extremes reported by individual ACIS network stations within each state
(
data.rcc-acis.org)
since Jan 1 of this year. A state's high and low may come from two different stations. Missing or
unavailable daily readings are excluded from the comparison. Raw station data can contain typos or
instrument errors — click a state name (or a
⚠ icon) to see
its top 5 stations and judge for yourself; a lone reading far ahead of the pack is flagged automatically.
