| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Dickson, OK | 31° | 94° | 40" | 2.7" |
| Hillsboro, TX | 36° | 95° | 39" | 0.9" |

| Milledgeville, GA | 34° | 93° | 47" | 0.6" |
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 Dickson averaged 0.3° warmer than the 1900s. The biggest change is in January (+1.4°).
A smaller shift than in all but 76 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.
How Dickson compares
