Winter storm warnings remain on Thursday and should expire pre-dawn Friday as the last wave of energy exits the state to the northeast. Some moderate to heavy snow bands will exit far eastern OK early Thursday morning but the final upper trough to the west will bring at least another chance for some snow across the region this afternoon and evening. The remainder of precipitation will be mostly light, but there will be a chance to add another 1 to 3 inches of snow on top of the snowpack later Thursday. The vector of the wind may also produce some lake effect snow near and south-southwest of some area lakes. This could bring some scattered snow showers into the Tulsa metro at times throughout the day. But the higher chances will be later Thursday afternoon and evening as the last piece of energy with this system moves across the area.
