How to read this

Rain is the average depth over the whole watershed, in inches of water (rain plus melted snow), not what fell at one spot.
Normal is the average total for the same dates in each year from 1991 to 2020, the standard climate normal. (A middle value would mislead here: in a dry season most years have almost no rain in a given week, so a wet week would look like thousands of percent of normal.) Wetter than N% of years places this period among those 30 years, and does not depend on how normal is calculated.
A PRISM day is the 24 hours ending at 12:00 UTC (about 5–6 AM Mountain), so a day's value is mostly the previous day's rain. The newest days are provisional: PRISM revises about the latest six months.
Watersheds the precipitation grid covers only partly say so, and their numbers are averages over the covered part. A few New Mexico watersheds that lie mostly in other states or in Mexico are left out, because the precipitation grid does not cover them.
Short periods swing widely: a single storm can make a 7-day total many times normal, while a year smooths storms out. Periods end on the latest PRISM day.
