- A bright anvil is the evidence of an explosive storm updraft phase
- W020542S
- The evidence of a former explosive storm updraft phase can be seen in the bright anvil lobes that surround a weakening shower. The original burst arrived at the inversion where it slowed and began spreading out like an upside down haboob effect. The toes, or knuckles, are also similar in structure to the teeth on a gust front.
