The future progressive tense, also referred to as the future continuous tense, is formed by using the helping (auxiliary) verb “will be” followed by the present participle form of the verb (ending in “ing”). This tense shows a specific moment in the future, one that started prior to the specific moment but has not finished at the specific moment to which is referred. The specific time is usually known or understood by your readers. Consider the following examples:
Example 1: Snow will be falling when she drives to work (the snow is falling at a specific moment, but it started before that moment and continues past it).
Example 2: She will be in the middle of practice at 6:30 p.m. (at 6:30, her practice is occurring, but it started prior to 6:30 p.m. and continues past that time).
