A new winter storm system could bring up to five inches of snow overnight to the Treasure Valley. Stephen Parker with the National Weather Service in Boise says temperatures for this storm won't dip much below freezing in the Valley.
But snow accumulations and wind forecast into tomorrow could make commutes difficult in the morning.
"The winds are going to increase as this storm continues and as we get into tomorrow afternoon the winds are going to get into wind advisory criteria," says Parker. "That’s going to cause some additional drifting and blowing."
Those winds could reach 40 miles per hour in Mountain Home tomorrow afternoon. The National Weather Service has issued a winter storm warning for McCall and Idaho City, where snow could add up to more than half a foot. Twin Falls could see one-to-two inches of snow.
Parker forecasts the heaviest snow will fall in the Boise metro between 8 p.m. tonight and 6 a.m. tomorrow. He says the decision to close schools is up to the individual districts. But he wouldn't be surprised if some districts decide to cancel class tomorrow.
"If we get near four inches overnight in the Boise metro area, that will obviously impact the schools here a lot," Parker says. "And in McCall the school districts will be impacted a lot. But it may not be as much in the lower Treasure Valley."
But Parker cautions that with storms like this, accumulations are difficult to forecast. He says temperatures in the Treasure and Magic valleys will hover around freezing, which may mean rain could fall at the lowest elevations.
