Strong to severe thunderstorms are ongoing early this morning across northeast Oklahoma, with damaging winds and large hail being the main threat. Additional strong to severe storms will likely move into parts of southeast Oklahoma early this morning, with the activity eventually shifting into northwest Arkansas. While damaging winds and large hail will be the primary severe weather threat, forecast wind shear will be supportive of a tornado or two. The upper level system will track across northeast Oklahoma during the afternoon, with scattered showers and a few thunderstorms possible. A brief tornado or landspout could occur beneath the upper system. Gusty northwest winds will develop later this afternoon and persist into the overnight hours. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Activation of the Regional Spotter Network Likely. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday.

MONDAY...Thunderstorm Potential...High Wind Potential...Heavy Rain Potential. TUESDAY...Thunderstorm Potential. EXTENDED DISCUSSION... Breezy northwest winds are forecast for Thursday behind the low pressure system. The strong winds and drier air will elevate fire weather concerns although much cooler weather and some light rain across parts of northeast Oklahoma and northwest Arkansas will temper the threat however. Strong south winds will raise fire weather concerns Sunday. A cold front will bring the next chance for rain and storms by Monday into Tuesday. Some locally heavy rainfall will be possible with this system. weather.gov/tulsa contains additional information.
