Winter Weather Advisory remains in effect, chance for tornadoes Wednesday night

(TULSA, Okla.) Light ice accumulation may occur across parts of northeast Oklahoma generally northwest of I-44 through noon Wednesday, which may cause a few slick spots on bridges, overpasses, and untreated roadways. A Winter Weather Advisory remains in effect for Osage, Washington, Nowata, Craig and Pawnee Counties, including the cities of Pawhuska, Bartlesville, Nowata, Vinita, and Pawnee, until noon Wednesday. Light icing could create slick spots on bridges and overpasses. Be prepared for slippery roads. Slow down and use caution while driving. The current round of rain and scattered thunderstorms will exit the area later Wednesday, with another area of rain to the southwest in Texas that will at least impact southeast Oklahoma. Expect the boundary to move very little moving forward on Wednesday, so once again contrasting temperatures will be realized as southeast Oklahoma and parts of northwest Arkansas will remain in the warm sector today. Severe thunderstorm chances will increase this afternoon and continue into the evening and overnight hours. There will be a threat of isolated tornadoes near the surface boundary across southeast Oklahoma into northwest Arkansas. Storms in the colder air will have a hail potential, while storms that get going in the warm sector will have tornadic potential. The severe threat should diminish between 3 and 6 a.m. Thursday with chances for lingering moderate to heavy freezing rain late Wednesday into Thursday, mainly north of Interstate 40. Cold air will continue to filter into the area which will result in a chilly end to the work week. Temperatures are expected to moderate over the weekend with precipitation chances again to increase later in the weekend and into next week as the southwesterly upper flow gets active again. Depending on the timing for developing precipitation over the weekend, there will be potential for a small window for light freezing rain across late Saturday night into Sunday morning.
