(TULSA, Okla.) A line of thunderstorms is expected to sweep across northeast Oklahoma after midnight Tuesday. Damaging winds will be the primary threat, with an isolated short-lived tornado and large hail possible as well. Thunderstorms are expected to develop in the vicinity of the dry line across the Texas Panhandle and near a stationary boundary across southwest Kansas late Tuesday afternoon as a mid-level shortwave moves across the Southwest United States. This activity will then spread into eastern Oklahoma late Tuesday evening and then spread across the entire Tulsa County Warning Area as we move through the overnight hours and eventually into Wednesday morning. Some of these storms could be severe especially across eastern Oklahoma where conditions will be most favorable. Large hail and damaging winds will be the main concern. The aforementioned thunderstorm complex may steal some of the thunder from the activity that is expected on Wednesday evening into Wednesday night as the airmass across the area may not have enough time to recover before a cold front moves through Wednesday night. While thunderstorms are expected in the vicinity of the front as it moves through the region, coverage will not be as great as it would have been without the morning storms. It is still possible that some of these storms could be severe. The showers and thunderstorms will come to an end Thursday morning as the cold front exits the area. After the cold front moves through the area Wednesday night into Thursday morning, temperatures are set to be below seasonal normals into early next week. The next chance of showers and thunderstorms will come Friday night into Saturday night as a southwesterly flow aloft develops across the area before a northern stream trof sweeps through the area Saturday night.
