Rain changed to snow late on November 17th, and wet snow accumulated up to 9.5 inches through November 18th. Northwest winds gusting as high as 56 mph combined with the falling snow to lower visibilities to below a quarter mile at times, making travel difficult, especially since most of the storm occurred at night. Wind chills were driven down into the teens, not an unusual level for mid November. However, the change to colder weather was sudden, as unseasonably warm weather had brought daytime temperatures as warm as the 60s and 70s within the previous five days.
