Tulsa, Oklahoma – The chill in the air feels sharper this morning, the kind that hints at the first true touch of winter. Streetlights flicker over damp pavement, and the north wind hums quietly through the trees — a signal that colder air is pressing in fast across Green Country.
The National Weather Service in Tulsa has issued a Freeze Watch for much of eastern Oklahoma and northwest Arkansas, in effect from late tonight through early Sunday. Temperatures are expected to dip as low as 28°F in some rural valleys, with patchy frost developing by daybreak. Sensitive vegetation, garden beds, and exposed pipes could be damaged if left unprotected. Residents should cover tender plants, disconnect hoses, and wrap outdoor faucets before evening.
Saturday’s high will reach the mid-50s before skies clear and winds calm — the perfect recipe for radiational cooling. By Sunday morning, frost will likely blanket rooftops and fields from Tulsa to Tahlequah, while cooler air lingers through the early hours. Sunshine returns quickly, however, helping temperatures rebound into the low 60s by afternoon.
The chill won’t last. A powerful warming trend begins Monday, pushing highs into the upper 60s and low 70s across eastern Oklahoma. By Tuesday, Tulsa may reach the mid-70s under clear blue skies — ideal for early holiday yardwork or fall travel along I-44.
To be fair, this weekend’s Freeze Watch marks the seasonal turning point for the Southern Plains — the moment when late-fall calm meets early winter’s edge. After tonight’s cold bite, the region shifts back toward mild, dry, and sunny November weather through midweek.
