A cluster of showers and storms should move southward out of Kansas overnight into NE OK and move SSW before dissipating by mid morning. These storms would leave an outflow boundary draped somewhere across C OK from NW to SE. If the CAP breaks by late afternoon along this boundary and the cold front moving into NW OK, expect additional storms. Some of these would be severe with hail and wind the primary threat. However, even though the weak winds aloft are not conducive for tornadic development, I will keep an eye on how the baroclinic boundary sets up. Sometimes a storm can ingest the horizontal vorticity along these features and produce a tornado as a result, when otherwise a storm would not. So go about your Sunday routine, but keep an eye out late afternoon/evening.
