Blowing snow (including blizzards).

Smoke, falling ash - from large forest and brush fires or local sources.

Cloud cover. 

Fire weather:  conditions favorable to spread of urban, brush, or forest fires.

Air quality / air pollution - air transport modeling, toxic torts.

Global warming / cooling; sea level rises.

Drought, rainfall / snowfall deficits.

Climatic normals and departures from normal of rainfall, snowfall, wind, or temperature.

Frequency analyses of rainfall, snowfall, wind, or temperature.

Documentation of public weather forecasts issued for given dates.

• Sun, moon, and light:
