It's a fair bet that crews with the Ada County Highway District will be spending a part of their Christmas trying to keep roadways clear so that residents can make their way to Midnight Mass and family gatherings as the Treasure Valley gets a blast of winter weather, practically guaranteeing a chance for a White Christmas.
The National Weather Service office in Boise is forecasting an 80 percent chance of precipitation on Christmas Eve, with new snow accumulation of around an inch. Things get cold overnight and Christmas Morning should also see more snow. While Friday, Dec. 26, should see clear, cold conditions, more snow is in the forecast for the final weekend of 2014.
"The Highway District's crews will remain on-call over the holiday," said an ACHD release, issued Tuesday afternoon. "Our on-call supervisors will monitor the weather hourly, and crews will be ready to react accordingly."
One major concern is that rain (which is expected to preclude the snow) could prevent crews from pretreating the roads with magnesium chloride—it washes away—but the ACHD says if the snow that follows creates icy conditions, sand and//or salt will be used on area roadways.
