STEVE LEWIS/Durango Herald<br><br>Owen Littleton, 9, left, and Linkin Griego, 7, and their classmates in the Durango School District 9-R Shared School program got a chance to play at the Mason Center and enjoy the warm weather Tuesday afternoon. Owen is the son of Kara and Matt Littleton, and Linkin is the son of Lacie and D.J. Griego. Durango’s sun-splashed winter may take a break Thursday, with the National Weather Service expecting a 30 percent chance of snow, and there’s a slight chance snowflakes could be in the air as soon tonight.
