DISCUSSION... An elevated threat for severe weather exists from late this afternoon into the evening and overnight, focused across portions of northeast and east central Oklahoma mainly along and northwest of Interstate 44. Large hail and damaging winds will be the main severe weather hazard, although areas along and west of Highway 75 will have a limited tornado threat, especially during the evening hours. Thunderstorms that develop across northeast Oklahoma and also to the west of the area will progress eastward overnight, although the severe weather threat is expected to decrease with time and with eastward progress toward the Oklahoma and Arkansas border. Heavy rainfall and localized flash flooding could occur primarily across parts of northeast Oklahoma. Showers and isolated thunderstorms are ongoing early this morning in parts of northeast Oklahoma, with additional development possible into late morning. Although a strong storm cannot be ruled out, severe weather is not expected with the morning thunderstorms. In addition, reduced visibilities due to patchy fog in valley areas of far northeast Oklahoma and northwest Arkansas should improve by mid morning. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Activation of the Regional Spotter Network Likely. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday. THURSDAY...Thunderstorm Potential...Heavy Rain Potential. FRIDAY...Thunderstorm Potential. SATURDAY...No Hazards. SUNDAY THROUGH TUESDAY...Thunderstorm Potential...High Wind Potential. EXTENDED DISCUSSION... Shower and thunderstorm coverage will increase during the day Thursday and continue into Thursday night, due to an upper level storm system to the west. Heavy rain and flash flooding is expected to be the main concern, although a limited threat for severe weather will exist. Thunderstorm chances should end from southwest to northeast Friday as the storm system lifts northeast of the region. After a dry and hot weekend, low chances for thunderstorms return to primarily parts of northeast Oklahoma and northwest Arkansas both Sunday night and Monday night as overnight thunderstorm complexes to the north brush portions of the area. By Tuesday, an approaching cold front could bring another round of thunderstorms to the region. weather.gov/tulsa contains additional information. $$
