The lows for Wednesday and Thursday nights in Northwest Arkansas are expected to dip into the teens. The extreme cold can be especially difficult for those who live outside, but Leadership Fayetteville is lending a hand. Late Tuesday afternoon, members of the group met in the parking lot of Farmers Co-op Fayetteville and attached tags to scarves that they then tied to a bridge, lampposts and signs along a nearby section of the Frisco Trail.
