Blend adjacent rays and gates instead of NEXRAD's native pie-slice shading.

Interpolate between azimuths and soften ray-stepping in the vertical slice.

Concentric range circles around the selected radar site.

Unfolds velocity that wraps past the Nyquist limit (e.g. a real +58kt gate reading as -6kt). Experimental — turn off if you see stray flipped range bins or beams.

Subtracts storm motion from base velocity to help reveal rotation and inbound/outbound couplets.

Isolates fine lines of weak reflectivity (0–25 dBZ) on the lowest tilt — outflow boundaries, sea-breeze/lake-breeze fronts, gust fronts — and traces them with a Hessian-matrix ridge detector, cross-checked against spectrum width to reject stationary ground clutter/AP. Drawn as white lines; redrawn on every new scan and cleared when switched off.

Scans for rotation couplets (velocity, RHO- and persistence-filtered) and hail cores. Hail cores get a real size estimate (MESH) and severe-hail probability (POSH) via the Witt et al. (1998) NWS/NSSL algorithm, using live atmospheric temperature data. Automated pattern-matching, not a substitute for official warnings.
