Plume-like cloud ‘shot’ in front of Hawaiian Airlines flight seconds before turbulence injured 25, pilot says
The pilot, a captain on the Dec. 18 flight from Phoenix to Honolulu, said conditions were smooth and on-board weather radar showed no turbulence as they flew above a layer of cirrostratus clouds at an altitude of between 37,000 and 38,000 feet, the National Transportation Safety Board said in a preliminary report on the incident.
The pilot told the lead flight attendant about the incoming weather, and within 1 to 3 seconds, the plane — an Airbus A330 — plowed into what the report described as “severely convectively induced turbulence,” the report says.
"Shortly after the turbulence-related upset, the lead flight attendant informed the flight crew that there were multiple injuries in the cabin," the report says.
Satellite imagery later reviewed by the report’s authors showed strong cells associated with a storm system moving toward Hawaii that were near the flight path, according to the report
No other pilots had reported severe weather in the region before the incident, the report says.
Pretty high up to be turbulence caused by a ground explosion, I would think.

Hmmm...yes...too high up to be a ground explosion! When I first started reading my thought was immediately something that had occurred on the surface (volcano)!
After reading that though...my thought went to a explosion in the air! Like what though? Missile defense system? That was my thought...the term "smokey" makes me think incendiary of some sort! Ah...a missile being shot down...is that too far fetched?
Maybe it is...but it certainly is an odd occurrence! I remember the "Star Wars" missile defense system introduced in the Reagan days...I thought about something like that! Did Kim Jong-un get one of his stray missiles shot down?

Hadn't even considered that. Good thought.
Seems like they would have seen an explosion or saw something on radar.
Noodle scratcher...

Maybe "they" did...lol
May not have seen the explosion...at that altitude the air is very thin and if it was much higher than the planes altitude, then "stuff" would have still been falling (descending) to the earth!
I imagine extreme heat (like nuclear fusion) would stay in the upper atmosphere and remain hot for a considerable amount of time! I am certainly not an expert (not even an armature) in how something like that might look or be described...I'm just guessing really!
Some of these updrafts or upward motions can be 40 mph or more, so nothing can be there and then in a matter of minutes you can have a well-developed cloud in front of you,” said Derek Wroe, a National Weather Service meteorologist.

It wasn’t a smoke cloud, that was just the way he described it. It was “similar to a smoke cloud”. It was most likely a shear line that formed as they approached the area, and warm air pushed the cloud up.
Clouds with vertical growth include cumulus and cumulonimbus clouds. These clouds grow high up into the atmosphere rather than spreading across the sky. They span all levels of the troposphere and can even rise up into the stratosphere.
Clouds with vertical growth develop by warm air rising from the surface. Cumulus and cumulonimbus clouds provide the some of the most interesting and severe weather on Earth.

If it was a shear line, there was insane force behind it. Windshear has knocked large planes, like L1011s out of the air, when they were on approach. At high altitude it can cause insane turbulence. A United 747 out of Japan hit turbulence from one that resulted in one death, and enough damage that they retired the plane a year early.

I don't recall ever hearing or seeing a cloud climbing vertically like a puff of smoke. Expand upwards, sure. But need rise straight up. Not saying I think you're wrong, or that I couldn't wrap my mind around what you explained. I just have never seen anything like that before. I bet that was wild watching a cloud climb like that with that much force underneath it. Freaky either way.

I did just find this. Vertical growth clouds.

Wild. I learn something new every day. This thing must've been a powerful surge behind it.
