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 Morton averaged 1.1° warmer than the 1900s. The biggest change is in January (+3.0°).
A smaller shift than in 73% of U.S. towns.
