Southwest flow aloft ahead of a low across the desert southwest will allow for moisture and instability to increase areawide. At the surface, a frontal boundary across central Oklahoma into northwest Arkansas will gradually shift south throughout the day serving as the focus for convection late this afternoon into this evening across portions of south Arkansas, northeast Texas and southeast Oklahoma. A few storms may be severe across McCurtain county this evening. Otherwise, temperatures today are forecast to average in the mid to upper 80s.

Showers and thunderstorms to linger into the overnight hours across the I-30 corridor northward as upper-level impulses within the overall southwest flow regime continue to interact with a surface low across central Texas and attached surface boundary extending into Oklahoma.

On Wednesday, atmosphere to continue to destabilize as the upper- low across the desert southwest begins to swing east into the Texas panhandle by midday. Forcing ahead of the approaching low will allow for an increased southerly jet across the ArkLaTex setting the stage for a potential severe weather event across mainly northeast Texas, southeast Oklahoma, and adjacent counties of southwest Arkansas at the time of peak heating late Wednesday afternoon and evening. Additionally, as the surface low across central Texas tracks northeast along the front, moisture will increase in the warm sector aiding the overall destabilization process. Supercells capable of producing large hail, damaging winds, tornadoes, and a locally heavy rainfall threat can be expected within any supercells that are capable of developing.
