Green Bay hail storm history
Brown County·NOAA NCEI Storm Events Database·~75-day publication lag
Green Bay is located in Brown County in northeast Wisconsin along the Fox River corridor, a region particularly susceptible to hail damage during severe storm seasons. The area's position near the Great Lakes and exposure to storm systems tracking from the southwest creates conditions favorable for hail formation, especially during the warmer months when atmospheric instability peaks.
Check if your roof was damaged by recent hail
Hail activity in Green Bay peaks during June and July, when warm Gulf moisture moves northward and collides with Great Lakes-influenced weather boundaries. May and August also see elevated hail risk. Storm systems approaching from the southwest produce the most intense hail events in this region, making late spring and mid-summer the critical periods for homeowner preparedness.
