a national holiday weekend under a rain shield, hail over outdoor operations, and a shrinking but real heat index
Outdoor operations are a lead-time business, and today hands out three very different amounts of it. Silver Week in eastern Japan gets more than a day — enough to move, shorten or roof an event rather than cancel it at the gate, which is the difference between a refund and a reschedule. The SLIGHT hail risk over Oklahoma and eastern Colorado gives hours, and hail is the hazard that damages the site itself rather than just the schedule. The South-Central heat is the one easing — about 4 advisories, down from 13 — but the index still reaches about 108 °F in Middle Tennessee, and standing down a cooling plan too early is its own failure mode. In KwaZulu-Natal a Yellow Level-2 covers a single afternoon window, 13:00 to 23:59, which is about as precise as an event decision ever gets.
