Wider weather episode

A moist air mass combined with a surface low pressure system to the south of the Grangeville area helped create a northerly, upslope flow pattern, which is favorable for heavy snow on the southern side of the Camas Prairie. Grangeville and Kooskia saw impressive snow fall totals in the 9 to 14 inch range over the course of 24 hours.
