A storm day on Overview is a convective day — it runs from noon to noon UTC, so late-night hail is grouped with the afternoon storm that spawned it rather than split across two calendar dates. Everything below happened inside the Mar 31, 2026 convective day. Across those footprints sit roughly 538,491 homes, and 114 ground reports were filed with the National Weather Service. The cities are listed with the biggest storm first, measured by Overview's severity score. Each row links through to that city's own storm page, where you'll find the radar surfaces, every ground report filed, and the hail footprint drawn on the map. The counts here are the size of the set of cities Overview tracks — never "every US city" — so read a quiet day as "quiet among the places we watch," not as proof nothing happened elsewhere.
