A stationary front laying west to east over eastern Washington and north Idaho on February 17th developed into surface low pressure and finally an Arctic cold front which sagged southward through the region. A fetch of Pacific moisture fed into the surface low and enhanced into a period of moderate intensity snow during the day of February 17th and into the morning of the 18th. Heavy snow accumulations resulted over much of north Idaho before very dry Arctic air descended into the region behind the front and ended further precipitation.
