Present Continuous
The present continuous (sometimes referred to as the present progressive) uses the –ing form of the verb and is often used to describe something that is temporary. For example:
It’s raining
That is, it’s raining now, but it is temporary.
The past continuous (sometimes referred to as the past progressive), which also uses the –ing form of the verb is used to describe something that was temporary sometime in the past. For example:
It was raining yesterday
That is, it rained yesterday for a temporary period and irrespective of what the weather is like now, that period came to an end. (If it is still raining and hasn’t stopped, we would generally use the present perfect continuous tense and say: “It has been raining since yesterday”.)
