The new model runs have taken the surface low further north, keeping the heaviest of the snow forecast across NE OK, SW MO, and SE KS. The 250 mb jetstreak doesn't dive as far south as originally forecasted. This change aloft has moved the position of the surface low further north.

There is still plenty of uncertainty with this system, so we'll be watching each run and updating the map. Right now most of northwest Arkansas has the potential to pick up 1 inch of snow, with the upper elevations having the potential for higher totals from 2 to 3 inches.

Delaware county and McDonald county could see 3 to 4 inches of snow by Saturday afternoon. The River Valley, as always, still remains the location of the most uncertainty. The cold air may not work far enough south for a total changeover. Grassy surfaces may see a dusting to an inch by Saturday afternoon.
