Preliminary local storm reports from NOAA's Storm Prediction Center, made by trained spotters, the public and National Weather Service offices. Not every storm is reported, reports can be revised, and a report near a property shows storm exposure, not proof of damage. A report day runs from 7 a.m. Eastern (12:00 UTC) to 7 a.m. the next day; times are UTC.
