Tulsa NWS Office Storm Reports:

Event Summary – April 14, 2011 Tornado and Severe Thunderstorm Event (updated 4/16/11 8:45 pm)

A strong low pressure system moved out of the Rockies and into the Southern Plains on April 14, 2011. A surface low deepened across central Kansas by early afternoon, with a sharp dryline extending from the surface low southward along the I-35 corridor. Moisture continued to increase from northeast Texas into eastern Oklahoma and northwest Arkansas ahead of the dryline, with dewpoints rising into the low to mid 60s. Initial convection occurred along the dryline from near Ponca City to Ardmore at around 3 pm CDT. These storms quickly matured into supercells as they moved further east into eastern Oklahoma due to favorable wind profiles and instability. Storms continued to increase as the dryline slowly moved east during the evening. A 100+ knot westerly upper-level jet was also present across northern Texas, which helped to further enhance the severity of the storms. A trailing cold front overtook the dryline during the late evening hours, leading to additional development and a line of storms across western Arkansas.

Several reports of tornadoes and hail to the size of golf balls and softballs were received by the NWS office in Tulsa through the evening hours as the storms moved through eastern Oklahoma and northwest Arkansas. The storms moved further east into Arkansas and out of the NWS Tulsa area of responsibility by around 1:30 am.

The National Weather Service Office in Tulsa has teams in the field surveying the damage from the April 14th severe thunderstorms. As more information becomes available about the possible tornados, including EF rating and estimated size, this website will be updated. See the map below for preliminary local storm reports. Due to the number of reports, it may take several days for the teams to survey all of the damage.

NWS Tulsa Damage Survey Teams will be evaluating reports of possible tornados and/or damage in the following areas: Additional details will be available once the survey teams have analyzed the data they collected in the field.
