Fort Smith, Arkansas — One hundred sixty million Americans are prepared and monitoring what forecasters say is shaping up to be the largest snowstorm of the season, as winter storm warnings remain in effect across portions of Oklahoma and Arkansas through Monday, Jan. 26.
For this region, the first phase of the storm is expected to produce widespread snow, especially across eastern Oklahoma and northern and western Arkansas. According to the National Weather Service, snowfall totals of 6 to 12 inches are likely across much of northeastern Oklahoma and the Arkansas River Valley, with locally higher amounts possible near the Ozarks and areas north of the Interstate 40 corridor.
The National Weather Service Weather Prediction Center places the Oklahoma–Arkansas region within a moderate to high-confidence zone for impactful winter weather from Friday through Sunday. Snowfall rates may approach one inch per hour at times, sharply reducing visibility and creating hazardous travel conditions along major corridors, including Interstate 40, Interstate 44, Interstate 49, and U.S. Route 64.
Transportation officials warn that prolonged snowfall combined with falling temperatures could lead to icy road conditions, extended travel delays, and stranded vehicles, particularly during overnight and early morning hours. Snow-covered highways and blowing snow may make travel unsafe or temporarily impossible during peak snowfall periods.
Residents are urged to complete storm preparations before conditions deteriorate, including stocking food, medications, and emergency supplies. Motorists are advised to avoid non-essential travel during periods of heavy snowfall and to closely monitor roadway conditions if travel cannot be postponed. Commuters, freight operators, and energy workers should expect disruptions that may extend into early next week.
Behind the storm, a surge of Arctic air is forecast to settle across Oklahoma, Arkansas, and much of the southern Plains. Temperatures are expected to plunge well below seasonal averages, locking snowpack in place and prolonging hazardous conditions even after snowfall ends.
While a brief lull in snowfall is possible between Jan. 28 and Feb. 1, forecasters caution that the Midwest and East Coast will remain entrenched in a deep Arctic pattern into early February, limiting melting and extending winter impacts across the region.
