A four-season climate with a real, current tornado/derecho risk

Highland Park shares Illinois's statewide climate risk profile documented in illinois.js: a real, escalating 2026 tornado season (202+ confirmed statewide) plus an August 11, 2026 derecho -- a real, current homeowners-insurance cost driver, not a background-level historical risk.

A real Lake Michigan lakefront moderating influence

Highland Park's direct Lake Michigan shoreline brings a genuine lake-effect moderating influence on temperature extremes -- though this record did not independently quantify that effect this pass, and states that limitation honestly rather than inventing a specific figure.

No hurricane, earthquake, or wildfire risk

Consistent with Illinois's statewide profile, Highland Park carries no hurricane risk, no meaningful earthquake risk, and no wildfire-insurer-availability crisis -- its real weather risk is tornado/derecho and winter severity, not coastal or wildfire exposure.
