Winter Storm Warning for Western Magic Valley

The storm has been upgraded to a Winter Storm Warning, which is in effect from now till 5 PM Saturday (2/8/14).

The National Weather Service in Boise has issued a Winter Storm Warning for heavy snow in the Western Magic Valley, which is in effect until 5 PM Saturday (2/8/14).  The Winter Weather Advisory is no longer in effect.

  • Snow amounts: 3 to 9 inches over a 48 hour period
  • Snow levels: On the Valley floors until Saturday afternoon when it will rise to near 4,500 feet
  • Winds: Variable 5 to 20 MPH.  Some drifting will occur at these wind speeds
  • Timing: Light to moderate snow will fall intermittently from this afternoon through Saturday afternoon.  The heaviest snow will fall Friday night.  Snow will mix with or change to rain late Saturday at elevations below around 4,500 feet.
  • Impacts: Difficult travel on snow-covered roads.  Some drifting will occur, making it even more difficult for road crews to keep the roads clear.

Precautionary/preparedness actions

A Winter Weather Warning for heavy snow means that significant amounts of snow will make travel dangerous.  Travel in an emergency.  If you must travel, keep an extra flashlight, food, and water in your vehicle in case of an emergency.

Additional Information

  • Periods of snow into the weekend, especially tonight and Friday night
  • A series of moist Pacific impulses will produce periods of snow across the region.
  • The first significant impulse will move through tonight, mainly in the form of a warm front.
  • Expect a relative break in the snowfall Friday, although there will still be light snow across the area.
  • Friday night a second impulse, in the form of an even stronger warm front will move through.  This will bring the heaviest snow of the overall event.
  • Saturday will continue to see light to occasionally moderate snow across much of the area.
  • By Saturday afternoon, warm air that moves in behind the second warm front will help change snow to rain.  This will occur below around 3,500 feet in an area stretching from Southeast Oregon through the Southwest highlands and into the Magic Valley.
