Climate-adjusted normal temperatures for 2026 — what “normal” looks like when it’s measured against today’s climate instead of a 30-year average centered on 2005.
Powhatan County’s official normal high — the 1991–2020 average shown by weather apps — now understates the local climate by an average of 0.8°F across the year. The gap is widest in February (+1.9°F), and warming here has been fastest in winter. That places Powhatan County #1,408 of 3,136 U.S. counties for how far “normal” has drifted from reality.
1991 called. It wants its climate baseline back.

The “normal” temperature in every weather app is a 30-year average (1991–2020) — a number centered on mid-2005, two decades out of date in a warming climate. The Climate-Adjusted Normal takes NOAA’s official normal and advances it to the present using this county’s own measured warming trend.
It isn’t a forecast — it’s a more honest yardstick for what “normal” means now. Read why Nowmal exists →

The official normal is the 1991–2020 average from NOAA’s homogenized county climate record (nClimDiv). The warming trend is fit to the county’s full record since 1895 using NOAA’s published hinge-fit approach — flat before 1975, linear after — then the normal is advanced 20.5 years to 2026.
