The above image from the Ft. Smith radar a moment ago shows widespread heavy snow exiting Northeast Oklahoma, but still traversing across Arkansas.
Very impressive snowfall totals of 20-25 inches have been coming in from the Rogers / Bentonville areas in northwest Arkansas. Strong, gusty North winds are causing widespread blowing and drifting.
Back West in Oklahoma, Spavinaw reports 23 inches on the ground. Claremore has 19 inches. Tulsa has averaged 6-10 inches, depending on what part of town you're in.
I'll make a more detailed post regarding snowfall totals later this afternoon.
