| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Lexington, SC | 34° | 93° | 46" | 1.2" |
| Sulphur Springs, TX | 34° | 94° | 45" | 1.6" |

| Durant, OK | 32° | 94° | 43" | 2.0" |
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 Lexington averaged 1.2° warmer than the 1900s. The biggest change is in February (+2.0°).
A smaller shift than in 64% of U.S. towns.
Change by month
