In general, three bands developed, and the eastern band in particular generated a number of tornado warnings as embedded cells acquired rotating updrafts.
An unstable air mass and humid air mass, for one, which provided the buoyant energy for strong cloud updrafts.
These could rob rising cloud updrafts of some of their buoyancy, weakening thunderstorm cells.
If a thunderstorm cell was able to get going, then those strong wind changes could impart a spin to the updraft.
Instead, their water evaporates, creating a humid layer that makes it easier for air to rise quickly through the atmosphere as strong, storm-brewing updrafts.
Joe had found a strong updraft where a wind ran up the side of a mountain.
They got the wind against their nose and started a humming dive, feeling in the alien updraft for the obstruction which caused it.
I could stand to have another hit ready when Updraft petered out.
Parodisiac was much too good to hold for the closing of Updraft.
Hail appears to be formed in the violent updraft of air at the front of a thunderstorm.
