Specific Job Task Skills and Knowledge:

Task 4.1: Determine buoyancy and shear-related characteristics of the mesoscale environment for the purpose of anticipating potential convective storm types through the use of upper-air observations and model output (i.e., hodographs and Skew-T diagrams).

Task 4.2: Apply conceptual models of cloud microphysics, convective mesoscale processes, and storm life cycles for the purpose of identifying convective storm types and associated hazardous weather threats in the 0 - 6 hour time frame.

Task 4.3: Using all available in-situ and remote-sensing observational data, numerical model data, and SPC guidance to maintain a high level of situational awareness with respect to the evolution of mesoscale boundaries, buoyancy fields, vertical wind shear profiles, storm movements/interactions, and existing watches, warnings, and advisories.

Task 4.4: Evaluate convective initiation aspects in the forecaster's CWA (i.e., potential timing and location) and collaborate with SPC for appropriate convective watch issuance, if necessary.
