What time will it freeze?

weather.gov is especially useful in the winter. If it's going to get below freezing, you can see the predicted time of day that will be below freezing, so you can know when to leave the water dripping or running slowly.

Go to the weather page for your location, like : Duluth, GA

Near the bottom of the page, click on the menu item or picture “Hourly Weather Graph” to see a graphic representation of the weather forecast by hour, including temperature.

To see a text chart with the temperatures, click on the graph above, or on your main page, click on the menu item “Tabular Forecast”, which is right below the “Hourly Weather Graph” menu item.
