A real, warm, humid summer season

July, the warmest month, averages a 76.3°F mean temperature with highs commonly reaching into the mid-80s°F, alongside real, genuine humidity -- warm, humid, and wet summers per this pass's sourcing.

A real, cold but not extreme winter

January's average low ran approximately 31.1°F, with the typical annual temperature range spanning approximately 23°F-85°F (rarely dropping below 9°F or exceeding 93°F) -- a real, genuine four-season climate without the deep-freeze extremes of more northern markets.

Genuinely light annual snowfall

Lancaster averages only about 20 inches of snow annually, spread primarily November through March -- genuinely light compared to Great Lakes lake-effect markets documented elsewhere in this project (for example, Petoskey, MI's ~121 inches), reflecting Lancaster's inland, non-lake-effect Mid-Atlantic setting.
