Rain begets rain, dry begets dry.
There's not enough rain in the 7 day to slow harvest but a day or so. PLUS, lets remember, they struggle to get 3 days out right.
The real indicator is I rebuilt a pond, no way it's raining for a while, just plan on it. :)
Actually, I'm kinda enjoying the dry. Plenty of stuff to do with all the rain the last 2 years and other projects that I've accumulated in that time frame. Let it be dry.
