Radar

Real radar, not a screenshot

NEXRAD Level 2 decoded directly on your phone, a CONUS composite for the big picture, a full animation transport, and color tables you can swap or import.

Single-Site Radar

NEXRAD Level 2, decoded on-device

Spotter Tools Pro decodes raw NEXRAD Level 2 archive files directly on your phone — no third-party tile server in between, and no degraded composite resolution.

Pick a WSR-88D site (or let the app choose the closest one) and view three products at full radial resolution.

  • Reflectivity (BR) — base reflectivity for precipitation intensity
  • Velocity (BV) — base velocity for rotation and outflow
  • Correlation Coefficient (CC) — debris signature and hydrometeor class

Velocity & CC

Rotation, outflow, and debris in one tap

Switch between BR, BV, and CC instantly to confirm rotation, mark outflow boundaries, and check for debris signatures during a tornado event — without leaving the map.

Animation

Full radar transport bar

Loop the past several volume scans with the controls you'd expect from a desktop radar app — but built for one-thumb use in the truck.

  • Play / pause and step forward / back frame by frame
  • Drag the timeline scrubber to any frame in the loop
  • Pick playback speed — slow walk-throughs or full-pace loops
  • Pick frame count — short loop or long history
  • Background frame loading with progress so you know when it's ready

Color Tables

Sixteen built-in palettes — and your own

Spotter Tools Pro ships with sixteen GR2Analyst-style .pal color tables for Reflectivity, Velocity, and Correlation Coefficient.

If you've already got a palette you like, drop the .pal file in and it just works — same parser, same gradient logic.

  • Reflectivity: 2004 LaCrosse, Apocs, Ben, Reflec 1, Viper HD, Macdonald-Emmerson
  • Velocity: Alpha, A Mix of 2, AWIPS Evans, Force, GRL3 v2, Velocity 1
  • Correlation Coefficient: AWIPS RHO, KK, CC 1, WKRN Nashville
  • Import any GR2Analyst-format .pal file from device storage
  • Per-product selection — different tables for BR, BV, and CC at the same time

Power-User Controls

Overlay opacity, clutter masks, and gate filters

Tune the radar overlay to match the way you read radar — without compromising defaults that already work for most spotters.

  • Overlay opacity slider so the basemap stays legible underneath
  • Reflectivity clutter mask to surface ground clutter, AP, and biologicals when you want them
  • Velocity clutter mask off by default — preserves debris signatures the way RadarOmega does
  • Per-product gate filters for Reflectivity, Velocity, and Correlation Coefficient

Storm Cell Picker

Tap a cell, see the numbers

Tap any storm cell on the radar to read its identifier and key attributes — useful for cross-referencing the cell against an SPC mesoscale discussion or warning text.

Composite

CONUS mosaic for the big picture

When you're trying to spot the next play across the Plains, the single-site view is the wrong tool. Toggle the composite radar layer for a full-CONUS reflectivity mosaic with selectable sources.

Composite and single-site can run side by side — single-site for tactical analysis, composite for situational awareness.

More than just radar

Pair the radar with smart push alerts that fire even when the app is closed, full NWS / SPC overlays, and one-tap severe weather reporting.
