Dense fog advisory expected to linger over Treasure Valley through Sunday

A dense fog advisory for the Boise area went into effect Saturday around 2 p.m., according to the National Weather Service.

Visibility is at less than a quarter of a mile and will stay low through Sunday morning, when it should start to clear up around 8 a.m.

The rain is pretty much done for the day, though, said Les Colin, meteorologist for the National Weather Service. Light rain or snow is predicted for Saturday night, but there will only be an occasional sprinkle through the day, Colin said.

Overnight temperatures will dip down and could refreeze roads. The low is predicted to be 28 degrees.

“Tonight we might get cold enough to get some ice back on the roads,” he said.

So Sunday drivers should take it easy.

There is some light precipitation predicted, but the biggest hazard will likely be ice.

Ski resorts are basking in the precipitation, accumulating more snow, and opening their slopes to skiiers and snowboarders.

The next storm system is predicted to move in Tuesday. Boise area residents can expect light snow. But an arctic surge is predicted for Friday.

“We have high temperatures forecasted only in the teens, and the lows would be in the single digits,” Colin said.

The dense fog meant some Delta airlines had to divert their routes away from Boise Airport, since some of those planes didn’t have the updated technology that would prepare them for landing in those conditions, but the airfield was open and taking flights, according to Sean Briggs, spokesperson for the airport.
