The El Nino pattern is at least partly to blame for this fickle weather.
Normally this time of year, the storm track goes into the Pacific Northwest or western Canada. When there is an El Nino, however, the Pacific storm track is much farther south.
Sunday and Monday, a bitter blast of arctic air will surge southward through the prairies of central Canada, but that intense cold is not coming to southwestern British Columbia. However, it is possible that rain and mountain snow return to the Olympic sites around the middle of next week.
