Kansas City reported a tree down on a house and multiple
carports destroyed in Putnam County, with multiple reports of damage on
the east side of Unionville. The NWS has also reported a large portion
of shingled roof blown off in Grundy County around 2:45 p.m. local time.

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. -
