Isolated thunderstorms are attempting to develop near the Highway 75 corridor ahead of a dryline at this time. These storms have struggled to gain intensity thus far, but there remains a chance that a storm or two may become better established through early this evening. If a storm can become established, significant severe weather will be possible, including large hail, damaging winds, and tornadoes. The main threat will be in a rather narrow corridor of eastern Oklahoma where instability is the greatest. Once storms move east of the instability axis, rapid weakening will likely occur as they approach far eastern Oklahoma. Later tonight, additional storms may develop across parts of far northeast Oklahoma and northwest Arkansas as a cold front pushes south into the area. An isolated strong to marginally severe storm will be possible, with marginally severe hail being the main threat at that time. Hot temperatures and lower humidity values behind the dryline across western Osage and western Pawnee counties will keep fire weather concerns heightened in those areas until around sunset. South winds may gust to 30 to 40 miles an hour at times overnight over the higher terrain areas of southeast Oklahoma as a strong low level jet develops. SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Local Spotter Activation May Be Needed. .DAYS TWO THROUGH SEVEN...Thursday through Tuesday.

A slight chance of thunderstorms will continue across northeast Oklahoma on Thursday, however the greater focus for storms will be farther west and north of the local region. Breezy southerly winds will continue and help maintain a risk of grassland fires across parts of Osage and Pawnee counties. Thunderstorm chances increase late Saturday with a risk of strong to severe storms. A cold front will move slowly across the region Saturday night through Sunday with an increasing risk of locally heavy rainfall and flooding potential. weather.gov/tulsa contains additional information.
