Evidence / storm surfaces
How Altoona 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.
Radar signature field The point detections NEXRAD recorded overhead. Each signature marks where the radar saw hail aloft — it is a detection, not a stone measured on the ground.
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.
The storm in context
Where Jul 8, 2026 sits in Altoona's hail record.
This was Altoona's 4th recorded hail day, arriving 4 days after the Jul 4, 2026 storm. By severity it ranks 7th of the 11 storms we have logged here. Radar put the day's largest stone over Altoona at 0.75" — the largest NEXRAD radar signature.
The Jul 8, 2026 convective day was bigger than Altoona: the same system put hail over 908 other tracked cities, 34 of them in Florida. Nearest: Astor (7 miles north, up to 1.5"); Deland (12 miles east, up to 2"); Sorrento (15 miles southeast, up to 1").
These maps are stills. In the app this date is one of 11 Altoona 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 Altoona. 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.
Near the severe threshold
What 0.75" hail means for Altoona roofs.
A signal this size sits near the National Weather Service severe threshold. Aging shingles and soft metals such as vents, flashing, and gutters may be more vulnerable; roof age, wind, and material condition all matter, and only an inspection can confirm damage.
