Frequently asked questions
What is the largest hail recorded on June 20, 2026 in Weld County so far?+
NOAA's MRMS radar network detected radar-estimated hail up to 1.52" in Weld County, Colorado on June 20, 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 within 60-90 days, and this page upgrades to them automatically.
Is this storm record final?+
No — this is a preliminary radar record, current as of July 13, 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 60-90 days 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 shows each radar cell where MRMS estimated hail of 1 inch or larger. 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 20, 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.
