...WINTER STORM WARNING IS CANCELLED...

The potential for additional accumulating snow has ended across
much of eastern Oklahoma and portions of far northwest Arkansas.
Isolated flurries may continue through the afternoon however no
little to no accumulation is expected. Roadways likely remain snow
packed across much of the region and travel conditions will
continue to be impacted.  

Additionally, the extended duration of very cold temperatures has
resulted in unusual demand on the electrical system across the 
region and rolling blackouts remain possible. You are encouraged 
to find ways to conserve power over the next few days until the 
arctic cold leaves.
