Rain and thunderstorm activity will remain isolated to widely scattered Saturday night through Sunday evening. Rain and storm coverage will increase substantially ahead of a potent Pacific Cold Front Sunday night through Monday night. This is the most likely time frame for steady, heavy rain.
I don't expect any organized severe Weather, but a strong to severe storm will be possible with large hail and damaging wind the primary weather hazard. Flash flooding may also become a concern in some areas, as rainfall totals could exceed two inches across central, southern, and even southwestern Oklahoma.
I bet the farmers and ranchers out there love this!
