A low pressure system and cool front will move into northeast Oklahoma late Saturday afternoon. The atmosphere will become extremely unstable ahead of the surface low and front, with severe storms rapidly developing across northeast Oklahoma by late afternoon or early evening. More isolated severe storm development is possible to the south along the dryline across southeast Oklahoma. Supercells will initially be possible with hail to the size of softballs and destructive winds to 80 mph. A few strong tornadoes will also be possible, especially where storms can interact with existing boundaries, such as a potential outflow boundary from convection north of the region. Thunderstorms will become more linear in nature Saturday night with one or more convective bands sweeping southeast across the remainder of eastern Oklahoma and northwest Arkansas during the overnight hours. Damaging winds will become the main threat although a limited tornado threat could persist. In addition, heavy rainfall will be likely in the stronger storms and localized flash flooding could become a concern.
Memorial Day Weekend typically marks the start of popular warm season activities such as swimming, boating, and other water related sports. Make sure to brush up on water safety tips before heading out to participate in water activities this weekend.
Dangerous heat is expected again on Saturday across eastern Oklahoma and possibly west central Arkansas. Take proper precautions if you are planning on activities that will keep you outside in the heat for longer periods.
