Weather Skip notifications

Every evening I get the following notification:

Saturation Skip for Irrigation…
Shrubs & Trees will be skipped. Weather Intelligence has calculated that your soil has enough moisture.

Followed the next morning by:

Weather Skip Update…
Shrubs & Trees will not be skipped because the weather has changed.

I live in the Phoenix AZ area and we haven’t had rain or been forecasted for rain for weeks. It doesn’t harm anything, but I’m curious about why I get them.
