Winters are cold and snowy, with highs often in the upper 20s to mid-30s°F and lows that regularly dip into the teens. Annual snowfall is substantial, frequently exceeding 50 inches, as cold air masses interact with the elevated terrain to produce persistent accumulation from December through March.
