Dense fog advisory remains in effect for these areas through 8 am, when fog should begin to lift with visibility improving.

Zonal flow aloft will continue today with another strong upper level speed max moving into Oklahoma tonight. In response, frontal boundary will lift north to near the Red River by early evening with elevated showers and thunderstorms spreading north of the front across southeast Oklahoma and northwest Arkansas tonight.

Elevated instability/shear profiles suggest a few of these storms could produce large hail before thunderstorm activity shift east by Wednesday morning as surge of colder air moves into the region.

Cold/breezy day on tap Wednesday and especially Thursday as northerly winds persist. Active weather pattern will continue on Thursday as another upper level disturbance swings into the southern plains. Areas of light to moderate rain will likely overspread eastern Oklahoma and northwest Arkansas Thursday into Thursday night as upper system approaches.

With the extensive cloud cover/precip, expected high temperatures are only expected to climb into the mid to upper 40s across northeast Oklahoma and northwest Arkansas Thursday afternoon. It still
appears that temperatures will remain warm enough to keep precipitation all liquid before shifting southeast by Friday morning.
