Explore Significant Hail Events. Understand the Storm. Map Probable Impact.
Radar-derived hail intelligence for weather analysis, research, and post-storm field operations.
More than a radar overlay.
HailLeads combines radar-derived hail estimates, storm structure, atmospheric context, vertical hail-core analysis, and modeled hail transport to examine where significant hail may have reached the surface.
MRMS hail reconstruction
MRMS radar-derived hail estimates establish the initial hail field, with significant-hail analysis beginning at 1.75-inch grid-cell estimates.
Radar & thermodynamic support
Reflectivity structure, including measurements near the -10°C level, is evaluated alongside storm timing and thermodynamic conditions to provide additional support for significant hail signals.
Hail descent & drift
Hail-core height, atmospheric structure, descent behavior, and storm-environment winds are incorporated to estimate how hail can translate from the storm volume toward the surface.
Impact footprints
The resulting analysis is expressed geographically as storm-impact polygons, providing a practical footprint for reviewing properties, neighborhoods, roofing activity, and probable vehicle exposure.
From radar observations to probable impact footprints.
HailLeads treats a severe hail event as a physical system, not simply a collection of colored radar pixels. Each stage adds environmental or geometric context before the signal is translated into a mapped area for field review.
MRMS hail estimation
MRMS-derived hail estimates identify significant hail signals across the radar grid. The ≥1.75-inch threshold provides the starting population for the higher-resolution storm analysis.
Reflectivity at temperature
Reflectivity near the -10°C level is used to examine storm structure associated with hail-producing regions. The analysis looks for radar support around the hail estimate rather than treating hail size alone as sufficient.
Wet-bulb-zero environment
Thermodynamic profiling provides environmental context for hail descent. Wet-bulb-zero height is used as part of the atmospheric analysis surrounding the hail-producing storm volume.
Core height & launching point
Vertical storm structure is examined to estimate the altitude associated with the hail-producing core and provide a physically meaningful starting point for subsequent descent and transport calculations.
Hail descent modeling
The modeled hail path accounts for descent through the storm environment rather than assuming that the radar coordinate is identical to the eventual surface impact coordinate.
Wind-driven drift
Storm-environment winds are integrated through the modeled descent path to estimate horizontal translation before the hail reaches the surface.
From storm data to a map you can investigate.
HailLeads provides a geographic framework for exploring significant hail events, reviewing storm evidence, and identifying probable surface-impact areas.
Hail impact coordinates
Analyze probable hail-impact areas using radar-derived hail estimates, storm structure, atmospheric context, and modeled surface translation.
Storm intelligence
Review hail size estimates, reflectivity support, thermodynamic conditions, storm timing, vertical structure, and modeled drift as parts of one analysis.
Roofing, restoration & auto hail
Use significant-hail impact maps to prioritize roofing canvassing, restoration review, automotive hail response, paintless dent repair opportunities, and other post-storm field operations.
For roofing, restoration, and auto-hail professionals: identify significant-hail areas and prioritize territories for post-storm investigation and field activity.
