Florida visible satellite imagery shows a large canopy top of thunderstorm anvil clouds spreading out over the western Atlantic. Beneath these clouds was a large area of rain and embedded thunderstorms. A second wave of thunderstorm clouds can be seen approaching the west coast of Florida. Note the bubbly appearance of the clouds west of Tampa. These ‘overshooting tops’ clouds represent strong updrafts penetrating through the top of the lower portion of the atmosphere and are indicative of strong to severe thunderstorms. Much drier air behind a cold front is marked by the rapid decrease in the clouds over Northwest Florida.
