The Norman, Oklahoma National Weather Service Office (OUN-NWS) monitors how often they issue TORNADO WARNINGS and how often confirmed tornadoes touch down in their County Warning Area (CWA).
Recently, the Norman Office announced on twitter that it had been a record amount of time since a confirmed tornado had touched down in its CWA and also a record amount of time since the office had issued a TORNADO WARNING.
Both streaks of time without activity came to an end on Sunday and in the style of the recent past the announcement of the end of that time period came on Twitter.
On Sunday a brief tornado was caught on camera from a KWTV chopper that was flying over Stephens County. The tornado touched down east of Duncan and north-northeast of Velma. At the time of writing this we do not know of any damage. And, there has been no reports of injuries from the twister. Since there was no reports of damage the National Weather Service will not be sending an investigation team to check out the tornado aftermath. This is a good sign that the impact of the tornado on the surrounding area of Stephens County was minimal at best.
This was the first confirmed tornado to touch down in Texoma as well as the state of Oklahoma in the calendar year 2014.
The last tornado to touch down in Oklahoma was on August 7, 2013 in Beaver County. Beaver County is located in the Oklahoma Panhandle, also known as "No Man's Land." That makes the length of no tornado activity in Oklahoma to be 250 days.
