DISCUSSION...Storms are forming over east-central CO, near a surface trough. This trough continues to deepen per surface observations, with convergence maximized in that area. These cells are also within the instability/theta-e axis, with southerly winds bringing warmer air northward. Objective analysis indicates 0-1 SRH near 100 m2/s2, with backed surface winds from southeast CO into southwest KS where temperatures are warming. Although the ongoing cells are farther north, the southernmost cells may eventually access the more favorable environment, with hail possible. Boundary-layer T/Td spreads are reasonable to support a brief tornado as well given the sufficient low-level shear. ..Jewell/Hart.. 09/28/2026 ...Please see www.spc.noaa.gov for graphic product...
