Canada’s not the only place seeing painfully early snowfall this year. East Rapid City, S.D. saw their earliest recorded snowfall on Thursday. Weather records there go back to 1888. The previous earliest snowfall date was September 13, which was set in 1970.
Nearly an inch of snow has fallen thus far at the weather station in East Rapid City, but higher amounts are accumulating across western South Dakota. Eight inches has been reported in Custer, S.D., and seven inches has been recorded so far on Mount Rushmore, in the midst of “heavy snow” reports. Downtown Rapid City has seen about an inch of snow as of Thursday morning.
A winter storm warning is in effect as snow is expected to continue through the morning hours, and then diminish in the afternoon. The Weather Service is expecting four to seven inches of heavy, wet snow by the time it lets up, which could cause damage to trees and subsequent power outages.
Thursday’s snowfall is a result of the dip south that the jet stream is taking this week, bringing early snowfall as well as cooler temperatures. This is the same system that has been causing early snowfall in Calgary this week, which caused tens of thousands of power outages as a result of downed tree branches.
At least Calgarians are keeping their sense of humor. We hope our friends in South Dakota will brush off the early snow in similar fashion.
