LITTLE ROCK, Ark. (AP) — Much of Arkansas will be under a winter storm warning or advisory as a blast of Arctic air is expected to dump several inches of snow in parts of the state and send temperatures plummeting.

The National Weather Service issued the warning for Monday evening through Tuesday. About half the state could see snowfall totals between 2 and 3 inches.

Ahead of the storm, two school districts in northwest Arkansas closed early Monday and state transportation officials reported slush or snow on roads near Siloam Springs, Harrison and Eureka Springs.

Counties in northeast Oklahoma and northwest Arkansas will be under a winter weather advisory, with up to 2 inches of snow possible by Monday night.

Temperatures in parts of Arkansas and Oklahoma are expected to fall into the 20s.
