Preliminary radar record — NOAA MRMS
September 6, 2026 Larimer County, CO Hailstorm
On September 6, 2026, NOAA MRMS radar estimated hail in the 1.5–2″ size class in Larimer County, Colorado, across 34 radar cells. Radar-estimated MESH ≥1″ is preliminary; size is a class, not a measurement, and this is not a damage outline.
Peak radar-estimated hail size: 1.6".
On September 6, 2026, NOAA MRMS radar detected radar-estimated hail up to 1.6" in Larimer County, Colorado — 34 radar cells on September 6, 2026. Source: NOAA Multi-Radar/Multi-Sensor (MRMS) MESH, via HailScore. Data current as of September 7, 2026.
Larimer County has 50 NOAA-verified hail days on record since 2015. The largest measured 2.5".
For scale, the biggest on record: June 17, 2025 — 2.5" hail (NOAA ground-verified).

Source: NOAA Multi-Radar/Multi-Sensor (MRMS) MESH. Coordinates are radar-grid cell centers — preliminary, not ground-verified. Sizes are a class, not a measurement — MESH is tuned so most measured hail comes in at or below the estimate.
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.

Frequently asked questions
Did it hail in Larimer County, Colorado on September 6, 2026?+
On September 6, 2026, NOAA MRMS radar estimated hail in the 1.5–2″ size class in Larimer County, Colorado, across 34 radar cells. Radar-estimated MESH ≥1″ is preliminary; size is a class, not a measurement, and this is not a damage outline.
What is the largest hail recorded on September 6, 2026 in Larimer County so far?+
NOAA's MRMS radar network detected radar-estimated hail up to 1.6" in Larimer County, Colorado on September 6, 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 September 7, 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. MESH is tuned so that roughly 75% of measured hail comes in at or below the radar estimate, so read a size as a class (within about one tier), not as a measurement.
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 September 6, 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.
