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 Logan averaged 1.5° warmer than the 1900s. The biggest change is in March (+3.2°).
A bigger shift than in 60% of U.S. towns.
