Regional weather. Local conditions.

A regional forecast does not make every place feel the same

Weather information often describes a broad area. Within that area, shade, trees, pavement, buildings, nearby water, weather patterns, and geography can contribute to meaningful differences in the heat people experience from place to place.

LocalCelest explains these differences carefully, without pretending to replace current forecasts, alerts, or instructions from public officials.
