Thunderstorms will continue to develop across eastern Oklahoma and northwest Arkansas this evening with the greater potential along and north of Interstate 40. Storm development will continue to be more scattered for the next hour or two, and then develop into a complex later this evening before weakening late overnight. The initial storms through mid evening will be capable of large to very large hail, damaging winds, and isolated tornadoes. Then, storms will transition to a damaging wind and quick spin-up tornado threat for the late evening and early overnight hours. In addition to severe potentials, a heavy rain threat will exist, with minor flash flooding possible under any storms. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...

EXTENDED DISCUSSION... Some early morning thunderstorms may linger over western Arkansas Thursday morning before moving east. Isolated afternoon storms could develop over portions of far eastern Oklahoma into western Arkansas Thursday afternoon. If a storm develops, it would have potential to become severe. More thunderstorms are expected to develop across northern Oklahoma Friday afternoon along a dryline, ahead of an upper storm system and associated surface low pressure and cold front. These storms will have a decent chance of becoming severe in an unstable and strongly sheared environment, and would be capable of producing higher-end severe weather. This includes very large hail, locally damaging wind and tornadoes. Eventually, the cold front will overtake the dryline and will force a band of storms along it, with a damaging wind threat Friday night. weather.gov/tulsa contains additional information. $$
