The Storm Prediction Center's Day 1 outlooks for September 22, 2026, consistently showed no tornado risk areas, reflecting limited deep-layer shear despite moderate instability and steep low-level lapse rates across the Southeast and Utah. A diffuse cold front and mid-level trough supported marginal severe thunderstorm potential focused on damaging winds and isolated hail, but disorganized storm modes and weak vertical wind profiles suppressed organized rotation. National Weather Service discussions highlighted 20-30% thunderstorm coverage with primary threats of 50-60 mph gusts in areas like Charlotte, Atlanta, and Birmingham, consistent with historical late-September patterns of low tornado frequency. Updated model runs and SPC briefings through the day reinforced this assessment ahead of any resolution criteria for city-specific risk.
