Gray means timing is unknown: infer next-season timing from documented periods, not from this gap. Blue requires an explicit missing report followed by a later finite report. × means explicit missing with no later value observed, or no value anywhere in the inspected history; it does not prove permanent absence.
X-axis: the Saturday week the observation describes. Y-axis: the nominal Wednesday forecast round; later rounds are higher.
T−0 is the diagonal boundary: the Saturday immediately before that Wednesday, four days earlier. On the same row, one cell left is T−1 (the previous Saturday), and two cells left is T−2. Cells to the right are future observation weeks and are white.
For Wednesday January 14, 2026, T−0 is Saturday January 10, and T−1 is January 3. Follow a column upward to see when that same observation became available.
Holiday extensions change the actual cutoff, but keep the same Saturday and nominal Wednesday row. Hover shows the actual cutoff. After the final observation week shown, T−0 lies beyond the right edge.
States outside native coverage are excluded from aggregate view but selectable individually. Missing reports may reflect suppression or withdrawal. Archives cannot establish that unknown values were genuinely unpublished. No lag is inferred in this evidence view.
