Yes, folks; it's condensation.
Now, this is a result of water (in vapor form) which is an element of the air in any home. Essentially, the contrast between warm air in your home and cold air outside will produce condensation, because the house is designed to be sealed completely. But when the temperature of the glass drops, the dew point changes. When the dew point changes, we see condensation.
Now, imagine what your chimney looks like today. It's 39 degrees Fahrenheit this morning at my house and at the office. That means, it's already getting colder outside. If we had moisture-retaining clouds this morning, we could see snow. It doesn't have to be 32 degrees Fahrenheit to snow; the drier the air, the higher the chances are that it can be warmer and snowing at the same time.
Here's an example of a chimney that was really neglected:
Simply put, there was no care given to this chimney in a reasonable amount of time. You can see moss, evidence of efflorescence, and it's obvious that this structure is in desperate need of some tuck-pointing.
