NWS warnings in force right now - the only feed here that fires before the hail lands. What a warning claims is not what fell.
Filtering by size excludes warnings that state no hail size — 37% of them do not. They are silent on the matter, not below your threshold.
No warnings at or above that size
The feed answered - this is a quiet sky at that threshold, not a failure. Warnings that state no size are excluded from a size filter by design.
A warning is a forecast of what a storm may do, issued in a hurry. RADAR INDICATED means a computer inferred hail aloft; OBSERVED means a person saw it. Only the second is ground truth, and they are never averaged together.
