• Winters: Generally brisk and chilly, though extended periods of extreme cold are rare. Temperatures may drop to zero or below on about 2–3 days each winter.
• Snowfall: The average annual snowfall is just over 18 inches, with minor snowfalls occurring on 5–10 days per year.
• Annual Precipitation: Averages slightly under 34 inches, with winter as the driest period and spring as the wettest.
