Watch convection moving ESE across NW Oklahoma. Northward advancement of the warm front may be affected, but it's still probable that the front makes it near/just north of I-40. Perhaps not as far north as the HRRR progged. Highest tornado threat will be near/south of warm front. pic.twitter.com/YatO4OuxJS
