In the absence of radar data, satellite data can be utilized for warning decision-making by utilizing a suite of satellite-derived products.<\/p>\n

GREMLIN (synthetic composite reflectivity) used in tandem with OCTANE can depict an area of strengthening convection that would be capable of producing hazardous weather.<\/p>\n

In the example shown below, OCTANE indicated strong cloud top divergence and GREMLIN showed increasing reflectivity, which resulted in increased confidence that convection is intensifying (as shown in this case). As a result, a special weather statement (SPS) was issued for a strong thunderstorm producing small hail and gusty winds. This storm would initially produce half inch to nickel hail.<\/p>\n

Later on, cloud top divergence intensified further on the same thunderstorm:<\/p>\n

Eventually, this storm would produce severe hail. This demonstrates the utility of monitoring satellite trends. If you have storm reports, you can use those trends to calibrate yourself on warning-decision making.<\/p>\n
