Question:  In Steamboat, is the snow accumulation during December different during La Niña Years?

In September, 2017, NOAA issued: La Niña is likely (exceeding ~80%) through the Northern Hemisphere winter 2017-18, with a transition to ENSO-neutral most likely during the mid-to-late spring (http://www.cpc.ncep.noaa.gov/products/analysis_monitoring/enso_advisory/ensodisc.shtml)

According to Golden Gate Weather (http://ggweather.com/enso/oni.htm), La Niña Years can be ranked as strong, moderate, or week depending upon measured pressure differences.

We categorized and graphed the snow accumulation in Steamboat Springs (snow data from NCDC – National Climate Data Center) as strong, moderate or weak.

Snow depth in Steamboat Springs typically increases through December (all years).  Interestingly, during La Niña years the snow accumulation during the first part of December is lower than average.
