Evidence / storm surfaces
How Hartley saw the hail — from two instruments
The maps here read the same storm from two angles — point detections from NEXRAD, and modeled hail size aloft. Where the two disagree is informative: it marks where estimated size outran the signatures, or trailed them.
Radar signature field Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
Only the NEXRAD radar-signature surface resolved for Mar 5, 2026 — the estimated-size swath had no hail signal to model for this storm, so there is one map to show, not two.
The storm in context
Where Mar 5, 2026 sits in Hartley's hail record.
This was Hartley's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 13th of the 14 storms we have logged here. Radar put the day's largest stone over Hartley at 0" — radar-estimated size aloft.
The Mar 5, 2026 convective day was bigger than Hartley: the same system put hail over 343 other tracked cities, 73 of them in Iowa. Nearest: Primghar (23 miles southwest, up to 1"); Mapleton (78 miles south, up to 0"); Lake City (84 miles southeast, up to 1").
These maps are stills. In the app this date is one of 14 Hartley storm dates on a live map — both surfaces, the reports, and a replay — and the same map is where you draw the swath. This page rebuilds nightly.
Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
No ground reports were filed with the National Weather Service for this storm over Hartley. That is common: a report depends on someone being there to see it and take the time to call it in. The radar surfaces above are the record here — the storm was detected from above even though no one on the ground logged it.
Below the severe threshold
What 0" hail means for Hartley roofs.
Radar signals under three-quarters of an inch stay below the National Weather Service severe threshold and generally indicate lower roof risk. Older or already-worn materials can still show effects, but radar alone cannot determine whether a specific roof was damaged.
