How We Count
This page uses published ground reports from 2016-01-01 through 2026-10-29. Coverage is partial. 473 source scopes are pending. Pending data is not a zero report count.
Hail counts at 1.00 in or larger. Wind counts at 58 mph or stronger. State days also include tornado reports.
Reports use the local civil date and clock. City pages use the city clock. State pages use each report location clock.
Exact repeated observations are counted once. Nearby reports with different times, coordinates or sizes remain separate observations.
NCEI rows are verified against NCEI Storm Events. SPC and NWS local reports are preliminary.
Radar signatures and warning polygons are not ground reports and are not in these counts.
A missing report does not show that no storm occurred. These pages show city or state exposure, not damage at an address.
This free page covers the state. It does not check a street address.
Limits
This page is not a certified record.
This page shows weather exposure, not damage or cause.
This page is not an expert opinion and it is not a meteorologist review.
Verify these rows with official NOAA and NWS records.
VectorWX is not affiliated with or endorsed by NOAA or NWS.
Radar-estimated hail size comes from MRMS MESH or NCEI nx3hail. It is an estimate of hail aloft. It is not a measurement of hail on a roof.
