| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Concord, MO | 24° | 89° | 43" | 10" |
| Lake of the Woods, VA | 25° | 88° | 44" | 11" |

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 Concord averaged 1.0° warmer than the 1900s. The biggest change is in December (+2.1°).
A smaller shift than in 75% 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.
How Concord compares
Against 12,954 U.S. towns of 2,500 or more (one per 5 km climate cell), with Concord’s place among Missouri’s.
