Convective outflow boundaries emanating away from thunderstorms are generated as cold, dense air descends in downdrafts then moving outward away from the convection to produce a mesoscale cold front also known as a gust front. Some gust fronts can be completely harmless or may be a precursor for an encounter with severe turbulence and dangerous low-level wind shear. The direction of movement of the gust front isn’t always coincident with the general motion of the thunderstorms. If the gust front is moving in advance of the convection, it should be strictly avoided. The pilot’s best defense is to recognize and characterize the gust front using METARs, ground-based radar and visible satellite imagery. In this workshop you will learn how to identify the presence of a dangerous gust front on both the visible satellite and NWS NEXRAD Doppler radar.
