| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Arlington, TN | 31° | 91° | 55" | 2.8" |
| Huntsville, AL | 31° | 90° | 56" | 2.4" |

| Seneca, SC | 32° | 89° | 54" | 2.2" |
Temperatures and rain come from NOAA’s 5 km grid, so each town gets its own value. Snow and frost-free days come from the nearest weather station, so neighbors often share them.
Warmer than it used to be
The last 30 years in Arlington averaged 0.8° warmer than the 1900s. The biggest change is in February (+1.6°).
A smaller shift than in 90% of U.S. towns.
Change by month
The two periods overlap (1991–2000 is in both), which makes the gap a little smaller than it would be between separate periods.
