“Wet days” have at least 0.01" of rain or melted snow. “Snow on ground” counts days with 1" or more. The 30-year range is the coldest and warmest that month’s average temperature got between 1991 and 2020.
Rain and snow in Lithium
Lithium gets 45 inches of rain and melted snow a year. May is the wettest month and February the driest. Rain or snow falls on about 101 days a year.
About 182 frost-free days a year
In half of years the last 32° night comes by April 19 and the first one by October 20. That leaves about 182 frost-free days for gardens, longer than 55% of U.S. towns.
Heating and cooling a home in Lithium
Engineers use “degree days” to estimate how hard a furnace or air conditioner works. In Lithium, 79% of that work is heating and 21% is cooling.
Degree days measure how far each day’s average temperature falls below or rises above 65°, added up over a year. Source: NOAA station normals.
How Lithium compares
Compared with every U.S. town and city on TownTapestry, each counted once.
Warmer than it used to be
The last 30 years in Lithium averaged 0.8° warmer than the 1900s. The biggest change is in February (+1.7°). The shift is smaller than in 84% of U.S. towns.

How much a month can swing
A normal is an average, and real years wander around it. December swings the most: between 1991 and 2020 its average temperature ranged from 23° to 45°. October is the most reliable, staying within 9°.

Temperatures and rainfall come from NOAA’s gridded climate normals for Lithium itself (about a 3-mile square). Snow, frost dates and day counts come from NOAA’s weather station at Chester, IL (6 mi, snow) and Perryville Wtp, MO (7 mi, frost, heat and degree days). Normals are 30-year averages, not a forecast.
