Wintry precipitation chances in the form of snow and or a mix of sleet develop starting noon Saturday for Northeast Oklahoma and then spread across Eastern Oklahoma and Northwest Arkansas through Saturday evening. Precipitation chances should taper off during the evening hours and exit the region around midnight Saturday night. Forecast snowfall accumulations continue to be around 1 inch possible north of Interstate 44 with around a half inch for the rest of Northeast Oklahoma into far Northwest Arkansas. Minor to no accumulations are anticipated for Southeast Oklahoma into parts of West Central Arkansas. A winter weather advisory is in effect from noon Saturday to midnight Saturday night for counties along the Kansas border and also Pawnee county in Northeast Oklahoma.
Behind the exiting precipitation Saturday night, the coldest temperatures of the season thus far and breezy north winds will create wind chill values in the range of 5 above zero near the Red River to around 15 below zero near the Kansas border. A wind chill advisory will likely be needed for late Saturday night into Sunday morning. Cold conditions continue Sunday with highs in the 20s for most locations. Lighter winds Sunday night into Monday morning will allow for wind chill values in the range of mid teens to around 5 below zero.
Confidence continues to increase in likely wintry precipitation...with the greater potential along and north of Interstate 44.. Snowfall amounts/locations and wind chill values this weekend will continue to be refined over the next 24 hours.
