Oklahoma–Arkansas – Rain chances are expected to increase across Oklahoma and Arkansas during the January 7–13 period, according to the latest federal weather outlook, signaling a wetter pattern developing across the southern Plains and Lower Mississippi Valley.
According to the National Weather Service Climate Prediction Center, both states are included in a region forecast for near- to above-normal precipitation during the 8–14 day window. In January, this pattern supports multiple rounds of rainfall as storm systems move eastward from the Plains into the mid-South.
Much of Oklahoma and Arkansas falls within the 33–50% probability range for above-normal precipitation, indicating an increased likelihood of several rain events rather than one prolonged system. Eastern Oklahoma and much of Arkansas may see more frequent rainfall, while western Oklahoma could experience more intermittent rain depending on storm track and timing.
Temperature outlooks for the same timeframe indicate near-normal temperatures across the region. This setup favors rain as the dominant precipitation type and limits the potential for winter weather impacts, though brief cool-downs may follow frontal passages.
For commuters, students, and freight operators, increased rain chances may lead to slick roads, reduced visibility, and slower travel during heavier rainfall. Major corridors including Interstate 35, Interstate 40, Interstate 44, Interstate 49, U.S. 60, and U.S. 67 may be impacted, particularly in urban areas such as Oklahoma City, Tulsa, Fort Smith, Fayetteville, Little Rock, and surrounding communities.
Repeated rainfall could result in localized ponding on roads and brief rises on small creeks and streams, especially in low-lying or poorly drained areas. Agricultural fields and rural roads may also experience short-term drainage issues if rain events occur close together.
Forecasters emphasize that 8–14 day outlooks reflect probability trends, not specific rainfall totals or storm timing. Residents are encouraged to monitor daily forecasts and updates from local National Weather Service offices as the period approaches.
No flood watches or rain-related advisories are currently in effect based solely on this outlook, but the signal supports increased awareness for wet-weather impacts during the second week of January.
