82MIN BEFORE THE WARNING
TIMA's continuous tracking layer locked onto this storm complex at
20:02Z, held it at up to 100% signature strength,
and was carrying two 99% tracks at the warned location when
Environment Canada issued its tornado warning at 21:25Z.
First 90%+ score: 20:34Z — 50 minutes of lead.

Timeline
First track lock on the storm complex (continuous MRMS az-shear tracking, CONUS-wide layer, no warning trigger involved).
CNN signature score first exceeds 90% — sustained near 97–99% from here on.
Environment Canada issues a tornado warning for the Lilac — Richard — Speers corridor. Two TIMA tracks at 99% sit inside the warned area.
Honest notes
One storm, several track IDs. The current tracker fragments a wide
mesocyclone region into short track segments (all segments are shown and
listed below); the lead-time claim is therefore system-level — the storm
complex never left the board — not a single unbroken track.
What this is not: a warning system. TIMA scores radar
signature strength for situational awareness. A low score never means safe;
official warnings apply regardless of any number shown here.
