Check NOAA's hail records for your address on the day of the storm

Enter the address and the date your insurer is questioning. Before you pay, you see how many NEXRAD radar hail signatures fell within 1, 3 and 5 miles that day and the nearest spotter report. The $19 PDF lists every one with its time, size, distance and NOAA record reference, plus ten years of hail history at the address.

A real example: the City of Arlington's municipal office tower, 101 S Mesquite St, Arlington, TX, on Monday, May 27, 2024. Rings at 1, 3, 5 and 10 miles.

Radar signatures within 1, 3, 5 mi: 1 / 10 / 26
Of those, rated a 100% chance of hail: 1 / 6 / 9
Largest expected size within 5 mi: 2.75 in
Nearest signature: 1.0 mi SE, 7:31 pm CDT
Spotter reports within 10 mi: 35, up to 3.25 in
Days with a 100%-rated cell within 3 mi, prior 10 years: 38

Each radar hit near your address, with the reference NOAA filed it under

These are the 26 hail signatures NOAA's radars logged within 5 miles of the City of Arlington's municipal office tower on the evening of Monday, May 27, 2024, as they appear in the sample report; 9 of them were rated a 100% chance of hail. Anyone can look up a row by its radar, cell and scan time.

From the sample report. Distance and direction are measured from the address to the storm cell's plotted position.

1, 3, 5 miEvery NEXRAD hail signature within 5 miles for the seven days around your date: local time and UTC, distance and direction, maximum expected hail size, hail probabilities, radar and storm cell.
10 miEvery Storm Prediction Center hail report within 10 miles that week, with the size, the place and the National Weather Service's comment text as published.
MapThe signatures on your date, sized by expected hail size, the path each storm cell took past the address, and the spotter reports around it.
10 yearsEvery day a storm cell within 3 miles was rated a 100% chance of hail, over the ten years before your date and since, with the largest expected size and the nearest distance. If the insurer points to an earlier storm, you can see which ones there were.
LinksThe NOAA queries that return the same rows, so an adjuster can open them.

Radar signatures and spotter reports answer different questions

The report carries both, because each covers what the other misses.

Radar hail signature

For every storm cell at every radar scan (about every 4 to 6 minutes), NEXRAD's Hail Detection Algorithm estimates the chance of hail, the chance of hail 3/4 inch or larger, and the largest hailstone to expect. It covers storms no one saw, including at night and between towns. The report lists every cell the algorithm rated, from a 10% to a 100% chance of hail, with both probabilities on each row, so a weak cell is never mistaken for a certain one.

It is an estimate from radar, placed at the core of the storm cell. It is not a stone measured at your house.

Spotter report

A trained spotter, an emergency manager or a member of the public told the National Weather Service they saw hail of a given size at a given place and time. The Storm Prediction Center logs the reports the National Weather Service passes on, usually the same day.

It is a ground observation, but only where someone was watching and reported it. The daily logs are preliminary and NOAA can revise them.

Neither record says whether a particular roof was damaged. That takes a roofer or adjuster looking at the roof.

Recent hail days in the metros we map

Each storm date has its own page with every spotter report, the towns hit and what radar recorded inside the metro. These are the latest.

Questions before you buy

Does this prove hail damaged my roof?

No. It shows what NOAA recorded: where its radar algorithm placed storm cells it rated for hail, how likely it rated hail and what size it estimated, and what spotters reported nearby. Whether a roof was damaged is a question for a roofer or adjuster who inspects it. The records can show that a hailstorm passed close to the property on the date you give, which is usually the first question an insurer raises.

Which dates can I check?

Any date from January 1, 2005 until NOAA has published the day, which usually takes one to three days after a storm. The free check tells you if a date is too recent.

What if NOAA recorded nothing near my address?

The free check shows the counts before you pay, so you will know. If there were no signatures within 5 miles, the report would document that and the ten-year record, but it cannot show hail NOAA did not record.

What if NOAA's archive is missing my date?

NOAA's radar hail archive has occasional gaps: whole days with no records anywhere in the country. We check for this before you pay and will not sell a report for a date in a gap.

Why does every row show two times?

NOAA records time in UTC. The report converts it to your local time, using the time zone the National Weather Service assigns your county, and shows both so they can be matched to NOAA's files.

Can my adjuster check the numbers?

Yes. Each radar row carries its radar, storm cell and scan time, each spotter row its Storm Prediction Center file and time, and the report prints the NOAA links that return the same rows.

Is this an inspection or an adjusting service?

No. It is a compilation of public NOAA records. We do not inspect roofs, estimate damage, advise on claims or deal with insurers for you.

How do I get the report, and what if it does not arrive?

The PDF downloads on the page you return to after paying and is emailed to you, usually within a minute. If it does not arrive or cannot be built, email [email protected] and we will deliver it or refund you.
