Empirical Forecasts — Hailstone (upper Buffalo) — 2026-10-01

Hourly records: 24 — claims (≥8 %): 0, no-rise-indicated: 24, not a forecast (gauge already within reach): 0
Settled (horizon passed): 16

Each hour the engine states the calibrated chance the gauge rises to the next level within its horizon. Below 8 % it says "No rise indicated"; those hours are graded on their miss rate, not as claims. A gauge sitting just under a level gets no probability (a crossing from there is not a rise the engine forecasts). Experimental.
