Patchy fog at sunrise in the sheltered valleys and near the rivers of the Inland Northwest has forecasters warning drivers to be cautious in those areas.
Once the sun rises and begins to warm the air, the fog should dissipate.
The entire region is expected to get another warm day with near-summer-like highs mostly in the 70s. Spokane and Coeur d’Alene are expected to warm to 74.
Higher air pressure is in control of the weather today, but a low pressure region to the south may bring clouds tonight and Thursday and a risk of showers on Thursday in North Idaho and far Eastern Washington.
Highs will drop back to the 60s on Thursday through Sunday.
The chances of precipitation continue on Saturday at 30 percent and Sunday at 60 percent with the approach of another storm system from the North Pacific Ocean.
Mild air from the southwest will cover the region ahead of an expected cold front on Sunday.
Cooler weather in the 50s is likely on Monday. Frost is not likely between now and Tuesday, forecasters said.
At 7 a.m., it was 43 at Spokane International Airport, 42 at Felts Field, 46 in Coeur d’Alene, 43 in Deer Park and 43 in Pullman.
