Source: NOAA Multi-Radar/Multi-Sensor (MRMS) MESH. Coordinates are radar-grid cell centers — preliminary, not ground-verified. Radar-estimated sizes carry roughly a ±0.25″ margin versus ground measurements.
Because each cell is padded before merging and small gaps between neighbouring cells are bridged, the shaded shape is larger than the cells actually measured and encloses pockets where the radar recorded nothing. Read it as the storm's approximate extent, not a cell-by-cell map: it is not a damage outline, not a claim that every roof inside it was hit, and not a circle drawn around an address. Whether a specific property was affected depends on its exact distance from the measured cells.
How the storm unfolded

Frequently asked questions
What is the largest hail recorded on June 24, 2026 in Jefferson County so far?+
NOAA's MRMS radar network detected radar-estimated hail up to 1.8" in Jefferson County, Colorado on June 24, 2026. This is a preliminary, radar-estimated figure (MESH — Maximum Estimated Size of Hail), not a ground-verified measurement. Ground-verified NOAA Storm Events records for this date typically publish 2-4 months later, and this page upgrades to them automatically.
Is this storm record final?+
No — this is a preliminary radar record, current as of August 21, 2026. It is built from NOAA MRMS radar data, which updates continuously (typically within about 2 hours of a storm). The verified NOAA Storm Events Database entry for this date, with ground-truthed observations and official event IDs, usually publishes 2-4 months after the storm. Radar-estimated sizes carry roughly a ±0.25 inch margin versus ground measurements.
Was my property in the storm area?+
The map above shades the storm's radar footprint — the MRMS cells that estimated hail of 1 inch or larger, merged into colour-coded size bands. Enter your address in the free HailScore lookup for a property-level check of the radar record against your exact coordinates — no signup required.
Can I use this preliminary record for an insurance claim?+
The radar record can help you and your adjuster establish that hail was detected near your property on June 24, 2026 — it is the same NOAA MRMS data source many industry tools use. For the date of loss itself, adjusters typically also reference the ground-verified NOAA Storm Events entry once it publishes. A professional roof inspection remains the standard first step for documenting actual damage.
