Widespread wind damage in southern Illinois Friday

A widespread damaging wind event occurred in southern Illinois and parts of southeast Missouri on Friday.

    * Peak wind gusts were measured around 80 mph at several locations, including DuQuoin in Perry County and Carbondale in Jackson County. The peak gust recorded by the automated system at the Carbondale airport was 81 mph before the system failed. An observer at the airport visually observed a separate anemometer located on the rooftop reach 106 mph.  The automated system measured a sustained wind of 68 mph before failing.
    * Extensive tree and power line damage occurred in the Murphysboro, Carbondale, and Marion areas of southern Illinois and Perry and Bollinger Counties of southeast Missouri. Numerous structures were damaged in the Marion, Carbondale, and Murphysboro areas. While injuries were reported, an approximate count was not available as of late Friday afternoon. No fatalities were known as of late Friday.
    * The Williamson County airport near Marion reported a peak gust of 86 mph. There was extensive damage at the airport, including hangar buildings.
    * Wind damage extended eastward into the Harrisburg area (Saline County). The system weakened before exiting southern Illinois.
    * Damage surveys will be conducted on Saturday. Details will be available upon their completion.
    * The damaging winds were associated with the "comma head" of a bow echo. The comma head maintained unusually strong intensity after the bow echo began to dissipate. As the following radar image shows, an "eye" feature developed in the center of the comma head. The "eye" is visible as the light blue center surrounded by heavier echoes, located just north of Carbondale (near center of photo and due east of Farmington, MO). Image taken at 1:28 P.M. CDT.

Muchísimas gracias por tu aportación, Paco Yo pensaba aún que los mesovórtices asociados a SCMs, aparecían cuando estos entraban en la etapa de debilitamiento previa a su muerte. Ahora sabemos de qué son capaces estas bestias............... Qué bárbaro! Nunca antes había visto un monstruo así. Con razón hubo que adaptar los criterios de Maddox sobre los Complejos Convectivos de Mesoescala para adaptarlos a "nuestros" SCMs

En España hemos tenido esos mesosvortices en la fase de disipiación de los SCM pero allí donde hay gran inestabilidad se conforma con un mecanismo añadido de disparo de nueva conección, de forma qe se va autoregenerando.

Además de la liberación de calor latente es importante las descendencias de aire frío traseras que generan fuerte contraste térmico en caas bajas y medias, reforzando las corrientes verticales y las rotaciones.

Todo se comporta "como si fuera un pequeño bonsai de una baja profunda de latitudes medias" pero con otra dinámica, geneis y evolución.

Bye

Bye

En el estado de Oklahoma ahora mismo están de nuevo con tormentas severas, esta vez asociadas a un Sistema Convectivo de Mesoescala "un poco más normalito":

En esa línea de turbonada aprecio un ligero tono morado, al sur de la misma. ¿Es de una supercélula?
