Patchy dense freezing fog has developed along the slopes of the northern Blue Mountains, especially evident in the vicinity of Cabbage Hill and Deadman Pass along I-84. Expect low visibilities to persist this morning where clouds intersect terrain. Local patchy freezing fog has also formed in northeast Oregon this morning in the wake of yesterday`s and last night`s weather system. The freezing fog may be dense at times. Dense freezing fog is currently being reported at John Day. Conditions will improve later this morning, but patchy dense freezing fog may reform tonight due to the abundant moisture and light winds.
