A grey bar is the month so far, compared with the 1991–2020 median of the same days.
A PRISM day is the 24 hours ending at 12:00 UTC on its date (about 5 to 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.
