Event Summary - October 13, 2012 (updated at 4 pm 10/18)

Severe thunderstorms developed during the afternoon over central Oklahoma ahead of a cold front moving into the region.  These storms moved into eastern Oklahoma and northwest Arkansas during the late afternoon and evening hours of the 13th.  There were a number of occurrences of damaging wind as these storms moved across the area and one of these storms produced a tornado in Benton County, Arkansas. 

In addition to the severe weather, a band of strong thunderstorms produced locally heavy rainfall across portions of northeast Oklahoma that resulted in flash flooding.  Widespread 2" to 4" fell over portions of Creek, Tulsa, and Rogers Counties.  The Oklahoma Mesonet station in Oilton, OK measured 4.60”, 4.32” was measured 3 miles southeast of Sperry, OK, and 3.66” was measured 1 mile south of Honobia, OK.  Sadly, a young teenager drowned when he and his friends were playing near a swollen creek in Tulsa.  Water in creeks, streams, and drainage areas can rise very rapidly and move very quickly.  Children should be reminded often that playing near these areas is very dangerous.

Detailed Preliminary Survey Information

A National Weather Service Tulsa meteorologist and Benton County Emergency Management officials surveyed storm damage that occurred on the evening of October 13, 2012 across Benton County, Arkansas.  Damage that was investigated was strongly indicative of tornado damage, with trees and signs being blown down in a strongly convergent nature throughout the path.  The tornado developed north-northeast of Cave Springs, east of Rainbow Road and south of Stony Brook Road.  The tornado moved northeast across a subdivision snapping or uprooting a number of trees and damaging homes.  About 450 yards wide, it then moved across a commercial area on the west side of Rogers where it removed part of the roof of a commercial building, blew large glass windows out of another commercial building, damaged a number of other buildings, snapped or uprooted a number of trees, and snapped power poles.  Debris impacted a vehicle, impaling the windshield with a piece of 2x4 wood and shattering several of the windows.  Two people were injured by glass and flying debris in the vehicle.  Damage in this area indicated the wind speed in the tornado was as much as 90 to 100 mph.  The tornado then crossed I-540 and went across another subdivision of homes.  Many trees were snapped or uprooted and homes were damaged.  Tree damage became less concentrated for a bit after the tornado crossed Highway 94, but was intermittently still in the EF-1 category.  Damage northeast of Avoca was once again very concentrated with a number of snapped or uprooted trees as well as home and barn damage.  It dissipated in the southern portion of the Pea Ridge National Military Park.

Information from this event is still considered preliminary and will be modified based on additional information that may become available to us.  Anyone with information that could enhance the record of this event should contact the National Weather Service Office in Tulsa at 918-838-7838 during business hours, or send us an email at sr-tsa.stormreport@noaa.gov, or submit an online report.
