Will there be a white Christmas in store for the Inland Northwest this year? As usual this will depend on where you live. As of December 17th, the only communities with an appreciable snowpack were the valleys along the East Slopes of the Cascades. There was also snow on the ground in many of the valleys of northeast Washington and the Idaho Panhandle but many areas only had an inch or two on the ground. 

Looking ahead, little in the way of lower elevation snow is forecast this week.  Weak weather systems Monday Night into Tuesday and again late in the week may produce light snow in some of the Cascade valleys and near the Canadian border but amounts look light.  Thus for most areas, the chances of a White Christmas will come down to the weather on Christmas Eve into Christmas Day.  As of today, the NBM (National Blend of Models) is only calling for a 10% chance of 1" or more of snow mainly from about I-90 north.  The chances 1" of snow on Christmas in the lower elevations south of I-90 (Othello, La Crosse, Lewiston-Clarkston Valley) is near 0%.

For most locations the chances for a White Christmas does not look great this year, unless you live along the East Slopes of the Cascades or up in the mountains.  We will provide more updates this week.  

 

The National Climate Data Center has a nice map of the climatological odds of a White Christmas at this link.
