Fog settled in over the Treasure Valley Friday morning. Though it’s thick in spots, the National Weather Service stopped short of issuing a dense fog advisory due to its general patchiness, said NWS meteorologist Jeanne Allen.

Once the sun has a chance to burn it off, the fog is expected to dissipate, she said. The fog is expected to lift between 11 a.m. and noon, she said.

Commuters should take it easy on their drive. The fog, combined with temperatures dipping below freezing, will lead to slick spots on the roads. But it should clear up once the fog’s gone, Allen said.

The “rest of today looks mostly sunny once we get this fog out of here,” Allen said.

The high Friday is predicted to be around 44 degrees, according to NWS.

Saturday could see precipitation in the mountains, with up to 2 inches of snow expected to fall, but would remain a dry day for Treasure Valley residents, Allen said. The high for Boise is predicted to be 46 degrees with a low of 29 degrees, she said.

An inversion could set in Sunday with the onset of a high pressure system, Allen said.

The inversion will stick around at least through Tuesday, when another pattern could push it out. But, that system is fairly weak, and may not move the cold inversion out, she said.
