No. I've lived in the Seattle-Tacoma Metropolitan Area for quite a while. We might get black ice on the roads or frost on the lawn, but snow is rare. See the link below for Seattle weather information for the month of November.
Mt. Helena once erupted, and the explosion was 20 x the explosive power of an atomic bomb.

According to the National Parks Service, the average annual snowfall over the last thirty years is 137.5 inches (unless I added wrong).
Sioux Falls, South Dakota gets an annual average of 44 inches of snowfall per the National Climatic Data Center. The Mt. Rushmore National Memorial gets an annual average of 52 inches of snowfall per the NCDC.
By mt Helena I assume you mean St. Helena, the island off the coast of Africa. Napoleon Bonaparte died at St. Helena.
From Wikipedia (http://en.wikipedia.org/wiki/Climate_of_the_United_States): "On average, the mountains of the western states receive the highest levels of snowfall on Earth. The greatest annual snowfall level is at Mount Rainier in Washington, at 692 inches (1,760 cm); the record there was 1,122 inches (2,850 cm) in the winter of 1971-72. This record was broken by the Mt. Baker Ski Area in northwestern Washington which reported 1,140 inches (2,900 cm) of snowfall for the 1998-99 snowfall season." Otherwise, as for actual cities, the top five for average annual snowfall, according to the National Oceanic and Atmospheric Administration (NOAA), are: Marquette, Michigan Sault Saint Marie, Michigan Syracuse, New York Caribou, Maine Lander, Wyoming Interestingly, Flagstaff, Arizona is #6.
