Forecasters are once again engaged in warning operations within the EWP's evening activities. Bill Bunting (MIC DFW) is currently using the PGLM instantaneous flash extent density, as well as the Nearcast differential theta-e products while issuing warnings for storms over NW OK (see image above). Like forecasters from previous weeks, the Nearcast differential theta-e field provides information on near-storm convective instability and can provide the forecaster with confidence on whether or not the storms are expected to intensify or dissipate. Currently the PGLM is showing healthy flash densities, while the NLDN is only showing sparse CG activity within the storms.

Utilizing PGLM and Nearcast in warning ops
