TEMPO 1719 1/2SM -RA FG indicates what?

Temporary conditions from 1700 to 1900 UTC with visibility 1/2 SM, rain and fog

Temporary conditions within the forecast period. TEMPO indicates these conditions are not constant but may come and go for a limited time. The time window shown means these temporary conditions are expected from 1700 UTC to 1900 UTC. The visibility of 1/2 statute mile is the prevailing value during that period, and the weather phenomena are light rain (-RA) and fog (FG). So the message is: for 1700–1900 UTC, there will be brief periods of very poor visibility, about 1/2 mile, due to rain and fog.
