Hail in Mountain View May 9, 2026
Both radar surfaces caught this storm: NEXRAD logged 0 hail signatures up to 2.5", and the radar-estimated size reached 2" aloft. At 2.5" — baseball — this is severe, roof-replacing hail: close to every roof inside the footprint becomes a claim candidate.

How Mountain View 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.
Where NEXRAD flagged hail as the storm passed — point signatures from the radar, which indicate hail overhead rather than confirm what landed.
The modeled maximum hail size across the swath, derived from radar aloft — the largest stone the storm could have supported, which is not necessarily what reached the ground.
Where May 9, 2026 sits in Mountain View's hail record
This was Mountain View's 2nd recorded hail day, arriving 36 days after the Apr 3, 2026 storm. By severity it ranks 2nd of the 9 storms we have logged here. Radar put the day's largest stone over Mountain View at 2.5" — the largest NEXRAD radar signature.
The May 9, 2026 convective day was bigger than Mountain View: the same system put hail over 268 other tracked cities, 106 of them in Oklahoma. Nearest: Cordell (7 miles north, up to 2.5"); Gotebo (8 miles west, up to 2.5"); Carnegie (9 miles east, up to 1.75").
These maps are stills from Mountain View's May 9, 2026 storm. In the Overview app the same surfaces are live — radar updating in real time, radar-estimated hail size as it forms, and NWS spotter reports pinned where they're filed — with a radar replay you can scrub back over any past day.

What 2.5" hail means for Mountain View roofs
Two-inch-plus hail punctures shingles, breaks skylights and windows, and dents anything soft. In the core of a footprint like this, close to every roof is a candidate for an insurance claim. Speed decides who writes those jobs.
