Patchy fog and freezing fog has developed this morning across portions of eastern Oklahoma and northwestern Arkansas. The fog is most dense in and near valleys in the terrain of far eastern Oklahoma and northwest Arkansas where visibility was locally reduced to less than one half mile. Freezing fog will likely result in some slick spots on bridges and overpasses where the fog is most dense. Conditions will improve by late morning, with sunny and warmer conditions expected. The next storm system to affect the Southern Plains will translate down the west coast and into the Southern Rockies tonight through Tuesday. Moisture will be pulled back into the area ahead of this system, resulting in increasing shower and thunderstorm chances Tuesday and Tuesday night. The system will move through the area on Wednesday spreading widespread showers and thunderstorms across eastern Oklahoma and northwest Arkansas. At this time, there appears to be some severe weather potential and flooding could once again become a concern.
