Evidence / storm surfaces
How Sparkman saw the hail — from two instruments
Mar 15, 2026 · Sparkman, AR
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.
NEXRAD radar signatures Surface resolved
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 15, 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 15, 2026 sits in Sparkman's hail record.
This was Sparkman's 1st recorded hail day — the first hail day in our records for the city. By severity it ranks 5th of the 10 storms we have logged here. Radar put the day's largest stone over Sparkman at 1" — the largest NEXRAD radar signature.
The Mar 15, 2026 convective day was bigger than Sparkman: the same system put hail over 695 other tracked cities, 131 of them in Arkansas. Nearest: Gurdon (18 miles west, up to 1"); Carthage (18 miles northeast, up to 0.5"); Arkadelphia (22 miles northwest, up to 1").
These maps are stills. In the app this date is one of 10 Sparkman 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.

Reports came from Gravel Junction — beyond Sparkman itself.
Damage-capable hail signal
What 1" hail means for Sparkman roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained 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 21, 2026.
