Rain and usual are in inches. Usual is NOAA’s daily normal at each station, added up over the days that station reported. A station with no NOAA normal shows none. Each county page has the month by month table and how the station was picked.
Counties without a page
These 2 counties have no station inside them that reported at least 90% of the days in 2026 so far, so they get no page. A missing day is not a dry day, and a total with too many of them would read low. Next to each is the nearest county that has one.
