What happened
The episode as NWS TSA wrote it up.
An upper level disturbance moved into the Southern Plains from the Southern Rockies on the 8th. A large area of precipitation developed as the system approached. Rain changed to snow in extreme northeastern Oklahoma during the evening of the 7th and gradually transitioned southward during the morning hours of the 8th. Temperatures remained near 32 degrees so much of the snow melted on contact due to the relatively warm ground but 1 to 3 inches accumulated during the event north of a Clayton to Poteau line. Four to six inches fell in some of the higher terrain in extreme eastern Oklahoma where temperatures had fallen into the upper 20s during the event.
What forecasters said that day
