Wintry mix looking possible for Tuesday

(TULSA, Okla.) A complicated forecast is shaping up for Tuesday and Tuesday night as a cold air mass will be in place over the region ahead of a low pressure system. This will allow for the potential for multiple precipitation types over much of eastern Oklahoma and also northwest Arkansas. A cold front moved through southeast Oklahoma into far northwest Arkansas Sunday morning. Cold conditions will continue tonight into Monday morning as surface high pressure builds into the region. At this time, a rain and wintry mix looks possible north of Interstate 40, with a rain and freezing rain mix possible along and south of Interstate 40. Closer to the Red River, precipitation looks to remain as rain. Uncertainties remain with locations of these precipitation types and also the amounts of snow and ice accumulations. Temperatures will likely hold or fall to around freezing as precipitation develops through the day. Best chance for rain and/or freezing rain to transition to snow will likely be in areas north and west of Tulsa. Any winter weather threat will end Tuesday night as upper jet streak lifts northeast. Models predict more precipitation during the day Thursday, with heavier rain possible well east of the area during this time and a significant warmup into Friday. Better rain chances are expected by Saturday as the main upper low approaches.
