Springfield hail storm history
Sangamon County·NOAA NCEI Storm Events Database·~75-day publication lag
Springfield sits in Sangamon County in central Illinois, a region where relatively flat terrain allows spring storm systems to maintain intensity as they track northeast across the state. This geographic position places Springfield in a corridor where hail-producing thunderstorms develop regularly during the spring months.
Check if your roof was damaged by recent hail
Hail in Springfield follows a predictable seasonal pattern, with the highest risk concentrated in April, May, and June. May is typically the most active month for hail production in the area. Secondary activity occurs in March and July, when late-winter and early-summer storm systems occasionally produce severe weather. The spring peak reflects the collision of warm, moist air from the Gulf of Mexico with cold air masses moving south from Canada—a dynamic that creates favorable conditions for hail development across central Illinois.
