How Hennessey saw the hail — from two instruments

Mar 10, 2026 · Hennessey, OK

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-estimated hail-size map of the storm over Hennessey, OK on Mar 10, 2026 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.

Max size 0.75"

Only the radar-estimated size surface resolved for Mar 10, 2026 — this storm produced no NEXRAD point detections over Hennessey, so there is one map to show, not two.

The storm in context

Where Mar 10, 2026 sits in Hennessey's hail record.

This was Hennessey's 2nd recorded hail day, arriving 62 days after the Jan 7, 2026 storm. By severity it ranks 8th of the 17 storms we have logged here. Radar put the day's largest stone over Hennessey at 0.75" — radar-estimated size aloft.

The Mar 10, 2026 convective day was bigger than Hennessey: the same system put hail over 470 other tracked cities, 49 of them in Oklahoma. Nearest: Dover (16 miles southeast, up to 0.75"); Kingfisher (19 miles southeast, up to 0.75"); Okarche (28 miles south, up to 0.5").

These maps are stills. In the app this date is one of 17 Hennessey 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.

Timing and place names from NOAA ground reports

Read from the arrival times and locations of the NOAA ground reports, not a radar-measured storm track.

Reports came from Dover — beyond Hennessey itself.

Near the severe threshold

What 0.75" hail means for Hennessey 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.

A storm day here is a convective day — it runs from noon to noon UTC, so late-night hail is grouped with the afternoon storm that spawned it rather than split across two calendar dates. Ground reports are public-domain observations from the NOAA Storm Prediction Center. Radar tells you where to look. Only an inspection confirms damage at an address. Last updated Aug 8, 2026.
