The outflow boundary/effective frontal boundary will drift southeastward tonight before stalling/washing out over southeast Oklahoma by Saturday morning.

LONG TERM

(Saturday Night through Friday) Issued at 1145 PM CDT Fri May 8 2026

Thunderstorms are expected to develop well west of the forecast area Saturday afternoon and track eastward toward eastern Oklahoma by the late evening hours. The severe weather potential appears to mainly be focused west of the local region through Saturday night, with a lower threat with eastward progression into eastern Oklahoma and western Arkansas. However, a cluster of strong to marginally severe storms is progged to advance into eastern Oklahoma and track eastward through the overnight hours Saturday, clearing western Arkansas by daybreak Sunday. Damaging winds look to be the main severe threat with this activity, along with locally heavy rainfall. A stronger wave and associated frontal boundary is progged to move over the region Sunday morning, likely enhancing further thunderstorm development along the boundary across northeastern Oklahoma Sunday morning. This activity will push southeastward through the day Sunday. Again, some strong to marginal severe storms will be possible, especially later in the day across southeast Oklahoma where more instability can develop.

The front pushes south of the region Sunday night into Monday, with dry and mild conditions prevailing as surface ridging builds into the region. Northwest flow aloft on the periphery of a building western ridge will continue into mid week. Another weak frontal boundary looks to move into the region Tuesday into Tuesday night with a low chance of showers or a few storms. Upper ridging shifts more over the region by Wednesday before beginning to retreat southward toward the end of the week. More zonal flow is progged to develop by the end of the week into next weekend, with a possible uptick in storm chances possible during this time. Trends show the pattern possibly becoming more unsettled, more typical of mid to late May, heading into the next week. Temperatures through the period remain near to above seasonal averages.
