So long 70, hello snow. 

Tulsa's weather has transitioned from warm and windy to cold and wet. 

A winter weather advisory is  in effect for portions of Green Country. 

Osage, Washington, Nowata, Craig, Ottawa, Delaware, and Adair are among the counties under the winter weather advisory. 

News on 6 Meteorologist Travis Meyer says, "We have a chance of snow and sleet, and that means some slick roads, bridges and overpasses from Tulsa to the north and east.  We're looking at not a whole lot of accumulation in Tulsa, but we could have a couple of inches near Tulsa, with a little more snow possible north and east of Tulsa." 

Meyer says Sunday will be cold and blustery, with highs in the mid 30's. 

Sunday night's low will plummet to 15.
