On mobile, simply tap on the overflow menu button + More button from within the post and select Add Weather.

Your project zip code pulls in the current weather, but if necessary you can change the overview (ie, “Cloudy” to “Partly Cloudy”) as well as the temperature.

NOTE:
Weather is only provided in Imperial Units (Fahrenheit)

In the weather screen you can see the Zip code for your project and you can either refresh the data or enter the weather manually by selecting the weather conditions icons and typing in the Temperature, Humidity and Wind.

Once you are ready click the check icon on the top right to save the changes.

On the web, click on the existing post and tap on the Add weather button at the bottom of the comment box. Here you’ll have the option of updating the condition, temperature, humidity, and wind speed. Press Update, the weather will be added to the post as a comment reply.
