TownRatings’ own comparison of NOAA 1991–2020 normals, not a NOAA product: places of 5,000+ at least 150 miles away, one per state, closest on January low, July high, precipitation and snow.
| Town | Jan. low | July high | Precip. | Snow |
|---|---|---|---|---|
| Shreveport, LA | 37° | 94° | 52" | 0.9" |
| Montgomery, AL | 36° | 92° | 52" | 0.3" |
| Summerville, SC | 37° | 92° | 50" | 0.3" |
| Cusseta, GA | 36° | 92° | 50" | 0.5" |
| Greenville, MS | 35° | 92° | 56" | 0.4" |
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 Shreveport averaged 1.0° warmer than the 1900s. The biggest change is in February (+1.4°).
A smaller shift than in 80% 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. In a city of 176,000 people, part of the change is the city itself: pavement and buildings hold heat (the urban heat island).
