My Twitter feed exploded with pictures of a quaint little cumulonimbus cloud that developed near Smith Lake around 6:30 PM and moved north dissipating between Hartselle and Falkville by 8 PM:
The shape of the cloud is called an “anvil;” it gets that way because the updraft in the thunderstorm gets high enough to either get sheared off by upper-level winds, and/or it hits the tropopause and spreads out. In this case, it’s more than likely stronger winds aloft helping to push the anvil outward away from the main updraft.
Check out some of the awesome shots!
