A brief return of Gulf moisture into a slow moving frontal zone, had yielded an area of low clouds and fog to the east of Oklahoma City. At 11 am, fog was observed at Shawnee and Seminole, up through Chandler to Stillwater.
Gradual movement of the cold front will help to push the clouds and fog eastward this afternoon. Until then, fog may be locally dense, and travelers should anticipate sudden changes in visibility. The cold front itself ran from Muskogee to Purcell, to Hobart and Elk City. It was very slow moving at midday, but as an upper level trough passes, the front will begin to move more quickly southward, reaching Wichita Falls to Ada by 3 PM. There will be a wide range of high temperatures today…with 60s and 70s along the Red River, 40s along Interstate 40, and 30s in far northern Oklahoma.
