Evidence / storm surfaces
How San Rafael saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for Aug 26, 2026 — this storm produced no NEXRAD point detections over San Rafael, so there is one map to show, not two.
The storm in context
Where Aug 26, 2026 sits in San Rafael's hail record.
This was San Rafael's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 1st of the 1 storms we have logged here. Radar put the day's largest stone over San Rafael at 0.5" — radar-estimated size aloft.
The Aug 26, 2026 convective day was bigger than San Rafael: the same system put hail over 440 other tracked cities, 9 of them in New Mexico. Nearest: Prewitt (18 miles northwest, up to 0.5"); Jemez Springs (90 miles northeast, up to 0.5"); Sapello (149 miles east, up to 0.75").
These maps are stills. In the app this date is one of 1 San Rafael storm date 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 San Rafael. 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 0.5" hail means for San Rafael 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.
