We’re monitoring a few showers/weakly electrified storms over N-central Idaho. Using the cloud top cooling product, the focus for cooling was found to be along the northeastern fringe of that cluster. Using VIS imagery and keeping strong SW-erly shear in mind, the northeastward blowing cirrus shield (increasing in strength due to strengthening convective activity) caused the strongest signals for cooling (e.g. -20K/15min) along the NE fringe of that cluster. However, the most healthy looking cells eventually evolved just to the south of the cirrus shield, where some clearing occurred. It seems like this “messy situation” with rapidly clustering storms may mask local areas with better conditions for initiation.Reflectivity data beneath the cloud top cooling product.
