Boise forecast | Snow in mountains, cold temps for Christmas


Snow dusted Boise last week. Will a cold front bring snow in time for a white Christmas?

The National Weather Service’s Boise office on Tuesday issued a winter weather advisory for the mountains surrounding the Treasure Valley, calling for up to a foot of snow. But will Boise have a white Christmas, too?

The weather advisory forecasts 4 to 7 inches of snow in the mountains above 5,000 feet, with up to a foot of snow possible at higher elevations from Wednesday afternoon to Friday afternoon. Down in the valley, conditions will be noticeably less wintry.

“We’re not expecting heavy snow in the next few days in the valley,” said Stephen Parker, a National Weather Service Boise meteorologist, in a phone interview. “But we have some hope for a white Christmas.”

A cold front Thursday will usher in cooler temperatures, though the high on Friday and Saturday — Christmas Eve and Christmas Day — is expected to reach 40 degrees. Parker said cooler temperatures higher in the atmosphere mean any precipitation will fall as snow. If that snow falls Friday evening, it could stick around on Christmas morning until temperatures warm.

Parker said an “extended cold period” is on the way next week. The forecast for next Tuesday is a high of 31 degrees with overnight lows potentially falling into the teens.

The winter weather advisory urges travelers to use caution, warning that roads will likely be slippery and travel could become difficult.
